## Expert advice on a mortgage declined at underwriting

Speak to a Mortgage Lane adviser about your options.

## In short

A mortgage declined at underwriting has passed the lender's automated checks and then been refused by a person who has read your documents. The findings behind a decline include income lower or less certain than declared, undisclosed payments on bank statements, spending such as gambling, or a job, income type or deposit outside the lender's policy. Better evidence or another lender can put some of these right, while others take time to change.

## What is a mortgage declined at underwriting?

**A mortgage declined at underwriting has passed the lender's automated checks and been refused by an [underwriter](https://mortgagelane.com/definitions#def-underwriting) who has read the documents, such as payslips, tax calculations, bank statements, identification and the [valuation](https://mortgagelane.com/definitions#def-mortgage-valuation), and found something that does not match the application or does not fit the lender's policy.** Underwriters decline on findings such as income that is lower or less certain than declared, commitments in bank statements that were not disclosed, patterns of spending such as gambling or frequent short-term borrowing, an employment or income type outside policy, or a credit or property issue. Some findings can be fixed with better evidence or a lender with a different policy, but a finding that reflects an [affordability](https://mortgagelane.com/definitions#def-affordability) or conduct issue will follow the case to any lender.

The lender's automated decision engine often scores an application first, on the declared income and outgoings and a [credit search](https://mortgagelane.com/definitions#def-credit-search). The case then goes to an underwriter for a manual review of the application and its evidence, when the documents arrive, when the system flags a risk or when the income or credit history needs a closer look. A case can therefore look acceptable at the automated stage and fail once the underwriter compares it with the evidence. The underwriter verifies income, checks that bank statements support the declared income and commitments, applies the lender's policy on employment, income types and credit, and reviews the lender's valuation.

A mortgage on a home you will live in is normally a [regulated mortgage](https://mortgagelane.com/definitions#def-regulated-mortgage), meeting the legal test that at least 40% of the property is used as a dwelling ([legislation.gov.uk: Regulated Activities Order, article 61](https://www.legislation.gov.uk/uksi/2001/544/article/61)). Residential underwriting must follow the [Financial Conduct Authority](https://mortgagelane.com/definitions#def-financial-conduct-authority)'s responsible lending rules in [MCOB](https://mortgagelane.com/definitions#def-mcob). The lender must obtain evidence of the income the customer declares, of a type and for a period adequate to support each part of it, and must not accept self-certification of income ([FCA Handbook: MCOB 11.6.8R](https://www.handbook.fca.org.uk/handbook/MCOB/11/6.html)). It must also take reasonable steps to find out the customer's actual outstanding commitments, and the FCA's guidance gives a [credit reference agency](https://mortgagelane.com/definitions#def-credit-reference-agency) search as one way to corroborate what the customer declares (MCOB 11.6.12R and 11.6.13G). Because the rules require the lender to lend on what the evidence shows, the underwriter compares the application with the documents line by line.

Mortgage Lane helps buyers and remortgagers declined at underwriting, including employed applicants, the self-employed, contractors, company directors and people with complex income. We read the documents the way an underwriter does, identify the finding and present the case to a lender whose policy fits, with the evidence and any explanations in place from the start. For a refusal at another stage, our hub on [declined mortgages](https://mortgagelane.com/insights/declined-mortgages) covers declines in general, and separate pages cover a [mortgage declined after application](https://mortgagelane.com/mortgages/mortgage-declined-after-application), a [mortgage declined on affordability](https://mortgagelane.com/mortgages/mortgage-declined-on-affordability), a [mortgage declined on valuation](https://mortgagelane.com/mortgages/mortgage-declined-on-valuation) and a [mortgage declined after exchange](https://mortgagelane.com/mortgages/mortgage-declined-after-exchange).

## Mortgage rates after an underwriting decline

**Mortgage rates after an underwriting decline depend on what the underwriter found, because the finding decides which lenders can consider the case.** Where another mainstream lender's policy accepts the finding, for example a lender that counts more of your overtime or accepts your type of employment contract, its normal rates apply and the earlier decline does not change the price. Complex income, a short time in a job or recent [adverse credit](https://mortgagelane.com/definitions#def-adverse-credit) narrow the market, and the case may then need a [specialist lender](https://mortgagelane.com/definitions#def-specialist-lending), whose products are priced for the criteria it accepts and are often more expensive. Lenders price by product and [loan to value (LTV)](https://mortgagelane.com/definitions#def-loan-to-value) band, so the size of the deposit matters as much after a decline as before it, and product fees vary in the same way.

The decline itself is not usually recorded on your credit file, but the credit search made for the application is ([Experian: refused a mortgage](https://www.experian.co.uk/consumer/mortgages/guides/refused-mortgage.html)). The ICO notes that lots of searches in a short space of time can suggest that you are having problems getting credit ([ICO: credit](https://ico.org.uk/for-the-public/credit/)), which is a reason to find the cause before applying again rather than trying several lenders in turn. Each credit reference agency sets how long a search stays visible. Our [fixed term mortgages](https://mortgagelane.com/mortgages/fixed-term-mortgages) page explains how fixed rates are priced.

**Declined by an underwriter?** Get in touch with the documents you submitted and anything the lender told you. We work out from them what the underwriter found before choosing where to apply next.

A refusal is not usually recorded on the credit file, but the application's hard search is; as at October 2026 Experian retains hard searches for lending decisions for a year.

## Mortgage underwriting criteria: the documents we review

**An underwriter reads each document for two things: whether it supports what the application says, and whether what it shows fits the lender's policy.** The table below sets out what underwriters look for in each document. Its income and commitments points follow the FCA's rules and its deposit row the Money Laundering Regulations, checked in October 2026. The other rows describe how lenders generally work, and each lender's policy decides a case. For employed income the evidence is payslips and the P60, which shows the tax paid on your salary in the tax year to 5 April ([GOV.UK: P60](https://www.gov.uk/paye-forms-p45-p60-p11d/p60)). The FCA's guidance says income from overtime may be evidenced by payslips over a period of time, and that the evidence a lender needs depends on how far each part of the income is contractually guaranteed ([FCA Handbook: MCOB 11.6.9G](https://www.handbook.fca.org.uk/handbook/MCOB/11/6.html)). For the self-employed, lenders read HMRC's tax calculations, the [SA302 and tax year overview](https://mortgagelane.com/definitions#def-sa302), which can be printed for the last four years once a return is filed ([GOV.UK: get your SA302 tax calculation](https://www.gov.uk/sa302-tax-calculation)), or the accounts. Company directors are assessed on salary and [dividends](https://mortgagelane.com/definitions#def-dividend-income) or a share of company profit, and an underwriter may query dividends that the company's [retained profit](https://mortgagelane.com/definitions#def-retained-profit) does not support. Our page on [limited company director mortgages](https://mortgagelane.com/mortgages/limited-company-director-mortgages) explains the method, and our [self-employed mortgages](https://mortgagelane.com/mortgages/self-employed-mortgages) page compares every structure.

Every row in the table feeds into affordability. In our experience the standard [income multiple](https://mortgagelane.com/definitions#def-loan-to-income) is 5 times income after credit commitments, up to 6 times for professionals and specialist products, so each £100 a month of commitments takes £1,200 a year off the income and £6,000 off the maximum loan at 5 times. Underwriters also run the lender's own affordability model. Under the FCA's rules that assessment must take full account of the customer's income net of tax and National Insurance, their [committed expenditure](https://mortgagelane.com/definitions#def-committed-expenditure) and the household's essential spending, and unless the rate is fixed for five years or more it must consider how interest rates may rise over at least the first five years (MCOB 11.6.5R and 11.6.18R). Our page on a [mortgage declined on affordability](https://mortgagelane.com/mortgages/mortgage-declined-on-affordability) works through that model; this page is about what the documents show.

## What underwriters look for in each document

*What underwriters look for in each document*

| Document | What underwriters look for |
| --- | --- |
| Payslips and P60 | Basic pay, overtime, bonus, commission and deductions, and whether they match the income declared |
| Tax calculations and accounts | Self-employed or director income, the trend from year to year and the tax paid |
| Bank statements | Salary credits, commitments, regular spending, returned payments, gambling and short-term loans |
| Credit file | Commitments that match the application, and any adverse credit and its age |
| Employment contract or letter | Probation, the contract end date and whether hours are guaranteed |
| Other income | Benefits, foreign currency or other income, and whether it is within the lender's policy |
| Identity and address | Names, addresses and dates that are consistent across every document |
| Deposit source | Savings history, gifts and the source of the funds |
| Valuation | The value against the price, and any property issues or conditions |

What underwriters generally look for in each document, checked 8 October 2026. The income and commitments rows follow FCA rules MCOB 11.6.8R, 11.6.9G, 11.6.12R and 11.6.13G and the deposit row the Money Laundering Regulations 2017. Underwriting policy varies by lender, and each lender's criteria decide a case.

## Common underwriting findings, and how each is assessed

**Underwriting findings fall into six groups, and each has a different fix, so the first job after a decline is to work out which one applies.**

### Income lower than declared

Overtime, bonus or commission may be declared in full but evidenced as variable. A lender reading [variable income](https://mortgagelane.com/definitions#def-variable-income) decides how much of it to count and over what period, and lenders differ widely: some count it in full where it is regular and evidenced, others count a share or average it over one or two years, and some leave it out. The same payslips can therefore support different figures at different lenders. Lenders read self-employed income from [net profit](https://mortgagelane.com/definitions#def-net-profit) and may average it, so a strong latest year counts for less with a lender that averages; our page on [mortgages with decreasing profits](https://mortgagelane.com/mortgages/mortgages-with-decreasing-profits) covers the reverse case. Deductions on the payslip matter as well, because the FCA's rules work from income net of tax and National Insurance, and a [student loan](https://mortgagelane.com/definitions#def-student-loan-repayment-plan) deduction is one the underwriter will see.

The fix is usually evidence and the choice of lender. Payslips and P60s covering the period a lender asks for can support a higher figure with a lender that counts more of the variable pay, and the worked example below shows how far the reading moves the maximum loan. A [contractor](https://mortgagelane.com/definitions#def-contractor-mortgage) paid a day rate can be assessed on the contract instead, and in our experience lenders that do so annualise the rate over 48 weeks (see [contractor mortgages](https://mortgagelane.com/mortgages/contractor-mortgages)). Our page on a [mortgage for a £50k salary](https://mortgagelane.com/insights/mortgage-for-50k-salary) works the same multiples on employed income.

**Get in touch** with your payslips, P60s or tax calculations.

### Undisclosed commitments

Bank statements can show regular payments that were not on the application: car finance, buy now pay later plans, loans from family, childcare. Each one changes affordability, and an underwriter who finds one also has to decide why it was left off. The FCA's guidance expects a lender to corroborate the commitments a customer declares, for example by a credit reference agency search or by checking statements (MCOB 11.6.13G), so a payment left off the form is likely to be found. Some commitments never appear on a credit file, such as a loan from a relative or a childcare contract, and the statements are where the underwriter sees them. At 5 times income, each £100 a month of payments that was not declared removes £6,000 of borrowing once it is found, and the inconsistency itself can lead an underwriter to decline even where the corrected figures would still pass.

**Get in touch** with a full list of your regular payments.

### Gambling, payday loans and spending patterns

Frequent gambling transactions, short-term loans, unarranged overdrafts or returned payments can lead an underwriter to decline on conduct grounds even where affordability passes, because they read as signs of financial strain. Lenders vary in how they treat occasional small transactions, and a sustained period of statements without them helps a later application. Payday and other short-term loans on the credit file or the statements suggest reliance on expensive credit. Some lenders want them repaid and a period without them before they will lend, and how long that period is varies by lender. Our guide to a [refused mortgage due to gambling](https://mortgagelane.com/guides/declined-mortgages/refused-mortgage-due-to-gambling) looks at how lenders read gambling transactions in more detail.

If gambling has become hard to control, free and confidential support is available, including the National Gambling Helpline, which the NHS lists with its other help ([NHS: help for problems with gambling](https://www.nhs.uk/live-well/addiction-support/gambling-addiction/)). Mortgage Lane does not give debt advice.

**Get in touch** with your recent bank statements.

### Employment or income type outside policy

Lenders set policy on how long you have been in a job and on what terms. A probation period, a short contract, zero-hours work or recent self-employment can fall outside one lender's policy and inside another's. In our experience specialist lenders accept [fixed term contract](https://mortgagelane.com/definitions#def-fixed-term-contract-mortgage) workers with no track record and during probation, while high street lenders prefer 6 to 12 months; our page on [fixed term contract mortgages](https://mortgagelane.com/mortgages/fixed-term-contract-mortgages) covers that case. A zero-hours contract is one where the employer does not have to offer work and the worker does not have to accept it ([GOV.UK: zero-hours contracts](https://www.gov.uk/contract-types-and-employer-responsibilities/zero-hour-contracts)), and how the earnings are read varies by lender, as our guide to a [mortgage on a zero hour contract](https://mortgagelane.com/insights/mortgage-on-a-zero-hour-contract) explains. Recent self-employment is a question of [trading history](https://mortgagelane.com/definitions#def-trading-history), covered on our page on [one year self-employed mortgages](https://mortgagelane.com/mortgages/one-year-self-employed-mortgages). Some lenders also exclude income types that others accept, such as certain benefits or income paid in a foreign currency.

**Get in touch** with your contract and employment history.

### Deposit source

A deposit that cannot be traced, includes borrowed money or comes from a source the lender does not accept can lead to a decline whatever the affordability. Lenders carry out [anti-money laundering](https://mortgagelane.com/definitions#def-anti-money-laundering) checks under the Money Laundering Regulations, which require them to identify and verify the customer and to scrutinise transactions, including where necessary the source of funds ([legislation.gov.uk: Money Laundering Regulations 2017, regulation 28](https://www.legislation.gov.uk/uksi/2017/692/regulation/28)), so a large unexplained credit on the statements will be queried, and money sent from overseas can need more evidence of where it came from. A clear savings history, a gift letter or a sale proceeds statement supports the deposit. For a [gifted deposit](https://mortgagelane.com/definitions#def-gifted-deposit) the lender looks for a gift letter from the giver and evidence of where the giver's money came from, which our page on [gifted deposit mortgages](https://mortgagelane.com/mortgages/gifted-deposit-mortgages) sets out. Money that has to be repaid is a loan, which a lender may refuse as the deposit or count as a commitment.

**Get in touch** with the deposit's history.

### Inconsistencies between documents

Addresses, dates of employment or figures that differ between documents need explaining. Some are innocent errors, such as a previous address entered with the wrong dates or an income figure taken from the wrong payslip, but all are queried and some lead to a decline, because the FCA's rules require the lender's income evidence to be subject to appropriate anti-fraud controls (MCOB 11.6.8R). An underwriter treats an inconsistency you have explained and evidenced in advance differently from one they find for themselves. The application has to be accurate, and a mortgage broker must submit the information it obtains from you accurately to the lender ([FCA Handbook: MCOB 11A.1.1R](https://www.handbook.fca.org.uk/handbook/MCOB/11A/1.html)), so the fix for an inconsistency is to correct it and evidence the right figure.

**Get in touch** with the details.

At 5 times income, the standard multiple in Mortgage Lane's experience, each £100 a month of undeclared payments removes £6,000 of borrowing once found, and the omission alone can lead to a decline.

## What do mortgage underwriters look for?

**Mortgage underwriters work through seven checks on a residential case, and a decline can come from any one of them.**

1. **Identity and address.** Consistent across all documents, and verified under the anti-money laundering rules.
2. **Income.** Verified against payslips, P60s, tax calculations, accounts or contracts, with each part of the income counted under the lender's policy.
3. **Affordability.** Income against commitments and household spending, at the lender's stressed rate.
4. **Bank conduct.** Salary received, commitments, overdraft use, gambling and short-term lending.
5. **Credit.** The commitments on the credit file match the application, and any adverse credit is within policy.
6. **Deposit.** Its source and history.
7. **Property.** The valuation and any conditions it carries.

### The mortgage underwriting process

The mortgage underwriting stage starts once a full application is made, usually after an [agreement in principle](https://mortgagelane.com/definitions#def-agreement-in-principle), which is an early indication based mainly on what you declare and a credit search. With the full application the lender receives the documents, instructs the valuation and passes the case to an underwriter. Valuation and underwriting can run in parallel, so a case can pass one and fail the other, and a [down valuation](https://mortgagelane.com/definitions#def-down-valuation) raises the loan to value on the same loan. The property itself can also fall outside the lender's policy, for example because of a short lease, a complex title or how much the lender has already lent in the same development. The underwriter may approve the case, ask questions, ask for more documents or decline. How long this takes varies by lender and by case: a straightforward application with complete, consistent documents can be decided quickly, while complex income, a valuation query or unanswered questions add time. Some lenders recheck credit before completion, so new borrowing or [missed payments](https://mortgagelane.com/definitions#def-missed-payment) after the offer can still cause problems, as our guide to a [mortgage declined before completion](https://mortgagelane.com/guides/declined-mortgages/mortgage-declined-before-completion) explains.

### Credit scoring and the underwriter

A credit score decline, unlike an underwriting decline, is made by the lender's automated scoring on the credit file and the application, often before an underwriter has read anything. A lender that rejects an application must tell you without delay and say where the decision was based on automated processing of data ([FCA Handbook: MCOB 11A.3.3R](https://www.handbook.fca.org.uk/handbook/MCOB/11A/3.html)). Our guide to a [mortgage declined on credit score](https://mortgagelane.com/guides/declined-mortgages/mortgage-declined-on-credit-score) and our page on [low credit score mortgages](https://mortgagelane.com/mortgages/low-credit-score-mortgages) cover that route. The underwriter reads credit in more detail: whether the accounts on the file match the commitments declared, how much of the available credit on cards and overdrafts is in use, any [financial associations](https://mortgagelane.com/definitions#def-financial-association) with another person, and the age and size of any [county court judgments](https://mortgagelane.com/definitions#def-county-court-judgment), [defaults](https://mortgagelane.com/definitions#def-credit-default) or missed payments, which our pages on [CCJ mortgages](https://mortgagelane.com/mortgages/ccj-mortgages), [mortgages with defaults](https://mortgagelane.com/mortgages/mortgages-with-defaults) and [mortgages with missed payments](https://mortgagelane.com/mortgages/mortgages-with-missed-payments) cover entry by entry.

### Several risks together

An underwriter also looks at the case as a whole. Several moderate risks together, such as a high loan to income, a high loan to value, a recent credit problem and complex income, can take a case outside a lender's appetite even where each would be acceptable on its own. A decline of that kind is about policy rather than any single finding, and another lender whose appetite is different may read the same case another way. Reducing one of the risks, for example with a larger deposit, can also change the answer.

## What to do if your mortgage is declined by an underwriter

**After a decline by an underwriter, work out what the underwriter found before doing anything else, because applying again on the same evidence is likely to get the same answer.**

- **Identify the finding.** Ask the lender which area caused the decline. Lenders do not always give detailed reasons, but some will say whether it was income, affordability, credit or policy, more readily when asked through a broker. Under the FCA's rules, where the rejection rested on a database search such as a credit reference agency, the lender must give you the result and the particulars of the database it consulted (MCOB 11A.3.3R). The ICO says that if you think you were refused unfairly you can ask the lender to explain the main reason and review its decision.
- **Review your documents** as an underwriter would: payslips against the declared income, every regular payment on the statements against the application, and addresses and dates across every document. A statutory credit report is free from each of the main credit reference agencies, and the ICO says no fee is needed for one.
- **Fix what is fixable.** Add evidence, disclose commitments fully and correct errors.
- **Change lender** where the issue is policy, such as how much variable pay is counted, how long you have been in the job or the type of income.
- **Wait** where the issue is conduct, such as recent gambling or short-term borrowing, until the statements show a cleaner pattern.

Applying to several lenders in quick succession without changing anything adds credit searches and is likely to repeat the decline. After a policy decline, for example over the type of income rather than a failure of affordability, another lender may accept the case as it stands. If the problem was the documents, correcting the evidence and applying again with the corrections explained may be enough. An affordability decline means the loan, the deposit or the commitments have to change, and our page on a [declined application](https://mortgagelane.com/mortgages/mortgage-declined-after-application) sets out the wider options.

## How a mortgage after an underwriting decline is arranged

1. **Document review.** Every document checked against the application: payslips, P60s or tax calculations, bank statements, the credit reports, identification, the deposit trail and anything the lender said about the decline.
2. **Finding identified.** Income, commitments, conduct, policy, deposit or property, and whether it can be fixed now, needs a different lender or needs time.
3. **Lender matched.** A lender whose policy accepts the case on the corrected figures, including how it reads variable pay, the type of employment and the deposit.
4. **Full disclosure upfront.** Every commitment declared, and explanations for anything unusual, such as a large credit, a gap in employment or a one-off payment, submitted with the application.
5. **Underwriter queries answered** quickly, with evidence.

## A mismatch between the application and the documents: the underwriting arithmetic

**An illustrative employed applicant declared £52,000 of income, including £10,000 of overtime, and two credit cards, and the underwriter declined.** The figures are hypothetical and are not any lender's terms or an offer.

### Step 1. What was declared and what the underwriter found

The applicant is buying a £287,500 home with a £57,500 deposit, so the loan applied for is £230,000 at 80% loan to value. The application declared a £42,000 basic salary, £10,000 of overtime (the amount earned in the latest year) and two credit cards with no balance carried. The payslips and P60s showed overtime of £2,000 in the earlier year and £10,000 in the latest, and the lender in this illustration counts 50% of a two-year average of overtime. The bank statements also showed car finance of £320 a month that was not on the application. The multiple is 5 times income after commitments, the standard in Mortgage Lane's experience.

## Step 1 figures

*Step 1 figures*

| Item | Declared on the application | Found by the underwriter |
| --- | --- | --- |
| Basic salary | £42,000 | £42,000, matching the payslips and P60 |
| Overtime | £10,000, the latest year | £2,000 and £10,000 in the last two years; 50% of the £6,000 average counted, £3,000 |
| Income used | £52,000 | £45,000 |
| Credit commitments | Two credit cards, no balance carried | The two cards, plus car finance of £320 a month on the bank statements |
| Commitments a year | £0 | £3,840 |
| Maximum loan at 5 times | £260,000 | £205,800 |
| Loan applied for | £230,000 | £230,000 |
| Outcome | Passes on the declared figures | £24,200 short; declined on lower income and higher commitments |

Hypothetical figures for illustration. The 50% share of a two-year average is an illustrative lender reading, not any lender's term. 5 times is the standard multiple in Mortgage Lane's experience, not a lender term.

### Step 2. Four readings of the same payslips

The table reads the same pay and commitments four ways and sets each result against the £230,000 loan. The first row is the application as declared, and the other three include the car finance, as a lender would once it knows about it.

## Step 2 figures: four readings of the same payslips

*Step 2 figures: four readings of the same payslips*

| Reading | Income counted | Commitments a year | Maximum loan at 5 times | Against the £230,000 loan |
| --- | --- | --- | --- | --- |
| As declared: the latest year's overtime in full, car finance left out | £52,000 | £0 | £260,000 | £30,000 to spare |
| 50% of the two-year overtime average (the underwriter's reading) | £45,000 | £3,840 | £205,800 | £24,200 short |
| 100% of the two-year overtime average | £48,000 | £3,840 | £220,800 | £9,200 short |
| Basic salary only | £42,000 | £3,840 | £190,800 | £39,200 short |

Illustrative arithmetic on hypothetical figures, worked with the calculator on this page. The readings are examples of how lenders differ, not lender terms; 5 times is the standard multiple in Mortgage Lane's experience, and a lender's affordability model can reduce any figure. Not an offer of finance.

On the declared figures the case passes with £30,000 to spare. The underwriter's reading supports £205,800, £24,200 short, so the application fails on the lower income and the higher commitments together. Of the £54,200 gap between the two, the car finance accounts for £19,200 (£320 a month is £3,840 a year, and at 5 times that is £19,200 of borrowing) and the overtime reading for £35,000 (£7,000 less income at 5 times).

### Step 3. The fixes

The next application presents the same facts accurately, to a lender whose policy reads them more fully.

## Step 3 figures: the fixes

*Step 3 figures: the fixes*

| Fix | Effect |
| --- | --- |
| A lender counting 100% of regular overtime with two years' evidence | Income used rises from £45,000 to £48,000, towards the declared £52,000, and the maximum loan from £205,800 to £220,800 |
| Car finance disclosed upfront | No inconsistency between the application and the statements; the £3,840 a year is assessed from the start |
| Loan amount reviewed | Set to what the corrected figures support, £220,800, with £9,200 more deposit or a lower price |

Illustrative arithmetic on hypothetical figures, worked with the calculator on this page. Lender policies on overtime and commitments vary. Not an offer of finance.

With a lender that counts all of a two-year average, and the car finance declared from the start, the case supports £220,800 and falls £9,200 short of the loan applied for. It could be presented with a £66,700 deposit on the same £287,500 home, at about 76.8% loan to value, or at a lower price, subject to the lender's own underwriting. Over 30 years at 5.2%, the illustrative rate used across our guides, which is not a product rate, the monthly payment is £1,212.44 on £220,800 against £1,262.96 on £230,000. Basic salary alone would support £190,800, the floor if a lender counted no overtime at all.

The decline came from how the overtime was read and from a commitment left off the form, and creditworthiness played no part in it. Presented accurately to a lender whose overtime policy suits the payslips, the case may be accepted, sometimes at a slightly lower loan. Lender policies on overtime and commitments vary, and the readings here are illustrations, not any lender's terms.

### What decides the case

Declare everything, evidence variable income properly, and match the case to a lender whose policy reads it accurately. Those are the parts of the case an applicant can still change, because the figures on the payslips and statements are fixed once they are issued. Our [declined mortgages](https://mortgagelane.com/insights/declined-mortgages) hub covers the other reasons a mortgage can be refused.

## Frequently asked questions about a mortgage declined at underwriting

**Q: Why do underwriters decline mortgages?**

faq-id: why-do-underwriters-decline-mortgages

A mortgage is declined by an underwriter when the documents show something different from the application or something outside the lender's policy. The findings behind a decline include income that is lower or less certain than declared, commitments on bank statements that were not disclosed, gambling or short-term borrowing on the statements, an employment or income type the lender does not accept, or a deposit or property issue. For a residential mortgage the underwriter applies the FCA's responsible lending rules, which require the lender to obtain evidence of the income it relies on ([FCA Handbook: MCOB 11.6](https://www.handbook.fca.org.uk/handbook/MCOB/11/6.html)). Better evidence or a lender with a different policy can fix some findings, while an affordability or conduct issue needs time to change.

**Q: What do mortgage underwriters look for?**

faq-id: what-do-mortgage-underwriters-look-for

Mortgage underwriters look for income that matches the evidence, commitments that match the credit file and bank statements, sensible bank conduct, a traceable deposit, consistent identity and address details, credit history within the lender's policy, and a property that is suitable security at the agreed value. They read payslips or tax calculations, recent bank statements, the credit file, identification, the deposit trail and the lender's valuation. Each lender applies its own policy to what it finds, so the same documents can pass at one lender and fail at another. Underwriters also look at the case as a whole, because several moderate risks together can take it outside a lender's appetite.

**Q: Can I reapply after an underwriting decline?**

faq-id: can-i-reapply-after-an-underwriting-decline

You can reapply after an underwriting decline once the finding is identified. Where it is a policy issue, such as how much overtime a lender counts or how long you have been in a job, another lender may accept the same case. Where it is a conduct issue, such as recent gambling or short-term borrowing, you may need to wait for a cleaner run of bank statements first. Applying again straight away on the same evidence risks another decline and another credit search, and the ICO notes that lots of searches in a short space of time can suggest you are having problems getting credit ([ICO: credit](https://ico.org.uk/for-the-public/credit/)).

**Q: Do underwriters check bank statements?**

faq-id: do-underwriters-check-bank-statements

Underwriters usually check recent bank statements to confirm salary credits, find commitments that are not on the credit file, and review spending patterns such as gambling, short-term loans, overdraft use and returned payments. The FCA's guidance expects a lender to corroborate the commitments a customer declares, and checking statements is one way of doing so ([FCA Handbook: MCOB 11.6](https://www.handbook.fca.org.uk/handbook/MCOB/11/6.html)). How many months of statements a lender asks for varies by lender. Unexplained transactions, such as a large credit or regular payments to a person, may lead to questions, so explaining them before the underwriter asks saves time.

**Q: What is mortgage underwriting?**

faq-id: what-is-mortgage-underwriting

Mortgage underwriting is the lender's detailed assessment of an application, in which an underwriter verifies identity, income, commitments, bank conduct, credit history, the deposit source and the valuation against the application and the lender's policy before deciding whether to make an offer. For a residential mortgage it follows the FCA's responsible lending rules, which require the lender to obtain evidence of the income declared and not to accept self-certification of income ([FCA Handbook: MCOB 11.6](https://www.handbook.fca.org.uk/handbook/MCOB/11/6.html)). An application can be scored automatically first, with an underwriter reviewing the documents once they are submitted or when the case needs a closer look.

**Q: Will the lender tell me why the underwriter declined?**

faq-id: will-the-lender-tell-me-why-the-underwriter-declined

Lenders do not always give detailed reasons for an underwriting decline, but some will say whether it related to income, affordability, credit or policy, especially when asked through a broker. Under the FCA's rules a lender must tell you without delay that the application has been rejected and, where the decision rested on a database search such as a credit reference agency, give you the result and the particulars of the database ([FCA Handbook: MCOB 11A.3.3R](https://www.handbook.fca.org.uk/handbook/MCOB/11A/3.html)). The ICO says that if you think you were refused unfairly, you can ask the lender to explain the main reason and review its decision ([ICO: credit](https://ico.org.uk/for-the-public/credit/)). Reviewing your documents against the application can usually identify the issue as well.

**Q: Can undisclosed debts cause a mortgage decline?**

faq-id: can-undisclosed-debts-cause-a-mortgage-decline

Debts or regular payments found on bank statements or the credit file but not declared on the application can cause a decline, both because they reduce affordability and because the inconsistency raises concern. Lenders are expected to corroborate the commitments a customer declares, for example by a credit reference agency search or a check of statements, so an undeclared payment is likely to be found. At 5 times income, the standard multiple in our experience, each £100 a month of payments removes £6,000 of borrowing. Declaring every commitment on the application avoids the inconsistency.

**Q: Can overtime and bonus income cause an underwriting decline?**

faq-id: can-overtime-and-bonus-income-cause-an-underwriting-decline

Overtime and bonus income can cause an underwriting decline where the application relies on the full amount and the lender counts only part of it. Lenders differ widely: some count variable pay in full where it is regular and evidenced, some count a share, some average it over one or two years and some leave it out, and commission is treated in the same way. The FCA's guidance notes that overtime may be evidenced by payslips over a period of time ([FCA Handbook: MCOB 11.6.9G](https://www.handbook.fca.org.uk/handbook/MCOB/11/6.html)). For example, £10,000 of overtime declared in full but counted as £3,000 lowers the maximum loan by £35,000 at 5 times income.

**Q: Can gambling on bank statements stop a mortgage?**

faq-id: can-gambling-on-bank-statements-stop-a-mortgage

Regular or significant gambling transactions on bank statements can lead an underwriter to decline, even if affordability passes, because they suggest financial risk. Lenders vary in how they treat occasional small transactions, and a sustained period of statements without gambling helps a later application. Spending on gambling also reduces the income left over each month, which the lender's affordability assessment takes into account. If gambling has become hard to control, free and confidential support is available through the National Gambling Helpline, which the NHS lists with its other help ([NHS: help for problems with gambling](https://www.nhs.uk/live-well/addiction-support/gambling-addiction/)).

**Q: Can payday loans affect a mortgage application?**

faq-id: can-payday-loans-affect-a-mortgage-application

Payday and other short-term loans on your credit file or bank statements can lead lenders to decline, because they suggest reliance on expensive credit. Some lenders want them repaid and a period without them before you apply, and how long that period is varies by lender. How recent and how frequent the loans were matters to the underwriter. A loan that is still running is also a commitment, which reduces the income left for the mortgage in the lender's affordability assessment.

**Q: How long does mortgage underwriting take?**

faq-id: how-long-does-mortgage-underwriting-take

How long mortgage underwriting takes varies by lender and by case. A straightforward application with complete, consistent documents can be decided quickly, while complex income, a valuation query or unanswered questions from the underwriter add time. Valuation and underwriting can run at the same time. Submitting every document at the start, with explanations for anything unusual such as a large deposit into your account or a gap in employment, usually shortens the process because the underwriter has fewer queries to raise.

**Q: What is the difference between a credit score decline and an underwriting decline?**

faq-id: what-is-the-difference-between-a-credit-score-decline-and-an-underwriting-decline

A credit score decline is made automatically by the lender's scoring system, based on your credit file and the application, while an underwriting decline is made by a person who has reviewed your documents. Underwriting declines usually relate to income, commitments, conduct or policy. Under the FCA's rules a lender that rejects an application must tell you without delay and say where the decision was based on automated processing of data ([FCA Handbook: MCOB 11A.3.3R](https://www.handbook.fca.org.uk/handbook/MCOB/11A/3.html)). The two need different responses: a scoring decline points to the credit file, and an underwriting decline to the evidence and the lender's policy.

**Q: Can my job cause a mortgage to be declined at underwriting?**

faq-id: can-my-job-cause-a-mortgage-to-be-declined-at-underwriting

An underwriter may decline because of employment outside the lender's policy, such as a probation period, a short contract, zero-hours work or recent self-employment. Other lenders may accept the same employment, so the case turns on finding a lender whose policy fits. In our experience specialist lenders accept fixed-term contract workers with no track record and during probation, while high street lenders prefer 6 to 12 months. Self-employed applicants are assessed on their trading history and their tax calculations or accounts, and each lender sets its own minimum.

**Q: Can my deposit cause an underwriting decline?**

faq-id: can-my-deposit-cause-an-underwriting-decline

A deposit whose source cannot be evidenced, includes borrowed money, or comes from a source the lender does not accept can lead to a decline. Lenders must carry out anti-money laundering checks, which include scrutiny of where funds come from where necessary ([legislation.gov.uk: Money Laundering Regulations 2017, regulation 28](https://www.legislation.gov.uk/uksi/2017/692/regulation/28)). A clear savings history, a gift letter from the giver or a sale proceeds statement supports the deposit. Money that has to be repaid is a loan, which a lender may refuse as the deposit or count as a commitment.

**Q: Can a mortgage be declined at underwriting after a valuation?**

faq-id: can-a-mortgage-be-declined-at-underwriting-after-a-valuation

A mortgage can be declined at underwriting after a valuation if the valuer reports a lower value, a property defect or construction the lender does not accept, or if underwriting of income or credit finds an issue at the same time. Valuation and underwriting can run in parallel, so a case can pass one and fail the other. A lower valuation raises the loan to value on the same loan, which can take it outside the lender's limit or into a different price band, and a larger deposit or a lower price may then be needed.

**Q: Can small inconsistencies cause an underwriting decline?**

faq-id: can-small-inconsistencies-cause-an-underwriting-decline

Inconsistencies between documents, such as different addresses, employment dates or figures, can lead an underwriter to decline or to ask questions. Innocent errors can usually be explained, but they should be corrected before applying. The FCA's rules require a lender's income evidence to be subject to appropriate anti-fraud controls ([FCA Handbook: MCOB 11.6.8R](https://www.handbook.fca.org.uk/handbook/MCOB/11/6.html)), so an underwriter cannot ignore a figure that does not match. Checking every document against the application before it is submitted avoids many of these queries.

**Q: Should I explain things before the underwriter asks?**

faq-id: should-i-explain-things-before-the-underwriter-asks

Explaining unusual items upfront, such as a large deposit into your account, a gap in employment or a one-off payment, saves time and shows the lender you are being open with it. Underwriters are more comfortable with an explained item than with one they discover themselves. An explanation is stronger with evidence attached, such as a gift letter for money from family or the paperwork behind a one-off payment. A broker submits the explanations with the application and must pass on the information you give accurately to the lender.

**Q: Does being declined a mortgage affect your credit rating?**

faq-id: does-being-declined-a-mortgage-affect-your-credit-rating

Being declined is not recorded on your credit file as a decline and does not itself lower your score ([Experian: refused a mortgage](https://www.experian.co.uk/consumer/mortgages/guides/refused-mortgage.html)), but the hard search from the application is recorded, and other lenders can see it. As at October 2026, Experian keeps hard searches for one year for lending decisions ([Experian: data retention](https://experian.co.uk/legal/crain/data-retention)), and Equifax keeps search footprints other than debt collection searches for one year ([Equifax: data retention](https://www.equifax.co.uk/crain/retention)). Each agency sets its own periods. Several hard searches in a short period can count against future applications, because they can suggest you are struggling to get credit, so finding the reason for a decline before reapplying keeps the number of searches down.

**Q: Do underwriters check my credit file again?**

faq-id: do-underwriters-check-my-credit-file-again

Underwriters review the credit file obtained at application and check that the commitments on it match those declared. Some lenders recheck credit before completion, so new borrowing or missed payments after the offer can cause problems. Keeping up every payment and avoiding new credit until the purchase completes keeps the file as the underwriter saw it. Underwriters may also ask about an entry they do not recognise from the application, such as a new account opened while the case is in progress.

**Q: Can a broker help after an underwriting decline?**

faq-id: can-a-broker-help-after-an-underwriting-decline

A broker can review your documents as an underwriter would, identify the likely finding, gather the evidence the next lender needs and match the case to a lender whose policy fits. The next application then goes in with every commitment declared and an explanation for every unusual item. A broker cannot change what the documents show, and the FCA's rules require it to submit the information it obtains from you accurately to the lender ([FCA Handbook: MCOB 11A.1.1R](https://www.handbook.fca.org.uk/handbook/MCOB/11A/1.html)).
