Contractor Mortgages

What is a contractor mortgage?

Lenders that offer contractor mortgages treat the contract as the evidence of income. The contract evidences the day rate and the term; the lender also looks at the contracting history and renewals, the structure through which you are paid (limited company, umbrella company, agency PAYE or fixed-term employment) and any gaps between contracts. The mortgage itself is a standard regulated residential loan under the Financial Conduct Authority's MCOB rules, and lenders differ in how they assess the income.

IR35, the off-payroll working rules (gov.uk guidance), is a tax status. It decides who deducts income tax and National Insurance. Lenders' published rules turn on how you are paid: through your own company, an umbrella or PAYE. Some contractors move to an umbrella company when an engagement is inside IR35, and lenders treat umbrella pay differently from day-rate income through a limited company, so the pay route can change both the documents a lender reads and the figure it uses.

Contractor mortgage rates

Contractor mortgage rates depend on the lender, the product and the loan-to-value (LTV), and many contractor cases can use a lender's standard residential products, priced at the loan-to-value of the purchase by lenders that underwrite contract income. Lenders differ most in how they assess the income. An adviser compares the lenders whose contractor rules fit on rate, fees and term, and on their rules on annualisation, contract history and gaps.

Contractor mortgage criteria

Lenders set their own contractor rules, and they differ on most of the lines below. Named examples in the table come from each lender's own published criteria, checked 29 September 2026 (Aldermore: July 2026 criteria guide). Each is one lender's current rule, which can change, and none is a list of the lenders Mortgage Lane uses or a decision on any application. Lines that mention Mortgage Lane describe our own working approach from experience of the lenders we use.

Types of contractor, and how each is assessed

How the money reaches you decides which evidence, beyond the contract, the lender asks for.

Day-rate contractors through a limited company

The classic contractor runs a personal service company that invoices the client or agency at a day rate, inside or outside IR35. Lenders with a contractor route usually annualise the day rate rather than reading the company's retained profits or the director's salary and dividends, which can give a higher figure, and they ask for the current contract, contracting history and business bank statements. A contractor who does not meet a lender's contractor rules may be assessed as self-employed on accounts or tax calculations instead; whether a contractor can choose the reading that gives the higher figure is a lender check.

Get in touch with your contract and company bank statements for a day-rate assessment.

Umbrella company contractors

Contractors paid through an umbrella company receive payslips showing employment income after the umbrella's margin and deductions; some contractors use an umbrella when an engagement is inside IR35. Lenders differ: Virgin Money deducts employer National Insurance, Apprenticeship Levy and payroll costs before annualising, NatWest and Aldermore use the income after the umbrella's deductions or expenses, Halifax uses the lower of the contract value and payslip income, and Bath does not accept umbrella income (published criteria checked 29 September 2026). The evidence is the umbrella payslips, the contract and the umbrella's statements.

Get in touch with your umbrella payslips and the underlying contract.

Fixed-term and agency PAYE contractors

Fixed-term contracts and agency PAYE engagements are employment with an end date. Lenders with a fixed-term route assess the payslips as employed income where the contract has a minimum term remaining or a history of renewals, and treat the employment as continuing where the pattern supports it. Professionals on rolling fixed-term contracts (NHS, education, public sector) fall here; our fixed term contract mortgages page covers them in more detail. Supply teachers paid through agencies and umbrella companies are covered on our mortgages for teachers page.

IT contractors

Most lenders assess IT contractors under their general contractor rules, but a few have IT-specific rules: Halifax can treat an IT contractor as employed at any income level, while Bath asks for three years of IT consultant earnings (published criteria checked 29 September 2026). The specifics are on our IT contractor mortgages page.

Construction Industry Scheme (CIS) subcontractors

Construction subcontractors are paid under the Construction Industry Scheme, with tax deducted at source by the contractor (20% if registered, 30% if not), unless they hold HMRC gross payment status and are paid without deduction. Lenders assess CIS income in different ways: some annualise recent CIS payslips or statements, some deduct materials or expenses, and some assess CIS workers as self-employed on tax calculations or accounts. How long you have worked under CIS and how many months of evidence the lender reads are separate tests, and both vary by lender. The specifics are on our CIS mortgages page.

First-time contractors

Lenders differ on a first contract. Some consider it where the contract is in the same field as your earlier employment: Saffron considers day one contractors (those on their first contract) at its discretion with at least 1 year's experience in their contracting sector, and Aldermore accepts 24 months in the same line of work instead of 12 months' contractor history (published criteria checked 29 September 2026). Others want a contracting history first, such as Virgin Money's 2 years' contracting for contractors earning under £50,000.

Our experience: separately from those published examples, some of the lenders Mortgage Lane uses set no minimum contracting period, so a first contract can be considered, usually where the earlier employment was in the same field. That is our experience, not a market rule, and the lender's own criteria decide. First-year sole traders and company directors are covered on our one year self-employed mortgages page.

Contractors buying to let

Buy to let lending is rental led. Whatever your contractor status, a buy to let lender assesses affordability mainly on the expected rent, usually by testing it against the mortgage interest (an interest cover ratio test). Where the rent alone fails coverage, some lenders also use personal income to make up the shortfall, often called top slicing. Contractor income counts for that only where the lender's criteria accept annualised contract income as personal income. A contractor-friendly buy to let lender is one whose criteria do. The mechanics are in the buy to let mortgage guide.

Contractors with adverse credit, working abroad or on complex income

Adverse credit narrows the choice of lenders, and some specialist lenders' criteria consider contract income alongside past credit problems. Contractors who live abroad are assessed under expat rules where a lender offers them (expat mortgage guide), while UK residents who work abroad, or are paid in another currency, are assessed under each lender's residence, working-abroad and currency rules. Where income comes from a mix of contracts, employment and rent, the lender assesses each source under its own rules. Our declined mortgages page covers recovery routes.

Contractor-friendly mortgage lenders

Contractor-friendly lenders are lenders whose published rules read contract income as income, annualising the day rate, accepting umbrella and fixed-term PAYE pay (though not every lender accepts umbrella income), and setting contract-history and gap rules a working contractor can meet. They differ from each other on each of those rules: the annualisation convention (how many weeks a year the lender assumes), the minimum contracting history, the minimum remaining term on the current contract, the tolerance for gaps, and the treatment of first-time contractors and of umbrella income. A contractor declined by one lender on a six-month contracting history may be considered by another with the same facts, which is why the lender is chosen before the application, on the contractor's actual profile.

How a contractor mortgage is arranged

1. Structure and evidence. How you are paid, the current contract and its remaining term, the contracting history and CV, payslips or invoices and bank statements, and an IR35 status determination statement if the client has issued one.
2. Income assessment and lender match. The day rate annualised under each candidate lender's basis, or the PAYE figure, set against the loan required; the lender is chosen on its history, gap and first-time-contractor rules.
3. Agreement in principle and full application. A decision in principle on the assessed income, then the full application with the contract and evidence pack, and the lender's valuation.
4. Offer and completion. The mortgage offer, legal work and completion.

The day-rate arithmetic

Two conventions decide what a contractor can borrow: how many weeks the lender annualises over, and whether it reads the day rate at all.

Step 1. Annualising the day rate

The table annualises an illustrative day rate of £400, 5 days a week, over 46 and over 48 weeks.

Illustrative; the number of weeks is set by each lender. Published criteria checked 29 September 2026 use 46 weeks (for example Halifax, Virgin Money and Aldermore) and 48 weeks (for example Saffron and Principality). Mortgage Lane's usual working basis, from experience of the lenders we use, is 48 weeks.

Step 2. The loan the income supports

The table reads the same contractor two ways at 5 times income: on the day rate annualised over 46 weeks, and as self-employed on an illustrative £40,000 of accounts-based income.

Illustrative arithmetic; 5 times income is an illustrative multiple here and the standard multiple in Mortgage Lane's experience, up to 6 for professionals and specialist products. It is not a product term, and the lender's affordability assessment decides the actual figure. Not an offer of finance.

The difference between £460,000 and £200,000 comes from reading the same person two ways. That gap is the reason contractor-friendly lenders exist, and the reason a contractor's mortgage application starts with choosing the lender before the property.

Step 3. What the lender checks around the number

Around the number, the lender checks your contract history (how long you have been contracting, and whether earlier employment was in the same field); the current contract's remaining term or the renewal pattern; gaps between contracts against its limits; and the structure (limited company, umbrella or PAYE) and the evidence each requires, including an IR35 determination (the client's status determination statement) where the client has issued one, and how the pay is taxed where an engagement inside IR35 is treated as deemed employment. Most of these decide whether the lender will use the annualised figure, and the pay route can also change the figure itself where a lender deducts umbrella or employer costs.

Our experience: on the cases Mortgage Lane arranges, some lenders set no minimum contracting period; where a lender asks for time left on the current contract, around 6 months is the requirement we see most often, although published rules range from about 1 month to 6 months or a renewal; and gaps between contracts are judged lender by lender rather than against one maximum. We annualise over 48 weeks as our usual working basis, and contractor cases usually sit within the lender's standard residential loan-to-value bands. These are the firm's working experience, not market rules, and the lender you apply to applies its own criteria.

Step 4. The umbrella question

Through an umbrella, the payslips show income after the umbrella's margin and employer costs, and lenders differ: some use the payslip income after the umbrella's deductions, some also deduct employer costs before annualising, some use the lower of the contract value and payslip income, and some decline umbrella income altogether. A lender that deducts those costs starts below the gross day rate. Whether a lender reads umbrella payslips under its contractor rules or its employment rules, and how much employment history it wants, depends on the lender. The umbrella payslips, the umbrella's statements and the underlying contract are the evidence it reads.

What decides the case

With the day rate and the contract fixed, you can still choose the lender (its annualisation basis, history and gap rules), the evidence pack and, where there is a choice, the structure. Running the annualisation under each candidate lender's basis before applying shows which lenders fit.
