Contractor mortgages
Explore how lenders assess contract income, including day rates, contract history and gaps between roles. The guide sets out the evidence borrowers may need.
What is a contractor mortgage?
A contractor mortgage is a UK residential mortgage for borrowers who work on fixed-term contracts rather than in permanent employment. Many lenders with contractor criteria annualise the contractor's day rate into a notional yearly income, rather than relying only on payslips or company accounts.
Who qualifies as a contractor?
You are usually treated as a contractor if you:
- work on fixed-term contracts with a set end date rather than in a permanent role
- are paid through your own limited company, an umbrella company or agency PAYE
- work in a sector such as IT, engineering, construction, healthcare, finance or consulting
For a lender, the structure and continuity of your contracts matter more than the employment status label.
How contractor mortgage affordability is calculated
Many lenders with contractor criteria use a day-rate income model:
Day rate × days worked a week × the lender's number of weeks, commonly 46 or 48
For example, £500 × 5 × 46 = £115,000 of notional income (illustrative).
For limited company contractors this can give a higher borrowing figure than an assessment based on salary and dividends.

Day rate assessment vs company accounts
Lenders read a limited company contractor's income in one of two ways, and the lender's rules decide which applies.
Day rate assessment
- Uses the annualised day rate, with no reliance on salary or dividends
- Usually ignores retained profits
- Can give a higher figure, although some lenders' contractor routes set a minimum day rate or income
- Available from some high street and specialist lenders
An accounts-based assessment, by contrast:
- Uses salary, dividends or net profit
- Applies where a lender has no contractor route, or where the contractor does not meet its contractor rules
- Often gives a lower figure
Which method applies is set by the lender's rules, so correct lender selection decides it.
Contract requirements
Contractor-friendly lenders may ask for:
- A minimum time left on the current contract, commonly one to six months, or evidence of renewal
- A contracting history of 12 to 24 months, although some lenders accept less, or experience in the same line of work instead
- Gaps between contracts within the lender's limits: some set a maximum, such as 6 weeks, and others judge gaps case by case
- A CV showing continuity in the same industry
- Recent bank statements showing the income received
A renewal letter or a signed extension helps show the income is likely to continue.
Inside IR35 vs outside IR35
- Outside IR35: usually a day-rate assessment under the lender's contractor rules
- Inside IR35: some lenders say they accept contractors inside IR35, and where the pay runs through an umbrella company, the lender's umbrella rules apply
Why the lender pool can be narrower
Where inside-IR35 pay runs through an umbrella company, the lender pool can be narrower, because some lenders do not accept umbrella income and others deduct umbrella or employer costs before annualising. Where a lender deducts those costs, the income it uses is lower, which can reduce borrowing, so the pay route that follows from your IR35 status affects which lenders' rules fit as well as how much you can borrow.
Deposit requirements and loan-to-value (LTV)
- Residential contractor mortgages: LTV depends on the lender and product, and some lenders publish contractor maximum LTVs of 95%
- In Mortgage Lane's experience, contractor cases usually sit within the lender's standard residential loan-to-value bands
- First-time buyer contractors can be considered, although lenders differ on the contracting history they need
- Buy-to-let contractor mortgages: LTV depends on the lender and product
Credit profile considerations
- With clean credit, both high street and specialist lenders may be open to you
- Minor adverse credit may still be acceptable to some lenders
- Recent defaults or CCJs restrict the options but do not automatically rule out lending
FCA regulation and Consumer Duty
Contractor mortgages on a main residence are regulated by the FCA. This means:
- A full affordability assessment by the lender, and suitable advice
- Advice based on the evidence of your income and circumstances
- The Consumer Duty applies whatever your income structure
Non-standard income does not reduce your regulatory protection.
Common reasons contractor applications fail
- The lender uses salary and dividends instead of the day rate
- The contract has too little time left to run
- The IR35 position is misread
- The case relies too heavily on umbrella payslips
- The application goes to a lender without contractor criteria
A decline for one of these reasons reflects that lender's criteria, so another lender's rules may fit.
Why contractor mortgage expertise matters
Contractor lending is lender specific. The outcome depends on:
- The income method the lender uses
- How it reads the contract
- Continuity in your sector
- The lender's appetite at the time of application
Applying to a lender whose rules do not fit can mean a lower income figure or an avoidable decline.

Frequently asked questions
Can an inside-IR35 IT contractor get a mortgage?
It can be possible. IR35 is a tax status rather than a lending rule, and some lenders say in their criteria that they accept contractors inside IR35: Virgin Money, for example, accepts contractors operating inside IR35 and those paid through a PAYE umbrella company (published criteria checked 29 September 2026). What changes the figure is how you are paid. Virgin Money deducts employer National Insurance, Apprenticeship Levy and payroll costs from gross pay before annualising, and Halifax uses the lower of the gross contract value and your payslip or bank statement income. Some lenders, such as Bath, do not consider umbrella income at all. These examples are individual lenders' published rules, which can change; they do not show which lenders Mortgage Lane uses or decide any application.
What is a contractor mortgage?
A contractor mortgage is a residential mortgage assessed on a contractor's contract income, usually the day rate annualised over a working year, or umbrella or fixed-term payslips, rather than on two or three years of self-employed accounts or a permanent salary. The mortgage itself is a standard regulated loan, and lenders differ in how they read the income.
Can an IT contractor remortgage?
An IT contractor can remortgage where the new lender's rules are met. A remortgage to a new lender is assessed like a purchase: the lender applies its contractor rules to your current contract, history and pay route. Staying with your current lender on a new product (a product transfer) may not need a new income assessment where you borrow no more (other than fees) and nothing material to affordability changes: FCA rules let the lender choose not to reassess affordability in that case, but it is the lender's choice and product availability varies.
How do contractor mortgages work?
The lender treats the contract as the evidence of income. It annualises the day rate over a set number of working weeks, or assesses umbrella and fixed-term payslips as employed income, and checks the contracting history, the contract's remaining term and any gaps. The income it arrives at then goes through its standard affordability assessment.
How much can an IT contractor borrow?
It depends on the lender's affordability assessment and on how it reads your income. Illustratively, on £550 a day annualised over 46 weeks (£126,500), 5 times income, the standard multiple in Mortgage Lane's experience, could support £632,500, and over 48 weeks (£132,000) it could support £660,000. The same contractor read as self-employed on £45,000 of accounts-based income could support £225,000 on the same multiple. These are illustrative figures, not typical lending or an offer: the lender's number of weeks, its treatment of umbrella costs and its affordability checks decide the actual amount.
