Can I get a mortgage as a day-rate IT contractor?

Yes — most UK high-street lenders in 2026 assess day-rate contractors on day rate × 5 × 46–48 weeks (an annualised gross income), with Halifax, Clydesdale, Kensington, Santander and Virgin Money all offering contractor-specific policies that don’t require two years of accounts — typically needing 12 months’ trading plus 6 months left on the current contract.

How does the day-rate calculation work?

Contractor mortgage underwriting ignores self-assessment figures entirely and treats your day rate as if it were a salary. The standard formula is:

Day rate × 5 (working days per week) × 46 or 48 (working weeks per year)

Most lenders settle on 46 weeks — that’s 52 minus 2 weeks holiday, bank holidays, and a buffer for gaps between contracts. A minority (Halifax for strong cases, Kensington on manual underwrite) will use 48 weeks.

Worked example — a £450 per day contractor:

Halifax @ 46 weeks: £450 × 5 × 46 = £103,500 gross
Kensington @ 48 weeks: £450 × 5 × 48 = £108,000 gross
Applied at 4.5× LTI: loan ceiling ~£465,750–£486,000

For the same applicant, self-assessment returns might show £70,000–£80,000 of personal income (after company expenses, corporation tax and dividend drawdown) — but contractor underwriting ignores that and takes the day-rate approach, which almost always produces a higher affordable loan.

A contractor reviewing their day-rate contract alongside a mortgage application — Contractor-specific underwriting annualises your day rate instead of squeezing your tax return.

What do you actually need to provide?

The standard contractor document pack in 2026:

Current contract, showing day rate, start date and end date.
6+ months remaining on current contract, or proof of recent renewal.
12 months minimum trading history as a contractor (some lenders accept continuous PAYE employment in the same field immediately before).
3 months business bank statements (if trading via Ltd).
3 months personal bank statements.
CV showing the career arc.

What you usually don’t need: SA302s, company accounts or P60s. Contractor-specific criteria are designed to bypass those entirely.

Which lenders actually do this?

Lender	Policy notes	Typical max LTV
Halifax	12 months contracting or matching employment; 46-week basis	85–90%
Clydesdale / Virgin Money	6 months on current contract + 6 months elsewhere	85–90%
Kensington	Manual underwriting; up to 48 weeks for strong applicants	85%
Santander	Sector-flexible; 12 months’ trading required	85–90%
Barclays	12 months trading; 4.49×–4.75× LTI	85%
HSBC	Will treat via PAYE umbrella income only	85%

These are the lenders best-known to brokers as contractor-friendly; criteria shift quarterly.

Ltd-co contractor, umbrella, or sole trader?

It rarely matters to the day-rate calculation — what matters is the evidence you can show. But there are nuances:

Ltd-co contractors. Standard route, lender uses day-rate × 5 × 46. IR35 status is asked about but rarely decisive for “outside IR35” contracts.
Umbrella / PAYE. If you’re inside IR35 via an umbrella, you’ll be assessed as employed using your PAYE payslips from the umbrella — same as any other employee.
Sole trader. Covered by the 1-year self-employed route if contractor-specific criteria don’t apply. Sole-trader contractors are less common in IT post-IR35.

Our affordability calculator has a contractor mode that uses the day-rate × 5 × 46 basis.

What underwriters check on the contract

Day rate consistency. A jump from £300 to £500 in the latest contract will be averaged across recent months rather than taken at face value.
Gaps between contracts. 2–4 week gaps are normal. 8+ weeks out of contract in the last 12 months can trigger questions.
End date. Less than 3 months remaining and no renewal can be a decline; some lenders ask for a client letter confirming intent to renew.
Inside/outside IR35. Doesn’t change the math for mortgage purposes but affects which route (contractor vs umbrella) your application takes.

The misconception that costs contractors money

Contractors who apply via standard self-employed criteria and hand over their SA302s almost always get a smaller loan than they’d qualify for under contractor-specific underwriting. The fix: tell the lender (or broker) upfront that you’re contracting, not that you’re “self-employed.” The product you want is explicitly a contractor mortgage, not a sole trader mortgage — different criteria, different maths, usually £50k–£200k more borrowing on the same day rate.
