Your day rate is the application. Not three years of accounts.
High-street lenders treat a £600-a-day developer like a struggling small business and ask for years of tax returns. Contract-based lenders read the contract in your hand — and lend on the rate it pays.
Built for the contract, not the back-catalogue
Contract-based underwriting assesses your current contract rate instead of historic accounts or SA302s. For an IT contractor — high day rate, cyclical projects, often newly independent — it is the difference between a real offer and a polite decline.
Most IT contractors earn well but look awkward on paper to a retail bank. You may have left a permanent role months ago, switched from a limited company to an umbrella, or have a year of accounts that doesn’t reflect your current rate. The high-street algorithm reads all of that as risk. A contractor-friendly lender reads your contract, your rate and your track record in the sector — and prices the mortgage off your real earning power.
From day rate to borrowing
What a five-day contract supports
£115,000 × 4.5 = £517,500 indicative borrowing
The 46-week year leaves a six-week buffer for holidays and gaps between contracts — so the figure is sustainable, not optimistic.
Why do IT contractors fit this model so well?
- High, verifiable rates. A signed contract states your rate clearly — exactly what contract-based lenders want to see.
- Strong sector demand. Lenders view established tech skills as a low risk of long-term unemployment.
- Frequent renewals. A history of back-to-back contracts demonstrates continuity even without permanent employment.
- Financial literacy. Many IT contractors want fixed rates to hedge against volatility — a conversation specialist advisers are ready for.
What documents do you need?
- Your current signed contract, showing rate, term and parties.
- An up-to-date CV evidencing your contracting and employment history.
- Three to six months of personal bank statements.
- Proof of deposit, identity and address.
- If through a limited company, recent accounts may strengthen — but are not always required.

IT contractor mortgages, answered
Can I get a mortgage in my first IT contract?+
Often yes. Contract-based lenders assess your current contract and professional background rather than a long trading history. With a solid day rate, a relevant CV and a clean record, some lenders will lend from the first day of a contract — even if you only went independent recently.
How is my income worked out from a day rate?+
Your rate is annualised as day rate × days per week × 46 weeks, then multiplied by around 4.5. A £500 day rate becomes roughly £115,000 a year and supports about £517,500 of borrowing, before deposit and affordability checks.
Do gaps between contracts hurt my application?+
Short, normal gaps are expected and built into the 46-week calculation. Long or unexplained gaps can narrow the lender pool, but rarely rule you out. Presenting your contract history clearly is part of how a broker keeps the strongest lenders in play.
Does my IR35 status affect my mortgage?+
IR35 changes how you are taxed, not whether you can borrow. Outside-IR35 contractors are usually assessed on their day rate; inside-IR35 or umbrella contractors are assessed on gross contract value or payslips. Either way, specialist lenders have a route.
What deposit do I need as an IT contractor?+
The same as any borrower — typically from 5% to 10% upwards, with better rates at 15% and above. Your contractor status affects how income is assessed, not the deposit thresholds themselves.
