The gap between what high street banks see and what contractor underwriters use.
£800 × 5 days × 46 billable weeks = £184,000 annual income. This is the industry-standard formula used by contractor-specialist mortgage lenders across the UK.
UK specialist lenders apply a multiple of 4.5× to 5.5× to the income baseline. This produces a borrowing range of £828,000 to £1,012,000 on your £800 rate.
A high street bank using your director salary of £12,570 × 4.5× offers just £50,000. That is £778,000 less than the specialist lower bound — for the same contractor.
Outside IR35 via your own Ltd company is the strongest position. Specialist lenders use the full £800/day formula and your £184,000 income baseline. SA302 forms support the application but are not the primary assessment. Maximum borrowing up to £1,012,000.
Inside IR35 via umbrella: your payslip shows PAYE income after deductions. Most specialist lenders now accept the gross contract rate (£800/day) for assessment rather than the net payslip figure. Borrowing capacity is broadly similar but depends on the lender's specific umbrella policy.

Property price benchmarks are approximate market averages for 2026 and will vary significantly by specific location, property type, and market conditions. Your purchase ceiling depends on your actual borrowing offer, deposit size, and solicitor/stamp duty costs. Always obtain a formal mortgage offer before exchanging contracts.
On a £800 day rate, your annual income baseline using the contractor formula (£800 × 5 days × 46 weeks) is £184,000. A contractor-specialist lender applying income multiples of 4.5× to 5.5× would offer between £828,000 and £1,012,000. A high street bank assessing a director salary of £12,570 would typically offer around £50,000.
Most high street lenders assess Ltd company directors on their PAYE salary, not their actual earning power. A contractor drawing £12,570 (the personal allowance, to minimise income tax) is assessed as a low earner. Contractor-specialist lenders understand this structure and base affordability on the day rate formula instead, which accurately reflects your earning capacity.
Outside IR35: specialist lenders use the full £800/day formula as your income baseline, giving you the full £828,000 to £1,012,000 range. Inside IR35 via umbrella: lenders may use the gross contract rate or your PAYE payslips. Most specialist lenders now accommodate both, though the strongest position for maximum borrowing is typically outside IR35 through your own Ltd company.
For a £800/day contract: your current contract (at least 3–6 months remaining), last 3–6 months of business bank statements, last 2 years of SA302 forms, and Ltd company accounts if outside IR35. Some lenders accept first-time contractors with a strong current contract.
The industry standard is 46 weeks. This accounts for approximately 6 weeks of annual leave and bank holidays during which contractors do not bill. Most specialist lenders use 46 to 48 weeks. The calculator defaults to 46, which is the most conservative and most widely accepted figure for underwriting purposes.
Yes, in a few ways. Some specialist lenders go up to 5.5× income or higher for high earners with a strong track record. Adding a second applicant's income increases the borrowing ceiling. Some lenders will also consider dividend income on top of the day rate formula. A specialist contractor mortgage broker can identify which lenders will give you the maximum figure for your specific situation.
Most contractor-specialist lenders in the UK offer up to 85–90% loan-to-value (LTV), meaning a 10–15% deposit is typically the minimum. On your maximum specialist borrowing of £1,012,000, a 10% deposit would allow you to purchase a property up to £1,124,000. Some lenders require 20–25% for borrowers with shorter contract histories, but contractors with a strong track record and a current contract often access the same LTV ranges as employed borrowers. A larger deposit also lowers the interest rate tier.
With a specialist contractor mortgage broker, the typical timeline is 4–8 weeks from initial enquiry to mortgage offer. Key stages: initial assessment and decision in principle (1–2 weeks), full application and document submission (1–2 weeks), lender underwriting and valuation (2–4 weeks). Having your current contract, 3–6 months of business bank statements, and most recent SA302s ready significantly accelerates the process. Some lenders offer fast-track underwriting for contractors — ask your broker specifically about turnaround times.
