Day rate contracting is increasingly common among professionals such as IT consultants, doctors, accountants, engineers, and finance specialists. While the earning potential is often higher than traditional employment, securing a mortgage as a contractor can be more complicated.
Lenders vary significantly in how they assess contractor income. Some take a straightforward approach, annualising your day rate to calculate borrowing power. Others treat you like a self-employed applicant, basing affordability on company accounts or drawings, which can understate true earnings — especially if you work through a limited company and keep income in the business.
For high-value contractors earning £75,000 a year or more (around £500 per day+), choosing the right lender and presenting your application carefully makes all the difference.
How Lenders Assess Contractor Income
The most contractor-friendly lenders will annualise your day rate to calculate income:
- Example: £500 per day × 5 days per week × 46 weeks = £115,000 annualised income.
- Affordability is then based on multiples of this figure, usually between 4.5–5.5× income.
Other lenders are more restrictive, insisting on accounts, payslips, or umbrella pays. This can reduce assessed income by tens of thousands of pounds compared to annualising day rate.

Key Factors That Influence Contractor Mortgage Approval
Not all contractors are assessed equally. Lenders have different appetites for risk, and the following factors typically play a role in how much you can borrow:
Profession
High-value industries such as IT, finance, and medicine are often considered lower risk. Contractors in these fields may benefit from more generous lending multiples compared to those in less stable sectors.
Time in Industry
A proven track record carries weight. Some lenders will consider applicants from day one of their first contract if they have years of experience in the same industry. Others want at least 6–12 months of contracting history before lending.
Length of Current Contract
- Many lenders prefer at least 6 months remaining on your contract.
- Others will accept 3 months, especially with evidence of past renewals.
- Specialist lenders may even accept contracts close to expiry if your CV demonstrates long-term stability.
Employment Gaps
Breaks between contracts are common, but not all lenders treat them the same. Some won’t accept more than 6–12 weeks off per year, while others are more flexible. Long gaps without a strong explanation can reduce borrowing options.
Contract Structure
- Umbrella company contractors may be assessed on payslips rather than gross contract value.
- Multiple contracts can complicate affordability, as some lenders prefer to see a single contract at a time.
IR35 Status
- Outside IR35: Most lenders use your day rate.
- Inside IR35: Some lenders rely on umbrella payslips instead, which can reduce assessed borrowing power.
Finding the right lender makes a significant difference here.
Typical Borrowing Levels for High-Value Contractors
Borrowing is usually calculated at 4.5–5× annualised income, with some lenders stretching to 5.5× for higher earners.
- £500/day (≈ £115,000 annualised) → £517,000–£632,000 borrowing
- £700/day (≈ £161,000 annualised) → £725,000–£885,000 borrowing
This is often far more favourable than relying on limited company accounts, where taxable income may be much lower after expenses.
Deposit and Loan-to-Value (LTV)
Contractors can often access mortgages with deposits as low as 5%, but affordability criteria usually matter more than LTV.
That said:
- 10–15% deposits broaden lender choice and improve rates.
- 25%+ deposits are particularly powerful, as many lenders increase borrowing multiples and reduce stress testing at this level.
Best Practices to Improve Approval Chances
For high-value contractors looking to maximise borrowing, these steps can strengthen your application:
- Apply at the right time – ideally with 6 months left on your contract, or with a renewal already lined up. Shorter contracts can still work, but longer terms inspire more confidence.
- Minimise employment gaps – lenders prefer consistent contracting history. Where possible, avoid breaks longer than 6–12 weeks.
- Keep financial records clean – even if not used directly, tidy company accounts, payslips, and bank statements all help build a picture of stability.
- Highlight professional background – a strong CV in medicine, technology, accountancy, or finance demonstrates reliability.
- Know your lender – some banks don’t understand contractors and won’t assess you fairly. Specialist lenders and those with contractor-specific criteria are usually the best fit.
Final Thoughts
For high-value day rate contractors, securing a mortgage isn’t about whether you can afford it — it’s about finding a lender who recognises your true earning power. With day rates of £500+ and annualised incomes above £75,000, borrowing potential is strong, but approval depends on aligning with the right criteria.
Profession, contract structure, IR35 status, and even gaps between contracts can all affect outcomes. By understanding how lenders view contractors — and which ones are more flexible — you can significantly improve your chances of securing the maximum borrowing available.
