Most lenders ask for 2–3 years of accounts, but a genuine number will consider just 1 year, especially with a strong deposit and clean credit. Day-rate contractors have a separate, often more generous route: many lenders will calculate your income directly from your day rate rather than your accounts at all — which can produce a meaningfully higher assessed income than your tax return shows.
Who actually counts as "self-employed" here
For mortgage purposes, you're generally treated as self-employed if you own 20% or more of the business your main income comes from. That's a wider net than it sounds — it covers sole traders, limited company directors taking salary and dividends, partners and LLP members, freelancers with multiple clients, and day-rate contractors on fixed-term engagements. Each of these gets assessed differently, which is the part most generic advice glosses over.
Sole traders and limited company directors
Sole traders are typically assessed on net profit — what's left after business expenses, shown on your SA302 tax calculation and tax year overview from HMRC. Limited company directors are assessed differently depending on the lender: some look purely at salary and dividends drawn, others will also consider retained profit left in the company, which can matter if you deliberately keep drawings low for tax efficiency.
If your first year of trading followed several years of employment in the same field, some lenders will accept just that first year of accounts — treating your prior industry experience as continuity, rather than starting the clock from zero. Worth raising directly with a broker rather than assuming you need to wait for a second year.
Day-rate contractors: a genuinely different route
If you work on a day rate, a growing number of lenders won't use your accounts at all — instead, they annualise your contract income directly: day rate × 5 days a week × roughly 46 weeks (the reduction accounts for holiday, illness, and gaps between contracts). That figure is then treated much like a salary for affordability purposes.
| Day rate | Assessed annual income |
|---|---|
| £400 | ~£92,000 |
| £500 | ~£115,000 |
| £750 | ~£172,500 |
| £1,000 | ~£230,000 |
This often produces a noticeably higher assessed income than a contractor's actual tax return would show, especially for those who draw a modest salary and keep profit in a limited company for tax reasons. It's the reason contractor mortgages can unlock meaningfully more borrowing than the equivalent generic self-employed route.
- Most lenders require at least 12 months of contracting history.
- Your current contract typically needs at least 3–6 months remaining at the point of application.
- You'll usually need the signed contract itself, 3–6 months of bank statements, and proof of ID and deposit — not full accounts.
- Some lenders won't aggregate income across multiple concurrent contracts, so check this specifically if that applies to you.
Day-rate assessment is a specialist route, not a universal one — apply to the wrong lender and you'll simply be assessed as a generic self-employed applicant and asked for accounts you may not have. This is exactly the kind of thing a broker earns their fee on: knowing which lenders actually offer contract-based underwriting before you apply, not after a decline.
Getting your application ready
- Keep your SA302s and tax year overviews for the last 2–3 years easily accessible, even if you expect to use a 1-year or contractor route — having them ready never hurts.
- If you're a limited company director, decide your dividend strategy with your accountant well before applying — a sudden change in drawings right before a mortgage application can look inconsistent to an underwriter.
- Keep business and personal finances cleanly separated in your bank statements — lenders read these closely for self-employed applicants.
- A larger deposit generally makes self-employed applications easier across the board, not just cheaper — it reduces the lender's risk exactly where self-employed income already carries more uncertainty for them.
