Why self-employed mortgages are different
Lenders can't see a self-employed applicant's income on a payslip, so they assess it from accounts and tax records — and they don't all do it the same way. The best self-employed mortgage is the one whose income calculation suits how your business reports profit. Matched to the right lender you access the same high-street rates as an employee; get it wrong and you'll be needlessly declined.
1. Mortgages based on 2 years' accounts (the mainstream route)
Most lenders want two years of accounts or SA302 tax calculations and average your income across them (or use the most recent year if lower). Best for established sole traders and partners with stable or rising profits — the widest choice and best rates.
Pros: mainstream rates, broad choice. Cons: needs a two-year track record; a weak latest year drags the average.
2. Mortgages for 1 year of accounts
A smaller group of lenders consider just one year of accounts. Best for those recently self-employed with a strong first year, ideally in the same line of work they were previously employed in. Expect a narrower choice and extra evidence of ongoing work.
3. Limited company director mortgages
If you trade through a limited company, assessment matters hugely. Many lenders count only salary plus dividends — penalising directors who retain profit for tax efficiency. The best lenders assess salary plus your share of net (or retained) company profit, often letting you borrow far more. See our best mortgages for company directors guide.
4. Contractor mortgages
On day-rate contracts, some lenders base income on an annualised day rate rather than accounts — usually far more generous. Best for IT, engineering, medical and other professional contractors. See our best mortgages for contractors guide.
5. Specialist and complex-income mortgages
For multiple income streams, fluctuating profits, or a recent business change, specialist lenders take a manual, common-sense view. Rates are slightly higher but they say yes where high-street computers say no.
Documents you'll typically need
- Two years of certified accounts or SA302s plus tax year overviews
- Three to six months of business and personal bank statements
- Proof of ongoing work (contracts, a healthy order book)
- Details of any director's loan or retained profit if you trade via a company

Frequently asked questions
How many years of accounts do I need?
Most lenders want two years, but some accept one. More history and stable profits mean wider choice and better rates.
Can I get a mortgage in my first year of self-employment?
Yes, with a smaller pool of lenders — especially with a strong first year in the same field you previously worked in as an employee.
Do self-employed people pay higher mortgage rates?
Not if matched to a mainstream lender that accepts your accounts. You only pay more if your case needs a specialist lender.
I'm a director — why will one lender lend far more than another?
Because some count only salary and dividends, while others add your share of retained company profit, which can increase borrowing substantially.
Should I reduce my tax bill or maximise my mortgage?
There's a trade-off: minimising declared profit cuts tax but also cuts assessable income. Plan two to three years ahead, ideally with an accountant and broker together.
