The self-employed mortgage guide - UK 2026/27

Getting a UK mortgage as a self-employed person is harder than as an employee but well within reach for organised applicants. Most lenders ask for 2-3 years of accounts; some accept 1 year with stronger conditions. The biggest cause of rejection is poor record-keeping or claiming aggressive expenses that depress declared profit. Here is everything UK self-employed mortgage applicants need to know - organised as a Q&A.

7-minute read

For a UK self-employed mortgage in 2026/27: most lenders need 2-3 years of Self Assessment SA302s plus tax year overviews. Some accept 1 year (Halifax, Kensington, certain specialists) with higher rates. Lenders calculate income from net profit (sole trader) or salary + dividends + retained profit (Ltd Co). Affordability is usually 4-4.5x income. Biggest rejection causes: declining-profit trend, aggressive expense claims depressing declared profit, recent late tax filing, and unexplained credit.

The fundamental challenge

UK mortgage lenders are required to assess "affordability" under FCA MCOB rules. For employees, payslips and a P60 prove income. For the self-employed, income is harder to verify - hence longer track records, more documents, and more conservative lending.

The good news: rejection rates for self-employed mortgages are now similar to employed applicants, provided documentation is in order. The pre-2014 era of routine self-employed rejection is gone.

Common questions answered

How many years of accounts do I need?
Most high-street lenders (Nationwide, Halifax, Santander, Barclays, NatWest, HSBC) ask for 2 years of SA302s and tax year overviews. Some accept 3 years (Skipton, Coventry). A few specialists accept 1 year (Halifax via the "1-year accounts" product, Kensington, certain specialist lenders). 1-year mortgages typically come with higher rates - expect 0.3-0.7% premium.
What is an SA302 and how do I get it?
SA302 is HMRC’s tax calculation summary - essentially a one-page document showing your year’s declared income and tax. After filing your Self Assessment, log in to your HMRC Personal Tax Account, go to Self Assessment, and download the SA302 plus the matching "tax year overview" for each year. These are PDF documents that lenders accept directly. SA302s available online go back 4-5 years.
What income figure do lenders use?
For sole traders: net profit after expenses (the "self-employment" page taxable profit figure). For Ltd Co directors: salary plus dividends declared (some lenders also include retained profit if shareholder is sole owner and director). Most lenders average the last 2-3 years. Some take the lower of the most recent or the 2-3 year average - particularly if the trend is declining.
Will aggressive expense claims hurt my mortgage application?
Yes - significantly. Lenders use your declared profit. £10,000 of optional expenses you claimed saved ~£2,800-£4,200 in tax but reduced your assessable income for mortgage purposes by £10,000, which at 4.5x affordability means £45,000 less borrowing capacity. Many self-employed people preparing to apply for a mortgage stop claiming optional expenses for 1-2 years to inflate declared profit.
How is "income" calculated for a limited company director?
Three approaches by lender. Most common: salary + dividends taken in the year. Some lenders: salary + share of net profit (better for owners who retain profits in company). A few specialists: salary + dividends + retained profit in proportion to shareholding. The third approach is most generous for shareholder-directors who don’t extract all profits annually but is offered by relatively few lenders - typically specialist firms or via mortgage brokers.
What deposit do I need?
5-15% in most cases. The 5% deposit market (95% LTV) is accessible for self-employed applicants but with fewer lender options and higher rates. 10% (90% LTV) opens up most mainstream lenders. 15-25% (75-85% LTV) opens up the full market with the best rates. Beyond the standard mortgage market, specialist lenders accept up to 90% LTV for self-employed with 1-year accounts.
Can I use Help to Buy or Shared Ownership as self-employed?
Yes - both schemes accept self-employed applicants on the same documentation basis (2-3 years accounts). Help to Buy Equity Loan closed to new applications in March 2023 but Shared Ownership remains open. Shared Ownership properties typically require 5-10% deposit of YOUR SHARE (not the full property price), making them accessible for self-employed with smaller deposits.
What if I’ve only been self-employed for 1 year?
Halifax, Kensington and certain specialist lenders offer 1-year mortgages. Conditions are stricter: higher deposit typically 15%+; previous employment in the same field is helpful; strong credit record; current contracts or pipeline visible. Expect rate premium of 0.3-0.7% vs 2-year self-employed products. Or wait until you have 2 years - rates improve materially.
Will a year of low profit ruin my application?
Often yes if it’s the most recent year. Many lenders use the LOWER of (most recent year) or (2-3 year average). A bad most-recent year - even if average is strong - can cut borrowing capacity significantly. Mitigations: explain the cause via cover letter from accountant; consider waiting for the next tax year if the recovery is clear; or seek a specialist lender that uses the longer average.
Should I use a mortgage broker?
For self-employed applicants - usually yes. Brokers know which lenders accept which scenarios (1-year accounts, retained profit, declining trend, specialist trades). They often access products not available direct. Fees range from £0 (broker takes commission only) to £500-£1,500. For complex self-employed cases, a fee-paying broker often pays for itself in better rate or lender match.
What about CIS subcontractors?
CIS subcontractors are treated as self-employed by most lenders. Some specialist lenders treat the CIS gross income (before 20% deduction) as the basis for affordability, which can dramatically increase borrowing capacity vs treating the net-of-CIS figure as profit. Worth specifically asking about CIS lending - Halifax, Skipton and several specialists have CIS-friendly products.
How long before applying should I prepare?
Ideally 12-24 months. Things to do in that window: file all Self Assessment returns on time; ensure SA302s available online; avoid aggressive optional expense claims in the year you’ll be assessed on; maintain clean credit (no payment day delays, no excessive credit applications); save the deposit in a clearly traceable account (lenders want to see source); avoid major business changes (new partnership, restructuring) close to application.
