Getting a mortgage when self-employed is not harder than getting one as an employee — it is different. Standard banks assess employed income using payslips and P60s. They assess self-employed income using two-year averages of net profit or salary plus dividends. Specialist lenders do something standard banks cannot: they include retained company profit in the assessable income. That single difference can add 200,000 to 500,000 to the maximum mortgage on identical accounts.
This guide explains how self-employed mortgage assessment works, which approach suits which income structure, and how to choose the right lender for your specific situation across Hampshire and Surrey.
How Banks Assess Self-Employed Income
For sole traders and partnerships: net profit on the SA302 Self Assessment tax return, averaged across the last two years. If net profit was 60,000 in year 1 and 90,000 in year 2, the assessed income is 75,000. The mortgage maximum at 4.5x is 337,500.
For limited company directors: salary plus dividends from the SA302, averaged across two years. Directors who extract minimal salary and dividends (tax-efficient) produce a low bank-assessed income regardless of how profitable their company is. A director on 12,500 salary, 37,500 dividends (total 50,000 extraction) has a bank maximum of 225,000 at 4.5x. Their company might have 200,000 in retained profit — which the bank ignores entirely.
How Specialist Lenders Assess Self-Employed Income
Specialist lenders use different assessment methodologies that produce higher assessable income for most self-employed borrowers.
Retained profit inclusion: On top of salary and dividends, specialist lenders add the retained profit from the company accounts to the assessable income. The same director above with 200,000 retained profit has a specialist-assessed income of 250,000 (50,000 extraction + 200,000 retained). Maximum mortgage at 5x: 1,250,000.
Most recent year only: For growing businesses, specialist lenders can use the most recent year’s income alone rather than a two-year average. A director whose net profit grew from 60,000 to 120,000 has a bank-assessed income of 90,000 but a specialist most-recent-year income of 120,000 — a 135,000 difference in maximum mortgage at 4.5x.
| Income Structure | SA302 Extracted | Retained Profit | Bank Assessment | Specialist Assessment | Extra Mortgage (4.5x) |
|---|---|---|---|---|---|
| Sole trader, 2yr avg | £75,000 | N/A | £75,000 | £90,000 (recent yr) | £67,500 |
| Ltd director, S+D | £50,000 | £0 | £50,000 | £50,000 | £0 |
| Ltd director + retained | £50,000 | £120,000 | £50,000 | £170,000 | £540,000 |
| Ltd director + large retained | £50,000 | £250,000 | £50,000 | £300,000 | £1,125,000 |
What Documentation You Need
For sole traders and partnerships: last two years of SA302 Self Assessment tax calculations (downloadable from HMRC online) and corresponding Tax Year Overview documents. Some lenders also require the full accounts if prepared by an accountant, though many accept SA302 alone.
For limited company directors: last two years of company accounts (prepared by an accountant, ideally filed at Companies House). Last two years of SA302 for the director’s personal tax. If applying for most-recent-year assessment: the most recent year’s accounts and SA302, plus prior employed history confirming the same discipline if using one-year.
One year of accounts: some specialist lenders accept one year where the applicant has directly relevant prior employed experience in the same field. A software engineer who was employed for 10 years and incorporated their business 14 months ago can make a strong case for one-year assessment at specialist lenders.
Common Mistakes Self-Employed Buyers Make
Applying to a high street bank first. The bank declines or offers far less than the specialist market. The declined application registers as a hard credit search. Multiple declined applications compound the problem. Start with a specialist adviser and a soft search that confirms the right lender before any application.
Minimising income extraction for tax efficiency. Tax-efficient extraction is the right strategy for running your business. It creates a lower bank-assessed income for mortgage purposes. The solution is retained profit assessment at specialist lenders, not paying more dividends to look better on a bank application.
Not having accounts ready. Filed and signed accounts are required before application. Draft accounts, unsubmitted SA302s and management accounts are not accepted. If your accounts are not yet filed for the most recent year, the assessment uses the year before. Timing a mortgage application to coincide with freshly filed accounts can meaningfully improve the assessed income.
Self-Employed Mortgages by Location
The self-employed mortgage challenge is identical regardless of where you are buying in Hampshire or Surrey. The lender selection process — identifying which specialist lender offers the best income methodology for your specific structure — applies equally to a purchase in Basingstoke, Guildford or Winchester. What differs by location is the price range and therefore the absolute pound value of the income assessment gap. In Winchester’s 580,000 to 900,000 family home market, the difference between standard and specialist assessment can determine access to the market entirely. In Basingstoke’s 310,000 to 480,000 market, it determines which end of the market is reachable.

📞 01252 111 000The One-Year Accounts Route
For self-employed buyers who incorporated their business less than 2 years ago, or who have had a significant income step-change within the last 12 months, the one-year accounts route is often the fastest path to the right mortgage. Specialist lenders who accept one year of accounts typically require: the most recent 12 months of company accounts prepared by an accountant; an SA302 for the same period; and evidence of directly relevant prior employment in the same discipline. A systems architect who was employed for 12 years, set up a limited company 15 months ago and has 130,000 in company profit has a strong one-year case at the right specialist lender.
How We Confirm the Right Lender
Before any application, we run a soft search that has no impact on your credit score. We identify the income assessment methodology that produces the best outcome for your specific structure — retained profit, most recent year, one-year accounts, or standard two-year average. We confirm lender acceptability for the target property type (period and rural Hampshire and Surrey stock requires specific survey competence alongside income competence). Only once both the income and the property are confirmed do we submit the application. The application is submitted once, to the right lender. No declined applications. No multiple hard searches.
