Self-Employment Guides UK — Tax, Business Setup, and Running Your Own BusinessSelf-Employed Mortgage — How Much Can You Borrow?
How mortgages work for self-employed people in the UK. What lenders look for, how much you can borrow, required documents, and tips to improve your chances.
Getting a mortgage when self-employed is absolutely possible, but the process requires more preparation than it does for employees. This guide covers what lenders need, how your income is assessed, and how to put together the strongest application.
Can Self-Employed People Get Mortgages?
Yes. Self-employed borrowers can access the same mortgage deals as employed applicants. Lenders have no separate “self-employed mortgage products” — the rates and deals are the same. What differs is the evidence you need to provide and how your income is calculated.
How Lenders Assess Your Income
Sole Traders and Partnerships
| What lenders look at | How they calculate it |
|---|
| SA302 tax calculations | Usually the last 2–3 years |
| Net profit | Your taxable profit after allowable expenses |
| Average or latest year | Some take the average, some use the latest year, some use the lower figure |
| Trend | Rising income is viewed favourably |
Limited Company Directors
| What lenders look at | How they calculate it |
|---|
| Salary | Your PAYE salary from the company |
| Dividends | Dividends paid to you |
| Combined income | Salary + dividends is the standard calculation |
| Some lenders use net profit | Your share of the company’s net profit (before dividends and tax) — often gives a higher figure |
| Retained profits | Some specialist lenders consider profits retained in the company |
Using a lender that assesses income based on company net profit rather than salary plus dividends can significantly increase your borrowing power.
Contractors (Day Rate)
| What lenders look at | How they calculate it |
|---|
| Day rate | Your contracted daily rate |
| Annualised income | Day rate × 5 days × 46–48 weeks |
| Contract evidence | Current contract plus history of renewals |
| Some treat as employed | A few lenders annualise your day rate without requiring 2 years of accounts |
How Much Can You Borrow?
| Income | 4× multiple | 4.5× multiple | 5× multiple |
|---|
| £30,000 | £120,000 | £135,000 | £150,000 |
| £40,000 | £160,000 | £180,000 | £200,000 |
| £50,000 | £200,000 | £225,000 | £250,000 |
| £60,000 | £240,000 | £270,000 | £300,000 |
| £80,000 | £320,000 | £360,000 | £400,000 |
| £100,000 | £400,000 | £450,000 | £500,000 |
Most mainstream lenders offer 4 to 4.5 times income. A mortgage broker can find lenders offering higher multiples for strong applications.
What Documents Do You Need?
Essential Documents
| Document | Where to get it |
|---|
| SA302 tax calculations (2–3 years) | HMRC online (Personal Tax Account) or your accountant |
| Tax year overviews (2–3 years) | HMRC online |
| Accounts (2–3 years) | Your accountant (certified accounts preferred) |
| Bank statements (3–6 months) | Your bank (personal and business) |
| Proof of ID | Passport or driving licence |
| Proof of address | Utility bill or council tax bill |
| Mortgage statement (if remortgaging) | Current lender |
Additional Documents (If Applicable)
| Situation | Document needed |
|---|
| Limited company director | Company accounts, CT600 corporation tax return |
| Contractor | Current contract and contract history |
| Recently self-employed (1 year) | Full year’s accounts plus a strong projection from your accountant |
| Mixed income (employed + self-employed) | Both employed payslips and self-employed accounts |
How to Get SA302s
| Method | Steps |
|---|
| Online | Log into your HMRC Personal Tax Account → Self Assessment → View tax years → Print SA302 and tax overview |
| By post | Call HMRC on 0300 200 3310 and request them — takes 1–2 weeks |
| Through your accountant | If they filed your return, they can print them from their agent portal |
Improving Your Chances
Before You Apply
| Action | Why it helps |
|---|
| Use an accountant | Professionally prepared accounts carry more weight with lenders |
| Maximise your declared income | Claiming aggressive expenses reduces your profit and therefore your borrowing capacity |
| Build a deposit | 15–20% deposit gives you access to better rates |
| Improve your credit score | Check and fix errors 3–6 months before applying |
| Reduce debts | Pay down credit cards and loans — they reduce your affordability |
| File your tax returns on time | Late filing is a red flag for lenders |
| Keep clean bank statements | Avoid gambling transactions, unpaid direct debits, and regular overdraft use |
The Expenses vs Borrowing Trade-Off
There is a tension between minimising tax and maximising mortgage borrowing:
| Approach | Tax effect | Mortgage effect |
|---|
| Claim all possible expenses | Lower tax bill | Lower declared income → smaller mortgage |
| Claim fewer expenses | Higher tax bill | Higher declared income → larger mortgage |
In the years before applying for a mortgage, consider whether a slightly higher tax bill is worth the increased borrowing power. Discuss this with your accountant.
Common Challenges and Solutions
| Challenge | Solution |
|---|
| Only 1 year of accounts | Some lenders accept 1 year — use a broker to find them |
| Declining income | Explain why (e.g. COVID, investment in the business). Some lenders use the latest year only |
| Low declared profit | Consider lenders that use company net profit for directors |
| Complex income (multiple sources) | A broker can find lenders comfortable with complex income |
| Recent change to limited company | Some lenders will use sole trader history plus company accounts |
| Bad credit | Specialist lenders exist — expect higher rates and larger deposit requirements |
Using a Mortgage Broker
A mortgage broker is particularly valuable for self-employed applicants because:
| Reason | Why it matters |
|---|
| They know which lenders are self-employed friendly | Not all lenders assess income the same way |
| They can match income calculation methods to your situation | Salary + dividends vs net profit can make a massive difference |
| They handle the paperwork | Self-employed applications have more documentation |
| They can present your income in the best light | Explaining gaps, changes, or unusual patterns |
| They access exclusive deals | Some lender deals are only available through brokers |
