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.
·5 min read
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

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
