A guide to self-employed mortgages
Self-employed borrowers can access the same mortgage products as employed applicants — but proving your income works differently. This guide explains what lenders look for, what documents you’ll need, and how to put yourself in the strongest position.

What counts as self-employed for mortgage purposes?
Lenders generally classify you as self-employed if you own more than 20–25% of a business that provides your main income. This includes sole traders, partners in a business, limited company directors, and contractors working through their own company.
The way lenders assess your income varies depending on your business structure, which is why it’s important to understand how your specific set-up is viewed.
How do lenders assess self-employed income?
- Income based on net profit (turnover minus expenses)
- Most lenders average the last 2–3 years
- Some use the latest year if it’s higher — useful if your business is growing
How many years’ accounts do you need?
1 year
Minimum (some lenders)

Gives a fuller picture and may unlock better rates
If you’ve been trading for less than two years, don’t assume you can’t get a mortgage. Some specialist lenders will consider one year’s accounts, particularly if you have a strong background in the same industry, a qualified accountant’s reference, or a healthy deposit.
What documents will you need?
- Issued by HMRC after you file your Self Assessment
- Shows your total income and tax paid for each year
- Download from your HMRC online account or request by post
Do self-employed borrowers need a bigger deposit?
Not necessarily. Self-employed applicants can access the same deposit levels as employed borrowers — from 5% upwards with many lenders. The key difference is that your income evidence needs to be watertight.
That said, a larger deposit does help if your income fluctuates or you have fewer years of accounts. A 10–15% deposit gives you access to more lenders and better rates than 5%, and at 25% you’ll unlock the most competitive products in the market.
Common challenges and how to overcome them
- Tax-efficient accounting can reduce the income lenders see
- Consider your mortgage plans when discussing tax returns with your accountant
- Some lenders look at gross profit or retained earnings, not just declared income
- If income has dropped year-on-year, some lenders use the lower year
- Others will average or use the latest year if higher
- A broker matches you with the lender whose method gives the best result
- Under 2 years’ accounts limits options but doesn’t rule you out
- Previous industry experience can strengthen your case
- A larger deposit helps compensate for shorter trading history
The self-employed mortgage application process
Applying for a mortgage when self-employed follows the same broad steps as any mortgage, with extra emphasis on income verification.
Organise your documents
Gather your SA302s, tax year overviews, accounts, bank statements, and ID. If any are missing, order them from HMRC or your accountant well in advance.
Speak to a specialist broker
A broker experienced with self-employed income will assess which lenders view your income most favourably and how much you’re likely to borrow.
Get a Decision in Principle
The lender runs a soft credit search and preliminary income check. This gives you confidence about your budget before house hunting.
Find your property and make an offer
With your DIP in hand, you can make offers knowing what you can afford. Sellers and agents take DIP-backed offers more seriously.
Full application and underwriting
Submit your full documentation. The lender’s underwriter reviews your income, accounts, and credit history in detail. This is where self-employed applications take a little longer.
Valuation, legal work, and completion
Once approved, the lender values the property, your solicitor handles the legal work, and you complete the purchase. Your broker manages the process and chases any hold-ups.
Why use a broker for a self-employed mortgage?
Self-employed mortgages are where brokers add the most value. The difference between lenders’ income assessments can mean tens of thousands of pounds in borrowing capacity. A broker knows which lender will assess your income most generously and which criteria you need to meet.
