Getting a self-employed mortgage is entirely achievable, yet many business owners assume the door is closed to them. The truth is more encouraging. Lenders are used to lending to self-employed applicants; they simply assess your income differently from someone on a fixed salary. Understand how that assessment works, prepare the right evidence, and your position can be every bit as strong as an employed borrower's.
At Wisely, self-employed borrowers are a core specialism. We know these readers often feel underserved by the high street, where a rigid tick-box process struggles to make sense of real business income. This guide explains how self-employed mortgages work, what counts as self-employed, the paperwork you will need, and the practical steps that improve your chances.
What counts as self-employed?
Lenders generally treat you as self-employed if you own 20% or more of a business (some use 25%), or if you work for yourself rather than drawing a salary as an ordinary employee. In practice, that covers several structures:
- Sole traders who report profits through Self Assessment.
- Partners in a partnership, taking a share of profits.
- Limited company directors who own a meaningful shareholding.
- Contractors and freelancers working on day rates or short contracts.
Each of these earns and reports income in a different way, which is why lenders ask for different evidence depending on your setup. If you are unsure which category applies to you, a whole-of-market broker can quickly place you.
How lenders assess self-employed income
There is no single "self-employed mortgage" product. You apply for the same mortgages as everyone else, but the affordability assessment focuses on the income your business genuinely generates.
Sole traders and partners are usually assessed on net profit — the figure after allowable expenses but before tax — as reported to HMRC. Most lenders take an average of the last two or three years, though some will work from the latest year if that is what your accounts show.
Limited company directors are more nuanced. Many lenders use your salary plus dividends drawn from the company. A smaller but valuable group of lenders will instead consider your salary plus your share of retained (net) profit, which can significantly increase the income figure if you leave money in the business for tax efficiency. Choosing a lender that takes the right approach for your accounts can be the difference between a modest loan and the one you actually need.
Because lenders vary so much, two of them can look at the same accounts and offer very different amounts. That variation is precisely why advice matters.
The evidence you will need
Preparation is the single biggest factor in a smooth application. Most lenders will ask for a combination of the following.
Accounts
Typically two to three years of finalised accounts, prepared by a qualified or certified accountant. Some lenders will consider one year's accounts if the picture is otherwise strong — we cover that in our dedicated guide below.
SA302 and tax year overviews
For sole traders and many directors, lenders rely on your SA302 tax calculation together with the corresponding tax year overview from HMRC. The SA302 shows the income you declared; the tax year overview confirms the tax due and paid, proving the two match. You can download both from your HMRC online account or ask your accountant.
Business bank statements
Usually the last three to six months, to show trading activity and cash flow. Personal statements may also be requested.
Proof of deposit and ID
Standard documents apply: evidence of your deposit funds, photo ID and proof of address.
Keeping these organised and up to date before you apply avoids delays and presents your business in its best light.
Deposits for self-employed borrowers
There is a persistent myth that self-employed applicants need a larger deposit. In reality, the minimum deposit is the same — typically 5% to 10% of the property value, meaning a 90% or 95% loan-to-value mortgage may be possible.
That said, a larger deposit does help. Bringing 15% or 25% to the table opens up more lenders, unlocks lower interest rates, and gives underwriters more comfort where your income fluctuates year to year. If you have the flexibility, a bigger deposit is one of the most reliable ways to strengthen a self-employed application.
How to improve your chances
The good news is that much of your success is within your control. Consider the following:
- Keep clean, up-to-date accounts. Finalised figures from a recognised accountant carry far more weight than draft numbers.
- Register on the electoral roll at your current address and keep your credit file tidy.
- Avoid large, unexplained outgoings in the months before applying — underwriters scrutinise bank statements.
- Think carefully about tax planning. Aggressively minimising your declared profit reduces your tax bill but also reduces the income a lender can use. There is a balance to strike between tax efficiency and mortgage affordability.
- Show a stable or rising trend. Lenders are reassured by consistent or growing income. If your latest year dipped, be ready to explain why.
- Reduce short-term debt where you can, as monthly commitments lower your affordability.
Small, deliberate steps in the year before you apply can meaningfully increase what you are able to borrow.
Why a whole-of-market broker matters
Self-employed lending is where broker advice earns its keep. High-street lenders apply fixed criteria; a whole-of-market broker knows which of the 120+ lenders will treat your particular income structure most favourably.
At Wisely we place your accounts with the lender most likely to say yes on sensible terms, present your income in the way that lender wants to see it, and manage the application through to completion with a single named adviser. We charge a clear, capped fee for mortgage advice, agreed upfront — paid advice is a deliberate part of how we work, because it aligns us fully with getting you the right outcome rather than the quickest one (and our protection advice is free).
We are independent, FCA-regulated and whole-of-market, based in Southampton and serving clients across Hampshire and the UK. To date we have arranged more than £430m of lending for over 2,800 clients, with a 5/5 Google rating.

Frequently asked questions
Can I get a mortgage if I am self-employed?
Yes. Self-employed applicants can access the same mortgages as employed borrowers. Lenders simply assess your income from your accounts, SA302s and tax year overviews rather than payslips. With the right evidence and lender, your options may be just as strong.
How many years of accounts do I need?
Most lenders prefer two to three years of finalised accounts, but some may consider just one year if the wider application is strong. A whole-of-market broker can identify lenders comfortable with a shorter trading history.
Do self-employed borrowers need a bigger deposit?
Not usually. The minimum deposit is typically the same 5% to 10% as for employed applicants. A larger deposit can, however, open up more lenders and better rates, which can be especially helpful where income varies year to year.
How do lenders calculate self-employed income?
Sole traders are generally assessed on net profit; limited company directors on salary plus dividends, or with some lenders salary plus retained profit. Many lenders average the last two or three years. Approaches vary widely between lenders.
Is it worth using a broker as a self-employed applicant?
For complex or self-employed income, a broker often makes a real difference. They know which lenders treat your income structure favourably and present your case correctly, which can improve both your chances and the amount you can borrow.
