Getting a Mortgage When You're Self-Employed — A Trade's Guide (2026)

Why a Self-Employed Mortgage Feels Harder

When you're employed (PAYE), a lender can see exactly what you earn — your payslips and P60 show a fixed salary, and that's the figure they lend against. As a sole trader, partner or company director, you don't have payslips in the same way. Your income varies month to month, you draw money in different ways, and a chunk of what your business generates never lands in your personal bank account as visible pay.

That's the whole reason self-employed mortgages have a reputation for being difficult. But here's the key point that gets lost: there is no special "self-employed mortgage" product. You apply for exactly the same residential mortgages as everyone else, at the same rates — the only difference is how you prove your income. Get the proof right and you're competing on a level field.

How Lenders Assess Self-Employed Income

Most lenders want to see two to three years of accounts or Self Assessment figures. They'll usually take an average of those years, though some use the latest year, and the more cautious ones take the lowest year — particularly if your income is falling. A rising trend works in your favour; a sharp drop in the most recent year will pull the figure down whatever the average says.

What counts as "income" depends entirely on how your business is structured:

• Sole traders and partnerships: lenders use your net profit — not your turnover. The total invoiced through the business is irrelevant; what matters is profit after allowable expenses, as shown on your Self Assessment. For a partnership, it's your share of the partnership's net profit.
• Limited company directors: most lenders use salary plus dividends drawn from the company. This is where many trade directors get caught out (more on that below).

That limited company point is worth dwelling on. If you pay yourself a small salary plus modest dividends — leaving the rest of the profit in the business to save tax — a standard lender only counts the salary and dividends you actually took. The profit sitting in the company doesn't exist as far as they're concerned, even though it's genuinely yours.

The good news: a growing number of lenders will instead use salary plus your share of the company's net or retained profit, which can dramatically increase the income they recognise for a director who leaves money in the company. Not every lender offers it, and you usually need an accountant to confirm the figures — exactly the kind of case a specialist broker exists to place.

The Key Documents You'll Need

Self-employed applications live or die on documentation. The cleaner and more complete your paperwork, the smoother the process. Expect to be asked for:

• SA302 tax calculations: these are HMRC's summary of your declared income and tax due for each tax year. You can download them from your HMRC online account or your accountant can produce the equivalent.
• Tax Year Overviews: the partner document to the SA302. The SA302 shows what you declared; the Tax Year Overview confirms HMRC received it and that the tax was paid. Lenders almost always want both together, for the same years.
• Certified accounts: ideally signed off by a qualified accountant (ACCA, ACA, AAT, ICAEW or similar). These carry far more weight than self-prepared figures, especially for limited companies.
• An accountant's certificate or lender accountant reference: many lenders send a short form for your accountant to confirm your income, which can stand in place of, or alongside, the SA302s.
• Business and personal bank statements: usually the last three to six months, to confirm your accounts match real cash flowing through the business.

If you've only just filed a return, give HMRC a few days before trying to download your SA302 and Tax Year Overview — they don't appear instantly. Sorting this out before you apply, rather than scrambling mid-application, removes most of the stress.

The Tax-Planning Tension Nobody Warns You About

A good accountant's job, year to year, is to keep your taxable profit and drawings as low as legitimately possible so you pay less tax. That makes complete sense — until you want to borrow. Every pound of profit you write down, and every pound you leave undrawn in a limited company, is a pound the lender won't count as income. The sole trader who maximises expenses, or the director who lives on a tiny salary and small dividends, can end up looking far poorer on paper than they really are — and that smaller declared income directly shrinks how much you can borrow.

The fix is to plan ahead. Because lenders look back over two to three years, you can't reverse this in the month before you apply. If buying or remortgaging is on the horizon, talk to your accountant two to three years out about declaring a higher, more honest profit or drawing more income in the run-up. You'll pay a bit more tax — but buy yourself a much bigger borrowing capacity when it counts.

Deposit, Credit File and Trading History

Income is only part of the picture. The other big levers are your deposit, your credit record and how long you've been trading.

Deposit

You'll typically need between 5% and 25% of the property value. 5% deals exist for self-employed applicants but are limited and priced higher. The more you put down, the better the rate and the wider the range of lenders willing to consider you — a 10–15% deposit opens up far more options than the bare minimum, and 25% gets you close to the best rates on the market.

Credit file

Lenders pull your personal credit file regardless of how you trade. Missed payments, defaults, heavy reliance on overdrafts or a string of recent credit applications all count against you. Check your file (Experian, Equifax, TransUnion) well before applying, make sure you're on the electoral roll, and clear or explain anything that looks bad.

CIS subcontractors

If you work under the Construction Industry Scheme and have tax deducted at source by contractors, you are still self-employed for mortgage purposes — your CIS deductions don't make you employed. Lenders assess you on your net profit via Self Assessment in the normal way. A few specialist lenders work from your CIS payment and deduction statements, which suits subcontractors with limited formal accounts, but most treat you as a standard sole trader.

Trading history

The classic rule is two to three years of accounts, but it's not absolute. Some lenders accept just one year's accounts, particularly if you have a strong track record in the same trade before going self-employed, a healthy deposit and a clean credit file. You have fewer choices with one year, but it is not the brick wall many people assume.

Practical Steps to Get Mortgage-Ready

Most of the work that gets a self-employed mortgage approved happens long before the application. A sensible run-up looks like this:

• Keep clean, organised accounts. Separate business and personal banking, log every invoice and expense, and make sure your figures are easy for an accountant to certify.
• File your Self Assessment on time, every year. Late filings, estimated returns and outstanding tax are red flags. On-time filing also means your SA302s and Tax Year Overviews are ready when you need them.
• Use a qualified accountant. Certified accounts and an accountant who'll complete a lender's reference form make a real difference, especially for company directors.
• Use a mortgage broker who knows self-employed and contractor cases. A good broker knows which lenders use retained profit, which accept one year's accounts, and which understand CIS. This is the single highest-value step for most tradespeople — the right lender choice can be the difference between a decline and an approval.
• Don't pile on big undeclared or unusual expenses right before applying. A sudden drop in profit in your latest year, or large one-off costs, can sink your affordability just when you need the numbers to look strong.
• Get an Agreement in Principle (AIP). This is a lender's provisional indication of what they'll lend, based on a soft check. It tells you your realistic budget, reassures estate agents you're a serious buyer, and surfaces problems before you're committed to a property.

Quick Reference: How Lenders Assess You

Treat this as a guide, not a guarantee — lender criteria vary, and the figure one will lend against can differ significantly from the next. That variation is precisely why a broker who specialises in self-employed cases is worth their fee.

The Bottom Line

Being self-employed doesn't shut you out of the mortgage market — it just changes how you prove what you earn. Keep clean accounts, file on time, understand how your business structure affects the income a lender recognises, and plan your tax position a couple of years ahead if a purchase is coming. Pair that with a decent deposit, a tidy credit file and a broker who knows the self-employed landscape, and you'll be on the same footing as any PAYE applicant.
