Self-Employed and Applying for a Mortgage? Here's What Lenders Actually Want to See

The Bank of England held the base rate at 3.75% again this week, at its meeting on 30 July, and on the face of it that looks like more of the same. Look closer and it's a more interesting story: the vote split 6-3, with three MPC members preferring a rise to 4% rather than another hold. Inflation, meanwhile, fell to 2.6% in June, its lowest reading since March 2025. You'd expect that combination to push fixed mortgage rates down. Instead, average rates have risen for two weeks running, with the typical two-year fix now at 5.57% and the five-year at 5.60%, even as the best buys — around 4.3% to 4.5% for those who qualify — are still out there.

That gap between the headline rate and what borrowers actually get says a lot about how selective lenders have become. And nobody feels that more than self-employed applicants, who tend to get the most scrutiny at the best of times. So this week I want to walk through exactly what lenders are looking for if you work for yourself, and how to put your best case forward.

Why Self-Employed Applicants Get Extra Scrutiny

An employed applicant can hand over a payslip and a P60 and the picture is more or less settled. Self-employed income is messier by nature — it can vary year to year, gets mixed up with business expenses and reinvestment, and doesn't always look, on paper, like it matches your lifestyle. Lenders aren't trying to catch you out; they simply need confidence that your income is genuine, sustainable, and likely to continue. In a market where rates are moving unpredictably in both directions, that caution has, if anything, increased rather than eased.

The Income Lenders Will Actually Count

Most lenders will look at either your net profit if you're a sole trader, or your salary plus dividends if you run your own limited company, typically averaged across your last two to three years of accounts. A single strong year won't carry much weight on its own, and a lender will usually want to understand why income has changed if it's moved sharply in either direction. One-off contracts, retained profits left in the business, and income you're only forecasting rather than earning generally won't count, however real they are to you.

The Documents to Have Ready

Getting these together before you apply, rather than scrambling once you've found a property, makes a real difference to how smoothly things go:

1. SA302s and tax year overviews from HMRC for the last two to three years, or your equivalent limited company accounts.
2. Accountant-prepared accounts, ideally from a qualified or chartered accountant, as lenders generally trust these more than self-prepared figures.
3. Three to six months of business bank statements, showing income arriving in a pattern that matches your accounts.
4. Evidence of ongoing work — signed contracts, retainer agreements or a pipeline of confirmed bookings — to show your income is likely to continue, not just what it has been.
5. Personal bank statements covering the last three to six months, showing your day-to-day spending and any existing credit commitments.
6. Proof of ID and address, and details of any other income, such as rental property or a second business.

Three Mistakes I See All the Time

1. Mixing personal and business spending through the same account, which makes it far harder for an underwriter to see your genuine income at a glance.
2. A sharp dip in one year's income with no explanation attached — even a short covering note from your accountant can turn a red flag into a non-issue.
3. Leaving accounts and tax returns until after you've found a property, which is exactly when you have the least time to sort out any gaps.

My Advice If You're Buying or Remortgaging Now

With the rate picture as mixed as it is right now, self-employed borrowers can't afford to let their own paperwork be the reason a good deal slips away. Sit down with your accountant well before you plan to apply, make sure your last two to three years tell a consistent story, and come to a broker who deals with self-employed cases regularly — not every lender assesses self-employed income the same way, and the right one for your situation isn't always the obvious one.

If you're self-employed and thinking about buying or remortgaging, get in touch and we'll go through your figures together. The first conversation costs nothing and commits you to nothing either.

Kindest regards
