Will Lenders Use My Latest Year's Profit or Average It?
- Jun 25
- 10 min read
Whether a lender uses your latest year's profit or an average depends mostly on which way your profits are heading. When they are rising, many lenders will use your most recent year; when they are falling, they tend to take the lower figure.
Quick Answer
It varies by lender, and the deciding factor is your profit trend. If your self-employed profits are rising year on year, a good number of lenders will use your latest, higher year, which is the best case for how much you can borrow. If profits are broadly steady, most lenders average your last two or three years.
If they are falling, lenders usually lean on the lower of your latest year or the average, to be cautious. Because lenders differ so much on this, the right one can make a real difference to your maximum loan, and a broker's job is to find the lender whose approach fits your figures.
This guide covers how lenders read the numbers, not how you should arrange your accounts for tax, which is a question for your accountant. The practical takeaway is that your maximum loan is not fixed by your accounts alone; it is shaped just as much by which lender reads them. For a self-employed borrower, that makes the choice of lender every bit as important as the figures themselves.

Who This Guide Is For
Best for self-employed sole traders, partners and limited company directors trying to work out how much they can borrow, especially where one year looks very different from the next. It suits anyone whose profits have jumped, dipped or bounced around, and who wants to understand which figure a lender will actually lend against. If your income is straightforward and flat, this matters less; if it moves about, the lender you choose can change your borrowing noticeably. It is also useful for anyone who has been quoted a low figure by their own bank and suspects, rightly, that another lender might see their income more generously.
Key Points
Your profit trend decides the figure: rising favours the latest year, falling favours the lower number
Lenders vary widely: the right one for your figures can mean a meaningfully larger loan
Evidence and timing matter: clean accounts and the right moment to apply both help

The two ways lenders read your profit
When a lender works out your self-employed income, it almost always starts from one of two figures: your latest year's profit on its own, or an average of your last two or three years. The graphic sets out the difference. Neither is universally right, and lenders genuinely split on which they prefer, which is why two lenders can offer quite different loan amounts on the same accounts. It is worth pausing on that, because most people assume there is one right number a lender simply reads off their accounts, when in reality the figure is a choice the lender makes, and different lenders choose differently. Two equally creditworthy businesses with identical paperwork can therefore walk away with materially different mortgage offers, purely because they approached lenders with different house styles.
For a sole trader, the figure is usually your net profit; for a company director it is typically salary plus dividends, and sometimes a share of retained profit. The basis differs by structure, and our companion guides on self-employed mortgages and director income go into that in detail. The point here is simpler: once a lender has settled on your income basis, it then decides whether to use your latest year or an average, and that single choice often moves your maximum loan more than anything else. Understanding which of the two methods a given lender uses, before you apply, is the single most useful thing you can know about your own borrowing. It is the quiet lever behind a surprising number of self-employed mortgage outcomes.
Why the trend decides which figure they use
The reason lenders care about the two methods is risk. A single strong year might be a one-off; an average smooths out the bumps. So most lenders look at the direction your profits are travelling and pick the figure that protects them. The graphic and table below show the typical pattern, though every lender sets its own rules and these are guides rather than promises. The underlying logic is straightforward once you see it: a lender is trying to estimate the income you can reliably sustain, not the best you have ever done, so it leans towards caution whenever your figures are heading the wrong way. Crucially, none of this is personal or arbitrary; it is the same cautious arithmetic applied to everyone, which means it is predictable enough to plan around. Once you understand the logic, a low quote from one lender stops feeling like a verdict and starts looking like one opinion among many.
Your profit trend | The figure lenders typically use |
Rising year on year | Often your latest, higher year (best case for borrowing) |
Broadly steady | An average of your last two or three years |
Falling year on year | Usually the lower of the latest year or the average |
A one-off dip, then recovered | Some lenders look past the dip with a clear explanation |
That last row is where a broker earns their keep. If you had one weak year for a reason you can evidence, a global pandemic, a big one-off cost, a quarter of parental leave, some lenders will set it aside and lend on your stronger years. A broker who places self-employed mortgages knows which lenders take that view, and steering your application there can be the difference between a disappointing offer and a comfortable one. It is also worth knowing that lenders vary in how many years they will look back, and how much weight they give the most recent one, so even within the same trend there is room to find a more generous reading. Where two or three of your recent years are all strong, you are in the easiest position of all, because almost any method a lender chooses lands on a healthy figure. The wrong lender, by contrast, can cost you tens of thousands in borrowing capacity on exactly the same accounts.
Case study: a strong year after a quiet one
The following is an illustrative example, not a quote or a guaranteed outcome. A self-employed designer had profits of around 38,000 pounds one year and 72,000 the next, after winning a major client. Her own bank averaged the two, which capped her borrowing well below the home she wanted, and she assumed that was simply how it worked. The gap between the two years was not a red flag, it was a success story, but an averaging lender treats a leap upwards much the same as it would treat volatility. She had effectively doubled her income, yet the offer she was given barely reflected the smaller of her two years. To her, the two answers felt like a rule of nature; in fact they were just two lenders with two policies.
It was not the only way. We took the case to a lender comfortable using the latest year where profits are clearly rising and the business looks sustainable. With her most recent figure accepted, her borrowing rose substantially and the purchase went ahead. Nothing about her accounts changed between the two answers, only the lender's approach to which year to use. It is one of the most common self-employed situations we see, and one where simply choosing the right lender, rather than accepting the first answer, changes the outcome entirely. The lesson is not that her bank was wrong, only that it was one lender with one policy, and the market holds many others. We see versions of this most weeks, and the fix is almost never financial engineering; it is simply knowing the panel well enough to pick the lender that suits the shape of the income.
How to put your strongest figure forward
A little preparation helps a lender read your income at its best. Start with clean, finalised accounts or tax calculations, because lenders want to see the figures evidenced, usually through your tax year overviews and computations or an accountant's certificate. Vague or provisional numbers slow everything down and make a cautious lender more cautious. Most lenders will want to see your figures backed by HMRC documents, typically your tax year overviews and tax calculations, or accounts signed off by a qualified accountant, so having those ready before you apply removes a common source of delay. It also helps to make sure your accountant's figures and your HMRC documents tell exactly the same story, as any mismatch invites questions. Getting the paperwork straight is dull but decisive.
Timing matters too. If your strongest year has just closed and been filed, applying once it is on record can lift your borrowing, whereas applying just before it is finalised may force a lender back onto older, lower figures. It is worth a quick conversation about when your latest year lands before you commit to an application. Equally, if your latest year is shaping up weaker than the one before, there can be sense in applying while the stronger year is still the most recent on record, rather than waiting for a softer figure to replace it. A short planning conversation before you apply often saves a great deal of frustration later.
Finally, be ready to explain any wobble. A short, honest note about a dip, a one-off cost, or a change in the business does far more good than leaving a lender to guess. The aim is to present a clear, evidenced story so the right lender can confidently use your strongest sensible figure. How you arrange your income between salary, dividends and retained profit is a matter for your accountant; a broker simply works with whatever the figures are and finds the lender that reads them most generously. None of this is about presenting your business as something it is not; it is about making sure the true picture is easy for a lender to understand and act on, and a broker presents that picture for you, in the format and to the lender most likely to act on it.
Common myths about self-employed profit
A lot of self-employed worry comes from myths rather than how lending works. The first is that lenders always average your years. Many do, but plenty will use your latest year when profits are rising, so a strong recent year is far from wasted. Assuming the average is the only option leaves money on the table. If you have had a genuinely strong recent year, it is worth actively seeking out the lenders that will reward it rather than settling for one that quietly averages it away. The averaging habit is real, but it is far from universal, and that gap is where better offers live.
The second is that one bad year ruins everything. It rarely does. Lenders are used to businesses having an off year, and with a clear explanation and stronger surrounding years, many will look past a single dip rather than fixate on it. A bad year shapes which lender fits, not whether you can borrow at all. Lenders see far more accounts with the odd difficult year than people imagine, and a coherent explanation goes a long way. What matters is the trajectory and the explanation, not the existence of a single soft year.
The third is that all lenders treat self-employed income the same, so there is no point shopping around. The opposite is true: this is one of the areas where lenders differ most, on the years they use, the income they count, and how they handle directors. That variation is exactly why a broker can add so much, by matching your particular figures to the lender that reads them best. Treating all lenders as interchangeable is the most expensive assumption a self-employed borrower can make, and the effort of comparing is small next to the difference it can make to what you can borrow.
FAQs
Do mortgage lenders use my latest year or an average?
It depends on the lender and your profit trend. When profits are rising, many lenders use your latest, higher year; when they are steady, most average two or three years; when they are falling, they tend to use the lower figure. Because lenders differ, the right one can mean a noticeably larger loan, which is what a broker is matching you to.
I had a strong last year, will lenders use just that?
Some will, especially where the rise looks sustainable and your earlier years support it. Others will still average, which dilutes the strong year. The trick is to find a lender comfortable using your latest year, rather than accepting the first one that averages it down, and that is where broker knowledge pays off.
My profits dropped last year, what figure will they use?
Usually the more cautious one, often the lower of your latest year or the average. But if the dip was a one-off you can explain and evidence, some lenders will look past it and lend on your stronger years. The explanation and the choice of lender matter more than the dip itself.
Do lenders look at my turnover or my profit?
Profit, not turnover. Lenders assess what the business actually earns you, your net profit as a sole trader, or salary plus dividends (and sometimes retained profit) as a director, rather than the money passing through the business. A high turnover with thin profit will not borrow as much as people expect.
How many years of accounts do I need for a self-employed mortgage?
Most lenders want two to three years, but a fair number will consider one year's accounts in the right circumstances. The fewer years you have, the more the individual lender's policy matters, so a broker who knows which lenders accept shorter trading histories is especially useful early on.
Can a broker get a lender to use my best year?
A broker cannot change a lender's rules, but they can place you with the lender whose rules already favour your situation, including those that use the latest year when profits rise. Matching your figures to the right lender, rather than hoping your own bank is flexible, is the whole value of advice here.
Summary
Whether a lender uses your latest year's profit or an average comes down to your profit trend: rising favours the latest year, steady favours an average, and falling favours the lower figure. Lenders differ widely, so the one you choose can change your borrowing significantly. Clean evidence, good timing and a clear explanation of any wobble all help, and a broker's role is to match your figures to the lender that reads them most generously. The tax side of how your income is arranged is one for your accountant.
