Getting a Mortgage with 1 Year's Accounts: Essential Guide

One of the most common misconceptions about self-employed mortgages is that you need at least two or three years of accounts before any lender will consider you. While it is true that many high street lenders prefer a longer trading history, there is a significant and growing number of mortgage providers who will lend based on just one year’s accounts — sometimes even less. If you have been trading for at least 12 months and have your first set of accounts or SA302 tax calculation, you may have more mortgage options than you think.

This guide explains which lenders accept one year’s accounts, how they assess your income, what documentation you need, and how to present the strongest possible application.

Why Do Most Lenders Want Two or Three Years’ Accounts?

Before exploring the one-year options, it helps to understand why lenders typically ask for multiple years of financial records.

Mortgage lenders need to be satisfied that you can afford the monthly repayments over the full mortgage term, which could be 25 to 35 years. For employed applicants, this is relatively straightforward — a stable salary with payslips provides clear evidence of ongoing income. For self-employed borrowers, income can fluctuate from year to year depending on the health of the business, market conditions, and personal circumstances.

By asking for two or three years of accounts, lenders can see the trend in your income. If your earnings have been stable or growing over multiple years, that gives them confidence that your income is sustainable. If your earnings have dropped significantly, that raises questions.

However, this requirement creates a real problem for people who have recently become self-employed, started a new business, or changed their business structure. You might be earning excellent money right now, but if you have only been doing it for 12 months, many lenders will turn you away.

Which Lenders Accept One Year’s Accounts?

A number of UK mortgage lenders will consider applications from self-employed borrowers with just one year’s accounts. These include some building societies, specialist lenders, and even a handful of high street names. The exact list changes regularly as lenders update their criteria, which is why working with a knowledgeable broker like Option Finance is so valuable — we keep track of which lenders are most receptive at any given time.

Generally, lenders who accept one year’s accounts fall into three categories.

Building societies — several building societies take a more flexible approach to self-employed income than the major banks. They may manually underwrite applications rather than using rigid automated scoring systems, which allows them to consider the full picture of your finances.

Specialist lenders — these are lenders who specifically cater to borrowers that high street banks find difficult to serve, including the newly self-employed, contractors, freelancers, and those with complex income.

Select high street lenders — a small number of mainstream banks will accept one year’s accounts in certain circumstances, particularly if you were previously employed in the same industry or profession before becoming self-employed.

How Is Your Income Assessed With One Year’s Accounts?

When a lender accepts one year’s accounts, they typically assess your income in one of the following ways depending on your business structure.

Sole traders — the lender will look at your net profit as shown on your SA302 tax calculation or in your accountant-prepared accounts. This is your total income minus allowable business expenses. Most lenders then apply an income multiple (typically 4 to 4.5 times) to determine your maximum borrowing.

Partnerships — your share of the partnership profit, as declared on your tax return, is used as your income figure.

Limited company directors — this is where it gets more interesting. Some lenders assess income as salary plus dividends drawn from the company. Others are willing to look at salary plus your share of net profit retained in the company, which can be significantly higher. With only one year’s accounts, the lender willing to consider retained profits alongside salary and dividends can make a substantial difference to your borrowing power. Our mortgages for limited company directors guide explains the various income assessment methods in detail.

What Documentation Do You Need?

With one year’s accounts, thorough documentation is especially important because the lender has less historical data to work with. You should prepare the following.

• SA302 tax calculation — your most recent Self Assessment tax computation from HMRC. This is usually the single most important document for a one-year application.
• Tax year overview — the corresponding HMRC document confirming your tax has been paid and your return is up to date.
• Accountant-prepared accounts — if you have formal accounts prepared by a qualified accountant (ideally a member of ICAEW, ACCA, or CIOT), these carry significant weight with lenders.
• Business bank statements — typically three to six months showing your trading income and business activity.
• Personal bank statements — three to six months showing your personal income and expenditure patterns.
• Evidence of previous experience — if you were employed in the same profession before becoming self-employed, provide references, payslips, or a CV showing this. Lenders view this continuity very favourably.
• Business projections — some lenders appreciate seeing forward-looking projections from your accountant, though this is not always required.
• Proof of deposit and source of funds — standard documentation showing where your deposit has come from.

Factors That Strengthen a One-Year Application

Because you are working with a shorter track record, every aspect of your application that demonstrates stability and reliability becomes more important. Here are the factors that can significantly strengthen your case.

Previous experience in the same field — if you were employed as an accountant for ten years before setting up your own practice, lenders see that as a very different risk profile compared to someone who has entered a completely new industry. Continuity of profession is one of the strongest supporting factors.

A strong first year of trading — if your first year’s figures show healthy income, lenders are more likely to view you favourably. If your income in year one is modest because you were building the business, you may need to wait until year two to get the best deals.

A healthy deposit — with limited trading history, a larger deposit reduces the lender’s risk and opens up more options. While 5% deposits are available, aiming for 10% to 15% gives you access to significantly more lenders and better rates. If you’re a first-time buyer working on your deposit, see our first-time buyer mortgage deposit guide for tips on saving effectively.

Clean credit history — your credit record is always important, but with one year’s accounts it becomes even more critical. Any adverse credit marks will compound the perceived risk of a short trading history. If you do have credit issues, specialist options exist — see our guide to adverse credit mortgages.

Professional qualifications — lenders view qualified professionals (doctors, dentists, solicitors, accountants, architects, and similar) as lower risk. Some lenders have specific professional mortgage products that require only one year’s accounts or even less.

Common Scenarios for One-Year Applications

Here are some real-world situations where borrowers successfully obtain mortgages with just one year of accounts.

Leaving employment to go self-employed — you have worked for an employer in your industry for several years and have now set up on your own. Your first year’s accounts show income in line with or exceeding your previous salary. Lenders see the clear continuity and are often comfortable lending.

Starting a new business — you have launched a new venture and after your first full year of trading, you have solid accounts. If the business is in a sector where you have relevant experience, multiple lenders will consider your application.

Changing business structure — you have been a sole trader for years but have recently incorporated as a limited company. Some lenders treat the incorporation as a new business, even though your trading history is much longer. A good broker will find lenders who recognise the continuity of your underlying business.

Returning to self-employment — if you were self-employed previously, moved into employment, and have now returned to self-employment, some lenders will take your previous self-employed history into account alongside your most recent year’s accounts.

What If You Have Less Than One Year’s Accounts?

If you have been trading for less than 12 months and do not yet have a complete set of accounts, your options are more limited but not non-existent.

Some specialist lenders and building societies will consider applications from borrowers with as little as 6 months of trading history, particularly in the following circumstances:

• You are a contractor with a current contract showing your day rate and contract terms. Read our contractor mortgages guide for more details.
• You are a CIS subcontractor with CIS payment and deduction statements showing regular income. See our CIS mortgages guide for specific CIS mortgage information.
• You are a professional (doctor, solicitor, or similar) with a clear career trajectory.
• You can provide bank statements showing consistent income deposits.

For contractors specifically, specialist lenders often use day rate calculations rather than accounts-based assessments, which can be far more favourable.

The Role of Your Accountant

Your accountant plays a more important role in a one-year mortgage application than you might realise. Beyond preparing your accounts, they can provide supporting documentation that strengthens your case with lenders.

Accountant’s certificate or reference — some lenders accept (or require) a certificate from your accountant confirming your income for the trading period. This is a formal letter on headed paper, signed by the accountant, stating your net profit or income figure. It carries particular weight when the accountant is a member of a recognised professional body.

Projected income — while not all lenders require this, a forward projection from your accountant showing expected income for the current and next financial year can help reassure underwriters that your business is sustainable. This is especially valuable if your first year’s income was strong and you expect it to continue or grow.

Tax return preparation — ensuring your Self Assessment return is filed promptly and accurately is critical. Your accountant should file your return as early as possible after the end of the tax year so that your SA302 is available when you need it. Delays in filing mean delays in your mortgage application.

Choose an accountant who understands the mortgage application process and is willing to respond promptly to lender queries. Some lenders will contact your accountant directly to verify figures, so their availability and responsiveness matters.

Interest Rates and Costs

A common concern among borrowers with one year’s accounts is whether they will face significantly higher interest rates. The answer depends largely on which lender you use and how strong the overall application is.

If you apply to a specialist lender who charges a premium for one-year applications, you may pay slightly more than someone with three years of accounts and an otherwise identical profile. However, several building societies and mainstream lenders who accept one year offer their standard rates, meaning you are not penalised at all for your shorter trading history.

Your loan-to-value ratio has a much bigger impact on your rate than your trading history in most cases. A borrower with one year’s accounts and a 25% deposit will typically get a better rate than a borrower with three years’ accounts and a 5% deposit.
