Self-Employed Mortgage With One Year's Accounts: Which Lenders Will Consider It

The two-year rule is real — most mortgage lenders will not consider a self-employed application without at least two years of trading history. But "most lenders" is not all lenders, and the specialist market that will consider one year's accounts is larger than many applicants realise.

This article explains what specialist lenders who will work with one year of accounts actually look for, how income is calculated, what LTV restrictions typically apply, and how to give the application the best possible chance.

Why Two Years Is the Default

Lenders require two years of accounts because they want to see a trading pattern — not just that the business is generating income, but that it has done so consistently and that the income figure used to calculate the mortgage is a reliable representation of ongoing earnings rather than a one-off.

With two years of data, a lender can average income across the period, assess whether the business is growing or contracting, and build a more confident picture of what the applicant is likely to earn going forward. With one year, they are relying more heavily on a snapshot — and that carries more risk from the lender's perspective.

The two-year rule is not a regulatory requirement. It is a risk management policy, and different lenders have drawn their own lines on how much risk they are prepared to accept. The ones who will consider one year's accounts have done so deliberately, with specific criteria designed to manage that additional risk.

What Specialist Lenders Look For With One Year's Accounts

Not all one-year applications are treated equally. The factors that make the difference:

Business type and sector stability: lenders are more comfortable with established sectors — professional services, technology, construction, healthcare, creative industries — than with genuinely novel business models or highly cyclical sectors. A freelance graphic designer with one year of accounts operating in a well-understood sector is a more legible risk than a startup in an emerging market.

Prior employed income in the same field: if you were previously employed in the same industry before becoming self-employed, some lenders will take that prior employment history into account as evidence of skill and sector stability. A solicitor who has been practising for ten years and went sole trader 14 months ago is a very different profile to someone who has no prior track record.

Profit level relative to the mortgage: a business generating £120,000 net profit in its first year applying for a £400,000 mortgage is in a different position to a business generating £30,000 net profit applying for the same amount. The income-to-loan ratio matters — lenders have more tolerance for one-year accounts when the loan is well within the assessed income multiple.

Clean personal credit: with one year's accounts, lenders have less trading history to rely on, which makes personal credit history more important. No missed payments, no CCJs, no active IVAs or bankruptcies. Some lenders will consider a satisfied default, but unsatisfied adverse credit alongside one year's accounts is very unlikely to succeed.

Accountant-prepared accounts: self-assessed SA302 figures are accepted by some lenders, but certified or ICAEW-prepared accounts carry more weight. If your accounts are prepared by a chartered or certified accountant, make sure that is clear in the documentation.

How Income Is Calculated

Income assessment for one-year self-employed applications follows the same broad rules as two-year applications, but lenders typically have less flexibility in how they apply them.

Sole traders and partnerships: net profit as shown on the SA302 or certified accounts. For a one-year application, there is no averaging — the lender uses the single year's figure. This can work in your favour if income is strong and growing, or against you if the first year was atypically low (for example, because you spent part of the year setting up).

Company directors: the most common approach is salary plus dividends drawn. Some lenders who will consider one year's accounts will also look at salary plus net company profit — the approach that matters for directors who retain profit in the business rather than drawing it personally. With one year's limited company accounts, net profit assessment is more restricted and fewer lenders will apply it.

Day-rate contractors: this is where one-year self-employment becomes a different conversation entirely. Some lenders who will not consider one year of accounts for a sole trader or director will annualise a contractor's day rate — treating the gross contract day rate multiplied by 46 or 48 weeks as the income figure, without relying on accounts at all. If you are a contractor working on day-rate engagements, the applicable criteria depend heavily on whether your lender is assessing you as a self-employed person or as a contractor.

LTV Restrictions

Most lenders who will consider one year's accounts will not offer 95% or 90% LTV. The most common limit is 75–80% LTV, meaning a minimum 20–25% deposit. Some lenders will go to 85% in specific circumstances, but this typically requires a very strong income multiple and excellent credit.

The practical implication: if you have a 10% deposit and one year's accounts, your options are very limited. A 20–25% deposit with one year's accounts opens the specialist market meaningfully. This is worth factoring into timing decisions — if you can wait another 12 months and build deposit alongside a second year's accounts, the combination of lower LTV requirement and two-year history materially improves both your options and your rate.

The Trading Structure Change Problem

One of the most common traps is the sole trader to limited company switch. Many sole traders incorporate once their income reaches a certain level, for tax efficiency reasons. The problem is that incorporating creates a new legal entity — and most lenders treat the limited company as a fresh business, even if the underlying trading activity is continuous.

A sole trader who incorporates after two years of sole trader accounts and then applies for a mortgage three months after incorporation will often find lenders treating them as having three months of limited company trading history, not two years of business track record. Some specialist lenders will take a more holistic view, considering the combined history of sole trader and limited company accounts where the nature of the business is clearly continuous. But this requires careful lender selection and clear documentation of the transition.

The practical advice: if you are planning to incorporate and also planning to buy within the next two years, discuss the timing of both decisions with a mortgage broker before you act. The sequence and timing can materially affect what is available to you.

What Strengthens a One-Year Application

Beyond the factors above, several practical steps improve a one-year application's chances:

Maximise the deposit: LTV is the primary lever for accessing the specialist market with one year's accounts. Every percentage point of additional deposit improves your options.

Use a chartered accountant: ICAEW or ACCA-prepared accounts carry more credibility with specialist underwriters than self-prepared figures. If you are not already using a chartered accountant, the cost is typically recovered many times over in the mortgage rate differential.

Have the SA302 ready: even if you are using certified accounts, lenders will ask for the SA302 and tax year overview from HMRC. Request these in advance — HMRC can take two to three weeks to issue them by post (though they can be accessed online through the self-assessment portal immediately for most applicants).

Document business income sources: if your income comes from a handful of long-standing clients or contracts, evidence of those relationships (contracts, invoices, letters of engagement) can support the picture of business stability even within a single year of trading.

Time the application to capture the strongest income year: if your business had a strong year and you have just passed the 12-month mark, applying promptly means using that year's income before a potentially weaker period dilutes the picture. If your first year was lower due to setup costs and year two is growing strongly, it may be worth waiting to use the two-year average.

The Honest Assessment

One year's accounts is possible, but it is a more restricted market, at a higher deposit requirement, with less rate competition. If your income is strong, your credit is clean, your sector is established and your deposit is 20% or above, there are lenders who will consider you — and with specialist broker support, a mortgage offer is achievable.

If any of those conditions are not met, the more useful conversation is usually about what needs to change — and whether waiting to accumulate a second year of accounts is the right call.
