Self-Employed Mortgage UK 2026: One Year of Accounts?

If you are self-employed and applying for a UK mortgage in 2026, the question that decides almost everything is how many years of accounts you can put on the table. Two years is the default a high-street lender will quote at the start of the conversation. Three years is what a more cautious underwriter wants. One year is achievable through a small group of lenders if the underwriting case is otherwise strong and the most recent return shows a clear profit figure. None of those numbers are written into law. They are policy choices, and the policy varies enough between lenders that the difference between "no" and "yes" on the same application is often "we asked the right bank". The bigger picture sits in the rent vs buy equation and the menu of products in the UK mortgage types guide; this article is the version for the trader, contractor, or company director walking the same path.

The good news is that the self-employed mortgage rate gap that used to exist in the UK has all but disappeared. Self-cert mortgages were banned in 2014 by the FCA's Mortgage Market Review. Every UK lender now applies the same affordability tests to self-employed and PAYE applicants. The cost of being self-employed is paperwork and time, not interest rate. A clean two-year sole-trader case at 80% LTV in 2026 generally prices at the same headline rate as a PAYE applicant with the same deposit. The price tag is the underwriting clock, and that is shorter than the conventional wisdom suggests if you walk in with the right documents already collected.

This guide walks the year-of-accounts rule, the documents lenders actually need, what counts as your income for sole traders versus limited company directors versus contractors, where the 1-year-accounts exception comes in, and how to time the application to the cheapest rate window of the year.

What counts as self-employed for a UK mortgage lender

UK mortgage lenders define "self-employed" more broadly than HMRC does. From the underwriter's point of view, you are self-employed if your income is not delivered to you through a third party's PAYE payroll. That covers:

• Sole traders with a Unique Taxpayer Reference, filing annual Self Assessment.
• Partners in a partnership or LLP.
• Limited company directors holding 20%+ of the company shares. (Below 20%, most lenders treat you as a PAYE employee of the company.)
• Contractors working through a personal service company or umbrella, even if the underlying contract is single-client.
• CIS-registered tradespeople under the Construction Industry Scheme.
• Freelancers with multiple clients, no fixed employer.

If your income mix is "PAYE plus a side hustle" and the side hustle is below the £1,000 trading allowance, you are usually treated as PAYE by the lender and the side hustle is ignored. Once the trading income passes a few thousand a year and shows up on your Self Assessment, lenders start adding it to the income picture (and they like to see two years of it in the same way they do for full-time sole traders).

If your only income is from your own limited company, the question of whether you are "self-employed" or "an employee of your company" is the start of the conversation. Most lenders treat company directors as self-employed for underwriting purposes. A few (notably some building societies) treat directors as employees if the company has a multi-year filing history, which can be a useful angle on a difficult case.

The two-years-of-accounts rule and the one-year exception

The default position across UK lenders is two full years of self-employed accounts, evidenced by:

• Two SA302 tax calculations from HMRC, one for each completed Self Assessment year.
• Two Tax Year Overviews (the document that proves the tax was paid).
• For limited company directors, two sets of full company accounts filed at Companies House.

A more cautious group of lenders ask for three years. They tend to be the largest building societies, the international banks lending into the UK market, and the lower-LTV specialist lenders. If the application is straightforward and the headline rate is competitive, three years is not a refusal, just a wait.

The interesting category is the one-year-of-accounts lender. As of June 2026, the names a specialist broker will reach for first include the following (lender criteria sheets change quarterly, so confirm with a current broker before applying):

• Halifax (for sole traders with one full year of accounts, strong recent year, clean credit).
• Kensington Mortgages (contractors and limited company directors at one year, with broker submission).
• Clydesdale Bank / Virgin Money (contractors on day-rate basis after twelve months in the role).
• Aldermore (specialist self-employed lender, one year of accounts on most cases).
• Vida Homeloans (specialist, will consider one year and retained profits).
• Kent Reliance (specialist, will lend at one year, higher rate).
• Together Mortgages (specialist, will look at six months of self-employment in narrow cases, at a meaningful rate premium).
• Newcastle Building Society (one year for limited company directors).
• Skipton Building Society (contractors at twelve months on a clean case).

These are policy lists that change quarterly. A specialist broker has the latest version of the criteria sheets and will know which lender is currently accepting which type of one-year case. The criteria are tighter than two-year cases. Expect to need:

• A clean credit file with no recent defaults or missed payments.
• A deposit of at least 15% to 25%, with the 25% deposit getting access to the most competitive rates.
• An accountant's reference letter on letterhead, projecting at least the same income level for the current year.
• Six months of business bank statements showing the income flowing through.

The 1-year-of-accounts rate is usually slightly higher than the 2-year-of-accounts rate at the same LTV, often 0.2% to 0.5% higher. Over a five-year fix on a £250,000 mortgage that is £2,500 to £6,250 of additional interest paid. Whether that gap is worth paying depends on whether the alternative is waiting twelve to fifteen months for the second Self Assessment to land. For a first-time buyer racing house price inflation, the gap is often the cheaper option.

What lenders actually use as your income

The single most common misunderstanding among new self-employed applicants is that lenders use the figure on your business bank account as your income. They do not. They use the figure on your tax return as filed with HMRC.

For a sole trader, that is your net trading profit as reported on the Self Assessment - turnover minus expenses minus capital allowances. A trader who turned over £80,000 of revenue and claimed £30,000 of legitimate expenses has a £50,000 SA302 figure. The lender multiplies the £50,000 by their income multiple (typically 4 to 4.5 times). The £80,000 of turnover is irrelevant. The £30,000 of expenses, which was a perfectly legitimate tax deduction, lowers your borrowing capacity by roughly £130,000 at 4.5 times income.

That is a real trade-off. Aggressive expense claiming reduces the tax bill in year one and reduces the mortgage in year two. Some applicants deliberately under-claim expenses in the two-year run-up to a mortgage application, paying more tax than they technically need to, in order to show a higher SA302 figure. It is a legitimate strategy. It is also the kind of thing your accountant will not flag unprompted because their incentive is to minimise tax in the year they file. Bring it up explicitly when you know a mortgage is on the horizon.

For a limited company director, the underwriter takes:

• Salary (PAYE drawn from the company).
• Plus dividends declared and paid to the director.

That is the standard treatment, and roughly two-thirds of UK mainstream lenders use it. Some, including Halifax, Clydesdale, and a few specialists, will alternatively use:

• Salary plus retained profits left in the company for the year.

The retained-profits route can produce a much higher income figure if the director has deliberately kept profits inside the company for tax reasons (paying corporation tax at 25% instead of taking dividends at 33.75% plus). For a director on a £12,570 salary plus £60,000 of retained profits, the salary-plus-dividends number is £12,570 and the salary-plus-retained-profits number is £72,570. That difference takes the maximum borrow from about £56,000 to about £326,000. The retained-profits lenders are the right route if your tax strategy has been to leave profits inside the limited company.

The documents to collect before you apply

The application file every UK mortgage broker will ask for from a self-employed applicant. Get all of these into a folder before your first conversation:

• SA302 tax calculations for the last two (or three) tax years. Download these from your HMRC Personal Tax Account. See the SA302 guide for the step-by-step.
• Tax Year Overviews for the same years, also from HMRC.
• Last three months of personal bank statements for the account your income is paid into.
• Last six months of business bank statements (for sole traders and limited company directors).
• Last two sets of full company accounts (limited company directors).
• Accountant's reference letter on letterhead, confirming income figures, time in business, and a forecast for the current year. Most accountants charge £75 to £150 for this; some include it free with the annual tax service.
• CIS payment certificates (for tradespeople under the Construction Industry Scheme).
• Current contract or recent invoices (contractors).
• Proof of identity and address in line with the usual KYC requirements (driving licence or passport plus a recent utility bill or council tax letter).
• Proof of deposit showing the source of the money, not just that it exists. If a parent gifted the deposit, the parent will need to sign a gift letter. Inherited money needs probate evidence. Sale proceeds need the completion statement.

The single document that catches most first-time self-employed applicants is the accountant's letter. Accountants are busy in January and April. Ask for the letter in November or May, not at the same time you ask them to file the return.

Limited company directors: the retained profits question

Limited company directors face a structural mismatch between their tax planning and their mortgage application. Tax planning for a small limited company typically says:

• Pay yourself a low salary up to the National Insurance threshold (~£12,570 in 2026/27).
• Take dividends up to the basic-rate band if you can afford to.
• Leave the rest in the company, paying 25% corporation tax, to avoid the 33.75% higher-rate dividend rate.

That is sensible. It minimises overall tax. It also reports a salary of £12,570 plus dividends of (say) £37,700, totalling £50,270, on the SA302. A mainstream lender doing salary-plus-dividends will lend you about 4.5 times £50,270, or roughly £226,000. If the same company actually generated £150,000 of profit and £100,000 of that sat inside the company as retained profit, you have £100,000 of income the lender is not seeing.

Three options:

• Apply to a retained-profits lender (Halifax, Clydesdale, Kensington, Vida, Newcastle BS). They will look at the full company picture and lend on salary plus retained profits. The accountants' letter and full Companies House accounts become the load-bearing documents.
• Pay yourself a special dividend in the year before the application. This is a one-time decision that converts retained profits into reported dividend income on the next year's SA302. The cost is the higher-rate dividend tax (or the additional-rate tax above £125,140). The benefit is access to mainstream salary-plus-dividends lenders with cheaper rates and faster underwriting.
• Wait for the company's filing history to lengthen. A five-year-old company with consistent retained profits gets treated more flexibly by underwriters than a two-year-old company in the same position. If the application is not urgent, time is the cheapest route.

If you run a one-person limited company and have never had this conversation with your accountant, raise it explicitly six months before any mortgage application. The right tax answer for the year you file is not necessarily the right tax answer for the year you borrow. The trade-offs between operating as a director and operating as a sole trader sit in the limited company vs sole trader guide and feed directly into this question.

Contractors: the day-rate route

Contractors with a single-client personal service company sit in a category many lenders treat as a hybrid of self-employed and PAYE. The headline route is the day-rate underwriting model, which works like this:

• The lender takes the contractor's current day rate.
• Multiplies by an assumed number of weeks worked per year (typically 46 to 48).
• Treats the result as the gross income figure for affordability.

A contractor on £500 a day at 47 weeks is treated as having £117,500 of gross income, regardless of what the SA302 shows. That figure goes into the standard 4.5x income multiplier, giving a £528,000 maximum borrow. The same contractor with one year of accounts showing a net £55,000 personal income (after company-side expenses and a tax-efficient salary-and-dividend mix) would be limited to £247,500 on the salary-and-dividends route.

The day-rate route is available from Halifax, Clydesdale / Virgin Money, Kensington, Skipton, and a small number of specialist lenders. The criteria are tight:

• A current contract with at least three months still to run.
• A contract day rate, not an annual salary, in writing.
• Twelve months of total contracting history (Halifax may go to six).
• A CV showing employment continuity (a previous PAYE role in the same field is usually fine).
• Some lenders also want a gap-of-no-more-than-six-weeks rule between contracts.

The day-rate route disappears the moment your contract converts to PAYE or back to a long-term employment basis, so the time-in-the-window matters. If you have been contracting for a year and have a six-month renewal in hand, that is the moment to apply.

How LTV and interest rate are affected

Loan-to-value and interest rate for self-employed mortgages in 2026 work like this:

• At 60% LTV and below: rates are functionally identical to PAYE applicants. Every mainstream lender competes for this business.
• At 75% to 85% LTV: rates are within 0 to 0.2 percentage points of the equivalent PAYE rate. Almost no premium.
• At 90% LTV: the lender panel shrinks. Some specialists will not lend above 85% LTV to a one-year-accounts self-employed applicant. The mainstream lenders will, at rates 0.1 to 0.3 percentage points above the PAYE equivalent.
• At 95% LTV: the panel shrinks further. The government's Mortgage Guarantee Scheme is technically available to self-employed applicants but most participating lenders restrict it to two-year-plus cases. A one-year-accounts case at 95% LTV is hard; broker-led is essential.

For a clean two-year self-employed case the practical answer is "your rate is the same as a PAYE applicant's at the same LTV, your application takes a week or two longer". For a clean one-year self-employed case the answer is "your rate is 0.2 to 0.5 percentage points higher and you should expect to need a broker who has done it before".

The other LTV effect worth flagging: the LTV band overpayment maths applies to self-employed remortgages too. Crossing the 75% LTV threshold at a remortgage repricing event can save more interest across the next fix than a year of overpayments did. Self-employed applicants with a successful business and rising profits can compound this effect by underwriting at a higher income figure next time around.

When a specialist self-employed broker earns the fee

A standard mortgage broker (independent or whole-of-market) handles a self-employed case competently for most applicants. The cases where a specialist self-employed broker is worth their fee:

• One year of accounts applications. The specialist knows which lender is currently accepting which kind of one-year case and the order to approach them in. A standard broker may guess wrong on the first attempt, which leaves a hard credit footprint and weakens the next.
• Limited company directors with significant retained profits. Three of the five major retained-profits lenders use slightly different definitions of "retained profits" (some include the current year's profit, some only prior years). A specialist will know which company's figures fit which lender's policy.
• Contractors switching from PAYE in the last year. The day-rate route requires the right narrative. A specialist will frame the application correctly the first time.
• Recent dip in income. A year of lower profits (caused by a sabbatical, a maternity leave, a major client loss, COVID disruption still showing in 2023 returns) needs a specialist to find the lenders who underwrite on the strongest year rather than the most recent year.
• Mixed income (PAYE plus self-employed). Underwriting on the combined picture sometimes works and sometimes does not. The specialist will know.
• Adverse credit history plus self-employment. The specialist sub-prime lenders (Together, Bluestone, Pepper, Vida) lend on different criteria and have completely different underwriting cultures.

Specialist broker fees typically run £400 to £700, payable on offer. Some take a procuration fee from the lender and charge no fee to the applicant; some charge an upfront fee that is refunded against the broker fee on completion. Ask for the fee structure in writing at the first meeting.

For a straightforward two-year self-employed case at 75% LTV with a clean profile, a standard broker or a direct online application is fine. The specialist earns their money on the edge cases.

Frequently asked questions

Can you get a mortgage with one year of self-employed accounts UK?

Yes. A small group of UK lenders will lend on one year of self-employed accounts if the most recent return shows a strong, profitable position and the rest of the application is clean. The names a specialist broker will reach for first in 2026 are Halifax, Kensington, Clydesdale, Aldermore, Vida, Kent Reliance, Newcastle Building Society, and Skipton. The rate is usually 0.2 to 0.5 percentage points higher than a two-year case at the same LTV. Expect to need a 15% to 25% deposit and an accountant's reference letter.

How many years of accounts do mortgage lenders need?

Most mainstream UK mortgage lenders ask for two full years of accounts evidenced by SA302s, Tax Year Overviews, and (for limited company directors) Companies House filings. A more cautious group ask for three years. A specialist minority will accept one year if the most recent year is strong. The default to plan for is two. Filing your annual Self Assessment early in the year (April or May rather than January) maximises the window of mortgage offers available against the most recent year's figures.

Is it harder to get a mortgage if you're self-employed UK?

It is harder in the sense of more paperwork and a longer underwriting clock, not in the sense of a higher interest rate. Self-cert mortgages were banned in 2014 and every UK lender now applies the same affordability tests. Rates for a clean two-year self-employed case are functionally identical to the PAYE equivalent at the same LTV. The friction is in proving the income, not in the price tag.

What income do mortgage lenders use for self-employed?

Sole traders are assessed on the net trading profit reported on the SA302 (turnover minus expenses minus capital allowances). Limited company directors are assessed on salary plus dividends, or on salary plus retained profits at lenders that allow it (Halifax, Clydesdale, Kensington, Vida, Newcastle BS). Contractors are typically assessed on day rate multiplied by 46 to 48 weeks worked per year, which often produces a higher figure than the SA302 alone.

How much can self-employed borrow on a mortgage?

The income multiple is the same 4 to 4.5 times income that mainstream UK lenders use for PAYE applicants. A sole trader with an SA302 net profit of £45,000 can typically borrow £180,000 to £202,500. A limited company director with £12,570 salary plus £37,700 dividends is in the same range. The same director assessed on salary plus £80,000 retained profits could borrow up to roughly £415,000 at a retained-profits lender. A contractor on £500 a day at 47 weeks is assessed at £117,500, supporting a maximum borrow of around £528,000.

Do I need a bigger deposit if I'm self-employed?

For two-year-accounts cases, no. The standard deposit thresholds (5%, 10%, 15%, 25%, 40%) apply identically. For one-year-accounts cases, expect to need at least 15% to access competitive rates and 25% for the cheapest deals. The 95% LTV tier shrinks meaningfully for self-employed applicants on one year of accounts and is hard to reach at all without a specialist broker.
