Building Society Mortgage for Self-Employed Borrowers

You can get a building society mortgage when you’re self-employed. You do not normally need a permanent employment contract or monthly payslips. What matters is whether the lender can verify your income, understand how your business earns money and establish that the mortgage is affordable.

The complication is how income is assessed. A sole trader’s taxable profit, a limited company director’s salary and dividends, and a contractor’s day rate may produce very different mortgage calculations. Some building societies also consider applicants with a shorter trading history or more complicated accounts, subject to their individual criteria.

This UK guide explains the documents you need, how lenders assess different business structures, what happens if you have only one year’s accounts, how much you might borrow and where to check official lender requirements before applying.

Check Your Situation Mortgage Document Checklist Compare Building Society Routes
Quick answer: Most self-employed applicants should prepare their latest two years of tax calculations or business accounts, although some lenders request three years and some consider shorter trading histories. A mortgage is not guaranteed simply because your business is profitable.

Self-Employed Mortgage: Quick Facts

Can self-employed people apply? Yes. Sole traders, company directors, partners, contractors and freelancers can be considered.
Typical trading history Two years is a common starting point; some lenders require more or may consider one year.
Income evidence SA302 tax calculations, tax year overviews, accounts, bank statements and other lender-specific evidence.
Deposit Depends on the product, property, credit position and lender’s loan-to-value criteria.
Income used Usually assessed from verified profits, salary, dividends or other acceptable income, not simply business turnover.
Best first step Identify how your income is recorded, then match your situation to the lender’s criteria before making an application.

Can You Get a Building Society Mortgage if You’re Self-Employed?

Yes. Self-employment is not automatically a reason for a mortgage refusal. Building societies assess how much verified income is available to repay the mortgage, alongside your deposit, existing commitments, credit history, household spending and the property itself.

The important difference is that PAYE employees can often demonstrate income through payslips and employment records. Self-employed borrowers usually need to show a longer financial picture.

Sole trader A plumber, electrician, consultant, hairdresser, delivery operator or other individual trading on their own account.
Limited company director Someone earning through salary, dividends or potentially other company income accepted under the lender’s policy.
Business partner Someone receiving an identifiable share of profits from a partnership or LLP.
Contractor or freelancer Someone paid through projects, contracts, invoices or day rates rather than conventional permanent employment.
Where building societies differ: two lenders may reach different affordable borrowing figures from the same accounts because their income calculations, trading-history requirements and treatment of fluctuating profits are not identical.

How Building Societies Calculate Different Types of Self-Employed Income

The first question should be: Which income figure will the lender actually use? A company showing £200,000 of annual sales does not necessarily provide its owner with £200,000 of mortgage-assessable income.

Business structure
Income commonly reviewed
Important consideration
Sole trader
Net trading profit shown in tax records.
Turnover and the amount transferred into your personal account are not the same as taxable profit.
Limited company director
Often salary and dividends; some lenders may also consider an attributable share of company profits.
Company ownership, retained profits and business sustainability can affect the approach.
Partnership or LLP
The applicant’s share of profits or other eligible partnership income.
The lender must understand your individual share rather than the partnership’s full turnover.
Contractor
Accounts-based income or an eligible contract/day-rate assessment.
Contract duration, continuity, gaps and industry experience may matter.

Salary and dividends versus retained company profits

A director who takes a modest salary and dividends while keeping profits in the company may appear to have lower personal income than the business’s underlying financial performance suggests.

Some building society lending policies can consider company profit attributable to the director, but this is not universal. Lenders may inspect the accounts, ownership percentage, cash position and business commitments before accepting such income.

Do not assume retained profit is automatically available: money needed for tax bills, creditors, wages or business operations should not be treated as freely available personal income. Ask a lender or qualified broker how the relevant lending criteria work before relying on a retained-profit calculation.

Can You Get a Mortgage With Only One Year’s Accounts?

Potentially. Having fewer than two years of accounts narrows your lender options, but it does not automatically mean you must wait another full year.

A lender considering one year’s accounts may look more closely at previous work in the same industry, the length of your current contracts, consistent business activity, the stability of your income and any substantial changes since the first accounts were prepared.

What may strengthen a shorter trading history

  • Several years of experience in the same industry.
  • Contracts or a credible continuing client base.
  • Profits supported by bank transactions.
  • A sustainable and understandable business model.
  • A deposit and borrowing request that fit affordability.
  • No significant undisclosed borrowing or tax liabilities.

What may make approval harder

  • Only a few months of trading.
  • Income that has not yet been declared or independently evidenced.
  • Large unexplained changes in profit.
  • Reliance on a single contract that is about to end.
  • Business accounts showing persistent losses.
  • Unresolved tax debts or substantial personal commitments.
Practical approach: before submitting a full mortgage application, ask whether the lender accepts your exact trading history and business type. A broker experienced with self-employed applications may be able to identify lenders without multiple unsuitable applications.

Self-Employed Mortgage Document Checklist

MoneyHelper says lenders commonly ask self-employed applicants for two or three years of accounts and tax evidence, together with bank statements and other information supporting the income declared.

Gathering these records early helps identify discrepancies before an underwriter requests further explanation.

How to Get Your SA302 Tax Calculation From HMRC

An SA302 is evidence of your tax calculation following Self Assessment. It is often requested alongside an HMRC tax year overview, which is a separate document.

HMRC states that tax calculations and tax year overviews are available for the last four years where the relevant returns have been submitted. Online documents may not be available until 72 hours after filing.

SA302 / tax calculation Shows taxable income, allowances and how the tax liability was calculated.
Tax year overview Provides HMRC’s overview for the relevant tax year and may be required alongside the calculation.
Commercial tax software If an accountant filed through commercial software, the tax computation may need to be obtained from that software.

After opening this link:

  1. Read whether your return was submitted through HMRC’s online service or commercial software.
  2. Sign in to your HMRC account if you used HMRC’s service.
  3. Open Self Assessment and find the details of your submitted tax returns and payments.
  4. Download or print the required tax calculation.
  5. Obtain the tax year overview for the same year.
  6. Confirm with the mortgage provider whether the versions you have are acceptable.
Tax years matter: UK tax years run from 6 April to 5 April. For example, the 2025/26 tax year ended on 5 April 2026. A lender may ask for the latest completed tax years and may also request newer management figures if those historic records no longer represent your circumstances.

How Much Can a Self-Employed Borrower Get?

The borrowing amount depends on the income the lender accepts, affordability after expenditure, the deposit, loan-to-value limits, credit history, mortgage term and product eligibility.

Some lenders use an income multiple as one part of the calculation. But being able to demonstrate £50,000 of accepted annual income does not guarantee a mortgage of four, five or six times that figure.

Examples: Why Your Business Income Figures Matter

Example 1: Sole trader with changing profits

A self-employed electrician records £42,000 profit in one completed tax year and £50,000 in the next. The simple two-year average is £46,000.

One lender may use an average of verified profit, while another may give more weight to the most recent year or use a cautious figure if income is falling. This example does not establish the income any particular lender would accept.

Example 2: Limited company director

A company director earns a £12,570 salary and £30,000 in dividends, totalling £42,570 in personal earnings. The company also retains profits.

A lender using salary and dividends could assess the personal earnings figure, subject to its policy. Another lender may consider eligible company profits instead. Retained profit should not simply be added to salary and dividends without understanding the lender’s calculation and avoiding double-counting.

Example 3: Contractor with a day rate

An IT contractor has a contract paying £400 per day. At 220 working days, the simple annualised contract value is £88,000.

That is not necessarily the applicant’s qualifying mortgage income. A lender may use accounts-based income instead, or apply its own permitted contract-day calculation, assumptions about working weeks and checks on contract continuity.

Key distinction: annualised contract value, company turnover, net trading profit and money available for mortgage repayments are different figures. Your lender’s accepted income calculation is what matters.

Deposit Requirements and Other Mortgage Costs

A larger deposit can reduce the loan-to-value ratio and may open access to a wider product range. However, self-employed applicants do not automatically need a larger deposit solely because of their employment status.

5% Example deposit for a 95% LTV product, if eligible.
10% Example deposit for a 90% LTV mortgage.
20% Example deposit for an 80% LTV mortgage.

Example on a £250,000 property

5% deposit: £12,500 Illustrative mortgage required: £237,500.
10% deposit: £25,000 Illustrative mortgage required: £225,000.
20% deposit: £50,000 Illustrative mortgage required: £200,000.

Budget separately for property taxes applicable to the purchase, solicitor or conveyancing fees, any mortgage product fee, valuation costs, surveys, removals, insurance and other moving expenses.

Stamp Duty Land Tax generally applies in England and Northern Ireland where relevant. Scotland has Land and Buildings Transaction Tax, while Wales has Land Transaction Tax. Amounts and exemptions depend on the property and buyer circumstances.

Self-employed cash-flow tip: keep business tax reserves, VAT obligations where relevant and essential working capital separate from your proposed house deposit. The lender may ask for evidence showing the deposit is genuinely available and its source is acceptable.

Which Building Societies Should Self-Employed Borrowers Check?

Different building societies have different lending approaches. The examples below are starting points for checking current criteria, not a ranking or claim that every lender will accept one year’s accounts, retained profits or every type of contract.

Leeds Building Society

Its intermediary mortgage information specifically describes options for self-employed applicants, including its Income Plus range subject to eligibility.

Building Society or Bank: Is One Better for Self-Employed Mortgages?

Neither is automatically better. The useful comparison is between individual mortgage products and lending criteria, not simply the type of financial institution.

What may favour a building society

  • Different approaches to income verification.
  • Specialist or intermediary-led mortgage options.
  • Potential consideration of unusual but sustainable income patterns.
  • Products suited to certain borrower circumstances.

What should still be compared

  • Initial interest rate and APRC.
  • Product and valuation fees.
  • Maximum loan-to-value ratio.
  • Early Repayment Charges.
  • Income calculation and affordability.
  • Mortgage term and repayment flexibility.

A building society may decline an application another bank accepts, and the reverse can also happen. The actual underwriting policy matters more than a general claim about flexible lending.

How to Apply for a Self-Employed Building Society Mortgage

Prepare the income evidence before submitting the application. This is especially important if your latest figures are different from the previous year or your company structure has changed.

  1. Identify your income type. Decide whether you are applying as a sole trader, director, partner or contractor, and gather the records matching that structure.
  2. Review your financial history. Check the most recent accounts, tax returns, outstanding borrowing and regular expenditure.
  3. Check deposit and affordability. Use conservative income assumptions and leave adequate money for buying costs and business obligations.
  4. Compare lender criteria. Find lenders that can consider your trading history, income structure and proposed property.
  5. Consider qualified advice. An authorised mortgage adviser with self-employed lending experience may help identify appropriate lenders and application routes.
  6. Seek a Decision in Principle. Check whether the lender uses a soft or hard credit search and whether income has been fully assessed at this stage.
  7. Submit the full application. Provide the requested tax calculations, accounts, statements and explanations accurately.
  8. Respond to underwriting questions. The lender may ask about business profit changes, contracts, deposits or credit commitments.
  9. Review the formal mortgage offer. Check the rate, fees, term, repayment amounts, restrictions and conditions before proceeding to completion.
Decision in Principle is not final approval: a DIP or AIP is an initial lending indication. The full application, property valuation, documentary evidence and underwriting must still be satisfactory.

Common Reasons Self-Employed Mortgage Applications Become Difficult

Profit has fallen A lender may question whether the decline is temporary or indicates a sustained fall in income. Prepare an evidence-based explanation.
Low declared income A high turnover or healthy business bank balance may not compensate for low qualifying profits under the lender’s policy.
Short trading history Some lenders may decline before considering the rest of the application. Check their minimum trading period first.
Outstanding tax debt Unpaid liabilities can affect cash flow and the lender’s assessment. Disclose and explain relevant payment arrangements.
Unclear deposit source Transfers from business accounts, gifts or substantial recent deposits may need supporting documents.
Inconsistent paperwork Differences between accounts, tax calculations and bank statements can prompt further checks.
Recent business change Moving from sole trader to limited company can complicate evidence of continuous trading and comparable income.
Contract ending soon The lender may request evidence of renewal, continuing work or previous contracts.

If your application has already been declined

Ask what caused the decision before submitting another application. The issue could be income evidence, policy eligibility, credit history, affordability, deposit or property valuation.

A decline by one lender does not prove all lenders will refuse. However, repeated applications without understanding the problem may create unnecessary hard searches and will not correct an underlying affordability issue.

How to Strengthen Your Mortgage Application

Keep accounts and tax returns up to date.
Make sure tax computations match submitted returns.
Maintain clear personal and business records.
Avoid unexplained large transactions.
Check your credit reports for errors.
Reduce unnecessary personal borrowing where feasible.
Keep deposit funds and their source documented.
Prepare evidence supporting ongoing business income.
Do not distort your accounts to obtain a mortgage. Declare income accurately and take independent accountancy or tax advice before changing how you draw money from your business. A mortgage application must reflect genuine financial circumstances.

2026 Mortgage Regulation: What Self-Employed Borrowers Should Know

In June 2026, the Financial Conduct Authority announced proposals aimed at improving mortgage access, including possible flexibility for borrowers with variable incomes such as the self-employed.

These proposals do not mean every lender must accept one year’s accounts, ignore affordability tests or provide a higher mortgage automatically. Borrowers still need to meet applicable lender and regulatory requirements.

Should You Use a Mortgage Broker?

A mortgage adviser can be useful when your accounts show fluctuating profit, you have a limited company, you are paid through contracts or you need help finding a lender that accepts your exact evidence.

An adviser should explain the lenders they can access, how they are paid, what advice fee may apply and why a recommended mortgage is suitable for your circumstances.

Consider a broker when

  • You have one year’s accounts.
  • Your profits have changed substantially.
  • You retain profits within a limited company.
  • You have several income sources.
  • Your contract arrangement is unusual.
  • Another lender has already declined the case.

Questions to ask the adviser

  • Are you FCA-authorised or acting for an authorised firm?
  • Do you consider products across the market or only a limited panel?
  • Which self-employed income calculation applies?
  • What broker fee will I pay?
  • What will happen if the application is declined?
  • How will you protect my tax and banking documents?

Self-Employed Building Society Mortgage FAQs

1. Can I get a building society mortgage if I am self-employed?

Yes. Building societies can lend to eligible self-employed borrowers. They normally examine verified business income, trading history, deposit, credit commitments and household affordability before deciding whether to offer a mortgage.

2. How many years of accounts do I need?

Two years is a common starting point, and some lenders may request three. Certain lenders consider applicants with a shorter history, but the evidence and other eligibility requirements can be stricter.

3. Can I get a mortgage with one year’s accounts?

Possibly. Some lenders may consider one year’s accounts depending on trading continuity, income sustainability, experience, credit history and deposit. The lender’s current criteria should be checked before applying.

4. Do building societies use self-employed turnover or profit?

They generally assess eligible verified income rather than business turnover alone. Sole traders may be assessed on net trading profit, while company directors may be assessed using salary, dividends or other acceptable income according to lender policy.

5. Can a limited company director use retained profits?

Some lenders may consider an attributable share of company profits, subject to ownership, accounts, business sustainability and their current lending criteria. Other lenders primarily consider salary and dividends. Retained profit cannot automatically be added to personal income.

6. What is an SA302 for a mortgage?

An SA302 is an HMRC tax calculation showing information used to calculate an individual’s Self Assessment tax liability. Mortgage lenders may request it together with the corresponding HMRC tax year overview.

7. Can a contractor get a mortgage using a day rate?

Some lenders have contractor-income assessment methods that can consider a day rate, contract duration and work history. Others use business accounts or tax-return income. A contractor’s annualised contract value is not automatically their accepted mortgage income.

8. Do self-employed borrowers need a larger deposit?

Not necessarily. Deposit requirements depend on the lender, product, property, affordability and credit assessment. Some products permit smaller deposits for eligible applicants, but individual criteria still apply.

9. Can I get a mortgage if my latest business profit has fallen?

Possibly, but the lender may investigate why profit has fallen and whether the lower figure is likely to continue. Different lenders use different methods for variable income, so an accurate explanation with supporting accounts can be important.

10. Is a mortgage broker useful for a self-employed application?

An appropriately authorised adviser can be helpful when income is complex, accounts are limited or previous applications have been unsuccessful. Check the adviser’s FCA status, lender panel, fees and recommended application route before proceeding.
