Your £200,000 Foreign Salary Might Only Count as £160,000 (UK Mortgage Rules 2026)

Recognised Income Is Not Gross Income

When most expats look at affordability calculators, they enter their gross salary and expect the result to be roughly accurate. For a UK resident borrower, that is a fair approximation. For a UK expat borrower, it is rarely the right starting point.

UK lenders treat foreign-currency income, bonus pay, commission, allowance pay, self-employed earnings, rental income, investment income and pension income differently from a uniform GBP salary. Each is weighted, discounted or excluded according to the lender's published policy and underwriting practice.

The figure that actually drives the affordability calculation is recognised income. That is the figure left after the lender has applied its currency haircut, its bonus discount, its allowance exclusion and any other adjustments. For a typical expat case, the gap between gross income and recognised income is 10-30%. On larger or more complex profiles it can be more.

This article walks through how UK lenders actually assess foreign income in 2026, so the borrower can model their own recognised income before any application is submitted. The structure mirrors the order in which the underwriter applies it:

• Currency: which currencies the lender will accept and at what discount
• Income type: how basic salary, bonus, commission and allowances are weighted
• Self-employed and contractor income
• Limited company director income
• Rental, investment and pension income
• The realistic gap between gross and recognised
• How recognised income runs through affordability stress tests

The goal is to remove the surprise. Borrowers who walk into an application with a pre-modelled recognised income figure tend to land much closer to their target loan amount than borrowers who walk in with the gross figure and discover the gap at the underwriter's desk.

Currency Tiers and the Haircut Policy

Lenders apply a currency haircut for one reason: foreign-currency income carries FX risk that the lender has to price in. The policy varies by lender but the broad pattern across active expat lenders in 2026 is consistent.

{{INSET-CODE-5}}

Within a tier, lender practice varies. Some lenders apply a flat 25% haircut on all foreign income. Others apply a 0% haircut on tier-1 currencies and accept the income at face value. Specialist lenders typically sit somewhere in between, with country-specific adjustments.

Three practical implications:

• Tier-1 income borrowers (USD, EUR) should aim for lenders with 0-10% haircut policies; the rate spread can be material
• AED and HKD borrowers benefit from the USD peg; lenders treat the FX risk as comparable to USD
• Emerging market currency borrowers may struggle to find a lender that accepts the income at all, regardless of how strong the gross figure is

The haircut applies to the gross GBP-equivalent figure, so the borrower should also factor in the prevailing exchange rate at the time of application. A bonus paid in EUR last year and converted to GBP at last year's rate may be assessed at a different sterling figure today.

A worked example helps. A borrower earning $300,000 in USD with a high street lender applying a 25% haircut sees recognised income of $225,000 GBP-equivalent. The same borrower at a specialist lender applying a 10% haircut sees $270,000. On a 4.5x multiple, the difference between the two lenders is roughly £150,000 of borrowing capacity, on the same gross income. The lender selection decision is therefore inseparable from the income assessment decision; the two need to be made together rather than in sequence.

Lender haircut policies also evolve. In 2026 several specialist lenders have softened their tier-2 policies as the FX environment has steadied, while a small number of mainstream lenders have tightened tier-3 policies in response to volatility in specific markets. The right answer for any borrower depends on the lender's policy at the time of application, not the policy that was in force a year earlier.

Income Type: Basic Salary vs Bonus vs Commission vs Allowance

On top of the currency haircut, lenders weight different income types differently. This is where most of the gap between gross and recognised tends to appear.

{{INSET-CODE-6}}

A worked example. A borrower earning £200,000 GBP equivalent in EUR, with a £40,000 bonus and a £25,000 housing allowance, may end up assessed at:

• Basic salary: £200,000 less 10% currency haircut = £180,000
• Bonus: £40,000 average × 75% bonus weighting = £30,000
• Housing allowance: contractually fixed, included at 100% = £25,000
• Recognised income total: £235,000

If the same borrower had a discretionary housing allowance, that £25,000 would drop out and the recognised figure becomes £210,000 instead of £235,000. The same gross income, two different recognised numbers, and a meaningful difference in affordability.

The contract wording matters more than borrowers usually expect. Lenders look closely at how each pay element is described in the employment contract. Phrases like "discretionary", "reviewable" or "subject to performance" tend to push the underwriter toward exclusion. Phrases like "contractually fixed", "guaranteed", or "automatic uplift" push toward inclusion. Where the contract is unclear, an employer's letter clarifying the treatment can sometimes help, but it does not override the contract itself.

Share-based pay deserves special attention for borrowers in financial services or technology. Lenders treat RSUs, performance shares and option grants differently. A vested RSU that has been sold and converted to cash in a regular pattern over two to three years may be partially included; an unvested grant that has not yet been realised is almost always excluded. The same underlying compensation can therefore be highly material or completely invisible depending on lifecycle stage.

{{INSET-CODE-1}}

Self-Employed and Contractor Income

Self-employed and contractor borrowers face a different set of rules. The basic principle is that the lender wants to see net profit, not turnover, and needs evidence over multiple years to confirm sustainability.

The standard documentation:

• Two to three years of certified accounts (some specialist lenders accept one year for strong cases)
• An accountant's letter confirming current trading status and profit
• SA302 self-assessment tax calculations from HMRC for the same period (or country equivalent)
• A current contract or evidence of forward work, particularly for contractors
• Three to six months of personal and business bank statements

The figure used:

• Sole traders: net profit (after expenses, before tax)
• Partnerships: share of partnership profit
• Limited company contractors: salary plus dividend, or salary plus net profit (depending on lender)
• Day-rate contractors: typically annualised at 46-48 weeks of working time

For contractor borrowers paid in foreign currency, both the day rate and the annualised income are run through the currency haircut. A US-based contractor on a $1,000 day rate, working 46 weeks, has a gross annualised income of $460,000. After conversion to GBP and a 10-15% USD haircut, recognised income lands closer to £305,000-£325,000 at typical 2026 exchange rates. That gap matters more for contractors than for employed borrowers because the income is already weighted by the lender's view of contract continuity.

The variance across lenders is also wider than for employed borrowers. Skipton International, HSBC Expat and specialist lenders take very different views on self-employed expat profiles. The right lender for a self-employed expat with two years of accounts is rarely the same as for a self-employed expat with five.

A few additional details that often catch self-employed expat borrowers off-guard:

• Recently incorporated companies (less than two years trading) usually require a specialist lender even if the underlying business is mature
• A business that has switched accounting treatment in the last two years (sole trader to limited company, or single-director to multi-director) often resets the lender's evidence window
• Profit volatility year-on-year reduces the figure the lender will use; some lenders take the lower of two years rather than an average
• Foreign accounting standards (IFRS, US GAAP, country GAAP) are usually accepted with the accountant's letter cross-referencing the equivalent UK numbers
• Where the borrower is a director and shareholder of the same UK SPV being used to buy the property, the income from the SPV cannot be double-counted as both director income and rental income

Limited Company Directors

Limited company directors sit somewhere between employed and self-employed in lender treatment. The lender usually assesses one of two figures:

• Salary plus dividend: the borrower's drawn income from the company
• Salary plus net profit: the borrower's salary plus their share of company net profit (used when retained earnings are significant)

Directors with significant retained earnings often benefit from the second approach because it reflects economic income rather than just drawn income. Specialist lenders are more likely to accept the salary-plus-net-profit basis; mainstream lenders often default to salary-plus-dividend.

Documentation typically required:

• Two to three years of company accounts
• An accountant's letter confirming current trading status and director's drawings
• Personal SA302s showing salary and dividend declared
• Three to six months of personal and business bank statements

For expat directors of a company in the country of residence, the same currency haircut applies as for any other foreign income. The directorship of a UK limited company while living overseas is also possible and creates its own treatment, particularly where the company is the SPV used for UK property. SPV-side details sit in the dedicated guide to UK expat buy-to-let mortgages.

Rental, Investment and Pension Income

For borrowers whose income comes wholly or partly from non-employment sources, lenders apply a third set of rules.

{{INSET-CODE-7}}

Rental income is the most common addition to recognised income for expat borrowers. The 75% rule reflects the lender's allowance for void periods, repairs, agent fees and other costs. Where the borrower is also a portfolio landlord (4+ mortgaged BTL), the rental income is assessed at the portfolio level under the PRA's SS13/16 framework, with the underlying ICR test applied to the entire portfolio rather than just the new property. The PRA's January 2026 update to SS13/16 (published alongside Policy Statement PS1/26) reinforces this portfolio-level approach, with full implementation effective from January 2027.

Investment income is more selective. A borrower with five years of stable dividend history from a diversified portfolio may have it weighted favourably. A borrower with a single year of dividend income from a recently established holding company is less likely to be credited. Investment income held inside an ISA or pension wrapper is sometimes treated differently from investment income held in a general investment account; the wrapper structure can affect lender appetite even where the underlying assets are identical.

Pension income is straightforward once in payment but can become a complication for borrowers in early retirement who plan to draw down later. Lenders rarely credit expected future pension income. The borrower who is approaching retirement and plans to use a pension lump sum or an annuity to support the mortgage usually needs to demonstrate either (a) the pension is already in payment or (b) sufficient existing income or assets to bridge the gap.

The Realistic Gap Between Gross and Recognised

Pulling these rules together, the realistic gap between gross income and recognised income for typical expat profiles in 2026:

{{INSET-CODE-8}}

The table is illustrative; the precise number for any individual case depends on lender choice, currency, income mix and documentation quality. The point is that the gross-to-recognised gap is rarely zero and frequently 20% or more.

A borrower modelling £200,000 of gross income and assuming a £900,000 loan based on a 4.5x multiple may find the real recognised income is £160,000, the realistic affordability is closer to £700,000, and the gap of £200,000 against the borrower's expected number is what triggers the disappointment at affordability stage.

{{INSET-CODE-3}}

Recognised Income Through the Stress Test

Once recognised income is calculated, it runs through the lender's affordability stress test. For residential cases that typically means a stressed rate of 8-9% applied to the requested loan term, with affordability tested against the stressed payment. For buy-to-let cases the test is on rental coverage rather than personal income, with 125% interest cover for limited company applicants and 145% for higher-rate personal borrowers, at stress rates of 5.5-7%.

For a borrower with £200,000 of recognised income and a £75,000 partner income, the typical residential affordability calculation might produce:

• Joint recognised income: £275,000
• Stressed payment ceiling: 35-40% of gross monthly income
• Maximum stressed payment: £8,000-£9,200 per month
• Maximum loan at 8.5% stress over 25 years: £1.0m-£1.2m

The practical takeaway: the affordability number is built on recognised income, not gross. Borrowers who confirm recognised income upfront know what loan size they are realistically working with and can pick a property accordingly. Borrowers who do not often pick a property based on gross income, find affordability falls short at the underwriter's desk and have to renegotiate or renegotiate at exchange. For more detail on how the underwriter then verifies all of this, see the dedicated guide to what UK lenders look for when approving expat mortgages.

How to Model Your Own Recognised Income

One of the strongest pieces of preparation a borrower can do before any application is to model their own recognised income, the way the lender will, before submission. The exercise takes about an hour and follows a simple sequence:

• Convert all income to GBP at the current rate
• Apply the relevant currency haircut by tier
• For bonus and commission, take the three-year average and weight at 50-75%
• For allowance pay, exclude items the lender will not credit (school fees, COL, discretionary)
• For self-employed income, use net profit, not turnover, with two to three years of accounts
• For rental income, take 75% of gross
• For investment and pension income, apply lender treatment depending on history and source
• Sum the result

Compare the result to the gross figure. The gap is the borrower's realistic affordability margin.

A practical refinement: build two recognised income figures, not one. Build a conservative figure using the lender most likely to apply the toughest haircut, and an optimistic figure using the lender most likely to apply the softest. The realistic affordability range usually sits between the two. This range, rather than a single number, is what the borrower should be working with when choosing a property.

It is also worth modelling the recognised income through the next two years of likely changes. If the borrower expects a salary increase, a bonus reset or a transition to self-employment, those moves change the recognised figure. A two-year look-forward saves the surprise of finding the file looks weaker at the next refinance than it did at the original purchase.

This is also where the eligibility filter that confirms which lenders will look at your case becomes the natural next step, because lender choice directly affects the haircut policy applied to the same income.

Beyond the Mortgage: Where Skybound's Wider Service Suite Fits In

Modelling recognised income answers one question: how much a UK lender will count. But the same income that drives the mortgage also sits at the centre of a wider financial position, and Skybound's proposition is that those can be handled together, in house, if the client wants that.

Around the income that supports a UK mortgage, a cross-border borrower usually has:

• Currency strategy, since income earned in one currency funds a mortgage payable in another
• Tax coordination across the UK and the country of residence, on employment, investment and rental income
• Insurance and protection, so the income that supports the mortgage is itself protected
• Retirement planning, including how current income converts into future pension provision
• Legacy and estate planning, since UK situs property sits within UK Inheritance Tax

None of this is required to get a UK mortgage. The mortgage can be arranged entirely on its own, and many borrowers will want only that. The point is that, for a client who would rather not assemble a separate specialist for each piece, Skybound can fold the mortgage into a single coordinated plan built around the same income picture. It is an option, not a precondition. Income protection in particular is worth a thought here: the recognised income that secures the mortgage is also the income the household depends on, and a borrower modelling affordability is well placed to consider how that income is safeguarded at the same time.

Final Takeaway

How foreign income is assessed for UK mortgages is not about:

• Entering gross income into a calculator and trusting the answer
• Assuming all currencies are accepted at face value
• Treating bonus, commission and allowance as equivalent to basic salary
• Picking a property before the recognised income figure is known

It is about:

• Modelling recognised income before any application is submitted
• Picking the lender whose haircut policy matches your income mix
• Documenting bonus and commission history over two to three years
• Confirming which allowance components are contractual rather than discretionary
• Coordinating recognised income with deposit, currency and product decisions

Most expats only realise the gap between gross and recognised at the affordability stage, when the underwriter pushes back. Those who model it first usually land closer to the loan amount they actually want, with fewer surprises along the way.
