One of the most common questions we receive from UK expats is whether foreign currency income counts for a UK mortgage. The short answer is yes – specialist lenders are set up to accept income in most major currencies. But the way it is assessed varies by lender and currency, and getting the right lender match makes a significant difference to your borrowing capacity. For more information, see HMRC guidance for overseas income.
Which Foreign Currencies Are Accepted?
Specialist expat lenders accept income in a wide range of currencies, including:
- USD (US dollars) – widely accepted, though some lender restrictions apply for US-based applicants
- AED (UAE dirhams) – very well accepted
- CHF (Swiss francs) – well accepted; Swiss salaries are typically high and translate favourably
- CAD (Canadian dollars) – well accepted with no significant lender restrictions
- SGD (Singapore dollars) – accepted; Singapore-based professionals often have strong income profiles
- AUD (Australian dollars) – well accepted
- HKD (Hong Kong dollars) – accepted
- EUR (euros) – well accepted across most specialist lenders
Other currencies are also considered on a case-by-case basis. Contact us to discuss your specific currency situation.
How Is Foreign Currency Income Converted?
Lenders convert your overseas income to sterling using a published exchange rate – typically a recent spot rate or a short-term average. Most lenders apply a currency buffer of between 5-15% to account for exchange rate movement over the mortgage term. This buffer slightly reduces your assessed income in sterling terms.
The size of the buffer applied depends on the volatility of the currency. Stable, pegged currencies like AED and HKD attract smaller buffers. More volatile currencies like ZAR attract larger ones.
Tax-Free Income: Does It Count in Full?
Yes. If you earn a tax-free salary – common in the UAE and other Gulf countries – most specialist lenders will assess your full gross income rather than a net-of-tax figure. This is a meaningful advantage: a tax-free salary of 100,000 AED is assessed at its full value, whereas an equivalent UK salary would be reduced by income tax before being used in the affordability calculation.
Bonuses and Variable Pay
Many expat professionals – particularly those in banking, finance, and technology – receive significant bonuses or commission on top of their base salary. Some specialist lenders will factor in variable income using a 2-3 year average. Others will only use base salary. We know which lenders take the most generous view of variable pay, which can significantly increase your borrowing capacity.
What Documents Do You Need?
- 3-6 months of payslips in your local currency
- Employment contract or letter of employment confirming salary
- 3-6 months of bank statements showing salary credits
- For self-employed: 2-3 years of overseas tax returns or certified accounts

Frequently Asked Questions
Can I get a UK mortgage if I earn in a foreign currency?
Yes. Specialist expat lenders accept income in most major currencies. Your earnings are converted to sterling at a prevailing rate for affordability assessment purposes.
Does the currency I earn in affect how much I can borrow?
Yes, slightly. Lenders apply a currency buffer that varies by currency volatility. More stable currencies like AED, HKD, and EUR attract smaller buffers and therefore result in a higher sterling-equivalent income assessment.
My salary is tax-free – will lenders use the full amount?
Yes. Most specialist lenders assess tax-free overseas income at its full gross value, which is a genuine advantage for expats based in the UAE and other tax-free jurisdictions.
Can I include my bonus in the mortgage assessment?
Some lenders will include a proportion of regular bonus income, typically using a 2-3 year average. This varies by lender – we will identify those who take the most favourable view of your income structure.
