A UK mortgage using income earned outside the UK.

Overseas employment income is income paid by an employer based outside the UK. This differs from foreign currency income — which is about the denomination of income — though the two often go together.

Most mainstream UK lenders will not accept overseas employment income at all, or will only accept it where it supplements a primary UK income that already meets their affordability threshold. The specialist lender panel is more flexible, but lenders within it have varying rules on which countries and employer types they will recognise, what proportion of overseas income they will use and what evidence they require.

Employer type and country of operation matter considerably. Income from a major multinational — particularly a US, European or Gulf employer — is generally viewed more favourably than income from a small business in a less economically stable country. Income from a UK subsidiary of an overseas company (where the applicant is technically employed by a UK entity even if most of the business is outside the UK) is treated differently again — often as standard UK employment.

Employment type is also relevant. Permanent salaried employment from an overseas employer is the strongest position; fixed-term, contracting or self-employment arrangements with overseas clients are assessed more conservatively. Lenders will want to see the employment contract alongside recent payslips — and if payslips are in a foreign language, may require a certified translation.

Length of employment history helps. A short period with an overseas employer, or a recent switch from UK to overseas employment, will receive more scrutiny than a stable, long- running overseas employment history. Two or more years with the same employer tends to give lenders the most confidence.

A haircut is the discount a lender applies to income before using it in an affordability calculation. Where overseas income is accepted at all, lenders rarely use 100% of it. Common haircut levels are 75–80% of the gross income figure — meaning a £60,000 overseas salary might be assessed as £45,000– £48,000 for affordability purposes. The haircut reflects the lender’s uncertainty about currency stability, exchange rate movement and the additional verification difficulty of overseas income.

Currency pegged to USD — such as the UAE dirham or Saudi riyal — is often accepted with a smaller haircut than genuinely floating currencies, because the exchange rate risk is lower. Sterling income from an overseas employer (where the pay is actually received in GBP to a UK bank account) is often treated as standard UK income for this purpose.
