Can a British expat get a UK mortgage, and what do lenders look at?
Yes. UK lenders and private banks lend to British expats living and working abroad. They assess your foreign currency income (usually with a 15–30% adjustment for exchange-rate movement), a deposit of typically 25–40%, evidence of your residency abroad and a clear paper trail for the deposit funds.
- Income in USD, EUR, CHF, AED and SAR is the most widely accepted; other currencies are handled by a smaller panel.
- Deposit funds must be traceable, and countries with exchange controls need extra evidence.
- Local residency and tax documents stand in for UK paperwork.
- A UK credit history helps but is not essential.
Key takeaways
- Most UK lenders accept major foreign currencies but discount the converted income by 15–30% before calculating affordability.
- Overseas applicants typically need a 25–40% deposit, with the higher end for less widely accepted currencies.
- Lenders need a clear source-of-funds trail for the deposit — especially where exchange controls apply, such as South Africa and China.
- Residency is evidenced with local documents: a residence permit or ID card, address registration and local tax records.
- Certified copies usually come from a local notary or lawyer; some countries also need an apostille or legalisation.
Currency conversion and foreign income
A UK mortgage is repaid in sterling, so lenders convert your foreign income into pounds and then usually apply a "haircut" — commonly 15–30% — to allow for exchange-rate movement before running affordability. Pegged currencies such as the US-dollar-linked Gulf currencies often attract a smaller adjustment.
Across the countries we cover, lender appetite for local income falls into three broad groups:
- Widely accepted: EUR (Spain), EUR (France), EUR (Ireland), CHF (Switzerland), EUR (Germany), EUR (Netherlands).
- Accepted by a selection of lenders: QAR (Qatar), KWD (Kuwait), BHD (Bahrain), OMR (Oman).
- Accepted by a small number of specialist lenders: ZAR (South Africa), JPY (Japan), CNY (China).
Where income is less widely accepted, holding part of your income or assets in GBP, USD or EUR can widen the options. See our guide to how UK lenders assess foreign income for the full detail.
Deposit rules and source of funds
As an indicative working assumption, overseas applicants often need a 25–40% deposit. The exact figure depends on residency, income, property use and lender criteria, and sits at the higher end where the currency is less widely accepted.
Just as important as the size of the deposit is proving where it came from. Lenders ask for bank statements and a clear source-of-funds trail, and two countries need particular care:
- South Africa: Transfers above R1 million per calendar year out of South Africa need SARS Approval for International Transfer (AIT) — keep the AIT PIN and approval record.
- China: Keep bank records showing how deposit funds left China within the annual foreign-exchange allowance or other lawful routes.
- Switzerland: Pillar 3a or pension assets are not usually accepted as deposit unless released.
Gifted deposits from close family are often acceptable with a gift letter and the donor's own source-of-funds evidence.
Residency evidence by country
Lenders need to confirm where you live and that you are there lawfully. The usual evidence is a residence permit or national ID card, proof of address and local tax records. What that looks like varies by country:
- Spain: TIE residency card or NIE certificate; tax evidence: Spanish IRPF (Modelo 100) tax returns. Full Spain checklist
- France: titre de séjour or proof of French address; tax evidence: French avis d'imposition (tax notices). Full France checklist
- Ireland: proof of Irish address; tax evidence: Revenue employment detail summaries or Form 11 returns. Full Ireland checklist
- Switzerland: Swiss residence permit (B or C); tax evidence: Swiss tax assessments or Lohnausweis salary certificates. Full Switzerland checklist
- Germany: Aufenthaltstitel or Meldebescheinigung (address registration); tax evidence: German Lohnsteuerbescheinigung and Steuerbescheid. Full Germany checklist
- Netherlands: BRP municipal registration extract; tax evidence: Dutch jaaropgaaf and belastingaanslag. Full Netherlands checklist
- Qatar: Qatar ID (residence permit); tax evidence: salary certificates (Qatar has no personal income tax). Full Qatar checklist
- Kuwait: Kuwait Civil ID; tax evidence: salary certificates (Kuwait has no personal income tax). Full Kuwait checklist
- Bahrain: Bahrain CPR card; tax evidence: salary certificates (Bahrain has no personal income tax). Full Bahrain checklist
- Oman: Oman resident card; tax evidence: salary certificates and payslips. Full Oman checklist
- South Africa: South African ID or proof of address; tax evidence: SARS IRP5 certificates and ITA34 assessments. Full South Africa checklist
- Japan: Japanese residence card (zairyu card); tax evidence: gensen choshuhyo withholding slips. Full Japan checklist
- China: Chinese residence permit or proof of address; tax evidence: Chinese individual income tax records. Full China checklist
Living abroad does not by itself make you non-resident for every purpose — the UK non-resident stamp duty surcharge uses its own residence test, so ask your UK solicitor to confirm the position before exchange.
Certified copies, apostilles and translation
UK lenders rarely accept ordinary photocopies of overseas documents. Copies are usually certified by a local notary or lawyer, and some countries add an apostille or legalisation step. The detail by country:
- Spain: a Spanish notario or lawyer. Spanish documents may need certified English translation.
- France: a French notaire or avocat. French documents commonly need certified English translation.
- Ireland: an Irish solicitor, commissioner for oaths or notary public.
- Switzerland: a Swiss notary. German, French or Italian documents may need certified translation.
- Germany: a German Notar. German documents commonly need certified English translation.
- Netherlands: a Dutch notaris. Dutch documents may need certified English translation.
- Qatar: a Qatari notary or lawyer, sometimes with Ministry of Foreign Affairs attestation (Qatar is not an Apostille Convention member, so legalisation rather than an apostille applies).
- Kuwait: a Kuwaiti notary or lawyer, sometimes with Ministry of Foreign Affairs attestation (Kuwait is not an Apostille Convention member, so legalisation rather than an apostille applies).
- Bahrain: a Bahraini notary or lawyer, with an apostille from the Ministry of Foreign Affairs if requested.
- Oman: an Omani notary or lawyer, with an apostille from the Ministry of Foreign Affairs if requested.
- South Africa: a South African commissioner of oaths or notary, with an apostille if requested.
- Japan: a Japanese notary (koshonin), with an apostille if requested. Japanese documents normally need certified English translation.
- China: a Chinese notary public office, with an apostille if requested (China joined the Apostille Convention in November 2023). Chinese documents normally need certified English translation.
Confirm the exact certification standard with the lender before paying for it — requirements differ, and getting it right first time avoids weeks of delay.

Frequently asked
Questions from readers
Which foreign currencies do UK mortgage lenders accept?
USD, EUR, CHF, AED and SAR are the most widely accepted. QAR, KWD, BHD and OMR are handled by a narrower panel, and ZAR, JPY and CNY by a small number of specialist lenders and private banks.
How do lenders convert my foreign income?
Income is converted into pounds and then usually discounted by 15–30% — a 'currency haircut' — before standard income multiples are applied. Pegged currencies often attract a smaller adjustment.
How much deposit does a British expat need for a UK mortgage?
As an indicative working assumption, 25–40% is common for overseas applicants, with the higher end for less widely accepted currencies or more complex income. Stronger cases can sometimes go lower.
Can I move my deposit out of a country with exchange controls?
Yes, but the paper trail matters. Transfers above R1 million a year out of South Africa need SARS Approval for International Transfer, and funds leaving China must move within the annual foreign-exchange allowance or other lawful routes — keep the records.
What counts as proof of residency abroad?
Usually a residence permit or national ID card (for example a Spanish TIE, a Qatari Qatar ID or a Japanese residence card), plus proof of address such as a registration certificate, utility bill or bank statement.
Do I need a UK credit history?
Not necessarily. Lenders experienced with overseas applicants can assess verified income, assets and banking history in your country of residence — for example a SCHUFA report in Germany or a BKR report in the Netherlands — instead of a UK credit file.
Who can certify my documents?
Usually a local notary or lawyer. Some countries add an apostille or legalisation step — Qatar and Kuwait use legalisation rather than apostilles, while China joined the Apostille Convention in November 2023. Confirm the lender's exact standard first.
Will the UK non-resident stamp duty surcharge apply?
It can apply in England and Northern Ireland if the residence test is not met, and higher additional-property rates may also apply. Your UK solicitor should confirm the position before exchange.
How long does a UK mortgage application take from abroad?
A well-prepared overseas application often takes around six to ten weeks, depending on valuation, document certification and international identity checks.
Do Gulf allowances and end-of-service benefits count as income?
Contractual allowances such as housing and schooling are often counted where they appear in the employment contract. End-of-service gratuity should be shown in the contract and is usually treated as an asset rather than income.
