Start With a UK-Based Broker
The single most important decision is choosing a broker who handles expat remortgages every week. Generic UK mortgage brokers often have limited exposure to expat cases, use incorrect lender criteria, and can waste weeks applying to lenders who will decline. Look for:
- Firms that specifically market "expat mortgage broker" services
- Authorisation by the FCA (check the Financial Services Register)
- Experience with your specific country of residence
- Familiarity with the lender panel (Skipton International, Barclays International, etc.)
- Ability to communicate in your time zone — many have international teams
- Transparent fee structure (expat brokers typically charge £495-£1,500)
Most initial consultations are free and can be done over video call.
Paperwork Logistics
Document collection is the biggest time cost of a remortgage from abroad. Practical advice:
- Scan early and often — digitise every financial document as it arrives, stored securely in cloud storage. Two years of tax returns, six months of payslips, twelve months of bank statements
- Obtain a UK Voter's registration statement if possible — Overseas Voter registration exists for up to 15 years after leaving the UK. It's useful for some lenders as address continuity
- Keep a UK mailing address — a family member or mail forwarding service in the UK is invaluable for receiving lender correspondence
- Request original documents where needed — some lenders still require originals. Factor in international courier costs and times
- Employer letter in English — your broker will provide a template. Ensure your HR department stamps and dates the original
- Translation where needed — documents in non-English languages need certified translation, typically £15-£40 per page
Keep a single master folder labelled "UK remortgage" with sub-folders for income, property, personal ID, and correspondence. This speeds up every stage.
Apostille and Notarisation Rules
Some documents for UK property transactions need apostille certification under the Hague Apostille Convention 1961. An apostille is a formal stamp confirming the authenticity of a signature or notarisation.
Typical documents requiring apostille:
- Power of attorney for overseas signatures
- Notarised copies of passports
- Proof of overseas marriage or divorce where relevant to title
Process in most Hague Convention countries:
- Visit a local notary public
- Notary witnesses your signature or certifies a copy
- Notarised document is sent to the designated competent authority (Foreign Ministry, State Department, etc.) for apostille
- Completed apostille returned and couriered to UK
Cost: typically £50-£200 per document depending on country. Time: 3-10 working days. Non-Hague countries (including UAE until 2021 and still some others) may require legalisation via UK embassy, which takes longer.
Remote Signing Options
For non-deed documents, e-signature platforms like DocuSign, Adobe Sign and HelloSign are now widely accepted by UK lenders and solicitors. These work well for:
- Mortgage application forms
- Broker fee agreements
- Solicitor client care letters
- Declarations and certifications of identity
For mortgage deeds and certain property transfer documents, UK law has traditionally required wet-ink signatures witnessed by a person in the signer's physical presence. The Law Society and HMLR have moved toward accepting some electronic signatures on deeds (via Mercury-compliant signing and qualified electronic signatures), but practice still varies by lender and solicitor. Clarify early with your solicitor which of your documents must be wet-ink and plan your notary visit accordingly.
Typical workflow: schedule one or two visits to a notary in your country of residence to sign all wet-ink documents simultaneously, then courier to UK. DHL, UPS and FedEx are all reliable for this purpose; allow 2-3 working days and always use tracked service.
