If you're a UK expat with a mortgage on a UK property, chances are your lender deal is due for review. But in 2025, remortgaging from abroad isn't as straightforward as it once was. From lender appetite to regulatory shifts, foreign currency income to UK credit gaps — expats must now navigate a tighter, more technical market.

In this blog, we’ll explore what’s changed, what to watch out for, and how Willow Private Finance helps UK expats structure smarter remortgage solutions across residential, buy-to-let, and investment portfolios.

Why Remortgaging as an Expat Requires More Care in 2025

Many UK expats remortgage every few years to release equity, switch rates, or restructure ownership. But lenders have become more selective.

Increased scrutiny around:

• Foreign currency income (especially non-GBP salaries)
• Overseas residency and tax status
• UK credit activity or lack thereof
• Use of property — residential vs. let
• Income documentation and affordability stress testing

…has resulted in fewer mainstream options. That’s led more borrowers to seek advice from brokers experienced in both expat lending and complex income cases.

Key 2025 Changes Impacting Expat Remortgages

1. More Cautious Lender Criteria

While specialist lenders remain open to expat remortgages, they're applying stricter affordability tests — especially when borrowers are paid in USD, EUR, AED, or other foreign currencies. Some lenders now apply a 10–20% haircut to foreign income before affordability is assessed.

Willow’s expat clients often encounter complex income structures — including bonuses, commission, or income from multiple jurisdictions. See our post on Mortgages for Lawyers with Complex Income for real-world challenges and structuring solutions.

2. Loan Purpose Scrutiny: Equity Release vs. Rate Switch

Lenders now differentiate more clearly between:

• Rate switch with no new borrowing (lower bar)
• Equity release, especially when the funds are used for property investment abroad or non-UK ventures (higher bar)
•

3. Limited Access to High-Street Lenders

Even with strong finances, many expats find that mainstream banks won’t support them due to:

• Lack of UK credit activity
• Foreign tax residency
• Unfamiliarity with international payslips or banking

Instead, private banks and specialist lenders dominate the space — often offering bespoke solutions tailored to high net worth and international borrowers. Learn more in Private Bank Mortgages Explained.

4. Expat BTL Remortgaging Trends

For expats with buy-to-let portfolios, remortgaging often coincides with refinancing for:

• Portfolio restructuring
• Tax planning (via SPVs or trusts)
• Interest-only extensions or offset product switches

Case Study: Dubai-Based Client Refixes £1.2M UK Mortgage

One of our recent clients, a UK national living in Dubai, came to us when his five-year fixed rate was expiring. His salary was in AED, he had no UK credit activity for over six years, and his lender would not offer a new rate.

We secured a remortgage with a specialist lender at 70% LTV, with no UK address requirement, and structured the mortgage on an interest-only basis — using rental income to meet affordability.
