Once you’ve found a lender willing to work with your expat situation, the next decision is usually fixed or variable. It’s a genuinely important choice, and the right answer depends more on your circumstances than on trying to predict where rates are heading.
How Fixed Rate Mortgages Work
A fixed rate stays the same for an agreed period – typically two, three, or five years – regardless of what happens to the wider market during that time. Your monthly payment is predictable for the whole term, which matters if you’re budgeting in a foreign currency and don’t want an additional layer of uncertainty on top of exchange rate movements you can’t control anyway.
How Variable Rate Mortgages Work
A variable rate moves in line with an underlying reference rate, most commonly tracking the Bank of England base rate directly, or moving at the lender’s discretion on a standard variable rate. Your payment can go up or down during the term, sometimes at short notice, which suits people comfortable with some uncertainty in exchange for potentially lower costs if rates fall.
Why This Decision Matters More for Expats
If you’re earning in a foreign currency and repaying in sterling, you’re already managing one layer of uncertainty from exchange rate movements. Stacking a variable interest rate on top adds a second, separate source of unpredictability to your monthly costs. Many expats prefer the fixed route specifically to remove one variable from an already complex financial picture, even if it means paying slightly more for that certainty.
How Long You Plan to Stay Affects the Right Choice
If you expect to sell or remortgage within a couple of years – for example, ahead of a planned move back to the UK – a shorter fixed term or a variable rate without early repayment charges might suit you better than locking into a longer fixed period you may end up paying to exit early. Our Expat Remortgages page covers the options for switching once your current deal ends.
What Happens When Your Fixed Rate Ends
Most fixed rates revert to the lender’s standard variable rate once the term ends, which is often considerably higher than either the original fixed rate or competitive rates available elsewhere. Timing a remortgage or product transfer before this happens, rather than after, is usually the better approach. Our Expat Residential Remortgage page covers what that process typically involves, and our Mortgage Porting page covers one option if you’re also moving property at the same time.
Frequently Asked Questions
Is a fixed rate always more expensive than variable?
Not necessarily at the outset, though it depends on market conditions at the time. The value of a fixed rate is the certainty it provides, not always a lower headline cost.
Can I switch from variable to fixed partway through my mortgage?
Often yes, though early repayment charges may apply depending on your specific product and how far into the term you are.
Do expat mortgages typically offer the same range of fixed terms as UK resident mortgages?
Usually a narrower range – two and five-year fixes are the most commonly available terms for expat products specifically.
What happens if I need to sell during a fixed rate period?
Early repayment charges commonly apply if you exit before the fixed term ends, so it’s worth factoring in your likely timeline before choosing a longer fixed period.
