When you’re choosing a new mortgage deal, one of the first decisions is whether to go fixed or tracker. Both have genuine advantages, and the right choice depends on your circumstances, your appetite for risk, and how the wider interest rate environment looks in 2026.
How fixed-rate mortgages work
A fixed-rate mortgage locks your interest rate for an agreed period — commonly two, three or five years. Whatever happens to the Bank of England base rate or the wider market during that time, your monthly payment stays the same.
The appeal: certainty. You know exactly what you’ll pay each month, which makes budgeting easier and protects you if rates rise during your fixed term.
The trade-off: if rates fall after you’ve fixed, you won’t benefit until your deal ends. Most fixed deals also carry an Early Repayment Charge if you want to leave before the term is up.
How tracker mortgages work
A tracker mortgage moves directly in line with the Bank of England base rate, usually at a set margin above it. If the base rate falls, your payments fall too — and if it rises, so do your payments.
The appeal: you benefit immediately if rates fall, and tracker deals sometimes start with a lower rate than comparable fixes.
The trade-off: your monthly payment isn’t guaranteed to stay the same, which makes budgeting harder and means you’re exposed if rates rise.
Questions worth asking yourself
- How would a rise of 1–2 percentage points affect my monthly budget? If that would cause real strain, a fix may suit you better.
- Do I expect my circumstances to change soon — moving, changing jobs, starting a family — where payment certainty would help?
- Am I comfortable with some month-to-month variation in exchange for potential savings if rates fall?
- How long do I realistically plan to stay in this property or with this lender?
There isn’t a universally “right” answer
Fixed and tracker mortgages both have a place, and what suits a first-time buyer with a tight monthly budget is often different from what suits someone with more financial headroom or a shorter time horizon. Some lenders also offer trackers with no Early Repayment Charge, giving more flexibility to switch later if a good fixed deal appears.
A note on timing
Rate expectations shift as economic data comes in, so what looks like the better option can change over the weeks it takes to complete a mortgage application. This is exactly the kind of decision where comparing the whole market at the point you actually apply — rather than relying on general commentary — makes a real difference.
Interest rates and product availability change regularly; the general points above should not be taken as a recommendation for your specific circumstances.
