Fixed vs tracker mortgage: key differences explained
The simplest way to compare a fixed vs tracker mortgage is to look at how the interest rate is set: fixed-rate deals stay the same for a set period, while tracker deals move with the base rate. Understanding this fixed vs tracker mortgage structure helps you choose based on budget certainty and risk tolerance.
What is a fixed-rate mortgage?
A fixed-rate mortgage means your interest rate is locked for a defined period — typically 2, 3, 5, or sometimes 10 years. Your monthly payments are predictable during this period, even if market rates rise.
Fixed-rate example
Mortgage: £250,000
Deal: 4.5% fixed for 5 years
Outcome: payments stay broadly stable until the fixed period ends (assuming you don’t change the mortgage).
What is a tracker mortgage?
A tracker mortgage follows the Bank of England base rate. Your rate is usually: Base rate + a fixed margin set by the lender. That means your payments can rise or fall when the base rate changes.
Tracker mortgage example
Base rate: 5.25%
Tracker deal: base rate + 1.00%
Your rate: 6.25%
If the base rate drops to 4.50%, your rate becomes 5.50% automatically.

Tracker mortgage — pros

Fixed vs tracker mortgage: which is better in 2026?
There isn’t one “best” answer — the best fixed vs tracker mortgage choice depends on your priorities and your view on interest-rate direction.
When a fixed-rate mortgage often makes sense
- You want predictable monthly payments.
- You’d struggle if payments rose unexpectedly.
- You plan to stay in the property for at least the fixed term.
When a tracker mortgage often makes sense
- You expect rates to fall and can handle volatility.
- You value flexibility (check ERCs carefully).
- You have a buffer in your monthly budget.
How to choose: fixed vs tracker mortgage checklist
- Compare total cost (rate + fees) — not just the headline rate.
- Check ERCs and the ability to overpay.
- Think about time horizon: 2-year vs 5-year fix, or tracker flexibility.
- Stress test payments: could you cope if your rate rose by 1–2%?
- Consider your plans: moving home soon may make long fixes less suitable.
Key takeaway
For most households, a fixed vs tracker mortgage decision comes down to stability vs flexibility. Fixed deals protect your budget; tracker deals can reward you if rates fall — but you must be comfortable with changes.
