Quick Answer
A fixed-rate mortgage keeps your interest rate the same for a set period (e.g. 2, 3 or 5 years), while a tracker mortgage follows the Bank of England base rate, meaning your payments can go up or down.
What Is a Fixed-Rate Mortgage?
A fixed-rate mortgage locks your interest rate for a set period.
Key Features:
- Monthly payments stay the same
- Protection from rising interest rates
- Typically fixed for 2, 3, 5 or 10 years
Example:
If your rate is 5%, it stays at 5% for the entire fixed term — even if rates rise.
What Is a Tracker Mortgage?
A tracker mortgage follows the Bank of England base rate plus a set percentage.
Example:
- Base rate = 4%
- Your deal = Base rate + 1%
👉 You pay 5%
If the base rate changes, your payments change too.

| Feature | Fixed Mortgage | Tracker Mortgage |
|---|---|---|
| Monthly payments | Stable | Can change |

Example Comparison
Let’s say you borrow £250,000 over 25 years:
- Fixed at 5% → stable payments
- Tracker starting at 4.5% → lower initially, but could rise
If rates increase to 6%:
👉 Tracker payments increase significantly
👉 Fixed remains unchanged
