Tracker Mortgage vs Fixed-Rate Mortgage 2026: Which Is Right for You?
A tracker mortgage moves in lockstep with the Bank of England base rate, so your payment can rise or fall during the deal. A fixed-rate mortgage locks your payment for a set period — typically 2 or 5 years — regardless of what happens to interest rates. Neither is objectively "better"; the right choice depends on your appetite for payment-amount risk and your view on where rates are heading in 2026.
TL;DR
- Tracker mortgage: Rate = base rate + fixed margin; payment moves with base rate changes; some carry no ERC
- Fixed-rate mortgage: Payment locked for the deal period (usually 2–5 years); budgeting certainty; ERC if you exit early
Side-by-Side Comparison
| Feature | Tracker Mortgage | Fixed-Rate Mortgage |
|---|---|---|
| Rate mechanism | Base rate + fixed margin | Fixed for the deal period |
| Payment certainty | None — moves with base rate | Full — same payment every month |
| If rates fall | Payment falls automatically | No benefit until deal ends |
| If rates rise | Payment rises automatically | No impact until deal ends |
| Typical deal length | 2 years common (some longer) | 2 or 5 years most common |
| Early Repayment Charge | Varies — some have none | Usually applies throughout the fixed period |
| Best for | Borrowers comfortable with payment variability | Borrowers who want budgeting certainty |
How Tracker Mortgages Work
A tracker mortgage sets your interest rate at a defined margin above the Bank of England base rate — for example, "base rate + 0.75%". Whenever the Monetary Policy Committee changes the base rate, your mortgage rate changes by the same amount, and your payment is recalculated, typically taking effect within one to two payment cycles. Some trackers include a "collar" (a floor below which the rate cannot fall even if the base rate keeps dropping) — check the offer document for any such feature.
How Fixed-Rate Mortgages Work
A fixed-rate mortgage locks your interest rate — and therefore your monthly payment — for an agreed period, most commonly 2 or 5 years, though 3, 7 and 10-year fixes are also available. Whatever happens to the base rate or swap rates during that period, your payment stays the same. At the end of the fixed term, the mortgage usually reverts to the lender's Standard Variable Rate (SVR) unless you remortgage or take a new product with the same lender.
How to Decide
The decision comes down to your tolerance for payment variability and your view on rate direction. Borrowers with tight monthly budgets, or those who simply prefer certainty for planning purposes, tend to favour fixed-rate deals even if the tracker's initial rate looks marginally cheaper. Borrowers with more financial headroom, who are comfortable absorbing a payment increase if rates rise, and who want to benefit automatically if rates fall, may prefer a tracker — particularly a no-ERC tracker that also gives flexibility to switch or overpay freely.
