- A tracker mortgage follows the Bank of England base rate automatically
- When rates fall, your payment drops — no remortgage needed
- Many trackers have no early repayment charges, giving full flexibility
- Right for borrowers with financial headroom who expect rates to keep falling
When choosing a mortgage, one of the first decisions is whether to fix your rate or go variable. Tracker mortgages are the most transparent variable option — and with the Bank of England base rate expected to fall further, they are attracting more attention than at any point in the last decade.
How does a tracker mortgage work?
A tracker mortgage is set at a fixed margin above the Bank of England base rate. If the base rate is 4.25% and your tracker is “base rate + 0.75%”, your mortgage rate is 5.00%.
When the base rate moves — which the Bank of England’s Monetary Policy Committee decides roughly every six weeks — your mortgage rate moves immediately and automatically. You do not need to take any action.
Example
You have a £300,000 tracker mortgage at base rate + 0.75%. The base rate is 4.25%, so your rate is 5.00% and monthly payment is roughly £1,754. The Bank of England cuts the base rate by 0.25% to 4.00%. Your rate automatically drops to 4.75% and your monthly payment falls to around £1,711 — saving £43/month with no action from you.
Types of tracker mortgage
| Type | How it works | Best for |
|---|---|---|
| Term tracker | Follows the base rate for the full mortgage term (e.g. 25 years) | Borrowers wanting long-term flexibility, usually no ERCs |
| Short-term tracker | Tracks for 2 or 5 years, then reverts to lender SVR | Those expecting rate falls in the short term |
| Offset tracker | Tracker rate + savings offset against balance | Higher earners with significant savings to offset |
Tracker vs fixed: what is the real difference?
| Fixed rate | Tracker | |
|---|---|---|
| Payment certainty | 100% certain for fixed period | Moves with base rate |
| If rates fall | You miss out | You benefit automatically |
| If rates rise | Fully protected | Payment increases |
| Early repayment charges | Almost always (1%–5%) | Often none (especially term trackers) |
| Overpayments | Usually 10%/year limit | Often unlimited |
| Initial rate | Typically slightly higher | Often slightly lower |
The Bank of England base rate: recent context
The base rate peaked at 5.25% in August 2023 — a 15-year high — following rapid rises from 0.1% in late 2021 to tackle inflation. It has since fallen to 4.25% as inflation has come under control. Most market forecasters expect further gradual cuts through 2026.
Current context
Tracker mortgage holders who took products in 2023 at the rate peak have seen automatic payment reductions as the base rate has fallen. This is exactly the environment where trackers outperform fixed rates — and why they are worth serious consideration right now.
Who is a tracker mortgage right for?
- You expect rates to keep falling and want to benefit without remortgaging
- Your budget has headroom — you can absorb a £100–£200/month increase if rates rise
- You may sell or move in 2–3 years and want no early repayment penalties
- You want to overpay freely — many trackers allow unlimited overpayments
Not right for everyone
If you are on a tight budget where a £150/month increase would cause real difficulty, a fixed rate gives you the certainty you need. A broker can model both scenarios in concrete monthly payment terms for your loan size.
Frequently asked questions
Can I switch from a tracker to a fixed rate?
Yes — if your tracker has no early repayment charges (most term trackers do not), you can switch to a fixed rate at any time. This gives you the best of both worlds: benefit from rate falls now, with the option to lock in if rates start rising sharply.
What happens when my tracker deal ends?
A short-term tracker reverts to the lender’s standard variable rate (SVR) — typically 2–4% above current deal rates. Remortgage before this happens; your broker can start the process 3–4 months before the deal ends.
What is the difference between a tracker and a discount mortgage?
A discount mortgage is set below the lender’s SVR — but the lender can change the SVR at any time. A tracker is linked to the Bank of England base rate, an independent public benchmark. Trackers are more transparent and predictable.
