Continuing our series of posts on mortgages, today we’ll be discussing tracker mortgages.
I covered fixed rate mortgages already, now it’s time to track.
Tracker mortgages are a popular product and has benefits over other types of borrowing. But is it right for you?
Let’s find out!
What is a tracker mortgage?
A tracker mortgage is a type of variable mortgage that directly follows the Bank of England (BoE) base rate, plus a set margin.
For example:
- If the BoE base rate is 4.0% and your tracker is +1%, you’ll pay 5.0%.
- If the base rate falls to 3.5%, your payment will fall to 4.5%.
The key difference between a tracker and a standard variable rate (SVR) is that with a tracker, your lender is obliged to adjust your rate in line with base rate changes.
With an SVR, lenders can move rates up or down at their discretion.
How does a tracker mortgage work?
When you buy a tracker mortgage, you’ll usually commit to a specific percentage. It can be anything from .25% up to 2% or more.
- Margin above base rate: The margin can range from +0.25% to +2% or more, depending on the deal.
- Length of deal: Trackers can be permanent (for the life of the mortgage) or temporary (e.g. a 2- or 5-year tracker, after which you move to SVR).
- Early repayment charges (ERCs): Many tracker products have ERCs if you switch before the deal ends, but some have minimal penalties compared to fixed rates.
- Monthly payments: These rise or fall automatically with the BoE base rate.
Collars and caps: what you need to know
When shopping for trackers, you’ll often see the terms collar and cap.
- Collar: The minimum rate you’ll pay, even if the base rate falls below that level. For example, with a collar of 1%, your rate won’t drop below 1% + margin.
- Cap: The maximum rate you’ll pay, no matter how high the base rate climbs.
Caps provide reassurance against runaway increases but usually come at a higher initial cost. Collars limit how much you can benefit from falling rates.
Tracker mortgages: The current picture
- The Bank of England base rate is 4.0% (September 2025), following cuts earlier this year.
- Many lenders have reduced tracker rates in line with the cuts, unlike fixed or SVR mortgages, which often lag.
- Average tracker margins in 2025 range between +0.5% and +1.25% depending on deposit size (LTV).
- Borrowers with higher deposits often get the best tracker rates.
Pros of tracker mortgages
- Optional caps: Some products let you limit the maximum rate you’ll ever pay.
- Lower starting rates: Often cheaper than equivalent fixed deals, especially when base rates are falling.
- Transparency: Your rate is tied directly to the BoE base rate, so changes are predictable.
- Potential to save if rates fall: You benefit immediately when the base rate drops.
- Flexibility: Some trackers have lower ERCs than fixed mortgages, making it easier to switch.
Cons of tracker mortgages
- Uncertainty: Payments rise if the base rate increases, making budgeting harder.
- Caps and collars cost extra: Adding a cap increases the deal’s cost, while collars limit your benefit when rates fall.
- Stress on household budgets: You need financial flexibility to cope with unexpected rises.
- Fewer product choices: Trackers are less common than fixed deals in the UK market.
Tracker vs fixed rate mortgages
| Feature | Tracker | Fixed |
|---|---|---|
| Link to base rate | Always moves with base rate | Unaffected during fixed period |
| Starting rates | Often cheaper | Usually more expensive |
| Budgeting | Payments can rise or fall | Payments remain predictable |
| Flexibility | Some allow easy switching | Hefty early repayment charges |
| Best for | Those expecting stable or falling rates | Those wanting certainty |
When is a tracker mortgage a good idea?
A tracker may suit you if:
- You believe the base rate will stay stable or fall.
- You have a financial buffer to handle possible rises.
- You want flexibility and don’t want to be tied into a fixed rate with large ERCs.
- You’re planning to remortgage soon and want a short-term option.
It may not be right for you if:
- You need certainty in monthly payments.
- Your budget is already stretched and can’t handle surprises.
- You’re risk-averse and prefer stability.
Tracker mortgages – Yes, or no?
With the BoE base rate falling in 2025, tracker mortgages look more attractive than they did in 2023–24. They allow you to benefit immediately from rate cuts, unlike fixed or SVR mortgages.
However, trackers come with risk: if inflation rises again and the BoE hikes rates, your repayments could increase quickly.
The decision comes down to your risk tolerance, budget flexibility, and financial goals.
Tracker mortgage FAQs
How quickly does my tracker mortgage change when the base rate changes?
Most lenders adjust your tracker rate within 30 days of the BoE announcing a change. Your monthly payment will then rise or fall accordingly.
Are tracker mortgages cheaper than fixed deals right now?
In many cases, yes. As of September 2025, some tracker products have lower rates than equivalent fixed deals. But trackers carry more risk if rates rise again.
What’s the difference between a tracker mortgage and a variable mortgage?
A tracker is contractually tied to the BoE base rate plus a margin. A variable mortgage (like SVR) changes at the lender’s discretion and doesn’t necessarily follow the base rate.
Can I switch from a tracker to a fixed mortgage later?
Yes, though some trackers have early repayment charges. Many are more flexible than fixed deals, so switching can be easier.
Do all trackers have collars or caps?
No. Some trackers have neither, meaning your payments can fall as low as the base rate allows, but also rise without limit. Others include collars and caps, usually at extra cost. Always check the small print.
