Tracker Mortgages
A tracker mortgage moves with the Bank of England base rate rather than staying fixed – meaning your monthly payment can genuinely rise or fall throughout your deal. Understanding exactly how this works helps you decide whether that trade-off suits your circumstances.
What a Tracker Mortgage Actually Is
A tracker mortgage is a type of variable rate mortgage where your interest rate directly follows an external benchmark, almost always the Bank of England base rate, plus a fixed margin agreed with your lender. If your tracker is priced at “base rate plus 0.75%” and the base rate is currently 3.75%, you’d be paying 4.5% – and if the base rate moves, your rate moves with it, typically within about a month.
The Current Base Rate
As of the most recent Bank of England Monetary Policy Committee decision, the base rate stands at 3.75%, held at the July 2026 meeting, with the next review scheduled for September 2026. The MPC meets eight times a year to set this rate, and it’s worth understanding that it can move at any of these meetings, in either direction, depending on inflation and wider economic conditions.
How Rate Changes Actually Affect Your Payments
Because your tracker rate is calculated as base rate plus a fixed margin, any change to the base rate flows through directly to what you pay each month.
Worked Example: A Rate Cut
On a £200,000 repayment mortgage over 25 years at 5%, your monthly payment would be around £1,169. If the base rate fell by 0.25%, taking your tracker rate to 4.75%, your payment would drop to roughly £1,140 – a saving of around £29 a month.
Worked Example: A Rate Rise
Using the same mortgage, if the base rate instead rose by 0.25% to take your rate to 5.25%, your payment would increase to around £1,198 – roughly £29 a month more. A larger 0.5% rise on the same mortgage would add closer to £60 a month, or around £720 over a year.
Term Trackers vs Lifetime Trackers
Most tracker mortgages are what’s called a term tracker, following the base rate for a set period – commonly two or five years – after which the mortgage reverts to the lender’s Standard Variable Rate unless you arrange a new deal. A smaller number of lenders offer a lifetime tracker, which follows the base rate for the entire mortgage term and never automatically reverts to a Standard Variable Rate. It’s worth understanding which type you’re being offered, since the long-term cost implications genuinely differ.
Collars and Caps
Some tracker deals include a collar, a floor below which your rate won’t fall even if the base rate drops further, limiting how much benefit you’d see from a significant rate cut. Others include a cap, a ceiling above which your rate can’t rise regardless of base rate increases, offering a degree of protection against runaway rate rises. Not every tracker includes either feature, so it’s worth checking the specific terms of any deal you’re considering rather than assuming protection exists by default.
Tracker vs Standard Variable Rate: A Genuine Distinction
It’s worth being clear that a tracker mortgage and a Standard Variable Rate mortgage are different products, even though both are variable. A tracker’s rate is contractually tied to an external benchmark and must move when that benchmark does; a lender’s SVR is set entirely at their own discretion, only loosely influenced by the base rate, and can change independently of it. This is exactly why most trackers and fixed-rate deals eventually revert to the lender’s SVR once their initial period ends – it’s the lender’s own default rate, not another tracker or fixed product.
Tracker vs Fixed-Rate: The Genuine Trade-Off
A tracker can offer lower payments if the base rate falls, but genuinely exposes you to higher payments if it rises. Our Fixed-Rate Mortgages page covers the alternative in full detail – the dominant choice for UK homeowners, offering complete payment certainty in exchange for not benefiting if rates fall, worth comparing properly against a tracker based on your own risk tolerance.
Tracker vs Discount Mortgages
A discount mortgage is a different structure again – it tracks a fixed amount below the lender’s own SVR, rather than following an external base rate directly. Because the lender controls their SVR and can adjust it somewhat independently, a discount mortgage’s movements can be less predictable than a tracker’s, which follows a transparent, publicly available benchmark.
Flexibility and Early Repayment
Many, though not all, tracker mortgages allow unlimited overpayments and switching to another deal without an Early Repayment Charge, since there’s no fixed-term rate commitment being broken in the way there would be with a fixed-rate product. It’s worth checking your specific deal’s terms rather than assuming this flexibility applies universally, since some trackers do still carry an ERC during an initial period.
How Lenders Stress-Test Tracker Affordability
Given a tracker rate can genuinely rise, lenders typically stress-test your affordability at a meaningfully higher rate than your actual starting rate – commonly around 3% above your initial tracker rate – to confirm you could still afford your payments if rates rose significantly during your deal. It’s worth running this same calculation yourself honestly before committing, to make sure a genuine rate rise wouldn’t cause real financial strain.
Why Some Borrowers Choose a Tracker Over a Fixed Rate
A tracker can make sense if you believe the base rate is more likely to fall than rise over your deal period, or if the tracker rate on offer is already more competitive than comparable fixed-rate deals at the time you’re applying. Given roughly 591,000 UK mortgage holders are currently on tracker deals, it’s a genuinely mainstream choice, not a niche one, though it does require being comfortable with payment amounts that can change.
Why a Fixed Rate Might Suit You Better
If budgeting certainty matters more to you than the possibility of a lower rate, or if your finances genuinely couldn’t absorb a meaningful payment increase, a fixed-rate mortgage removes this uncertainty entirely for your fixed period, at the cost of not benefiting if rates fall. It’s worth discussing your own risk tolerance and financial buffer honestly with your broker before choosing between the two.
Frequently Asked Questions
What’s the current Bank of England base rate?
As of the most recent Monetary Policy Committee decision, the base rate stands at 3.75%, though this is reviewed eight times a year and can change at any meeting.
How quickly does my tracker rate change after a base rate move?
Typically within about a month of a Bank of England base rate change, since lenders adjust tracker rates automatically to reflect it.
What’s the difference between a term tracker and a lifetime tracker?
A term tracker follows the base rate for a set period before reverting to the lender’s Standard Variable Rate; a lifetime tracker follows the base rate for the entire mortgage term.
Is a tracker mortgage the same as my lender’s Standard Variable Rate?
No – a tracker is contractually tied to an external benchmark and must move with it; an SVR is set at the lender’s own discretion and only loosely influenced by the base rate.
Can I overpay or switch away from a tracker without a penalty?
Often yes, though not universally – it’s worth checking your specific deal’s terms, since some trackers do carry an Early Repayment Charge.
