Tracker mortgages move up and down with the Bank of England base rate, offering transparency and the chance to benefit if rates fall. This guide explains tracker mortgages: how they work, the current example, their pros and cons, the different types, and who they tend to suit.
What a tracker is
A tracker mortgage has an interest rate that follows, or tracks, the Bank of England base rate plus a set margin. For example, a tracker at base rate plus 0.6% would be 4.35% when the base rate is 3.75%. Because it follows the base rate directly, your rate, and so your payments, rise and fall as the base rate changes, usually within a month of any change.
How it works
The margin above the base rate is fixed for the deal, but the base rate itself can change at each Bank of England meeting, as our guide to the base rate and your mortgage explains. So if the base rate rises by 0.25%, your tracker rate rises by the same, and if it falls, your rate falls too. This direct link makes trackers transparent: you can see exactly how your rate is set.
A current example
In mid-2026, with the base rate at 3.75%, a tracker priced at base plus 0.6% would charge 4.35%. If the base rate rose to 4%, the tracker would become 4.6%; if it fell to 3.5%, the tracker would become 4.1%. This shows how your payments move directly with the base rate, which is the defining feature of a tracker mortgage.
The advantages
Trackers are transparent, since your rate is simply the base rate plus a known margin, and you benefit immediately if the base rate falls. Many trackers also have low or no early repayment charges, giving flexibility to overpay or switch, as our guide to fixed versus variable explains. For those expecting rates to fall or wanting flexibility, a tracker can be attractive.
The disadvantages
The main drawback is uncertainty: if the base rate rises, your rate and payments rise too, which can strain a tight budget. Unlike a fix, a tracker offers no protection from increases. So trackers suit those who can absorb potential rises, and they carry more risk than a fixed rate for anyone whose budget could not cope with higher payments if the base rate climbs.
Lifetime and deal-period trackers
Trackers come in two main forms: those that track for a set period, such as two or five years, before reverting to the standard variable rate, and lifetime trackers that follow the base rate for the whole mortgage term. Deal-period trackers usually have a lower margin, while lifetime trackers offer long-term transparency, often with no early repayment charges, as our guide to discount mortgages notes by comparison.
Who a tracker suits
Trackers suit people who can cope with payments that may rise, want to benefit if rates fall, or value the flexibility of low early repayment charges, perhaps planning to overpay or move soon. They are less suitable for those needing the certainty of fixed payments on a tight budget. Weighing your budget, flexibility needs and view on rates helps you decide whether a tracker fits your circumstances.
Collars and floors
Some trackers have a collar or floor, a level below which the rate will not fall even if the base rate drops further. This protects the lender's margin but limits your benefit from very low rates. If you are considering a tracker, it is worth checking whether it has a collar, as it affects how much you would gain if the base rate fell significantly, which is an important detail in the deal's terms.
Fees and early repayment charges
Like other deals, trackers can have arrangement fees, and while many have low or no early repayment charges, some do, especially fixed-term trackers, as our guide to ERCs explains. Checking the fees and any early repayment charges helps you compare a tracker fairly against other deals and understand the flexibility it really offers, rather than assuming all trackers are penalty-free.
When trackers beat fixes
A tracker tends to work out cheaper than a fix when the base rate stays low or falls during your deal, since you benefit from the lower rate while a fixed borrower does not. Conversely, if the base rate rises, a fix taken beforehand can prove cheaper. Since no one can predict rates with certainty, the choice is partly about your view and partly about your tolerance for uncertainty.
Trackers and remortgaging
Because many trackers have low or no early repayment charges, they can suit people who expect to remortgage or move before long, giving flexibility to switch without penalty, as our guide to remortgaging explains. A tracker can act as a flexible holding deal while you wait for a better time to fix or sell, which is one practical reason borrowers choose them.
An example over time
Imagine a tracker at base plus 0.6%. With the base rate at 3.75%, you pay 4.35%. If the base rate were cut twice by 0.25%, your rate would fall to 3.85%, lowering your payments. If instead it rose twice, your rate would climb to 4.85%, raising them. This illustrates how a tracker hands you both the benefit of cuts and the risk of rises directly.
Trackers in a falling-rate environment
Trackers are often most attractive when rates are expected to fall, since you benefit automatically from each cut without remortgaging. In a falling environment, a tracker can outperform a fix taken at a higher rate. Of course, expectations can be wrong, and rates can rise instead, so a tracker is a calculated choice rather than a certainty, suited to those comfortable taking that view, as our guide to the base rate explains.
Combining a tracker with overpayments
Because many trackers allow penalty-free overpayments, they can suit borrowers who want to overpay and reduce their mortgage faster, as our guide to overpaying explains. The flexibility to overpay, plus benefiting from any rate falls, can make a tracker an efficient choice for disciplined borrowers with some financial headroom, who value the freedom to pay down the loan whenever they have spare funds.
Is a tracker right for you?
A tracker is right for you if you can comfortably absorb the possibility of higher payments, want transparency and the chance to benefit from rate falls, and value flexibility such as penalty-free overpayments or switching. If a rise in payments would strain your budget, the certainty of a fix is usually safer. Matching the choice honestly to your finances and temperament, rather than chasing the lowest current rate, leads to the best decision.
In short
A tracker mortgage follows the Bank of England base rate plus a fixed margin, so your rate and payments move directly with the base rate, usually within a month of a change. In mid-2026 a tracker might be base plus 0.6%, or 4.35%. Trackers are transparent and benefit you if rates fall, often with low early repayment charges, but your payments rise if the base rate does. They suit flexible budgets.
