Fixed vs Tracker Mortgage 2026: Which Rate Type Wins?
A fixed-rate mortgage locks your payment for a set period, giving certainty whatever happens to interest rates. A tracker moves with the Bank of England base rate, so your payment falls when rates fall and rises when they rise. For 2026/27 the choice turns on how much you value predictable payments, your view on where rates are heading, and how much flexibility you want. This comparison sets out the cost, the risk and the flexibility of each, with a worked example on illustrative rates.
TL;DR - 30-Second Summary
- - Fixed: the same payment for the deal period, protected from rate rises
- - Tracker: rate follows the base rate, falling and rising with it
- - Cheaper option depends on rate moves nobody can predict
- - Trackers can be more flexible, sometimes with no early repayment charge
Side by Side
| Feature | Fixed Rate | Tracker |
|---|---|---|
| Monthly payment | Stays the same | Moves with base rate |
| If rates rise | Protected | Payment rises |
| If rates fall | No benefit until you remortgage | Payment falls automatically |
| Certainty | High | Low |
| Early repayment charge | Usually yes | Often none on flexible trackers |
| Best for | Budget certainty | Flexibility and falling rates |
Worked Example: £200,000 over 25 Years
Take a £200,000 repayment mortgage over 25 years. Suppose a fixed deal is offered at an illustrative 5% and a tracker starts at 4.75%. The tracker is cheaper to begin with, but its payment changes if the base rate moves.
| Scenario | Approx monthly payment |
|---|---|
| Fixed at 5% | ~£1,169, unchanged |
| Tracker starting at 4.75% | ~£1,141 to start |
| Tracker if rate rises to 5.75% | ~£1,259 |
| Tracker if rate falls to 3.75% | ~£1,028 |
The tracker starts about £28 a month cheaper than the fix, but a one point rise pushes it nearly £90 above the fixed payment, while a one point fall saves over £140 a month. Fixed buys certainty; tracker hands you the upside and downside of rate moves. Rates are illustrative only; model your own with the mortgage calculator.
The Risk Angle
A fixed rate removes interest rate risk for the deal period, so you can budget with confidence, which matters most if a higher payment would stretch your finances. The trade-off is that you do not benefit if rates fall, and you usually face an early repayment charge if you want to leave early.
A tracker passes rate risk straight to you. You gain instantly when the base rate is cut, but you must be able to absorb increases. Many flexible trackers have no early repayment charge, so you can switch to a fix if rates start climbing, which softens the risk for borrowers who watch the market.
Who Should Choose What
- - You want predictable monthly payments
- - A rate rise would strain your budget
- - You value certainty over chasing a lower rate
- - You plan to stay put for the deal period
- - You can absorb rises in your payment
- - You think rates may fall
- - You want flexibility, ideally with no ERC
- - You want to benefit quickly from base rate cuts
Verdict
There is no single winner, because the cheaper option depends on rate moves no one can predict. A fixed rate is the right choice for borrowers who prize certainty and protection against rises, especially when budgets are tight. A tracker suits those who can ride out increases, expect rates to fall, or value the flexibility of a deal with no early repayment charge. Many people sensibly default to the security of a fix, while confident, financially resilient borrowers lean toward a tracker. Compare the actual deals on offer and consider speaking to a mortgage adviser.
