Fixed vs Tracker Mortgage: Which Is Right for You in 2026?

Choosing a mortgage type is a trade-off between certainty and flexibility. With Bank Rate at 3.75% and average fixed rates around 5.13% (2-year) and 4.98% (5-year) as of Sept 2026, here’s how the main options compare.

Fixed-rate mortgages

Your interest rate, and therefore your payment, is locked for a set period: usually 2, 3, 5 or 10 years. After that you move to the lender’s standard variable rate unless you switch.

Pros

• Certainty: your payment won’t change if rates rise
• Easier budgeting, especially on a tight budget
• Longer fixes can have a lighter affordability stress test

Cons

• No benefit if rates fall
• Early repayment charges (often 1–5%) if you leave early or overpay above the allowance
• Product fees can be high on the lowest rates

Tracker mortgages

The rate tracks Bank Rate plus a fixed margin, for example Bank Rate + 0.75%. When the Bank of England changes rates, your payment changes, usually from the next month.

Pros

• Payments fall straight away if Bank Rate is cut
• Many trackers have no early repayment charges, so you can switch to a fix later
• Transparent: you know exactly what drives your rate

Cons

• Payments rise if Bank Rate rises
• Harder to budget
• Some have a “collar”: a minimum rate even if Bank Rate falls further

Standard variable rate (SVR) and discount mortgages

The SVR is the rate the lender sets for borrowers whose deal has ended. It’s usually much higher than new deals, and the lender can change it at any time. Discount mortgages offer a set discount off the SVR for a period. They’re rarer now and less transparent than trackers.

2-year, 5-year or 10-year fix?

Feature	2-year	5-year	10-year
Rate certainty	Short	Medium	Long
Flexibility to switch	High	Medium	Low (big ERCs)
Fees	Paid more often	Less often	Least often
Good if…	You expect rates to fall or plan to move	You want stability through a period of change	You value certainty above all

When 5-year rates are close to or below 2-year rates, as they have been through much of 2026, longer fixes become more attractive, because you get extra certainty for little or no extra cost.

How to decide

1. How tight is your budget? If a 2-point rise would cause real hardship, certainty matters most.
2. Are you likely to move or overpay a lot? Prioritise flexibility: a shorter fix or a tracker without ERCs.
3. What do the numbers say? Compare deals by true cost over the period, including fees, with the remortgage calculator.
4. What happens at the end? Model the reversion in the mortgage calculator.

Nobody can reliably predict interest rates. Choose a deal that keeps you comfortable if your expectations turn out wrong.
