Fixed vs Variable Mortgage 2026: Which Should You Pick?
Pick a mortgage rate and you are really making a bet about the future — and choosing how much certainty you are willing to pay for. A fixed rate locks your monthly payment for 2, 5 or 10 years, shielding you from rate rises but charging you to leave early. A variable or tracker rate moves with the Bank of England base rate: usually cheaper to start and easier to exit, but your payments can climb without warning. This 2026 comparison weighs certainty against flexibility, explains early repayment charges, sets out the Bank of England rate outlook, and works a real example on a £250,000 mortgage.
TL;DR — 30-Second Summary
- • Want a stable budget: fix — your payment is locked regardless of base-rate moves
- • Want flexibility: a tracker is easier to leave and benefits if rates fall
- • Early exit: fixed deals carry early repayment charges; trackers often little or none
- • The honest truth: nobody can reliably forecast rates — decide on your need for certainty, not predictions
How Each Type Works
- • Payment locked for 2, 5 or 10 years
- • Protected if base rate rises
- • You miss out if base rate falls
- • Early repayment charges to leave early
- • Certainty for budgeting
- • Moves with the Bank of England base rate
- • Usually cheaper at the start
- • Benefits if base rate falls
- • Payments rise if base rate rises
- • Often low or no ERCs — easy to exit
Fixed, Tracker and SVR Explained
“Variable” covers several products. A tracker follows the base rate plus a set margin (e.g. base + 0.75%), moving transparently with it. A standard variable rate (SVR)is the lender's own rate, changed at their discretion and usually the most expensive — it is what you fall onto when a deal ends, and is normally to be avoided. A discount rate sits a set amount below the SVR for a period.
When people choose “variable”, they usually mean a tracker; the SVR is a place to move off, not to settle on. A fixed rate, by contrast, ignores all base-rate movements for the agreed term.
Early Repayment Charges
An early repayment charge (ERC) penalises leaving a deal early — repaying, remortgaging away, or overpaying beyond the allowed limit during the deal period. It is typically a percentage of the balance that steps down over the term, such as 5% in year one falling to 1% in the last year, and can run to thousands of pounds.
ERCs are heaviest on fixed deals, where they enforce the lock-in, and lightest (often nil) on trackers — a big part of the tracker's flexibility appeal. Most deals allow penalty-free overpayments up to about 10% a year. Always check the ERC schedule before committing.
The Bank of England Outlook
Mortgage pricing tracks the Bank of England base rate and the markets' expectations of where it is heading. No one can predict the path with certainty, and the picture shifts with inflation and the wider economy.
The practical takeaway is to not bet the house on a forecast. If markets expect cuts, fixed deals may already price some in, and a tracker lets you benefit from cuts as they land. If rates may rise or stay high, fixing buys protection. Most borrowers should decide on their need for certainty and their capacity to absorb payment rises, not on a guess about the base rate.
Worked Example: £250,000 Mortgage
A £250,000 repayment mortgage over 25 years. The tracker starts cheaper; the fixed rate is slightly higher but immovable. The figures are illustrative to show the mechanics, not a quote:
| Scenario | Fixed at 4.5% | Tracker starting at 4.0% |
|---|---|---|
| Monthly payment at outset | ~£1,390 | ~£1,320 |
| If base rate rises 1% | ~£1,390 (unchanged) | ~£1,460 |
| If base rate falls 1% | ~£1,390 (still fixed) | ~£1,190 |
| Leaving early | ERC of thousands | Often little or none |
The tracker is £70 a month cheaper to start and could fall further if rates drop — but a 1% rise turns that saving into a £70 monthly premium over the fix. The fixed rate buys certainty: the same payment whatever happens, at the cost of a slightly higher start and a penalty to leave. Model your own numbers with the mortgage calculator.
Which Should You Choose?
Fix if a stable, predictable payment matters more to you than chasing the lowest possible rate — it protects your budget against rises and removes the worry, which for most homeowners is worth the small premium. Choose a tracker if you value flexibility, expect to overpay or move, can comfortably absorb a payment rise, and want to benefit from any rate cuts. Either way, decide on your circumstances and risk tolerance, not on a forecast of the base rate that no one can make reliably.
