Should I Fix My Mortgage? UK Guide 2026

Should I fix my mortgage?

Deciding whether to fix your mortgage rate depends on your current deal, how long you plan to stay in the property, your appetite for payment certainty, and where interest rates are heading. There is no universally right answer — it comes down to your personal circumstances.

April 2026 snapshot: Average 2-year fixed rates sit around 4.2–4.5%; 5-year fixes around 4.0–4.3%. Tracker rates track the Bank of England base rate (4.25% as of April 2026).

Fixed vs variable: the core difference

Mortgage typeRate changes?Payment certaintyEarly repayment charge?
Fixed rateNo — locked for termHigh — payments don't changeYes
TrackerYes — moves with BoE base rateLow — payments rise/fallUsually no
Standard variable rate (SVR)Yes — lender decidesLowUsually no
Discounted variableYes — discount off SVRLowSometimes

Arguments for fixing your mortgage

  • Budgeting certainty — you know exactly what you'll pay each month
  • Protection if rates rise — you won't be affected by base rate increases
  • Peace of mind — no anxiety about rate movements for the fixed term
  • Rates are historically still relatively high — locking in now could look good if rates fall slowly

Arguments against fixing your mortgage

  • Rates may fall — if the Bank of England cuts rates, a tracker would follow, but a fixed rate wouldn't
  • Early repayment charges — breaking a fixed deal early (e.g. to move or remortgage) usually incurs a fee of 1–5% of the outstanding balance
  • You could overpay vs trackers — if variable rates drop significantly, a fixed rate costs more over the same period

2-year vs 5-year fixed: which is better?

A 2-year fix gives more flexibility and the chance to remortgage sooner if rates fall. A 5-year fix offers longer payment certainty and potentially a lower rate today, but locks you in for longer. If you're planning to move in the next 2–3 years, a 2-year fix (or a portable mortgage) is usually the better choice.

TermAverage rate (April 2026)Best for
2-year fix~4.2–4.5%Those expecting rates to fall; planning to move
5-year fix~4.0–4.3%Certainty seekers; staying put for 5+ years
10-year fix~4.3–4.6%Very long-term planners; rate-rise fearful
TrackerBoE base + margin (~4.5–5.0%)Those expecting rate cuts soon

What does Martin Lewis say about fixing?

Martin Lewis at MoneySavingExpert has consistently advised checking whether your current deal is a fixed rate about to expire — if you're rolling onto an SVR, remortgaging is almost always worthwhile. His general position is that in a high-uncertainty environment, fixing provides valuable peace of mind even if it's not always the cheapest option over time.

Should you fix in 2026?

Economists and forecasters broadly expect the Bank of England to continue cutting rates through 2026, though the pace of cuts is uncertain. This means tracker rates could become more attractive later in the year. However, fixed rates have already priced in expected cuts to some extent. If certainty is important to you, fixing still makes sense. If you believe rates will fall faster than the market expects, a short tracker could save money.

Verdict
Depends on your priorities
Fix if certainty matters more than cost. Consider a tracker if you believe rates will fall faster than the market expects and you can absorb payment variability. Always compare the best available rates through a whole-of-market broker.

Frequently asked questions

What happens when my fixed mortgage ends?
You roll onto your lender's standard variable rate (SVR), which is typically much higher — often 7–8% or more. Start shopping for a new deal 3–6 months before your fix ends to avoid this.
Can I overpay on a fixed mortgage?
Most fixed-rate mortgages allow overpayments of up to 10% of the outstanding balance per year without penalty. Exceeding this triggers an early repayment charge. Check your mortgage terms.
Is now a good time to remortgage?
If you're on your lender's SVR or approaching the end of a deal, remortgaging now is likely worthwhile even if rates fall slightly — SVRs are typically far above current fixed rates.
What is a tracker mortgage?
A tracker mortgage has an interest rate that moves in line with the Bank of England base rate, plus a fixed margin (e.g. base rate + 0.5%). When the BoE raises rates, your payments go up; when it cuts, they fall.
