If you’re remortgaging, the choice between a fixed-rate and a tracker mortgage comes down to one question: how much uncertainty can you absorb? Fixed-rate deals give you a locked monthly payment regardless of what the Bank of England does next. Tracker mortgages follow the base rate up and down, meaning lower bills when rates fall but higher ones when they rise. Right now, with the rate outlook genuinely unclear, that distinction matters more than usual.
What Is a Fixed-Rate Mortgage?
A fixed-rate mortgage locks your interest rate for a set term, typically two, three, five, or ten years. Whatever the Bank of England does during that period, your monthly repayment doesn’t move. When the fixed term ends, you’re moved to your lender’s standard variable rate unless you remortgage again.
That predictability is the product’s main selling point. If you know your rate won’t change, you can budget around it. For homeowners with tight margins or those who simply dislike financial uncertainty, that’s worth paying a small premium for.
The trade-off is flexibility. Most fixed-rate deals carry early repayment charges if you want to exit before the term ends, which can run to several thousand pounds. If you need to move house or your circumstances change, those charges can make switching expensive.
Around 85% of UK borrowers are currently on fixed-rate deals, which tells you something about how most people weigh the certainty-versus-cost equation.
What Is a Tracker Mortgage?
A tracker mortgage sets your interest rate at a fixed margin above the Bank of England base rate. If the base rate is 3.75% and your tracker is set at base rate plus 0.21%, you pay 3.96%. When the base rate moves, your rate moves with it, usually from the following month.
The appeal is straightforward: when rates fall, you benefit immediately, without waiting for a new deal. Tracker mortgages also tend to carry fewer early repayment charges than fixed-rate products, making them easier to exit if a better deal appears or your plans change.
The downside is equally straightforward. If rates rise, your payment rises. There’s no floor unless your deal includes one, and not all do. According to UK Finance, around 591,000 borrowers are currently on tracker mortgages, representing roughly 7% of the market. That minority position reflects the fact that most people, most of the time, prefer certainty over the possibility of a lower rate.
The Rate Landscape Right Now
The Bank of England base rate currently sits at 3.75%, held at the June 2026 Monetary Policy Committee meeting. The best tracker rate on the market is 3.96% from Halifax, with arrangement fees of £1,599. The best two-year fixed rate for remortgagers is 4.35% from Bank of Ireland, with fees of £1,705.
The gap between those headline rates is real, but it’s narrower than it looks once fees are factored in. More importantly, the rate outlook has shifted considerably in recent months.
Earlier in the year, most forecasters expected the base rate to drift down gradually through 2026. That picture has changed. The conflict in the Middle East has pushed oil and gas prices higher, inflation came in at 2.8% in May 2026, and the Bank of England may now need to raise rates rather than cut them. UK rate forecasts for the rest of 2026 span a wide range, from 3.5% to 4.25%, which is an unusually large spread for a twelve-month window.
That uncertainty is the single most important context for your decision.
| Fixed-Rate Mortgage | Tracker Mortgage | |
|---|---|---|
| Interest rate | Locked for the term | Moves with Bank of England base rate |
| Monthly repayment | Fixed and predictable | Variable, rises and falls |
| Best current headline rate | 4.35% (2-year fix) | 3.96% (base rate + margin) |
| Average 5-year fix | 5.50% | N/A |
| Average 2-year variable rate | N/A | 4.49% |
| Early repayment charges | Usually yes, often significant | Often none or lower |
| Benefits from rate cuts? | No, until deal ends | Yes, immediately |
| Exposure to rate rises? | No, during the term | Yes, immediately |
| Typical market share | ~85% of borrowers | ~7% of borrowers |
| Best suited to | Certainty-seekers, tight budgets | Risk-tolerant borrowers, those expecting rate cuts |
The Danger of Doing Nothing
Before comparing fixed and tracker rates, it’s worth being clear about the alternative: doing nothing. If your current deal expires and you don’t remortgage, your lender moves you onto its standard variable rate. The average SVR is currently just below 6.49%, which is considerably higher than the best fixed or tracker deals available.
According to UK Finance, around 1.8 million fixed-rate mortgages are due to expire in 2026 alone, and an estimated five million homeowners will see their deals end by the close of the year. If you’re among them and you don’t act, the cost of inertia is significant. Both a fixed-rate deal and a tracker will almost certainly be cheaper than your SVR. The choice between them matters, but making any choice at all matters more.
Pros and Cons: Fixed-Rate
Pros:

Which Is Right for You?
As someone remortgaging now, your decision hinges on two things: your financial resilience and your view on where rates are heading.
If your budget has little room for an unexpected payment increase, a fixed-rate deal is the sensible choice. Locking in at 4.35% for two years isn’t cheap compared to rates from a few years ago, but it removes the risk of a nasty surprise if the Bank of England raises rates in response to rising inflation. The Office for Budget Responsibility has forecast that average mortgage rates will rise from around 3.7% in 2024 to around 5% by 2029 as more borrowers roll off historic low-rate deals, so locking in now could prove well-timed.
If you have meaningful headroom in your monthly budget and could absorb a rate increase of, say, 0.5% to 1% without serious strain, a tracker mortgage is worth considering seriously. The current spread between the best tracker and best two-year fix is around 0.39 percentage points. On a £250,000 mortgage, that’s roughly £50 per month. If the base rate falls even once before your deal ends, you’d recover that premium quickly.
The two-versus-five-year question matters too. Data from Q3 2025 shows that borrowers are now evenly split between two- and five-year fixes, having previously leaned toward five-year deals. The shift suggests many borrowers are betting on rates falling within two years and want the option to remortgage sooner at a lower rate. That logic is reasonable, but it assumes rates do fall, which is no longer the safe assumption it was six months ago.
If you’re also thinking about this from a landlord’s or investor’s perspective, the flexibility of a tracker can be particularly useful, since property plans often change. The financing guide for investment property covers how mortgage type interacts with investment strategy in more detail.
For most remortgagers with a standard residential mortgage and a household budget that doesn’t have much slack, the fixed-rate deal wins on balance. The rate gap between fixed and tracker is narrow enough that the certainty is worth the small premium, especially given the realistic possibility of a base rate rise in the months ahead.
Summary
The fixed-rate versus tracker decision is genuinely close right now, which is itself significant. When the gap between the two is large, the choice is easier. When it’s as narrow as it currently is, small differences in your personal circumstances tip the scales.
Fixed-rate wins for: borrowers who need payment certainty, those on tight budgets, anyone who expects rates to rise, and those planning to stay in their home for the full term of the deal.
Tracker wins for: borrowers with financial headroom, those who believe rates will fall further, anyone who values the ability to exit cheaply, and those whose property plans may change within the next year or two.
What neither option wins for is inaction. If your current deal is expiring, the SVR waiting for you is materially worse than either. Understanding the difference between how the UK lettings and mortgage market works and how rate decisions affect your repayments is the starting point, but acting on it is what actually saves you money.
Frequently Asked Questions
For most remortgagers, a fixed-rate mortgage is the safer choice right now. The rate gap between the best fixed and tracker deals is narrow, and the risk of a base rate rise has increased due to rising energy prices and inflation. Borrowers with meaningful financial headroom who can absorb payment increases may find a tracker worth considering.
If you don’t act when your fixed or tracker deal expires, your lender moves you onto its standard variable rate. The average SVR is currently just below 6.49%, which is significantly higher than the best available fixed or tracker rates, making inaction the most expensive option of all.
Many tracker mortgages carry few or no early repayment charges, so switching is often straightforward. Fixed-rate mortgages usually carry early repayment charges that can run to several thousand pounds if you exit before the term ends, so always check the specific terms of your deal before making a move.
A tracker mortgage is set at a fixed margin above the Bank of England base rate, so when the MPC changes the base rate, your mortgage rate changes by the same amount, usually from the following month. The current base rate is 3.75%, and any rise would feed directly into your monthly repayment.
Data from Q3 2025 shows borrowers are now evenly split between two- and five-year fixes, having previously favoured five-year deals. Many are betting on rates falling within two years, but that assumption carries more risk than it did earlier in the year given the uncertain inflation outlook.
