Fixed vs Tracker Mortgage: Which Is Better in 2026?
The best 5-year fixed and tracker rates are now just 0.03 points apart — 4.38% vs 4.35%. With pricing this close, the real decision isn't which is cheaper, it's which risk you're willing to carry. Here's the honest breakdown.
The best five-year fixed rate on the market right now is 4.38%. The best five-year tracker is 4.35%. For the first time in years, the two headline numbers are close enough to be a rounding error — which means the fixed-vs-tracker decision in 2026 isn't really about price anymore. It's about what happens to the number you didn't lock in.
Key Takeaways
Top best-buy rates have nearly converged: around 4.35–4.38% for the best 5-year tracker and fixed deals, and 4.66%+ for 2-year fixed — a much tighter gap than the "tracker is always cheaper" reputation suggests.
Fixed means your rate is set for the whole term regardless of what the Bank of England does next — payment certainty, at the cost of missing out if rates fall.
Tracker means your rate moves directly with the Bank of England base rate (currently 3.75%) plus a fixed margin — real savings if rates fall or hold, real risk if they rise.
The Bank of England has flagged that the base rate could climb toward 4.5–5.25% by 2027 if inflation pressure persists — a tracker taken today could cost meaningfully more before the deal ends.
Early Repayment Charges (ERCs) are the hidden variable: fixed deals often lock you in with a charge that can run to thousands of pounds if you leave early, while many trackers carry little or none — flexibility that matters if your plans might change.

What the Numbers Actually Tell Us
The headline story right now is how close fixed and tracker pricing has become. A leading 5-year tracker sits at base rate + 0.60%, currently around 4.35%, while a leading 5-year fixed comes in at roughly 4.38% — a gap of just 0.03 percentage points at the very top of the market. On shorter terms the picture is similar: a competitive 2-year fixed is available around 4.66%, against a no-fee 2-year tracker near 4.74%.
That near-tie is unusual. Trackers have historically priced in a discount to compensate borrowers for taking on rate risk — lenders needed to make the "cheaper but riskier" trade-off obviously worth it. When fixed and tracker pricing sit this close together, the market is effectively saying the near-term risk of the base rate moving either way is genuinely uncertain, not a one-directional bet.
How Each One Actually Works
Fixed rate mortgages lock your interest rate for a set period — typically two or five years — regardless of what the Bank of England does in the meantime. Your monthly payment is identical from the first month to the last of the deal. According to MoneyHelper's guide to mortgage interest rate options, this predictability is the main reason most UK borrowers choose fixed deals — it turns your biggest monthly outgoing into a known quantity.
Tracker mortgages move directly with the Bank of England base rate, currently 3.75%, plus a fixed margin set by the lender — for example, "base rate + 0.60%." If the base rate rises, your payment rises within weeks; if it falls, your payment falls just as quickly. You're accepting variability in exchange for the possibility of paying less than a fixed borrower over the same period.
The Real Risk With a Tracker Right Now
The Bank of England held its base rate at 3.75% in September 2026, but the vote was split — and the Bank itself has acknowledged that persistent inflation pressure could push rates toward 4.5% by early 2027 and higher again by late 2027 if conditions don't ease. A tracker taken out today at base + 0.60% would move in lockstep with any of those increases — a rise from 3.75% to 4.5% alone would add roughly £40–£45 a month in interest on a typical £250,000 tracker mortgage, before accounting for further rises the Bank has flagged as possible.
That's not a reason to rule out a tracker — it's a reason to stress-test your own budget against a genuinely higher payment before choosing one, not just the payment at today's rate.
The Real Cost of a Fixed Deal: Getting Out Early
The number that catches fixed-rate borrowers off guard isn't the rate — it's the Early Repayment Charge. Most fixed deals carry an ERC if you remortgage, move house and don't port the deal, or pay off the mortgage before the fixed term ends. On a £250,000 mortgage with a typical 3% ERC, leaving early can cost in the region of £7,500 — a cost that only shows up if your circumstances change faster than you expected when you signed up. Trackers, by contrast, frequently carry little or no ERC, which is the flexibility side of the trade-off that the headline rate alone doesn't capture.
💡 Model both scenarios before you decide: run your mortgage balance through our Mortgage Calculator to compare a fixed payment against a tracker at today's rate — and again at a stressed, higher rate — so you're choosing based on your actual numbers, not just the headline percentage.
Three Questions That Actually Decide This
How long do you realistically plan to stay in this property or deal? If a move, sale, or remortgage is plausible within the term, a tracker's lighter ERC matters more than its rate.
Could your budget absorb a genuinely higher payment without stress? If a base-rate rise toward 4.5–5.25% would meaningfully strain your monthly budget, that's a strong signal toward the certainty of a fixed rate, even at a near-identical starting price.
Are you choosing based on today's rate, or today's rate plus where it's likely to go? With fixed and tracker pricing this close, the decision has shifted from "which is cheaper" to "which risk are you more willing to carry."
What This Means for You
When fixed and tracker rates sit within a few hundredths of a percentage point of each other, as they do right now, the traditional "tracker is the cheap, risky option" framing breaks down. The real decision is about which side of the risk you'd rather hold: the certainty of an unchanging payment for the term, or the possibility of paying less if rates hold or fall — balanced against a real, Bank-acknowledged chance they don't.
What You Should Do Next
Compare live fixed and tracker rates for your actual LTV and loan size, not just headline best-buy figures
Check the specific Early Repayment Charge on any fixed deal you're considering, and what triggers it
Stress-test a tracker against a base rate of 4.5–5.25%, not just today's 3.75%, to see if your budget holds
Be honest about how likely you are to move, sell, or remortgage before the term ends
If you're still unsure, a shorter fixed term can split the difference — less rate risk than a tracker, less long-term commitment than a 5-year fix
Fixed and tracker mortgage rates have converged to nearly the same starting price in 2026, which means the choice between them now comes down to risk tolerance and flexibility rather than which one is obviously cheaper. A tracker rewards you if the Bank of England holds or cuts rates, but exposes you if it doesn't — and the Bank itself has said further increases are a real possibility. A fixed rate protects you from that, at the cost of a real Early Repayment Charge if your plans change. Run both scenarios through your actual budget before deciding, not just the headline rate.
FAQ
Is a tracker mortgage cheaper than a fixed rate right now?
Not by much — at the top of the market, the best fixed and tracker rates are within a few hundredths of a percentage point of each other, a far smaller gap than trackers have historically offered.
What happens to my tracker payment if the Bank of England raises rates?
Your payment rises in line with the increase, usually within weeks. The Bank has flagged a real possibility of the base rate climbing toward 4.5–5.25% by 2027, which would increase a tracker payment accordingly.
How much could an Early Repayment Charge cost me on a fixed deal?
It depends on the specific charge and your remaining balance, but a typical 3% ERC on a £250,000 mortgage can cost in the region of £7,500 — always check the exact terms before signing.
Can I switch from a tracker to a fixed rate later if rates start rising?
Often yes, though it depends on your lender and deal — many tracker mortgages allow switching to a fixed product during the term, sometimes with conditions. Check this specifically before choosing a tracker if it's part of your plan.
