Tracker vs Fixed-Rate Mortgage 2026: Which Is Cheaper?
Tracker mortgages move with the Bank of England base rate; fixed deals lock your rate for 2–5 years. In 2026 with base rate at 4.25% and swap rates falling, the tracker vs fixed decision is finely balanced. Full analysis.

Mortgage monthly payment calculatorHow a tracker mortgage works
A tracker mortgage directly follows the Bank of England base rate:
- Rate formula: BoE base rate + lender margin.
- Adjustment: Every time the BoE changes the base rate, your rate adjusts at the next payment date.
- Term: Usually 2 years, but lifetime trackers (which track for the full mortgage term) also exist.
- ERCs: Most tracker deals have no early repayment charges — a significant advantage.
What is the Bank of England base rate?
The base rate is set by the Monetary Policy Committee (MPC) 8 times per year. In May 2026 the rate is 4.25%, following cuts from the peak of 5.25% in August 2023. Markets are pricing in further gradual cuts through 2026/27.
How a fixed-rate mortgage works
A fixed-rate mortgage locks your interest rate for the initial term (typically 2 or 5 years):
- Rate: Set at the time you take the product. Does not change during the fixed period.
- Reversion: At the end of the fixed term, you move to the lender's Standard Variable Rate (SVR — typically 6–8%) unless you remortgage.
- ERCs: Fixed deals almost always have early repayment charges (typically 1–5% of the outstanding loan) if you exit before the term ends.
- Certainty: Monthly payment is predictable throughout the fixed period.
Head-to-head: the key differences
| Feature | Tracker | Fixed |
|---|---|---|
| Rate certainty | ✗ — varies | ✓ — locked |
| Payment predictability | ✗ | ✓ |
| Early repayment charges | Usually none | Usually 1–5% |
| Benefits from rate cuts | ✓ — automatically | ✗ — locked in |
| Protected from rate rises | ✗ | ✓ |
| Currently cheaper (May 2026) | ✗ | ✓ |
| Flexibility to switch | ✓ — easy | ✗ — costly |
The break-even calculation
For a tracker to be cheaper than a fix over 2 years, the base rate needs to fall sufficiently. Here's the maths on a £250,000 repayment mortgage over 25 years:
| Scenario | Tracker (base + 0.75%) | 2-year fix (4.5%) | Tracker saving |
|---|---|---|---|
| BoE unchanged at 4.25% for 2 years | ~£1,460/mo | ~£1,388/mo | -£72/mo (tracker worse) |
| BoE cuts to 3.75% in 6 months, stays | ~£1,390/mo avg | £1,388/mo | ~£2/mo (roughly equal) |
| BoE cuts to 3.25% in 6 months, stays | ~£1,315/mo avg | £1,388/mo | £73/mo better |
| BoE cuts to 3.00% in 6 months, stays | ~£1,283/mo avg | £1,388/mo | £105/mo better |
Monthly payments are approximate and illustrative. Assumes interest-only simplification for comparisons.
The tracker starts winning comfortably only if the base rate falls to around 3.75% or below within the year. Markets in May 2026 are pricing roughly 1–2 further cuts by end of 2026.
Worked example — £200,000 mortgage
Sarah is remortgaging a £200,000 balance over 20 years remaining.
Option A: Tracker at base + 0.8% (5.05%)
- Monthly payment: ~£1,327.
- If base rate falls 0.5%: ~£1,274/month.
- If base rate rises 0.5%: ~£1,381/month.
- No ERC — can switch at any time.
Option B: 2-year fix at 4.4%
- Monthly payment: ~£1,249.
- Fixed for 24 months — no surprises.
- ERC ~2% if exiting early (£4,000 on £200k).
In this example, the fix saves Sarah £78/month (£936/year) compared to the tracker at current rates. The tracker only wins if rates fall more than 0.5%.

Try your own numbersWho should choose a tracker?
Trackers tend to suit borrowers who:
- Believe interest rates will fall significantly within the next 12–18 months.
- Want flexibility to switch deals without paying an ERC (e.g., expecting a large lump sum, planning to sell).
- Are comfortable with monthly payment variability.
- Have a large offset savings pot that reduces effective rate sensitivity.
Who should choose a fixed rate?
Fixed rates tend to suit borrowers who:
- Prioritise payment certainty for budgeting.
- Are stretching affordability and cannot absorb a rate rise.
- Expect rates to stay stable or rise.
- Plan to stay in the property beyond the fixed term.
- Are first-time buyers who need predictability while settling in.
The 5-year fix case in 2026
Five-year fixes are currently available at only slightly lower rates than two-year fixes (swaps curve is relatively flat in 2026). A 5-year fix offers:
- Certainty through to 2031.
- Protection against any re-escalation in rates.
- Typically lower rate than a 2-year fix in this environment.
The risk: if rates fall substantially by 2028, you're locked into a higher rate until 2031 (or pay the ERC to exit).
Remortgaging and product transfers
- Product transfer: switching to a new deal with your existing lender (often no solicitor needed, faster).
- Remortgage: switching to a new lender (can access wider market, may get a better rate, requires legal work).
If your fixed deal is ending in the next 3–6 months, you can typically lock in a new rate now (even before the current deal ends) without paying the ERC. Many lenders allow you to reserve a rate up to 6 months in advance.

Frequently asked questions
Is a tracker mortgage cheaper than a fixed mortgage in 2026?
It depends on where interest rates go. In May 2026, with the Bank of England base rate at 4.25%, typical tracker mortgages charge base rate + 0.4–0.9%, giving effective rates of 4.65–5.15%. Two-year fixes are available at around 4.3–4.8% and five-year fixes at 4.1–4.6%. Trackers are currently more expensive than fixes, but would become cheaper if the base rate falls by 0.5–1%+.
What is a tracker mortgage?
A tracker mortgage has an interest rate that tracks the Bank of England base rate by a fixed margin (e.g., base rate + 0.75%). If the base rate rises by 0.25%, your rate rises by 0.25% too. Most trackers have no early repayment charges, meaning you can switch to a fixed rate if conditions change.
Can I switch from a tracker to a fixed mortgage?
Yes, in most cases. Most tracker mortgages have no early repayment charges (ERCs), which is one of their key advantages. You can switch to a fixed deal at any time — either with your current lender (a product transfer) or by remortgaging to a new lender.
What happens to a tracker mortgage if the Bank of England raises rates?
Your monthly payment rises immediately from the next payment date. On a £200,000 tracker mortgage, each 0.25% rate rise adds approximately £25–£30/month. A 1% rise adds around £100–£120/month. This makes payment budgeting harder than with a fixed rate.
