The choice between a fixed vs variable mortgage is one of the most consequential decisions any borrower makes. Get it right and you either lock in a rate that holds as rates rise, or you benefit as rates fall. Get it wrong and you pay more than you needed to for years.
In May 2026, with the Bank of England base rate at 4.25% following gradual cuts from its 2023 peak, and with analysts expecting further reductions over the next 12 to 18 months, the decision is more genuinely difficult than it has been at either extreme of the rate cycle. Both fixed and variable products have a credible case. This guide explains what each type is, what the current numbers look like, and how to think through the decision for your specific situation.
What a Fixed Rate Mortgage Is
A fixed rate mortgage locks your interest rate for a defined period — typically 2, 5, or 10 years. Your monthly payment stays exactly the same regardless of what happens to the Bank of England base rate or your lender’s standard variable rate during that period.
The main advantages:
- Complete certainty over your monthly payment for the fixed term — no surprises, no adjustments
- Protection if rates rise — if the base rate increases during your fix, you continue paying the lower locked rate
- Easier budgeting, particularly for first-time buyers or those on tight margins
The main disadvantages:
- Early repayment charges (ERCs) — if you need to exit the deal before the fixed period ends, you typically pay 1 to 5% of the outstanding balance
- If rates fall significantly, you are locked into a higher rate and may pay more than you would on a tracker
- At the end of the fixed period, you revert to the lender’s standard variable rate (SVR), which is almost always significantly higher — typically 7 to 8% — making timely remortgaging essential
Current rates. As of May 2026, the best rate on a 2-year fixed rate mortgage is from HSBC at 4.45% (60% LTV, £999 fee). Average 2-year fixed rates sit around 4.36% and average 5-year fixed rates around 4.39%, with some lenders offering 5-year deals from 3.72%.
What a Variable Rate Mortgage Is
A variable rate mortgage does not lock in your rate — it can go up or down during the term. There are three main types.
Tracker mortgage — directly linked to the Bank of England base rate at a set margin above it. If the base rate falls by 0.25%, your tracker rate falls by 0.25% automatically. With the base rate currently at 3.75%, a “Base Rate + 1%” tracker puts you at 4.75%. Trackers typically carry no or minimal early repayment charges, giving you flexibility to switch products if the rate environment changes.
Standard variable rate (SVR) — the lender’s default rate, applied when a fixed or tracker deal ends. SVRs are typically the most expensive way to borrow — currently around 7 to 8% across most lenders. Nobody should intentionally choose an SVR; it is what you revert to if you fail to remortgage when a deal ends.
Discount mortgage — a rate set at a specific margin below the lender’s SVR for a defined period. Moves up and down with the SVR rather than directly with the Bank of England base rate. Less transparent than a tracker and less popular.
The 2026 Rate Environment: What It Means for the Decision
Many analysts suggest we are at or near the peak of the rate cycle, and if you believe rates will continue to fall throughout 2027 and 2028, a variable tracker with no exit fees might be a smart tactical move.
The honest framing is that nobody knows with certainty where rates go next. The arguments on each side are:
Case for fixing:
- Certainty is genuinely valuable — particularly for buyers on tight budgets who cannot absorb higher payments
- 5-year fixed rates are currently marginally lower than 2-year rates, reflecting lender expectations that rates will fall but not dramatically
- If inflation reaccelerates and the Bank raises rates again, a fix provides protection
Case for tracking:
- If the base rate continues falling — markets expect further cuts through 2026 and into 2027 — a tracker drops automatically with each cut
- No ERCs on most tracker products means flexibility to switch to a fix if the rate environment changes
- The current spread between tracker and best fixed rates is narrow enough that the flexibility argument has genuine weight
2-Year Fix vs 5-Year Fix
For buyers who have decided to fix, the choice between 2 and 5 years is its own decision.
2-year fixed:
- Lower initial rate historically, though in 2026 the gap between 2 and 5-year rates is minimal
- You remortgage sooner — if rates fall further over the next two years, you benefit at remortgage. If rates rise, you are exposed sooner.
- More flexibility — useful if you might move or significantly change your circumstances within five years
5-year fixed:
- Longer payment certainty — five years without a remortgage decision or rate uncertainty
- Currently marginally cheaper than 2-year products on average, unusually inverting the historical pattern
- Better suited to buyers who value stability and are unlikely to move within five years
The decision often comes down to your view on where rates will be in two years. If you believe rates will be materially lower by 2028, a 2-year fix gives you a faster route to those lower rates. If you are uncertain, the marginal rate advantage of 5-year deals and the additional certainty makes them the safer choice for most buyers.

When Each Option Makes Most Sense
Fixed rate suits you if:
- You are on a tight monthly budget and cannot absorb payment increases
- You value certainty over potential savings
- You are buying at the edge of your affordability
- You plan to stay in the property for at least the fixed term
Variable (tracker) suits you if:
- You believe rates will fall further and want to benefit automatically
- You want flexibility — the ability to move or overpay without ERC penalty
- You have financial headroom to absorb higher payments if rates rise unexpectedly
- You are planning to move within the next two to three years and want to avoid ERC costs

The Standard Variable Rate Trap
One point worth repeating explicitly: when a fixed or tracker deal ends, you automatically move to the lender’s SVR. At current levels of 7 to 8%, this can add hundreds of pounds per month to your payment on a typical mortgage. The solution is simple — begin the remortgage process six months before your deal ends. Many lenders allow you to lock in a new deal up to six months ahead at no cost, so you roll straight from one deal to the next without spending a day on the SVR.
Setting a calendar reminder for six months before your deal expires is the single most valuable mortgage admin task you can do.

Conclusion
In May 2026, both fixed and variable mortgages have a credible case. Fixed rates offer certainty and protection against any rate reversal. Tracker mortgages offer automatic benefit if rates continue falling and flexibility without ERCs. The right choice depends on your budget flexibility, your view on rates, and how long you plan to stay in the property.
A whole-of-market mortgage broker can model both options against your specific numbers and identify the products most suited to your circumstances — not just the headline rate but the total cost over the likely holding period. London Stays can connect you with trusted advisers at every stage of the buying process.
Frequently Asked Questions
Is it better to fix or track your mortgage in 2026?
There is no single right answer. If rates continue falling as expected, a tracker with no ERC benefits automatically. If you prioritise certainty and cannot absorb payment increases, a 2 or 5-year fix provides that regardless of what happens to the base rate. The best choice depends on your budget flexibility and rate outlook.
What happens when a fixed rate mortgage ends?
When your fixed term ends, you automatically revert to the lender’s standard variable rate — typically 7 to 8% at current levels. This can add hundreds of pounds to your monthly payment. Start the remortgage process at least six months before your deal expires to avoid landing on the SVR.
Are 2-year or 5-year fixed rates better in 2026?
Currently the difference between average 2 and 5-year rates is minimal, with 5-year deals marginally cheaper than 2-year. If you expect rates to fall significantly in the next two years, a 2-year fix gives you a faster route to a lower rate at remortgage. If you value stability, the 5-year provides longer certainty at broadly the same cost.
