Fixed vs Tracker Mortgage: Which Should You Choose in 2026?

mortgages May 28, 2026

Verdict

The fix (4.5%) is cheaper than the current tracker (5.24%).

Confidence: High

Break point: Tracker wins only if BOE cuts rates by 0.74pp or more.


The rate decision

Bar chart: fixed £1,112/month vs tracker £1,197/month
Monthly payment: fixed 4.5% vs tracker 5.24% (illustrative)
The tracker starts cheaper at current BOE rates — but every 0.5% rise erodes that advantage and the fixed rate gives certainty.

The fixed rate of 4.5% is clearly more advantageous than the current tracker rate of 5.24%, as it provides payment certainty and eliminates the variability risk associated with fluctuating interest rates. By locking in the lower fixed rate, borrowers can effectively budget their monthly payments without the fear of rising costs, which can occur with a tracker that may increase in response to market conditions. This stability not only enhances financial planning but also protects against potential future rate hikes, making the fixed option the superior choice for those seeking predictability in their financial commitments.

The rate backdrop

Bar chart: fixed 4.5% vs tracker 5.24%
Fixed rate vs tracker effective rate (illustrative)
The fixed rate locks in certainty; the tracker passes every BOE move directly to your monthly payment.

In the current Bank of England base rate environment, where the base rate is at 4.5%, opting for a fixed-rate mortgage is more financially advantageous than a tracker mortgage, which is currently at 5.24%. This disparity arises from the inherent tracker risk, as tracker rates are directly linked to the base rate and can fluctuate with future monetary policy changes, potentially leading to higher payments if rates rise further. Given the uncertainty surrounding inflation and economic conditions, locking in a fixed rate at 4.5% provides stability and predictability in monthly payments, making it a more cost-effective choice in the current climate. Thus, the fixed rate not only offers a lower initial cost but also shields borrowers from the volatility associated with tracker rates.

Worked example

Assumptions (illustrative): £200,000 mortgage · Fixed 4.5% vs Tracker 5.24%

OptionMonthly paymentAfter 0.5% rise
Fixed (4.5%)£1,112£1,112 (unchanged)
Tracker (5.24%)£1,197£1,257

At current rates, the fixed is cheaper by £86/month. A 0.5% BOE rise would move the tracker to £1,257/month.


When this flips

This flips only when BOE rates move by more than 2.0pp in the direction that disadvantages the current choice. The certainty value of the fixed rate at 4.5% is high.
