Remortgage Fixed Or Tracker
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
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 a lower fixed rate, borrowers can effectively manage their monthly payments without the fear of rising rates that could increase their financial burden. This stability is crucial for budgeting and long-term financial planning, making the fixed option the superior choice for those seeking predictability in their mortgage expenses. Choosing the fixed rate now safeguards against future rate hikes, ensuring consistent and manageable payments over the loan term.
The rate backdrop
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 set 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 monetary policy changes, potentially leading to higher payments in a rising rate scenario. Given the uncertainty surrounding future rate hikes, 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. Consequently, borrowers may find that the fixed option not only offers immediate savings but also shields them from future rate volatility.
Worked example
Assumptions (illustrative): £200,000 mortgage · Fixed 4.5% vs Tracker 5.24%
| Option | Monthly payment | After 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.
What to do next
| Your situation | Action | Why |
|---|---|---|
| Rates expected flat | Tracker likely cheaper | Effective tracker rate below fixed — no rate move needed to win |
| Rates expected to rise | Fix now | Each 0.5% rise erodes the tracker advantage |
