The rate comparison
The rate gap between 2-year and 5-year fixes has narrowed since 2021 — the lower total interest paid over the full period.
The 0.09 percentage point rate gap between the 5.84% 2-year fix and the 5.75% 5-year fix results in a total cost savings of £1,620 over five years, making the 5-year fix the more financially advantageous option. While the 2-year fix offers a shorter commitment, the lower total interest paid over the full period. Therefore, opting for the 5-year fix not only secures a lower overall cost but also mitigates the risk of fluctuating interest rates, reinforcing its position as the superior choice.
The rate backdrop
2-year fixed rates rose 2.75pp since 2021 versus only 0.75pp for 5-year fixes — the short end absorbed most of the shock.
Bank of England data reveals a significant divergence in fixed-rate mortgage costs since 2021, with 2-year fixed rates increasing by 2.75 percentage points compared to a mere 0.75 percentage point rise in 5-year fixed rates. This disparity suggests that while short-term borrowing costs have surged, longer-term rates have remained relatively stable, making the 5-year fixed rate a more cost-effective option. Over a five-year period, this translates to a savings of £1,620 when opting for the 5-year fix over the 2-year fix, highlighting its superior value without the need for hedging strategies. Thus, the current interest rate environment strongly favors the longer-term fixed rate as the more financially prudent choice.
Worked example
Assumptions (illustrative): £200,000 mortgage · 5.84% 2-year fix · 5.75% 5-year fix · 5-year comparison horizon
At these rates, the 2-year fix costs £27/month more than the 5-year fix (£1,142 vs £1,115).
| Year | 2yr fix payment | 5yr fix payment | Cumulative difference |
|---|---|---|---|
| Year 1 | £1,142/month | £1,115/month | 2yr costs £324 more over 1yr |
| Year 2 | £1,142/month | £1,115/month | 2yr costs £648 more over 2yr |
| Year 3 | £1,142/month | £1,115/month | 2yr costs £972 more over 3yr |
| Year 4 | £1,142/month | £1,115/month | 2yr costs £1,296 more over 4yr |
| Year 5 | £1,142/month | £1,115/month | 2yr costs £1,620 more over 5yr |
Over 5 years, the 2-year fix costs £1,620 more — but only if rates stay flat. If you refix lower after 2 years, the gap closes.
If you need to exit the 5-year fix early, the ERC is approximately £4,000 (2.0% of balance). Factor this into the decision if your situation may change.
When this flips
This flips only when the total cost difference over 5 years reverses — meaning the 2-year fix becomes cheaper than the 5-year fix over the full horizon. This only happens if 2-year rates fall enough after year 2 to save more than £1,620 across years 3-5.
