Rising mortgage rates are the "biggest new threats" to long-term pension saving, according to research by retirement specialist Standard Life. A homeowner coming to the end of a fixed-rate deal of around 2.50% – a common rate in 2021 – now faces an average rate of 5.63%. On a £500,000 repayment mortgage over 25 years, monthly repayments will jump by £866.
Impact on Household Budgets
Mike Ambery, retirement savings director at Standard Life, said: "That is putting real pressure on household budgets at a time when many people are already contending with higher day-to-day expenses, and may lead them to reassess their wider finances."
Putting that £866 into pension savings over 25 years from age 34 – the average age of a first-time buyer in the UK – would add £268,000 to the overall pension pot, the analysis said.
Sharp Spike Even in Recent Months
The price jump is stark even for those who committed to their fixed-rate just months ago. Mortgage rates have spiked from an average of 4.91% at the start of 2026 to 5.63% today. This equates to a £213 difference a month on a £500,000 mortgage over 25 years.
Ambery said: "For many people, buying a home is a key part of their long-term financial security – but, as mortgage costs rise, households may have less flexibility to save elsewhere, including into their pension. If someone needs to adjust their finances, reducing pension contributions may feel like a quick way to free up income."
Maximising Pension Value
He encouraged homeowners to ensure they are getting as much value as possible from what they can afford to save, pointing out that pensions benefit from tax relief. For example, an £80 pension contribution is topped up to £100 for basic-rate taxpayers. "If you pay higher- or additional-rate tax, you can usually claim back more through your self-assessment tax return or by contacting HMRC, reducing the true cost further," he added.
