Data from Santander revealed that increasing numbers of homeowners overpaid on their mortgage in the first four months of 2026.
The lender said its customers overpaid their mortgages by a total of £894 million during this period – from January to April 2026 – as they tried to prioritize balancing long-term savings on interest against increased day-to-day living costs.
It saw an increase of more than £200,000 in regular and one-off payments compared to the same period last year.
Most lenders allow mortgage borrowers to overpay up to 10% without facing penalty fees, and Santander is no exception.
Graham Sellar, head of Santander Brokers, said: “We know that many headlines paint a bleak picture for homeowners, as rising borrowing and living costs tighten finances.
“That’s why seeing overpayments of more than £200,000 from customers in the first four months of 2026 is a really encouraging sign that, even with stretched budgets, homeowners are taking confident steps to reduce what they owe, save interest in the long term, and build more security for the future.”
Customers can make a one-off overpayment or via a regular monthly payment starting at £10 a month, Santander said. They can use the app, go online or make a payment over the phone.
It also has online Overpayment calculator To help customers understand the impact an overpayment can have on their mortgage in terms of interest saved and how quickly they can pay off their mortgage.
What are the financial benefits of overpayments?
Santander said that by making minimum overpayments of £10 a month on a £250,000 principal and mortgage at a typical rate of 4%, a customer could reduce the term by three months and potentially save £2,117 in interest payments.
For those able to pay an extra £50 per month, this would save a year and six months of term and generate a potential saving of £9,975.
For those paying an extra £100 a month, this saving could rise to £18,619 and reduce the time it takes to repay by two years and 10 months.
