Homeowners could save thousands by using cash boost from National Insurance cuts to overpay mortgages

  • Santander UK shows how homeowners could save thousands by putting the National Insurance (NI) cut towards overpaying their mortgage
  • A worker on a salary of 拢30,000, who put the full NI saving of 拢29 towards their mortgage would save 拢7,405 in interest and shave over a year off their mortgage term
  • Santander customers overpaid more than 拢903 million on their mortgages online or by mobile in 2023, up 78% from 拢508 million in 2022听

With many workers benefitting from a pay-packet boost this month as a result of the NI cuts, data from Santander shows how putting some, or all of this extra cash towards mortgage overpayments could save homeowners thousands over the life of their mortgage.

Calculations from the lender show that a worker earning 拢30,000 a year will see an extra 拢29 a month in their January 2024 payslip. If they repurposed all 拢29 towards overpaying a 25-year mortgage of 拢200,000 at 4.7% they would save 拢7,4051 in interest and be mortgage free more than a year earlier than planned.听

Even committing just part of a NI saving could make a difference, with Santander accepting overpayments from as little as 拢10 per month, which on the same mortgage would save more than 拢2,500 in interest and shave four months off a customer鈥檚 mortgage term2.听

Graham Sellar, Head of Business Development, Mortgages at Santander, said: 鈥淢any people will shortly see the first benefits of the National Insurance cut in their pay-packet. For those able to, using this extra money each month to overpay on their mortgage could reap huge benefits in the long run, saving thousands and helping them achieve the mortgage-free dream sooner than expected.鈥

Those earning between 拢60,000 and 拢100,000 a year will see an NI saving of 拢63 a month, which if put towards a 拢200,000 mortgage would save 拢15,0933 in interest and take over two years off the term.听

Santander makes it easy for mortgage customers to make overpayments through its online and mobile portal. In 2023, Santander customers overpaid a total of 拢903 million through the lender鈥檚 online and mobile channels, an increase of 78% on the previous year.听

In the first week of 2024 alone, 18,198 overpayments were made online, with customers making use of the reset 10% overpayment allowance which sees most mortgage lenders allow customers to repay 10% of their outstanding capital each year before any early repayment charges are incurred.听
