Up to 2.5 million homebuyers may be paying hiked interest payments as a result of falling onto lender SVRs, according to Tesco Bank.
The firm says the average monthly SVR is around 4.39 per cent, while the average two-year fixed rate is 1.95 per cent.
Tesco Bank adds that these customers “could be over-paying on their mortgage by up to £274 a month”.
The firm says this is a problem because one-third of home buyers would need to reduce their spending if interest rates rose by 0.25 per cent.
Tesco Bank managing director David McCreadie says: “Our goal is to reward the loyalty of our customers.
“Our latest home buyers research illustrates that customers continue to face many challenges when buying a home and so we give them a little help by offering our competitive rates when their fixed rate term comes to an end.”
Earlier this year digital mortgage broker Trussle called for a ‘mortgage switch guarantee’ to tackle the issue of mortgage prisoners trapped on lender SVRs.
