Ian Ramsden, TSB mortgages director, said: “Our research shows that millions of homeowners up and down the country are worried about an increase in the Bank of England’s base rate and the knock on effect it will have on their mortgage repayments.
“People looking for stability at a great value will definitely benefit from Fix and Flex.
“All the advantages of a great rate, fixed over the long term yet the flexibility to move after five years should their circumstances change.”
According to TSB’s own research over half (55%) of mortgage holders are worried about paying more when base rates rise.
Indeed two-thirds (65%) of UK homeowners are prepared to take out a long-term fix, yet a higher number (72%) are concerned about having to pay high early repayment charges should they change their deal.
