The range has a follow-on rate of 2.49 per cent above the Bank of England Base Rate, lower than the lender’s current homemover variable rate of 3.59 per cent.
As a result of the lower follow-on tracker rate, first-time buyer applications will be stressed at a lower rate of 5.6 per cent instead of 6.6 per cent.
“This will help more first-time buyers to be able to buy the home they want, while ensuring doing so remains affordable for them over the full life of their mortgage,” TSB said.
The range includes just one two-year fix at up to 60 per cent LTV with a rate of 1.39 per cent and £999 fee.
