Amanda Bryden, head of Halifax Intermediaries and Scottish Widows Bank, said: “There is increasing confidence in the market and rates are falling. These cuts will be a boost to anyone looking to get on or move up the housing ladder.”
Other high street lenders, like HSBC, Natwest, TSB, Santander and Barclays have also lowered their rates in recent days.
Building societies, smaller banks and specialist lenders have also joined the rate cutting wave as swap rates, which dictate mortgage pricing, started to fall at the end of last year.
