Jemma Smith, the Chelsea’s product manager, said: “There is still uncertainty over how the base rate will move in the coming months and years so some borrowers prefer to fix their mortgage and avoid any surprises.
“The cuts we are making will help to keep borrowers’ repayments as low as possible and either help them on to the housing ladder or make owning their property more affordable.
“There has been a great deal of movement within the mortgage market recently as a result of falling swap rates and we are making sure customers benefit by keeping our wide range of mortgages as competitive as possible.”
