Brendan Gilligan, Mortgage Product Manager for Yorkshire Building Society, said: “We always try to offer our customers a range of mortgage options and good long-term value for money. Our rate reductions will offer borrowers with a range of deposits competitive rates and the security of knowing how much their mortgage repayments will be for the next couple of years, especially during this time of economic uncertainty.
