Andy Gray, Managing Director of Mortgages for Barclays, said: “We know how important a low monthly payment is for borrowers and we are doing our bit to help people save money with the launch of some of the lowest residential remortgage rates in the market.
This is another great example of Barclays helping more customers to achieve savings when buying a first home, remortgaging or those looking to take their next step on the property ladder.”
