The loyalty mortgages will launch on 1 September.
Customers with any of Barclays’ current accounts, including Premier, Additions and Graduate accounts, will be eligible for the discounted rates. They must have a minimum of £800 credited to their account in each of the last three months when they apply for the deal.
Mortgages include a two-year fixed rate at 2.95% up to 70% LTV, 0.54% below the standard offer.
Products up to 80% LTV, rates are 4.19%, which includes a discount of 0.19%.
Andy Gray, head of mortgages for Barclays, said: “We are always looking at how we can offer the most competitive mortgage rates we can and the most deserving people for these are our existing customers. Our current account customers will now always have access to discounted rates in our range, as a reward from us to them for their loyalty.”
