Miguel Sard, managing director at Abbey for Intermediaries, said: “These rates, available exclusively to our Key Accounts, are back by popular demand. Both homebuyers and remortgagers can take advantage of these great products and we expect there to be very strong demand from borrowers over the coming week.
“We are also pleased to support intermediaries and their clients with further rate reductions of up to 0.30% across our range. We are committed to supporting the intermediary market with great products and service, and these enhancements to our range follow the launch earlier this week of our popular new document upload tool for intermediaries.”
