Skipton Building Society is allowing customers who want additional borrowing to access all of its standard remortgage and retention products.
The building society currently only allows those seeking more borrowing access to a limited number of products at 75 per cent and 90 per cent loan-to-value (LTV).
Kris Brewster, head of products at Skipton, said that the change would enable customers to have a far greater selection of options.
The offering is a pilot, and she said it would be tweaked based on feedback.
Ms Brewster said: "Being a mutual, it is important we listen to our borrowers, and respond accordingly – doing so, and enabling home ownership, is something we have been doing for the last 165 years."
However, the additional borrowing facility is not available through brokers, only for direct customers.
