The Society will increase the fee from up to 0.37% to up to 0.5%, bringing it in line with similar fees on the market.
Martin Richardson, Leeds Building Society’s general manager – business development, said: “We have been working very closely with our intermediary partners on how to develop the service and products we offer through them to support our appetite for growth.
“We have the funding and the capacity within our plans to continue to increase our lending on buy-to-let mortgages and are pleased to be able to make this change to our fee structure.
“Intermediaries are a key element of our growth strategy. We have been investing heavily in enlarging our team of corporate account and regional development managers and our underwriting capacity as lending through brokers has risen.”
