The funding contract between Aldermore Bank and Keystone has ended after three years.

During that period, the arrangement originated nearly £200m in loans.

From 1 July, a ‘Loyalty Range’, funded by Aldermore, will be offered exclusively to existing Keystone customers who are nearing the end of their initial rate.

Keystone will continue to offer buy-to-let mortgages via its Solutions Range, funded by Lancashire Mortgage Corporation.

It added that a new funding partner for a new Classic Range will also be announced on 1 July.

David Whittaker (pictured), managing director of Mortgages for Business, which owns the Keystone brand said: “It’s been a really exciting venture which would not have been realised had it not been for the vision and determination of Rob Lankey, former managing director of the commercial mortgages division at Aldermore.

“We are deeply grateful to him, David Stiff and their colleagues for such commitment to the project.”

Charles Haresnape, managing director of mortgages and commercial lending at Aldermore, added: “We are grateful to David and his team for supporting us with the Keystone venture and wish them all the best for the future.”
