About Us

Our Story

We are an intermediary only lender owned by The Property Business Group Limited. Keystone was created by brokers for brokers in 2007, with a sole purpose to provide specialist lending at a time that this wasn’t widely available.

Since its inception we have been through three different joint ventures but finally became a lender in our own right in 2018 and doubling in size over the years. 

Brokers are and always will be at the forefront of what we do and we pride ourselves on ensuring we are providing the best possible solutions and service.
