The mutual says it has struck a deal with the broker-only arm of the Surrey-based business, founded in 2012, which has over 3,000 intermediary members across the UK.

The unit developed from offering specialist BTL advice to working in residential, second-charge, bridging and commercial and semi-commercial markets.

Leek United intermediary team manager Laura Allcock says: “We have confidence that our criteria for both residential and BTL markets offer real solutions to partners and their clients.

“Whether it is our later life lending approach, loan to values of up to 95% including new builds and flats, no reliance on credit scores to make decisions for us and our extensive experience of both BTL and residential lending, we believe Dynamo is the perfect fit to support our continued growth.”

Dynamo for Intermediaries mortgage club director Cat Armstrong says: “It isn’t one specific piece of the Leek’s criteria or product set, rather their blended offer, desire to be the best lender in their space and our aligned values that make them the ideal fit for us.”

Last month, CHL Mortgages was reappointed to the panel of Dynamo for Intermediaries following its return to lending earlier this year, after pulling back from new BTL lending in 2008.

The two businesses had previously worked together over several years and the move in June brings CHL’s products to a wider range of advisers through Dynamo’s mortgage club. 

While in February, Staffordshire-based Leek United returned to portfolio buy-to-let and interest-only markets. It said it had returned to these markets after “a number of months” following conversations with partners.
