Plumbers' merchant Plumb Center and the Association of Plumbing & Heating Contractors (APHC) have begun a pilot partnership project recommending APHC members to customers of its Leeds branch.
The scheme will see Plumb Center recommending APHC members to customers and offering APHC members a discount.
John Thompson, APHC chief executive, said: "This is a great boost for our members in the Leeds area, and for the Association as a whole."
Alan Stevenson from Plumb Center said: "We would like to welcome more APHC members to become new Plumb Center customers and I hope the combination of the service we offer and the discounts available to members will give them every reason to use Plumb Center."
The APHC-Plumb Center partnership launched on 14 April at the Plumb Center Bathrooms showroom in Leeds.
