Dougfield Plumbers Supplies, Plumbplus Supplies and J & Bs are all to become members of the Cemco Merchant Network from 1 May.

All three merchants focus on heating, plumbing, fittings and sanitary ware, and discussions have taken place to ensure they “fit comfortably within the Cemco portfolio”, according to chairman John Parker.

He continued: “The addition of [these] excellent new member[s] now boosts the membership to 30, enhancing Cemco’s position to being the best organised, most committed, independent buying group in the country.”
