Coast2Coast Construction Services will be a third strand of the group, which also includes Coast2Coast Energy and Coast2Coast Renewables.
The group began in 2013 as a solar panel installer and expanded into insulation and biomass boiler installation.
Commercial director Andrew Gore said: “We have skilled people such as electricians, heating engineers, plasterers and bricklayers who can supply the needs for just about every job in and outside the home you can think of. Basically we are now offering a bespoke service and we are basically a one-stop shop for all internal and external works.”
Coast2Coast Construction is based at group headquarters in Tonmawr.
