We’ve been running on an oil boiler which has been limping along for the last two years. Finally took the plunge to switch to gas. Chelmsford Plumbing and Heating have helped nurse the old boiler and their commitment and quality of work led us to ask them to quote replacing with gas. They provided guidance on the type of boiler and work to be done, explaining clearly everything that would happen with a competitive quote to remove the old boiler, tidy up the pipework and brickwork, fit the new boiler, including a power flush, and remove the oil tank from the garden. Job took nearly 3 full days, each day the team were prompt, organised and tidy. Throughout the work they kept me appraised of what was going on and each evening the house was left tidy. All in all, the whole end to end process was simple, efficient and confidence inspiring. For such a big job it couldn’t have gone more smoothly. Would absolutely recommend CPH.
