T J Plumbing installed a new combi boiler in my loft which included running new pipes from the gas in the garage, up to the loft. They took out an existing boiler, tank in airing cupboard and drained and re sited 2 massive water tanks in the loft. They also boarded the floor on the part of the loft where the old tanks were situated. The following day the system was given a complete power flush and radiators checked. At a later date I decided to have thermostats fitted on all my radiators. This was a lot of work and Terry spent the hottest day of the year in my loft working away in the unbearable heat. Terry and his team were excellent. Very professional, polite, exceptionally clean and kept me informed of the progress as they went along. I am really happy with my new combi boiler and wouldn't hesitate to recommend T J Plumbing for professional, high class work .
