Old boiler needed taking out, plus hot water cylinder. All work carried out efficiently. New Bosch boiler installed. Graige Mastin was the gas engineer & he was excellent. I cannot recommend him enough. Polite, tidied up & extremely hard working.

Installation of Worcester Combi boiler, with power flush and energy saving controls. Very pleased with the work. Engineer explained what he was doing and answered all my questions in words I could understand (being in my mid eighties) was a lot to learn.

Replacement boiler installed. From the outset, all staff were impressively pleasant and competent. Unexpected difficulties were overcome cheerfully and efficiently--all in marked contrast to my experience with other traders in this line.

Had a new combi boiler fitted which was done both to time and cost. All staff involved, the receptionists, the person who came and estimated the job, the person who fitted the boiler, the support staff including those who did the electrical work and repaired the the damage caused by the fitting were all very friendly, professional and extremely competent in their approach to the work. Unfortunately two small installation problems, which were nothing to do with the boiler itself, occurred within a week of the new boiler being fitted, both of which were fixed the day after I reported them. To say am I am pleased with the work this company has carried out for me is an understatement. I just wish the professionalism and work ethic of this company was reflected in other companies I have dealt with, even the boiler fitter turned up half an hour before the time he was scheduled to start, so I have no hesitation in recommending this company to anyone else wanting this kind of work carried out.

Replace our hot water tank. The company seems well organised with good paperwork (printed and email) and tracked the progress of the quote to completion well. Fitted us in at short notice as a gap came up in their schedule. Took excellent notice of the house by laying sheets on the stairs to prevent carpets being marked.
