Boiler installed by this company a couple of years ago and follow up servicing as good as the installation. Company email service reminder (good price), efficiently book appointment, turn up on time and provide invoice by email within minutes. Been lucky enough to have my original installer come to do each service and he is lovely: polite, efficient, friendly and helpful. This year he also gave extra advice on the most efficient operation of the boiler. I have no hesitation recommending this company.

The heating engineer that I had used for over 40 years retired and I was apprehensive about finding a replacement to service my boiler properly. Gareth Williams Heating were a local company with excellent reviews so I contacted them. They answered the phone immediately and their engineer was able to call the same day, exactly on time. He did a thorough service, including the filter and condensation bottle, for a very reasonable price and left me confident that I had made the right choice. I am more than happy to recommend this company, I only wish that others did business in the same way.

Had to organise a new gas boiler and room heater for my mother, who lives 450 miles away from me, so finding a trustworthy and competent heating installer was paramount to me. The work required was extensive, as my Mother's existing installation dated back to 1974 and was, quite frankly, a mess. Gareth Williams provided me with a detailed quote, did the job when he said he would, answered all my questions promptly and went above and beyond what I expected in sorting out supplementary electric heating for me too. From quotation thru completion, Gareth Williams heating Ltd have been professional, helpful and have inspired total confidence. I would recommend them as your first choice of heating installer if you live in the Newport area. Outstanding.

Replace back boiler with combi boiler
Customer Service
Quality

We were looking to replace an ageing back boiler with a modern combi boiler. Gareth visited us and came back with his quotes within a couple of hours. The work was carried out the following week. Our old back boiler, gas fire, airing cupboard tank and loft cistern were all removed quickly and the new boiler and associated pipework installed with the minimum of fuss. This work took 2 full days. The morning of the third day was taken up by a power flush of the system. So job completed within 2 and a half days. I can't speak highly enough of the 2 lads who did the work - Dan and Lorenzo. They were professional, competent, friendly and kept us informed throughout about the work they were doing. After they had finished they explained how the system worked and how to use the controls. They filled in all the associated paperwork and sorted out the payment details. They were fantastic and a credit to Gareth Williams Heating Ltd. I look forward to renewing acquaintances in a year's time when we have our annual boiler service. Thank you Gareth, Dan and Lorenzo for making the whole project simple and straightforward throughout. I would wholeheartedly recommend this company for any work of a similar nature.

Boiler service. The engineers turned up on time, they were polite and professional and left the site clean and tidy. I had also asked for a quote for some additional work, Daniel took the time to explain the differences between products to enable me to make an informed decision. I have agreed to the quote and arranged a date for the additional work. A very good experience from start to finish
