We called Ryan on a recommendation to look at our hot water system which had stopped working. Ryan came as soon as he could and though the problem was a mystery he figured it out quickly and came back the next day with the right parts to fix. He was efficient, courteous and helpful. His price was fair and we will use him again. Thanks Ryan. Ina Norrman

Tennant reported that they had no hot water. I contacted AHS, Ryan, who attended, and by the next day two parts were replaced and hot water was up and running. All were happy with the great service provided

We had a new boiler installed and our old radiators upgraded, the plumbing engineers came on time and everything was very well managed. We are so impressed with the quality of the work and recommend Assert Heating Services highly.

Our boiler is not as new as other makes but your team provided an excellent service. Assert Heating Services reassured me that they could take on any kind of heating system problems, and they didn’t disappoint. Great work, many thanks.

Having been recommended by a friend, we had no hesitation in asking Assert Heating Services to install a new boiler and central heating system for us. The two engineers that came carried out the work to a very high standard and we are delighted with the results.
