Requiring a new boiler is not the best situation but dealing with KAS made it a pleasure. Sam the surveyor was very knowledgeable and amenable. Ross the installer was an excellent tradesman very friendly and working late into the evening to make sure that we had a working boiler before he left, even though he could have left at 5pm and completed the next day.A slight problem with the controller was addressed by Ross within a couple of hours being reported.We would recommend KAS More...

I have been very pleased + totally satisfied with the recent services I have had from KAS Energy. Matt came last week + did a gas safety check, he was very thorough, polite and helpful. Then he noticed a radiator was going rusty so he noted it + KAS got in touch, the radiator was fitted today . Very speedy service. Matt came + did the job today, again he was very pleasant, put plastic down to walk on, worked hard + got the job done. He is always happy to answer any questions you have + I felt happy + comfortable to have him in my house.I would recommend KAS Energy and Matt to anyone, I’m sure you’d be more than happy with them both. I’m very happy with the service I received 🙂👍 More...

Had a new boiler fitted by KAS Energy. The boiler was fitted in one day with no mess whatsoever. The fitter was professional and really hard working. I cannot praise this company high enough from pricing the job to fitting. We had 3 other quotes prior to giving the job to this company. We are so pleased we made the right choice, even though it was late the fitter took his time on explaining the working s of the boiler. First class job, 100% , 5 starsP k Parker More...

Great experience all round. Initial contact was good and company came straight back, organised a survey quickly. Excellent competitive quote given following survey, which was very professionally done by Sam. Great follow up by Kim and date arranged for work. Alex, the fitter, arrived as arranged, and worked quickly and systematically to install the new boiler and associated work, giving good on site advice when needed and was very respectful to us the home owners. All work done as stated on the quote and price was as per the quote with no hidden extras. All in all a very professional job from start to finish and would thoroughly recommend to anyone thinking of a boiler installation. Thank you KAS. More...

The KAS representative physically attended to survey the house and old boiler, checking water flow rate etc before leaving a written quote at the end of the visit. This is something I prefer to the other over the phone quotes I had which leave me wondering if additional works might be required for ‘unforeseen’ circumstances. The quote was very competitive compared to another local company and an online franchise.Kim speedily replied to a lot of my queries and provided other quotes on different boilers without pressuring me to make a speedy decision.This particular project required replacing two Combi boilers in the property and the work was planned to be carried out over two days. In fact the engineer who arrived on time, Alex, was so competent and knowledgeable about the boilers I had chosen that he fitted both boilers on the same day. Attention to safety was a priority and one of the old flues was extended at no extra cost. After commissioning both boilers and final checks on gas pressures etc Alex explained the system and controls to my tenants rather than just handing over instruction manuals, which was much appreciated.The work was carried out to a neat high standard and with due regard to respecting the property. On completion the house was left as clean and tidy as when Alex arrived.Would highly recommend this company More...

We recently had KAS Energy replace our old central heating and hot water system with a new combi boiler, and the whole experience was excellent from start to finish. Kim was very responsive and kept us well informed throughout the process. Sam, the owner of KAS, is a genuinely nice person who came to our property himself and carried out a detailed survey before providing a clear and fair quote. The installation was completed by John Walker, who did a fantastic job – professional, tidy, and very friendly.After the installation, I had a small issue adding the new boiler to the Hive app. Although this wasn’t KAS Energy’s responsibility, Sam went above and beyond by personally visiting and helping to sort it out, even contacting Hive customer service on my behalf. That level of care and commitment is rare to find these days.I’m extremely happy with the service from KAS Energy and wouldn’t hesitate to recommend them to anyone looking for a reliable, professional, and customer-focused company.

Our Experience dealing with Kass Energy Plumbing and Heating was one of the most easy and straightforward no fuss, or complicated , issues from beginning to end of our Boiler beng fitted . Sam arrived , and after five minutes of him arriving we knew instantly he was a very genuine and sincere person , Sam asked us about what had happened with our old boiler and what we wanted , he went to look at what we needed and explained everything and advised us what would be good for us , also when We spoke to Kim his Wife on the telephone she was soo very helpful explaining all what was to happen and about how the financial side of it all would work . They booked us in very quickly and Sam told us a young man named Alex would be fitting our boiler , Alex was amazing he rang us to arrange his visit and came at the time he had arranged Alex introducing himself to us and got on straight away and never stopped we just suppled him with drinks , he explained everything to us before he left .
