Called for a hot water issue after we noticed some water dripping from the overflow. Came out same day, fixed the problem, very polite and even followed up the following day that we had no further issues. Thank you!

Hilton & Quantum Gas Engineering were recommended to me by a friend and I am forever grateful. They are thorough, professional and a delight to have dealings with. They are the only people we want to work on our boiler.
5 stars for Hilton and team who installed a new (replacement) system gas boiler. It wasn't an easy instal as we wanted to relocate it and that meant reconfiguring all the primary pipework and installing a new flue in quite a tricky location. The iniital instal was prompt and efficient, clean and tidy and the boiler fired up within 2 days. All good on the hot water and c/h but there was a niggling issue with the control of the u/f heating circuit which took a number of return visits before it was resolved. Not a major issue but it was rather frustrating - for us and Hilton as it wasn't obvious where the problem was. But Hilton kept at it with good grace and eventually sorted it. So now all good. Thanks to all at Warm & Cool London (aka Quantum G E)

Not impressed that the engineer forgot to reopen the valve that makes the hot water taps work. Also he expected me to know how to lower the pressure.

When I got an error message on my boiler and it stopped working, Warm and Cool London saved the day. They sent Ntoris straight away and best of all, kept me informed about his arrival. He then sorted it out quickly and efficiently and clearly knew what he was doing. I will definitely use them again if I have problems.

Ntoris from Quantum Gas & Engineering came out and quickly sussed the problem - electrical. He fixed it quickly and efficiently and checked out the entire boiler while here. As always with Quantum, the service was great. They look after two properties for us and have always been great to work with.

The team of Warm and Cool was extremely professional and very respectful. They made sure our carpet and staircase wouldn't get damaged so they put plastic on the floor (I know it seems a normal thing to do but after trying with several other companies we can say that this is so rare!). We feel extremely happy with their service so far and would definitely recommend them!

We have used Warm and Cool London (QGE LTD) on many occasions over the last few years. They have done a lot of work in the Grade I Listed St.Stephen's and have dealt with complicated heating issues to the highest standard.In our school generally they have done excellent work in gas and heating areas, they are always responsive and punctual, and overall a pleasure to work with.

I was quoted £130 for a service, but was charged £420 (and no service was carried out). This despite sending photos and a video of the immediate issue (a leaking valve). When I politely queried this I was sent a vague email by Hilton that didn't really address my question, nor did it lay out in any detail what was wrong with the boiler. Two followup emails asking for a firm quote for the rest of the work that needed to be done were ignored. So I'm now in a position of having to get a new engineer in to rediagnose the problem and provide a fresh quote in addition to the needed service, with associated additional costs.

Was recommended by an electrical contractor. Was very impressed with the quality of the work, responsiveness and punctuality. Happy to use again and have arranged a return visit to service our boiler. Have also used on another property and happy to recommend either personally or to a managing agent. Hilton is a good guy and is very trustworthy along with his colleagues

I have used this company many times now and have been so impressed on every occasion. I would highly recommend this company to anyone who is looking for a top-quality reliable service. 10/10

Hilton & Ntoris did a fantastic installation job on a new Viessmann system boiler, replacing my old boiler. Full of praises for their professionalism, tidiness, on time, and total after care once all was installed. Any issues of teething problems of new system was overcome promptly, help was only a call away.Although I have used this company happily in the past for minor repair works, with this huge installation job the service was excellent all round, their knowledge is exceptional.I will be using them for many years ahead and would highly recommend them.

Hilton first helped me by finally fixing an unreliable underfloor heating system which had defeated numerous other plumbers and electricians. Since then I have used him to replace and maintain my gas boiler. Excellent service and technical understanding.
I like Quantum so much that they are now servicing not only my boiler but my son’s and my daughter’s boilers. There’re a really good team.

Quantum have serviced my boiler for the last few years. They are reliable, arrive on time and are happy to answer questions/explain things. Very happy with their work.
I have worked in the construction industry for over 16 years and Hilton is by far the most competent plumber I have ever dealt with. He is punctual, efficient and very knowledgeable. He installed my boiler with no hassles and I will be continuing to use his services and recommending him to my clients and of course family and friends. Thanks for the great work!
