Our Trusted Customers

Hilton and this company was recommended to me by a friend and I have been very impressed with his company Quantam Gas Engineering.I had my ageing Vaillant boiler replaced and the whole experience was painless. Hilton was so responsive, explained everything so well and took great care in my flat protecting the flooring and surfaces during the installation.My new heating system is so much better than expected and I have a much better idea about how to make the best use of it (effectively and efficiently) to meet my needs. I can strongly recommend this company.

Hilton Shaw replaced our boiler with a more advanced and efficient system. He and his colleague provided a quick, thorough and professional service. We were kept informed of progress and they cleared all mess during and on completion of the job. We were given clear instructions on the new controls and were pleased and impressed with all aspects of their work. We would recommend them without hesitation.

Hilton installed our new boiler and thermostat and it was a very positive experience all round. He is highly knowledgeable and a very experienced engineer. Our boiler needed to be fitted to a very tight space and his recommendations on which system to go with were top-notch. Every step of the installation process was clearly explained. He is completely reliable and he and his team did a very thorough job, completing the work to a very high spec. Everything was left clean and tidy after the installation was finished too. We are very happy with the result and now have a much more energy-efficient and effective heating system. Highly recommend!

This is the second time I’ve worked with Hilton. I was as impressed second time as I was first time and would recommend his services to anyone. In London it’s hard to find high quality engineers who are also responsive, professional and trustworthy. Hilton is all these things.

I needed to replace the expansion vessel in my Bosch boiler. I contacted QGE on an evening and they were able to source the part and complete the installation the day after. This was done last April after the COVID situation started and they took extreme care to maintain all the preventive measures while completing the job. I have not had any problem (this review is posted 3 months after the repair was done) and will definitely call them again for any similar issue in the future ! Thank you !

Hilton is the ultimate professional : he explained everything in lay mans terms and went over and above the work required to fit a new boiler. He outlined all options available and ensured we were happy with choices made. We subsequently used him for a problem with a shower which again he fixed in a timely and fist effective manner. It’s s joy to finally find a brilliant gas engineer/ plumber, who not only provides great value for money but is equally very personable and trustworthy. Highly recommended!

Hilton Shaw of QGE is my go to heating engineer. I have worked with him on 30 private executive rental properties and in a private capacity on two new heating installations. He will be installing a new eco heating system in my recently purchased home. Hilton pursues future trends, by means of professional courses which keep him updated on global industry best practices. He is a can do individual. I'm delighted to highly recommend him.

Had one of these old boilers from the ice age, a Worcester Bosch boiler. Already had all possible parts replaced but finally died and no hot water at all. Looked for professional boiler installation in Totteridge and found Quantum Gas Engineering Ltd. Professional, transparent and gave me option for 0% finance too. The engineers arrived bang on time and carried out what they already initially communicated with me. They left the home in immaculate condition too and reassured me if there were any issues to let them know. It's been 3 months on, so decided to apply this review now. No issues at all whatsoever, we had a Viessmann boiler installed and it kicks in all the time, it's a smart boiler so we're not used to this, how we've been missing out! We can set the times ourselves and not worry about wasting energy. It also heats up hot water instantly and pumps it out faster when we have showers. Thank you to the guys at Quantum, honest, straight up and amazing service.

Hilton and his team have been absolutely fantastic. We had some complicated plumbing work done at our house ranging from external drainage through to internal heating reconfiguration. The communication was excellent throughout, they turned up exactly when they said they would, used carpet protectors and cleaned up afterwards. Hilton even responded to an issue on a Sunday night. Unreservedly recommend.

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!
