We replaced our gas boiler with an electric one. They were very efficient punctual and cleaned up after finishing every day. They were also very helpful with explanations and tips on how to get the best efficiency from the new boiler.

We had a new boiler and portable thermostat installed by Gas Monster and were really pleased with the work. The team were professional throughout and even made sure I knew when the work was likely to be loud so as not to disrupt my child's naps. They were really helpful throughout and addressed any questions I had about the quote/new boiler.

We had a combi boiler fitted, the old hot water tank and pipes removed, an old asbestos flue removed and a new gas hob connection put in. Gas Monster were great. They were punctual, friendly and tidy and didn't disturb us while we were working from home. They were also well organised, arranging all the various necessary trades people. We were very impressed and would highly recommend them.

Gasmonster did an amazing job fitting a beautiful new bathroom and installing a new boiler for us. All the tradesmen were very professional and friendly. I couldn't be happier with the result, and the price was very reasonable. Will definitely be using them for any future work and would recommend to anyone!

New combi boiler installed and old boiler and tank removed. The inspection and quotation process was pleasant and very informative, and an email quote was received the same day. The installers arrived when they said they would and worked carefully and cleanly, leaving our house tidy each evening. The work was completed ahead of the time quoted. I would definitely choose them again if I have further work that needs doing.

New Boiler System
Customer Service

We had a new boiler system with new radiators put in. We have used Gas Monster before many years ago and we found them reliable, they turned up when they said they would and if they were running late, they informed us. The company has grown since then however we were delighted to find that they still are professional, that they explain everything that is going to happen, and keep you informed as to progress, and above all, are reliable. We've had a few things done around the home and I'm afraid to say the one thing we are let down on by other independent companies is reliability, and we've had many headaches over this, so it was a breath of fresh air to find an independent company that acted with professionalism. Brian fitted our new boiler and he was very happy chap who was very clean and tidy, when he had completed the work he vacuumed everywhere and made sure it was all clean and tidy before leaving. Gas Monster set up the new warranty for us and explained what to do if anything should go wrong. We are definitely recommending them and would use the again.

Gas Monster advised on the repair and upgrade of our Uponor underfloor heating system. They gave us options for improving the controls for the system and we then used them to install an upgraded controller and to carry out replacement of some components of the system. The engineer who came (Steven) was very polite, efficient and helpful. He explained the technical aspects clearly. I would recommend Gas Monster.
