Job very well done!

Will was great - clever, fast, efficient, effective, tidy, polite, pleasant. What more could one ask for!? He actually arrived early but phoned to check first if that was OK - it certainly was. Booking the job and paying for it online was quick and easy too. The job was fitting a new water pump to a very old system with ineffective isolation valves.

Quote did not include all I asked for. When fitting an additional and absolutely pointless stop valve (instead of replacing one which drips) they have managed to cut through my kitchen waste pipe. I have only noticed three weeks later. Thank goodness it was not a gas pipe. They have failed to repair a bath scratch they have caused. I have paid in full only because their extremely obnoxious email was making me sick and I wanted to put this behind me.

Gas Monster carried a new boiler installation (Worcester-Bosch 8000) and also a new gas pipe to provide adequate pressure. The job was completed over 2 days (plus one day for power flushing). The engineer was professional, respectful, worked quietly on both days. We only had one night without heating but that was a small price to pay for such a great job, in the middle of the winter as well. I have trusted Gas Monster for servicing my old boiler which was really poorly installed and maintained by another company. Their installation of the new boiler was impeccable, hassle-free and although it is still early days, I have peace of mind and confidence that they can fix any possible future problems. Highly recommended!

We recently had our boiler and cylinder replaced by Gas Monster. They came recommended to me and their quote was very competitive. This was a big job and our fitter Brian worked tirelessly for the week. The work was completed in a highly professional manner and I would not hesitate to recommend Gas Monster.

After 30 years it was time to refurbish our downstairs cloakroom. We had various ideas and we were happy that we were listened to, understood and suggestions made to make even more improvements, providing that they would fit in with our budget. We received full itemised costings and a work schedule, which suited us perfectly. Everything was done on time and according to budget. We were very impressed with the professionalism and helpfulness of the Gas Monster team. Any minor issues that surfaced were explained to us and excellent solutions found. We couldn't be happier.

Gas Monster was recommended to us. Old back boiler replaced by a new combi boiler. Our installer, Reiss, worked brilliantly - his work was impeccable. He kept us informed of what he was doing at each stage of the job. He was very kind, polite and just got on with his work to a very high standard and if we had any questions, he took the time to answer without hesitation. The work was finished on time. An old radiator decided to leak rusty water on the day the work was finished - I made a phone call and they came back straight away to isolate it (nothing to do with the work). We are now having old radiators replaced by them. I would highly recommend Gas Monster, 100%.

New Combi Boiler & Thermostatic Shower

Old original boiler was 30-40 years old. It was getting noisy and less efficient and spare parts hard to get hold of. Gas Monster produced a quotation for us for a new boiler more efficient combination boiler and a new thermostatic shower, to replace our old electric shower, previously installed by Wayne. Boiler was moved from the kitchen to the airing cupboard on the landing, with minimal disruption. Had a new Lyric T6R WiFi thermostat installed. Old flue removed and pipework removed from kitchen and hole in wall bricked up. Tiles were replaced in the bathroom where old shower was. New flue had to be installed through the loft and roof. Straightforward, tidy, efficient and courteous service. Job completed in 5 days on time and as expected. we have used Wayne and his team for years to service our previous boiler. Also replaced our toilet & shower over the years. Highly recommended. Thank you to Wayne and Gas Monster team.
