very expensive call out fee

The quality of their work is OK. However, I had to pay £120 for a job, where they pressed two buttons on the controller, and with the testing it took 10-15 minutes altogether, no tools or spare parts used at all. When I asked them why they charged such a high amount, they said it is their minimal charge. When I asked why I can't see this in their website, they said that they do not advertise their fees in their website. Be sure, that you call them only, when you are willing to pay at least £120, even if the problem is much smaller.

Wayne came out to see what was required and very quickly understood exactly what I wanted. The bath, old WC and sink were removed on day one and taken off site. The chippies were friendly and understood the requirement which they completed efficiently with no mess left behind. The electrician completed the new wiring in record time, again with no mess. The plumbers made sure that I was completely satisfied and again left no mess after them. Finally the new flooring looks fabulous and I cannot fault the tradesmen. All in all a great job and I would definitely recommend them. Rebecca was super efficient at answering my queries and a great help. I love my new utility / laundry room.

Do poor reviews serve any purpose?

Why are you looking at this review rated poor? Are your intentions to decide whether to use this company? Do poor reviews provide any useful purpose? If your mind is already made up then despite seeing adverse reviews and hearing of the cheap estimate it still leads one to ask what harm can it do? Well I ignored such reviews and still went ahead and appointed GasMonster of Cottenham. Here are some questions you should consider based upon our truthful and factual experiences. Would you choose a company that despite the Trades description act and the WHICH code of conduct still sent an unqualified convicted burglar to our home? A company that was subsequently referred to the WHICH compliance unit for investigation? A company whose quality of work was described in an independent RISA report as “not of an acceptable standard”? A company that was ordered by the Furniture and Improvement Ombudsman in October 2023 to pay us compensation? If the answer is still yes, then wasn’t reading this review rather pointless? So buyer beware or “Caveat Emptor” after all it’s your decision and your money.

We used Gas Monster to replace our 20 year old condenser boiler and hot water storage tank with a Combi Boiler. Their work was excellent the staff were professional and were very helpful and kept us informed throughout the installation. You wouldn't have known they had been here they were so neat and tidy (ie no mess or debris left behind). Highly recommended.

Gas Monster has recently replaced my boiler and installed a number of new radiators and thermostatic radiator valves with a full system powerflush. I was very impressed with the whole process from the initial survey by Wayne, the prompt answering of my questions and the politeness and efficiency of the engineer Dane and his apprentice Nathan. I had been dreading the mess and disruption the work would cause over a four day period but thanks to the professionalism of the operatives and the care taken by them it was much less stressful than I had anticipated. I am now looking forward to a warmer winter and a trustworthy company to service my boiler in the coming years.

Recently had a combi boiler installed by Gas Monster and the experience with them has been 5-star from start to end. Wayne was very knowledgeable and helpful. As this particular work required a new gas supply, he took the time to explain all the steps involved in the procedure and found an installation option that would suit my needs. The team that installed the entire system was skilled, tidy and courteous. They did a brilliant job in a surprisingly short amount of time, particularly Dayne who was also very patient in answering my numerous questions and in keeping me involved throughout the process. Friendly, professional and clean, I would highly recommend Gas Monster.

Extremely impressed by the whole service from Gas Monster when my boiler died during a cold week in February. I phoned around a few companies, and Gas Monster were the first to come out to have a look, the quickest to send me a quote (which was a fair price, and very similar to several other quotes), and were able to get the work done sooner than anyone else. The new boiler was fitted by Dane, who was very friendly and communicative, and did a brilliant job. I'll definitely use Gas Monster again.

Gas Monster replaced 16 radiators in my house earlier this year and did a great job. So when I decided to replace my 32-year-old boiler with a new more efficient boiler I had no hesitation in asking Gas Monster to do the work. Wayne took the trouble to visit my house so we could review the existing installation and decide on the best replacement. Reese and Jack with help from Wayne and electrician Simon have just completed the installation of a Worcester Bosch Greenstar 24Ri They arrived promptly at the agreed time and completed the work in one and a half days which was less than their estimate of 2 days. The new boiler and associated pipework was installed neatly. The flue outlet through the kitchen wall needed to be raised to suit the new boiler and Reese did a great job of cutting out the bricks where the old flue exited and replacing them with new bricks. He also explained the CO and CO2 tests and minimum and maximum load tests that he did when commissioning the boiler. During the work, they were polite, helpful and kind. On both days before they left they did a great job of cleaning up after their work. My new boiler is working very well. I am very happy with the work which Gas Monster has done for me and I highly recommend them.

On-time, efficient and friendly replacement of 16 radiators

Last week, Elliott and his colleague from Gas Monster Ltd replaced 16 radiators, installed a new pump and new three-way valve. They arrived to start work exactly at the time agreed and throughout the installation were hard-working, efficient, friendly and helpful. After the installation they performed a PowerFlush to remove corrosion deposits from the pipework and the boiler. The new metric sized radiators replaced heavily corroded 32 year old imperial sized radiators so changes to the pipework feeding the radiators were needed and they did this very neatly. The work was completed on time and I am very happy with their work. I can definitely recommend Gas Monster for heating and plumbing work in the Cambridge area. Many Thanks! Kind Regards Jerry

We were very impressed with the care taken by Will and his colleagues over the installation of our new boiler, which was also being relocated. We appreciated their considerate approach, their tidiness, the clarity of their communications and the quality of their work. They are strongly recommended.
