We had a leaky pipe going into the back of our washing machine. The engineer was efficient replaced the valve and provided a good explanation of the problem – would recommend
review by Pat (January 2023)
We had a leak in a pipe caused by us. As usual Gas Monster responded quickly and within 24 hours the problem was mended. The engineers worked very tidily, efficiently, professionally and were extremely courteous. We have been using them for years now and wouldn’t go anywhere else.
review by Petra (January 2023)
Boiler Service very quick and efficient
review by Willo (January 2023)
We were delighted and relieved when an engineer came quickly to bypass a frozen condenser on a very cold day. When a second engineer came a few days later to restore the piping, he didn’t wear the usual plastic overshoes and left mud patches on our stair carpet. Otherwise, all good.
review by Phil (December 2022)
Very prompt and efficient diagnosis and solution of boiler waste problem
(December 2022)
Yesterday someone came to fit a new thermostat. The engineer arrived on time, left the area tidy and explained the device’s workings to me.Today the boiler failed because of a frozen condensate pipe. An engineer came out very quickly to make a temporary fix until the pipe thawed. Altogether very pleased with the service – and grateful to have it all working again.
review by Phil (December 2022)
Pipes frozen, employee arrived as I was speaking on the phone.
(December 2022)
we have used Gasmonster on several occasions and have been very pleased each time. The latest was overheating of radiators, which was worrying and potentially very expensive. As they were in our area and it was urgent they came almost immediately and the repair was done on the spot and problem was solved. Thank you Wayne and Rebecca.
review by Isabob (December 2022)
I have used Gas Monster four times over the last two years and highly recommend them. Rebecca and Fiona are efficient and helpful when I need to make an appointment for work to be done.James performed a very thorough boiler service yesterday and gave very helpful and informative answers to my questions. He explained why he needed to clean the magnetic filter even though it had been done 3 weeks before. He sent me a Certificate immediately after the work was completed.Three weeks ago, Reese diagnosed and replaced a failed air trap in the heating system and replaced a faulty toilet syphon.He was polite, helpful and efficient. He arrived at the agreed time and the work was completed to a high standard.I am very happy with Gas monster and will definitely use them again.
review by Jerry B (November 2022)
An excellent boiler service from a competent and thorough engineer. No corners cut and some extremely helpful advice given too. Will certainly be using Gas Monster again. A definite cut above previous boiler services.

(November 2022)
Utterly brilliant team. Give great advice and guidence. Never try to sell you things you don’t need and always do what they say is best for you.
review by Jim Thomas (November 2022)
GasMonster did a boiler service for me recently, and just last week came back to remove the remains of an old warm-air heating unit from my house. It contained asbestos, so they took care to work safely and engaged a dedicated removal-and-disposal contractor on my behalf, and dealt with all the necessary work.I’d recommend them for the services I’ve had from them, and I’d be surprised if they couldn’t handle any domestic heating engineering task, at this point.
review by Dan Summers (November 2022)
Regular servicing of our gas fire over several years. The team is always reliable, helpful and friendly. Highly recommended.
review by Trish (November 2022)
Excellent work. Very happy.

Boiler service. Very prompt, polite, and tidy certificate issued immediately. Would recommend and will use again.
review by Robertson (November 2022)
Excellent service from booking to completing work, we had a boiler service but also given a lot of helpful advice about our system and heating.Cannoy be faulted.
review by Milton (November 2022)
Came on time and the service went well as far as can tell. The workmanship at the boiler was tidy. They’ve always been very good. However, on this occasion the engineer completely altered the settings on the controller – times, dates, heat level etc – and didn’t even warn us they all needed to be reset. It spoilt an otherwise excellent record.
review by Phil (November 2022)
Boiler serviced today by Gas Monster. Quick, efficient and friendly answered all my questions re radiators, most economical way to heat the house etc patiently and clearly. Great service.
review by Debbie (November 2022)

review by John (April 2022)
Gas Monster has provided helpful, timely and efficient care for our heating system, which wss based on a quite old boiler, for a number of years. We recently needed to have a new boiler and Gas Monster did an outstanding job in replacing the boiler. Once again, their work was efficient and timely. The work was done in a considerate manner and they did a great job cleaning up as well. In addition, they made an additional repair to another part of the system at no additional cost.
review by VF (April 2022)
Pleased with the en-suite shower door job but damage to adjacent bedroom wall and tiles in bathroom.
(April 2022)
We’ve had Gas Monster over a few times to service our boiler and carry out different jobs to our water tank, boiler, leaky toilet and kitchen tap. They are very efficient and tidy and even if they have to return to finish a job, always complete the work to a high standard. No complaints so far and I would highly recommend them to anyone.

We had a new boiler and thermostatic shower installed in June 2020 by Wayne and his team. We are extremely happy with the work carried out. Over the years we had have a new toilet as the cistern cracked and an electric shower. This fixed by Wayne. We have used Gas Monster for many years and would highly recommend them.
review by Jonathan (June 2021)
We have used Gas Monster on several occasions (mainly Will) from smaller jobs (replacing a tap) to bigger ones (full installations of a shower room and a bathroom). We have always been satisfied with their high-standard work. . Also after installing a new boiler, services in the two following years have been done competently. They were also happy to look at small issues and always identified them and redressed them properly. In three words: very competent, reactive and pleasant.
review by Will (June 2021)
Gas Monsters came highly recommended by a friend, and I would pass on the recommendation without hesitation. They always explain what they are doing and what needs to be done very clearly. And they get to it and have always fixed the problem! Thank you.

review by Sarah T (May 2021)

Friendly, professional and flexible company to deal with. They have completed such excellent work to a high standard, listened to exactly what we wanted and when I asked advice about an unrelated DIY query, the engineer gave advice and even went the extra mile by correcting it which was a great surprise when we returned. Would definitely recommend making these guys the first port of call for any gas and plumbing work.

review by Vicky (February 2021)
It’s the first time I’ve used Gas Monster and I’ll certainly use them again.

A great job. Very highly recommended.

review by Harstoner (November 2020)
Gas Monster are a wonderful team of skilled professionals, who work brilliantly together to provide an excellent service. We had them work in our home for a week, replacing cloakroom fittings including a shower and radiator, along with reconfiguring old internal pipework and installing a new boiler. They adhered to covid-safe practice throughout the work, whilst also keeping us informed of the progress and checking our preferences at certain stages of the process. We have always found Gas Monster to be very reliable, professional and competent. This latest work is no exception.We have no hesitation in recommending them.
review by Louise (November 2020)
I have used Gasmonster for years now. I find them friendly and reliable and always do a good job. Recently they replaced my shower, a dramatic improvement on the old one.
review by Eddie (September 2020)
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. He made sure to clear up all his tools etc each day he was here. 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%.
review by Suzanne (July 2020)
Removed the water tank, installed a new combi boiler, & replaced radiators. Brilliant job done; from initial consultation to completion, so pleased with everything. My thanks to Wayne, Harry, & the whole team.
review by Sarah (July 2020)
Wayne and his Gas Monster team replaced our 40 year old water cylinder, was very easy from start to finish and the workmanship and politeness of the fitter was excellent, would highly recommend them for workmanship and competitive costs.
review by Simon R (July 2020)
Replaced our boiler, hot water tank and all the controls. Did a fantastic job; very professional, considerate and friendly. Highly recommended.
review by Dunc (July 2020)
Old boiler was 30-40 years. 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. Old flu removed from kitchen and hole in wall bricked up. Tiles 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 his team & not forgetting Rebecca.

review by Terry (April 2020)
excellent professional workmanship & curtesy & respect for customer property
review by Dr Alastair Durrant (March 2020)
Have used Wayne and his team previously to repair our shower and tanks, recently our boiler failed and the team sorted us out with a new boiler, helped provide us with heaters as we had no heat at all all, Brian turned up each day on time, worked hard all day, leaving the house clean and tidy at the end of the day. He even put up with a 4 month old puppy!!! The work was completed to a very high standard. Thank you so much
(March 2020)
Old boiler failing. Gas Monster engineer advised it had to be replaced. Gas Monster produced a quotation the same day, discussed it with me and explained each element and why it was needed (not a straightforward job, new flue required, involving roofing contractor, also flushing out the heating system). Straightforward, efficient and courteous service. Job completed on time and as expected. Highly recommended.
review by Bill (February 2020)
We had an old-fashioned warm air heating system replaced with a brand now boiler & radiators across the house. Everything from the initial enquiry, the quotation visit and then the works themselves were carried out to the highest standard. Also really great customer service responding to emails and calls very professionally.I wouldn’t hesitate to recommend Gas Monster to others.
review by Matt F (January 2020)
Gas Monster were recommended by a friend. Don’t let their name put you off! Excellent service when installing a Nest thermostat. Very friendly, polite and helpful.
review by Rich (December 2019)
Excellent service Excellent work Excellent workmanship Thank you very much
review by Nikki P (December 2019)
Gas Monster replaced our ancient office boiler which we could no longer get parts for. The installer was courteous and efficient, turned up when he said he would and worked full days until the job was done. Attention to detail was excellent too. Thanks
review by Andy (December 2019)
Having had a new Vaillant boiler installed by British Gas a couple of months ago, I was disappointed to have a central heating failure so soon after. I was further dismayed when British Gas told me they were unable to send anyone round on their HomeCare agreement for a full week, despite us having a small child and no source of heating. I found Gas Monster, called them up and they had someone out later the same day who identified the fault, fitted a replacement heating pump and sorted out the problem within a few hours. He turned up when we were told he would, he was very polite and efficient and I’m very impressed. I’m very pleased to have found such a great company locally and when our free period of HomeCare with British Gas is expired, I shall most likely not be renewing it after their poor performance!
review by Andy (December 2019)
Excellent work and service
review by Nikki (November 2019)
I first started using Gas Monster many years ago when I was working in Cambridge and we needed someone to service the gas boiler there. At work, we were so impressed with the good service we received from Gas Monster that I decided to use them for my home. Wayne regularly serviced my gas boiler, for several years, sometimes with his apprentice, Jack.Four and a half years ago, I moved to a bungalow, which sadly had a very old gas boiler, which decided to die a week before I was due to go to Australia, in a particularly cold November. Wayne came out and gave me sound advice about which boiler I could have, just before I left, for Oz. I was more than happy for him to come in whilst I was away and fit my new combi boiler. Wayne or Stephen have regularly serviced my new boiler every since. Checking all the radiators are working well and that everything is functioning as it should do.The company have grown so much since the early days, and I’m ashamed to say, I didn’t know until reading the reviews, that Gas Monster also do bathrooms, plumbing etc. You always know that you will get a good, honest job completed, from start to finish, by a clean, courteous band of well-trained engineers. Thank you Wayne, Stephen and the rest of the gang, not forgetting Rebecca, who beavers away in the office sorting out all our accounts.With many thanks for all your help over the years.LM Cambs

Stephen came to the house in a very cheerful mood, and despite the thorny problems he encountered with our boiler, he remained cheerful and positive while fixing the problem! I have total confidence that the workmanship is of a very high standard. I also appreciate the details like putting on shoe covers while in the house, and the tidy way in which the work was carried out, including vacuuming. Thanks so much to Stephen and the team on the phone – you were all very helpful!

Will was competent,courteous and interested in listening and acting on our concerns. Thanks you.
review by Anne, Cambridge (November 2019)
Ripping out a 30-year-old bathroom and sorting out various leaks was in itself a big project. Installing new pipework, tiles, flooring, bathroom fixtures and electrics involved a number of tradespeople and a lot of planning. Everything was handled brilliantly from start to finish and we are absolutely delighted with the work done. Everything was done professionally, efficiently and on schedule. It was also nice for us to be consulted throughout the whole process so we really felt involved and valued.
review by John Oakington (October 2019)
Very pleased with work done. Boiler replacement and flue repositioned with the minimum of fuss. Also arrived on time each day.Would definitely recommend this company.
review by Mary (September 2019)
Did a great job. Arrived on time and finished in one day although Steve thought they may have to finish next day. Very proficient and thorough. Would definitely recommend to others.
review by Alan F Cottenham (September 2019)
We wanted to take part of a bedroom to make a cloakroom off the hall. I called into Gas Monster’s office and received a very friendly and positive response. The job required a number of trades and a schedule was provided well in advance. This was adhered to and and the job went very smoothly. The end result is even better than we expected and the electrician even discovered an unrelated fault in our boiler wiring and rectified it whilst on the job. I can recommend Gas Monster wholeheartedly and am so glad I discovered them.
review by Peter T (August 2019)
Gas Monster regularly service our boiler and recently fitted a new towel rail in our bathroom. As always, the crew were extremely friendly, professional and carried out the work to an excellent standard.
review by Mike (July 2019)
Replaced an old boiler and tank with a new combi boiler, would highly recommend, friendly, polite and hard working, will definitely use again.
review by karen (July 2019)
Simple boiler service. Steven was also very helpful and gave great advice that will help me explain plumbing faults to our building developer. Many thanks
review by Paul (June 2019)
New boiler in next to no time, next to no trouble, and a pleasure to do business with.
review by David (June 2019)
Gas Monster replaced our heating system. Very professional and helpful from start to finish, extremely neat job, and very tidy when working. Have also used them for boiler servicing and repair. An excellent company.
review by Anna (June 2019)
I have had a number of projects, repairs and maintenance work carried out by Gas Monster Ltd. I am very impressed with their knowledge and professionalism and would have no hesitation in recommending Wayne and his team.
review by Rob Corder (June 2019)
Great experience and the online booking system makes it a breeze. Thank you.
review by Al (June 2019)
We had a new boiler and hot water cylinder installed and the central heating system flushed out and serviced, plus some gas pipe renovation. We are very pleased with the result, and with the standard of workmanship. Will and his two apprentices Reis and Callum were very pleasant and professional, and minimized disruption. they left everything clean and tidy. Highly recommended.
review by Robert and Isabelle, Cambridge (April 2019)
Steven travelled from Cambridge to North Norfolk to repair my Uponor under floor heating system.Arrived on time did a great job
review by Suffield John 2019 (April 2019)
The quote came through quickly and booking the work in was done to suit us. We also had another problem with our heating that no engineer had successfully diagnosed. Stephen diagnosed it within half an hour and it was duly fixed. Stephen and Reiss worked well together. They arrived on time each morning and worked as cleanly as is possible with plumbing. They put down protective coverings each day and cleared up each evening. We will definitely recommend Gas Monster to other people and these two engineers in particular. It may be a small matter but I think corporate clothing just looks professional.
review by Petra (March 2019)
Highly recommend Gas Monster. Scheduled to arrive between 14:00 and 15:00. There at 14:00. Friendly and tidy. Would definitely use them again.
review by Tim (March 2019)
The Gas Monster team have been brilliant – from the initial diagnosis of the problems caused by our ageing boiler(s) to the installation and revitalisation of our hot water and central heating systems. The work has been carried out promptly, efficiently, cheerfully and thoughtfully. Many thanks to all involved.
review by Ralph (March 2019)
Wonderful job. Efficient and very polite. Thank you!
review by Juliana G (Cambridge) (March 2019)
Steven is a brilliant engineer who understood our heating system which has flummoxed countless engineers in the past. He was courteous, thorough, explained what he found / proposed and got the job done, including simplifying the system for easier maintenance and staying to do a gas inspection and issue a certificate so we are reassured everything is satisfactory.Would not hesitate to recommend to anyone with a tricky heating problem.Wayne gave us sound advice before Steven came. 5 stars all round Thanks
review by Lesley G Essex (February 2019)
As always,Thank you for you help and support. Very much appreciated.
review by Nikki (February 2019)
We are delighted with the service provided by gas monster. We now have a wonderful fully working shower thanks to Harry & Reiss and Brian did a wonderful job of tiling. Thank you very much guys for getting it done so quickly and efficiently!
review by Ed williams (January 2019)
Brian did a fine job installing my Megaflo Eco hot water cylinder, as well as building the very neat wooden box on which it stands.I have to say how impressed I was with how efficiently he positioned the outlet pipe. He found a gap between the kitchen cupboard and the outside wall, so I lost not cupboard space whatsoever, and the exit hole through the outside wall was positioned low down near the plinth behind the freezer which could fit very neatly back into its space without any interference with the opening of my cutlery drawer. The hole was neatly filled in – so no danger of insects entering the kitchen there! Everything was left all neat and tidy after the jobs were done. Thank you.
review by Di (January 2019)
Prompt and very efficient, getting new parts and installing on an Uponor underfloor heating system. House is now warm and heating system reliable. Thank you Wayne and Steve
(January 2019)
Having coaxed our old boiler through several winters, we finally bit the bullet when our boiler was finally condemned and not working.We got a couple of quotes, read the reviews for Gas Monsters services , and in addition knowing Wayne and Gas Monster were a Which Magazine Trusted Trader, we opted to use Wayne’s services.We were not disappointed. Clear, trustworthy advice and expertise. Ability to discuss fully what would be best for our needs. Excellent workmanship – the pipes are a work of art and give us pleasure when ever we see them!. Clean, prompt and all his employees a pleasure to have in the house. In this day and age and being some what cynical, we felt very ‘safe ‘ with Gas Monster….. would have no hesitation in recommending them . Rebecca and Andrew Wilkinson
review by BeccaWilk (January 2019)
I have used Gas Monster before to replace a boiler and shower, and more recently to refurbish a bathroom. I was extremely pleased with the results and my thanks for a job well done. Wayne gave good quality advice for the job initially and the team carried out the work very proficiently. They were clean and tidy in their work and also polite and cheerful. I found receiving a work schedule at the start of the job to be really helpful so that I knew who would be working each day and when. A very efficient and competent team and I would highly recommend the company.
review by Janyce D (January 2019) (January 2019)
Brian arrived promptly at 8am and stayed with the job until it was finished after 6pm making sure all was well before leaving.Our heating has never been better.
review by Jonathan (December 2018)
Steven was polite, courteous and punctual. We are very pleased with his work installing a Matrix upgrade. Thank you!
review by J (December 2018)
Wayne has been fixing a bad boiler I’ve had for years. He always turns up on time, is helpful, patient and courteous and gives very knowledgeable advice. Wayne has helped me out of some real scrapes when the boiler died and needed resuscitating quickly.I have now replaced the Vaillant with a Worcester Bosch, on Wayne’s advice. I got several otehr quotes – none were significantly cheaper, and its clear not the same quality of advice or likely the job itself.I’m extremely happy with the job the Boiler engineer Will did with his apprentice Callum’s assistance. The Job was completed on time so we had heating over the weekend. Any minor issues were sorted out on Monday. The pipework looks very neat and tidy. Will explained everything he had done and showed me how to use the controls. They were a pleasure to have around in the house and were extremely clean and tidy at all times. Look no further – Get Wayne and Gas Monster to do the job !
review by Jim (December 2018)
We couldn’t be happier with our new boiler installation. From the outset we were impressed with the thorough and professional survey carried out by Wayne who helped come up with clever solutions to an installation in a tricky space in a small cloakroom. Other companies did not show the same care and can-do attitude. In terms of the installation Brian did a brilliant professional job hiding as much of the pipework away as possible, and doing an incredibly neat plumbing job. He was clean, tidy and a real craftsman, cleverly solving challenges associated with the new boiler location as they came up, and communicated very clearly with us throughout. The whole installation is clearly of a very high standard with no corners cut, right down to making good where the old boiler was sited, which exceeded our expectations. We would thoroughly recommend Brian, Wayne and the team at Monster, and would not hesitate to use them again. We love our new Bosch boiler and the whole room has been transformed with the new boiler location.
review by Jonathan (November 2018)
We have just had a new boiler fitted by Gas Monster, this was done at the same time as we are having an extension built and Brian had to deal with this all going on around him at the same time along with a change of plan for pipe routing, this was all done without any fuss and the work was completed ahead of time. Brian was clean, tidy and courteous at all time. Would recommend to anyone.
review by Neil (October 2018)
We have used gas monster several times for gas safety servicing and fitting new boilers into our rental properties. They are always polite, punctual and go out of their way to ensure our tenants are looked after to the highest standards. Thank you for all that you do it’s much appreciate. Regards Ho
review by Jo (October 2018)
We have a lovely new bathroom! Harry & Reiss were polite at at all times. Modifications and mind changes from the initial plan were well coped with. Happy to recommend the Gas Monster to anyone thinking of a bathroom project.
review by Conrad & Rowan (October 2018)
It was a pleasure to have Will working on my property. A series of complicated jobs was done with consideration and care. Couldn’t be more pleased with the attention to detail and professionalism he showed. I strongly recommend this company. Ernest Dalton

We have used Gas Monster several times for boiler servicing and minor plumbing jobs. This time they provided and installed a new boiler and heated towel rail. We were happy to go away for a few days and leave them to get on with it. All done when we got back and all left perfectly clean & tidy and working perfectly,highly recommended.
review by Mike (October 2018)
We changed a gas boiler for an electric one. Everything was done in a very professional and efficient way. We were very satisfied and would not hesitate to use them again or recommend them to anyone else.
review by Brenda and Niels (September 2018)
I had an old boiler and tank removed, and a new combi boiler installed. The whole operation was efficiently carried out, from Wayne discussing the options with me, and emailing a quote the same day, to the installers arriving when they said they would and leaving the work area clean and tidy every evening. A very pleasant company to deal with, and I would use them again. Absolutely no complaints about anything, and I will get them to do the annual services.
review by Andrew (July 2018)
Prompt diagnosis of fault in gas boiler.Excellent workmanship.Courteous professional teamI was grateful for the engineer’s willingness to take note of my tight time schedule and let me know when he was stuck in traffic.I was also impressed that, although my boiler was installed 18 years ago, the engineer acknowledged that it was a good make “back in the day” and did not try topressure me into a replacement.I highly recommend this firm.Jane M.

Really friendly and professional team. We were very impressed with how they coordinated all the people who were involved in completing the work. Highly recommended!
review by Hazel and Michael (July 2018)
Water cylinder and underfloor heating problems sorted out quickly and efficiently. Engineers were so nice and the work done to the highest standard of workmanship. Professional, efficient and the tidiest workmen I have ever had in my home.Can not recommend the company enough.

Bathroom refit.
Great professionalism and high workmanship from Wayne, Will and the team. The bathroom looks amazing and works a treat. They left the place immaculately clean at the end of the project.
Thank you Gas Monster.
review by Johnny (March 2018)
Fitting new radiators to downstairs. Will and Harry did a great job, very tidy. When one radiator was defective Wayne and Melinda came out a couple of days later and fitted the new one. Highly recommended.
review by Clive (March 2018)
We’d had a problem with our main boiler for over 3 months and which a service contract with a major national had failed to resolve. Then our underfloor heating packed up. GAS MONSTER resolved both in one hour with great curtesy and left me with some tips should I need to call the unmentionables out again. First class.
review by G.P. (Sir) (March 2018)
We needed a new gas boiler and the whole system sorting out to make it run properly.From getting a quote to Brian and Co. arriving punctually each day everything ran smoothly and efficiently.Everything was left neat and tidy at the end of each day and I would highly recommend Gas Monster for similar work.
review by Neville B(March 2018) (March 2018)
The guys from Gas Monster did a boiler install for us following the construction of our new extension. The house had always been a bit cold with the previous boiler and we had lots of cold draughts. I’d done quite a lot of the central heating pipework myself, and the engineers worked with me to design the boiler spec and location, then did a great job of the install. Everything is now up and running and this is definitely the warmest winter we’ve had in this house. Great work.
review by Jack H (February 2018)
Excellent service. Polite and friendly and explain exactly what they needed to do.
review by Richard J (February 2018)
When the engineer did our boiler’s service last November he found a major job was needed. The team carried out the work in January with excellent efficiency. I am happy to recommend Gas Monster to anyone looking for gas equipment maintenance.

Very good for everything. Could not ask for better. Very professional and very tidy.

Will and Melinda were excellent replacing our boiler and carrying out a Power Flush. Both are a credit to the company. It is a pleasure to be able to put business to local companies that helps the local economy
review by Phil A (November 2017)
Brian and co arrived spot on time and completed a system power flush very efficiently even showing us the thermal images of rads showing no cold spots.
review by (November 2017)
Steven has just finished sealing our central heating system which also involved a very thorough flush of the system. He was a real joy to have in the house and did a great job. He was always on time and even popped back to fix a small fault (not caused by him) to ensure that the job was 100% perfect.
Strongly recommended.
review by Terry (October 2017)
Gas Monster whole team effort, to totally refit my bathroom…they have put up with all my fussing and changed things accordingly.Will has done a beautiful job and they even have a girl plumber, who tidies up and does the washing up!!! Bathroom looks amazing…well done Gas Monster
review by Carol (October 2017)
We were pleasantly surprised at the work we had undertaken. The house was left selflessly tidy. The work undertaken is of a high standard you would hardly know that the work has been undertaken . I would highly recommend this company for work you need to undertake.

Bathroom refit
The whole team were brilliant from coming to give a quote, right through to the finish. They are all friendly, hard working and very patient with us while we decided what we wanted done and if we changed our minds. I would highly recommend them to anyone. They were a pleasure to have in my home and they treated it with respect too. Thank you Gas Monster. We have a fantastic bathroom that we are really pleased with.

Full bathroom and utility room refit
Great service and team. Recommended by a friend, Wayne and the team were brilliant. Very patient with us whilst we decided what to do and they arranged everything from walls being knocked down, tiling, plumbing, plastering and all the other odd jobs that needed doing. Work was done promptly, professionally by a friendly team. Encountered no problems when we asked for a few units to be changed. No hidden costs or corners cut. It’s transformed our horrible old bathroom and utility area! We would definitely use them again and will be recommending to friends.

Put in a new stop tap (old one was stuck solid)
Pleased with work done, as usual. The problem was thoroughly assessed with a reasonable quote and the job itself was carried out efficiently. Always punctual, polite and friendly. Thank you! One suggestion: in your logo make it clearer that you do plumbing work. I hadn’t noticed this over the 4~5 years we’ve had our boiler and gas appliances serviced! Perhaps something like; “GAS MONSTER – plumbing work also.”

Gas Safe certification and boiler service
These guys are not only super-efficient and respond really quickly, when they come out they are tidy, respectful and friendly. Not a single sharp intake of breath or unpleasant surprise. The also use the latest tech to send out your bill. Can’t recommend them highly enough.
