The work was done efficiently and within reasonable time. The workmen were freindly, considerate and tidy. The boiler now works well and I'm sure it benefit is in terms of energy costs.instal!action was not without difficulty because of its site in a bedroom and in a cupboard with restricted space. We trusted the advice that our old boiler which we inherited would become increasingly costly to maintain and was pretty well obsolete Thank you very much for your service and we look forward to your serve in the future.

From visiting to assess the job, providing a quote, discussing and accommodating changes, through to implementing the work, communicating about and managing challenges, and keeping the house clean and tidy, Gas Monster delivered at all stages. We have used them to repair a boiler, service boilers, and carry out a heating system replacement. We have always received friendly but high quality customer care and advice alongside professional work. Most recently work done to replace our heating system was extremely neat and tidy and we are extremely happy with the work.

New boiler installed to replace an old one. Very prompt at coming to give a quote and provided good advice - quick to get back with a date for the installation. All work completed quickly and to plan. They were very respectful in the way they worked and took care and tidied up afterwards. Communication was excellent and I would definitely recommend/use again.

I chose Gas Monsters Ltd from this website and I wasn't disappointed. Wayne, the owner, was so patient with my requests and his advise was spot-on. We had to wait a a couple of months to get all the trades in place, tilers, plumbers, electricians etc - which told me the company was worth waiting for. All the trades were professional, talented in their field and polite and tidy to boot! If I had any queries I could ring or email Wayne and he'd answer quickly and with solutions to my queries. An excellent service. Will use this company again.

After returning from holiday to discover I had no hot water or heating at all, GasMonster were able to respond within 48 hours of contact and very quickly diagnosed the problem. They offered me a range of solutions, and I opted for a complete system replacement. They handled everything, including the removal of the old equipment, bringing the pipe work up to current building regulations and the installation and test of the new equipment. The new system is a massive success, and the engineers were courteous and helpful throughout the whole process. I can happily recommend their services and attest to the competency of their staff.

We have had two lots of work done by Gas Monsters. Firstly they changed all the downstairs radiators. Excellent work and good advice on the type of radiator to have. We then asked them to replace our 21 year old boiler plus sort out another problem. We got good advice on the kind of boiler to have and a senior engineer diagnosed the problem we had had for several years that no one else had diagnosed. The men work well together. They arrive on time and look professional in their corporate clothing. They lay down floor coverings and clean up after they go. Communication during the job being done was excellent so we knew what was going on. This is a good company and we have no hesitation in recommending them to people.

My old electrical hot water system, installed in an unvented store cupboard, finally died leaving me with no hot water. A number of plumbers who, once they saw the old system and its situation, disappeared without further contact. Trading Standards put me onto the local Which Trusted Traders, who gave me a list of 3 names. I phoned Gas Monsters; Rebecca answered and was most friendly and helpful, making an early appointment and warning me the work could not be carried out for a further 6 weeks because of their commitments - I knew where I stood. I think it was Brian who came to view. He saw no problem with removing my old system and suggested replacing it with a Megaflo Eco Unvented Hot water cylinder. What a relief to have a solution to my problem at last! Installation started on 2nd Jan and took three days. A decorator was scheduled for Monday 7th Jan to paint the plinth and on Fri 11th Jan an electrician signed off the installation. The old, very rusty system was taken away a few days later. All work was completed with minimum fuss - any resultant mess was continuously and quickly cleaned up. The workmen worked efficiently. I was worried that I would lose cupboard space in my tiny kitchen when they ran the pressure pipe from the storeroom to the outside wall but, no, it was positioned between the cupboard end and the bedroom wall to reach the outside wall. Again, professional clean work was completed efficiently. I happily recommend Gas Monsters.

Bathroom refurbishment

I used Gas Monster previously to replace a boiler and shower, and had no qualms about using them this time to refurbish my bathroom. An existing basin was removed and a replacement basin with unit was installed in a new position; a custom built airing cupboard in matching style was fabricated and installed; led downlights were fitted and also a dimmer switch and the room was decorated throughout. I was extremely pleased with the results. Also I was appreciative of the good-quality advice offered by Wayne initially, and the team carried out the work proficiently. They were clean and tidy in their work, polite and cheerful. Also I found the copy of the work schedule supplied really useful for knowing who would be working each day and when. An efficient team and I would highly recommend the company.

Gas monster replaced a leaking expansion vessel in my airing cupboard. They were prompt, efficient, clean and I recommend them for plumbing. Gas monster also did my annual boiler service in the summer of 2018 and I will call them again.
