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.

Had my underfloor heating system updated with wireless thermostats and a central control. The engineer arrived on time, worked with minimal fuss and cleaned up after him. Also gave me an overview of how to operate the new thermostats and control panel. Great customer service from him and the office, agreeing a work date and time of arrival.

Worcester CDi 34 Install

rk? I had a new Worcester Bosch Greenstar CDI 34 installed with new gas pipes from meter. This also included 2 radiators. I had wanted 10 radiators but Gas Monster are a Premium company (like British Gas) and was outside my budget. As a premium company the actual job was handled very professionally. It starts with a survey by Wayne who is very knowledgeable and understood my requirements. The quote received is broken down by parts and labour, and all the parts listed were roughly what I could buy so it was sensible. Labour is expensive. When the work commences Wayne is back on site to talk it through with the installer. While talking through the pipe runs we could see that 2 extra radiators could be fitted for very little extra time. The fact that this was done made the whole experience worthwhile. The end result is that I am very happy I went with Gas Monster and I would use them again.
