Can highly recommend GLM. The work to replace my boiler was done to a very high standard, they were very efficient and the work was excellent. They took time to explain the controls and made sure I was confident in using the heating but also assured me I could contact them anytime. A great company and great guys.

New Worcester Bosch Boiler Installation

Gary and Aiden, have just updated our boiler to a new Worcester Bosch. They arrived at the time they specified, completed the work in the day in a very professional and clean manner leaving no mess. Gary explained the system very comprehensively and clearly (to two Luddites!). The guys are friendly and comfortable to talk to and give a real sense of knowing what they are doing. We would highly recommend them to anyone needing a new boiler - or other gas work.

The great reviews I have seen on the internet about this company checked out 100%. I was very happy with the standard of work to install my new boiler. Gary and his collegue Aiden got on with the job with no fuss, bother or excess noise. A radiator was moved where I wanted it, which prevented excess exterior pipework . They were very patient with me when explaining the new thermostat/ controller. Great job all around and I hope they’re around to assist with servicing and repairs in the future.

Gary and Adrian replaced our old boiler with a new combi-boiler. They were very busy but managed to fit us in. They were very friendly and polite, updated us on what they were doing and how long it was likely to take, and gave us guidance on how to set up and use the new thermostat. They did a really good job and took great care to make sure everything was done to a high standard. We were really pleased with the service and would definitely use this company again.

I had a new boiler fitted in a more accessible position and the old boiler removed. The work was completed in just over a day and the house was left clean and tidy when they finished. Gary and his co-worker were extremely friendly, polite and helpful. I would definitely use Gary again and I would have no hesitation in recommending his service. Thank you for an excellent service from start to finish!

New heating system.
A new boiler was installed with the old system requiring removal and disposal. All work was completed over a couple of days with minimal disruption and the house was left clean and tidy. My wife and I are very pleased with the work done and the price quoted/paid. Gary and his co-worker were very polite and friendly. We would highly recommend this company should anyone in the area need heating and plumbing work in their homes.
