GLM fitted our new boiler and radiators whilst we were away on holiday. Gary is very polite, helpful and totally trustworthy; they did a fantastic job. We came home to a perfectly clean house. Would highly recommend for reliability and great price. Really pleased with the work they did. Thank you

Fantastic service from Gary. Fitted new boiler, a replacement radiator and 6 thermostats, all for a great price. Arrived on time, kept to schedule, cleaned up and respected my home. Friendly and knowledgeable and put me at ease concerning the remote operation from my mobile which I was anxious about ( not being tech savvy) A mention also to his apprentice, a lovely polite young man who sorted out the issues on my mobile. Personal recommendation by work colleague and now very happy to recommend myself. Thank you Gary and your team.

GLM provided an awesome service from first contact to completion of the job. Extremely polite, professional and helpful team. The workmanship was outstanding and so was the attention to detail. They left our home spotless every day. Even addressed an additional request to put in some shelves in the boiler cupboard. Can’t recommend them enough, so very glad that we chose them for such a key job.

New Combi Boiler Installation at Short Notice
Customer Service

What can I say but excellent on all counts! Being a retired professional engineer having someone meet your standards both in quality of workmanship, knowledge, communication and ability and willingness to listen is all you can ask for. Gary and Adam? have ticked all those boxes for me. The work involved not just the installation of a new combi boiler but also modification to the basic heating plumbing with the removal of old zone valve, redundant bypass and old filter. All associated controls rewiring also done. The place was left clean and tidy, all materials, packaging and old boiler and flu removed. The price quoted was the price invoiced except for the addition of a new smart thermostat which was found to be needed. Without a doubt we will be using Gary again for all our future plumbing needs.

Gary came out to do a gas safety certificate for us, he was excellent at fitting us in short notice. He was prompt and very friendly. During our gas safety check Gary noticed that we had major gas leak. He was very calm and reassuring and incredibly knowledgeable. He stopped me from panicking and helped to get the gas board out to resolve the gas leak. Gary even came back the next day to finish off the gas safety certificate for us. Without him we could have been in major difficulties. His service was incredible. Very clean and tidy as well as professional. His communication is brilliant. I would absolutely recommend GLM to anyone and will be using his services again for all our boiler/gas needs.

Can’t rate Gary highly enough. He arrived at the agreed time and clearly explained the options, pricing and his recommendations. He replaced a 30 year old freestanding boiler with a new combi-boiler, his work was of a very high standard and he took time after the install to explain in detail how the system works. He and Adam were very professional and helpful, I’m delighted with the new boiler and would definitely recommend them for other work. Thanks Gary!

Gary installed my boiler 12 months ago and returned today to carry its first service. Again, punctual, professional and polite. I wouldn’t hesitate to recommend him. Thanks again for a thorough service inspection.

Contacted Gary to arrange a service for my Worcester Bosch boiler. Arrived promptly and completed the service finding two faults which needed attention. Excellent service and will use again.
