New Combi Boiler Installation at Short Notice
Customer Service
Quality

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.

Boiler replacement

Gary contacted me the day after I had filed a request for an approved installer to replace an existing broken boiler. He visited the same day and provided me with a quote later the same day. He returned two days later and installed a new boiler. The old boiler was extremely difficult to remove because it was in a fitted, bespoke kitchen. Gary was punctual, polite, and extremely efficient. He tidied up all the mess that was inevitably made getting the old boiler out. He fitted a horizontal flue and sealed off the previous vertical flue that was located in a chimney. He is by far and away from the most proficient and 'user-friendly' tradesman I have ever dealt with and I recommend him very highly.

Gary recently replaced a dead floor standing boiler, located on the third floor with the complication of a roof flue. It was a difficult job requiring taking apart the old boiler bit by bit and arranging a roofer for the new flue. Gary and his apprentice got done really quickly including fitting in the old boiler extraction on a Friday afternoon so that there was no risk of a delay for the roofer. Gary was professional from start to finish with a thorough quote discussion covering some potential issues and work completed exactly as scheduled with everything left clean and tidy. I would strongly recommend Gary for any Boiler Installation.

Called Gary at GLM to see if he could help with an urgent issue regarding a leak. Gary was fantastic, came a couple of hours after me contacting him and managed to detect the leak and fix it all on the same day. Cannot thank him enough for coming so quickly and sorting and very reasonable price. Would not hesitate to use Gary again and will highly recommend him.
