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.

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.

Gary responded quickly to my initial enquiry and was able to pop round to quote for the work required. We wanted to get rid of our old boiler and tank, and replace with a combi system. Gary provided a few options suitable and quoted for all options that same day. We booked Gary in for his next available time which was a couple of weeks later. Gary and Aiden were prompt, efficient, very reasonable with pricing and extremely tidy. Gary kept us up to date as the job went on and took time to give us a tutorial following completion of the install. Other gas engineers wanted to charge us for moving the boiler to the loft and provide a new hive. Gary did none of this. He was able to put the new boiler where we wanted it and use our existing hive. Thanks again!

GLM gave a very competitive quote for a top quality Worcester boiler. They were flexible with the fitting date to suit us and also really helpful in siting the boiler to make best use of the space we had available. Both fitters were polite, friendly and obviously experts in their field. After many years of having to chase gas fitters for appointments, this firm turned up when they said they would, carried out the work agreed and charged exactly what they quoted. They also carried out some additional work which materialised once the fitting got under way but never charged an additional premium for this. Give them a call, you won’t regret it.

Gary contacted me promptly and professionally within 24 hours of me submitting my first enquiry directly to Worcester. He explained that he could not visit immediately but after I sent him photos he prepared a competitive quote and suggested that because my existing boiler had completely failed, he could replace it within 48 hours. I sought other quotes but Gary seemed on the ball, friendly and professional so I went ahead. He and his colleague visited on the day agreed (and bang on the start time agreed) and the new boiler was installed in place of the old one by the end of the day. Both Gary and his colleague were hard working, clean and tidy and came up with various fitting solutions for vents and drains which were a great improvement over my last boiler. I have no hesitation in giving GLM a five star reference and look forward to offering even more tea when they visit at service time !! :)

Replacement of Worcester Bosch Boiler
Having recently moved to North Wales and having problems with the existing boiler, I looked on the internet for a Worcester Accredited Installer and found GLM Boilers & Plumbers - what a great find! I phoned them and Gary and his assistant installed a new Worcester Bosch boiler in a different position, which wasn’t an easy task. Gary is very professional both with his work and communication. Nothing is too much trouble for him. Gary and his assistant worked as a great team and removed old boiler etc. and left the place very clean. They are very polite and considerate and I highly recommend them.

Anyone considering a boiler replacement could not do better than using GLM Gas and Plumbing. Gary is a great lad with a very high level of competence, a very diligent worker and extremely efficient and helpful. The completed job for a new Worcester Combi boiler was superb. All pipework very neat and tidy and the installation looks brilliant and works like a dream. Everything left in a tidy state and all completed with minimum fuss. Gary is assisted by his apprentice Aiden who too is an excellent worker. All in all I cannot recommend him more highly. The price was very competitive and with hassle free no interest finance available its a no brainier. A new boiler installation is a big decision so choosing the right installer is vital. Anyone choosing Gary's firm will not regret it. without question, I be using him for maintenance on the boiler in the future.

Firstly the contact we had with Gary when getting a quote was great, very fast replies and he also took into account our needs and requests without any hesitation. We had our old conventional boiler system removed and a new Worcester fitted in it’s place. The old boiler was removed from the kitchen and the new one fitted upstairs in the airing cupboard. Gary and Aiden are both extremely professional and kept the house tidy throughout the job. The work was completed on time and to a very high standard. Couldn’t fault anything about them at all and would highly recommend to anyone. We will definitely be using them again in the future.

I chose GLM gas and plumbing to install a new boiler and replace radiators. From start to finish of the job, I couldn't fault their approach to the job. All very professional.

We were looking for someone to service our boiler after our long standing engineer said he could not do it this year. Saw Gary’s van in driveway on our road and started talking to him. He was very approachable and helpful. Within a few of minutes we had a service date sorted and booked into his diary. (The back of Gary’s van was very organised and tidy which, to us, says a lot about how a person works.) Gary arrived on time and quickly carried out the service. We would definitely book him for the next boiler service and, should the need arise, any other heating and plumbing work.

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.

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.

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.

I contacted Gary to replace and move my existing boiler from the middle of the house to the utility room. His workmanship was very professional and the pipework was neat and tidy. He removed the old flue and sorted the roof out. All of the rubbish was removed, and the house left clean and tidy, definitely recommended.

After my old boiler decided to give up, I looked for someone to help and Gary came with great reviews. Which he didn't fail to live up to! I liked the fact you could use whatsapp to message him, I found it convenient. I had a feeling my boiler was old, but didn't have much information on it, as it was already here when I moved in. Gary came to the rescue! the whole process was easy and straight forward. He came to look and explained everything to me, I could of fixed the issue at hand, but as i'd already thought there was no point with it being so old. So Gary went through options of new boilers and the best one for me. He was down to earth, polite, friendly, dressed smart, punctual, explained it all to me really easily and kept me up to date as well. He was realistic with times of when he could come, with other jobs he had on as well. So I went ahead and had a new boiler installed and I can't fault him on how hard working, efficient, and diligent he was. Gary and his apprentice came on time, were respectful, professional and kept me informed. As the property was renovated and someone had built the cupboard around the boiler, he had a bit of a challenge to get the old one out, which he achieved with no issues caused to the cupboard. Once finished he tidied up after himself and explained how it all worked and how to use the easycontrol app. Honestly my home has never felt so warm, even when the old one worked! Everyone needs Gary for their boilers and heating, he's the best!!

We contacted Gary after using the internet to search for a Worcester Bosch recommended company. He had great reviews and was easily contactable, we used his facebook page. We had a problem with our Greenstar 35 CDI boiler, Gary arrived at the arranged time and was very thorough in checking the boiler, he then had to order the required parts, he kept in touch with us to let us know when they arrived and made arrangements to come back to fit them. His service is exceptional, he was professional and yet friendly at all times and we were very happy with the final outcome including the cost. We have no hesitation in recommending him and will definitely use him again.

GLM fitted a new Worcester Bosch Gas boiler. Gary turned up on time was smartly dressed and very pleasant and helpful. The job was carried out and completed on time and in a very professional manner. Gary also explained how to work the control system on the IPhone. We had a couple of queries after installation and Gary came back promptly with the explanation. Gary also tidied up after completing the work and left the work area spick and span The final invoice matched the amount quoted. We would have no hesitation in recommending Gary to other potential customers.

After years of being a British Gas customer and paying a service agreement every year, I thought I would have a change, reduce my bill substantially, and give someone local the work. Gary agreed to come and do my boiler service, and the date fitted in with my requirements, he expected to be with me at about 11:00, and it was. He was very thorough and explained what he had done, in a professional and friendly way. I was very impressed with the service and would, and will be, recommending Gary to everyone I know.

Gary has just completed the installation of some new radiators & valves as part of some building work in my house. He even helped to resolve a separate issue we had with our cistern. It's refreshing to be able to work with a tradesman who clearly takes pride in his work, is professional, polite and his pricing was reasonable which is always a bonus! Don't hesitate in choosing Gary for any plumbing work that you need, you won't regret it.

Gary fitted a replacement gas boiler for us and the whole process from quote to commissioning was great. For the quote, he turned up at the agreed time and texted before he arrived. The meeting was quick but thorough and covered every aspect of what we wanted doing. There was no pressure at all and he listened to what we wanted, made suggestions and came back with a written quote within the agreed time. We accepted the quotation and he came back to us with a date. He explained how long the replacement would take and what time he would arrive. The installation was carried out efficiently, tidily and to a really good standard. Most of the work was done on the first day and the second day was commissioning, making good walls (who knew a plumber could plaster so well) and then giving us training on how the system works and what we needed to do. He passed over all the paperwork and organised the building certificates with GasSafe and the guarantee from the manufacturer as well. He was also available via text when there was a glitch with the controls (that were installed by someone else) and though he did not need to in the end, offered to come out. All told I cannot recommend Gary highly enough. He is not only a very competent plumber/heating engineer but he also turns up when he says, is a great communicator and a genuinely nice guy. Price was pretty good as well!

Contacted Gary regarding a new boiler installation. Responded quickly and came to view the job the following day. Advised us as to suitable boiler and sent us his quote that evening. Gary and his apprentice arrived punctually on both days. Fitted new boiler, condensate pipe, and replacement flue with minimal disruption. Everywhere was left clean and tidy. Would definitely recommend to others.
