Really impressed with GLM. Suppled and fitted a new boiler and designer radiators all down stairs which are gorgeous. Removed the old tank with zero mess left behind. Really impressed with the time scale of things, great communication and really fair price. Gary went the extra mile and sorted some gas pipes out in my kitchen Reno and is coming back to fit my new hob which wasn’t part of the price so thank you very much Gary. I will definitely recommend GLM. Thank you

Needed a Plumber in an emergency as the boiler had broken down leaving my Uncle without heating and hot water. Spoke to Gary and he said he would be able to call later that day to look at the job and do us a quote. We decided to go ahead having a Worcester Bosch Combi Boiler. Gary and Aidan are really professional super hardworking and have done a brilliant job. It’s nice to be able to recommend a company that is local to us who really care about their customers. First class!

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!

First class company and a top quality job

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.

My boiler overheated a few days before Christmas and it wasn't under warranty with the manufacturer,I called Gary at glm and told him what had happened. Lucky he was able to call the next morning to have a look and arranged to come the following day to replace my boiler. All the work was carried out to a exceptionally high standard all the mess was cleared up and it was done in a few hours ,can't thank and recommend glm enough

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.

Removed old boiler system and replaced with a combi boiler. Needed the work doing at short notice - he said he'd try to achieve it by the date and was true to his word. Polite, good communication and excellent pipe work.

I would highly recommend GLM heating and plumbing, from quoting to replacing our old boiler. Gary and his apprentice were polite and friendly but very professional. The kept their mess to a minimum and tidied up when the job was finished. Gary explained how the boiler controller worked and helped set it up. Excellent job done couldn’t fault anything and would highly recommend.

GLM replaced our existing boiler for a new Worcester model. The whole process was excellent, from selecting the correct model, quoting, installation, and follow up aftercare. Gary and Aiden are reliable, genuine hard-workers, they worked the installation around our schedule to minimise the impact to us, and the end product is excellent. I would highly recommend GLM services.
