Yearly boiler service found our boiler needed several replacement parts. Gmh engineers went over and above, throughout the day to pick up the new boiler parts to insure by the end of the day we had hot water and fully functioning boiler. Thanks Gary and Harry as usual great service.

Gary Horton had serviced my back boiler for several years and I was impressed by his attention to detail and knowledge. I therefore had no hesitation in asking him for a quote to remove the old boiler and have a condensing boiler installed in the new position in the Garage. The work also involved replacing an old radiator in the Kitchen and also putting in an extra one in the Lounge. The system was power flushed and left running with an inhibitor. The team arrived promptly each day and worked well and efficiently. The installation went smoothly and the team was considerate and thoughtful throughout. I will be using them for the annual boiler service and I have no hesitation in recommending this company.

Used Which Trusted Traders to find a local CH company to replace a CH motorised valve with leaky connection and discovered GMH Ltd with great reviews. After exchanging a couple of emails with Mandy in the office and sending a photo of the problem, I received a competitive quote and an appointment was made for a couple of weeks later. Harry arrived promptly on the day with the parts and completed the job without faff or drama. I plan to use GMH for all future CH and plumbing work. I thoroughly recommend GMH Ltd. Which Trusted Traders is a great platform to find quality businesses.

GMH were amazing! On the days the new boiler was being installed, they arrived at the arranged time every day, minimal amount of mess and noise and fuss, very helpful information from the main engineer when installing the app, the boiler works beautifully and the installation work looks great.

GMH gave a clear and detailed quotation for installation of combi boiler to replace conventional central heating boiler. Quote was prompt and replies to a couple of queries were also very quickly responded to. Work involved removal of hot water tank/and associated pipework as well as draining of cold water tank and removal of pipes in loft. New pipework was installed to adapt central heating and hot water to new system. Gary and his team arrived promptly, worked solidly over the two days, gave clear explanation if I had any questions. A really efficient team. I have now booked them for a smaller job and will use them for annual service. I would recommend them highly.

We required a boiler update. Gary from GMH visited to assess our old boiler and gave advice on suitable products. GMH sent an email with a quote and the agreed date and time that the work would begin. The work commenced at the agreed time and date. The guys worked in a considerate and thoughtful manner. The work was completed in a timely way and upon completion, everything was tidied away. What's not to like? 10/10

After having a water leak to a mains pipe in the hall. The plumber sent by the insurance company could not stop, the leak the only advice he could give me was to "call the water supplier". I called GMH they arrived quickly were courteous, friendly and fixed the leak within the hour even helping me to clean up the mess. Would highly recommend will definitely be using them again.

I have used Gary for many years for various gas safety checks for rental properties and he's always proven to be prompt at both replying to emails and attending the property and he's extremely personable with good, friendly advice. On the last occasion, we had a bad smell in our bathroom which had been a problem for some time. Gary had a look, made a recommendation to fix it and within 3 days had the required part and had installed it! All for very reasonable pricing. We wouldn't go elsewhere for our gas or plumbing needs and would recommend Gary for anyone looking for a great, local service.

Gary Horton has been servicing my boiler for many years and I have always been more than satisfied. He and his employees are courteous and helpful, clean and tidy and totally reliable. They are pleasant and friendly and highly professional both on the phone and in the house. This recent job was not urgent but very annoying as the heating system was very noisy due to air in the pipes. It is now quieter than it has ever been and I am very pleased. Gary was very cooperative about the social distancing and is happy to discuss these situations alongside the work needed. I have previously recommended him to another family member who is also extremely satisfied with his work. I have no hesitation in rated him highly.

We've used GMH for many years and know lots of people who use the company locally. Had new boiler fitted 3 years ago by them and had services each year since. Workmanship is excellent. They are well organised and all the guys in the small team are just brilliant to deal with, always offering solutions and advice. Tidy workers too, taking care to make sure you're 100% happy on every call. A really motivated group of technicians with a good office organisation behind them. Really recommend this company.
