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.

GMH responded promptly to a boiler breakdown in my 95 year old Mother's house. They were alerted early in the morning and the heating was back on by mid afternoon. The service was personal, responsive and efficient. I cannot praise them enough. We have had a 8 years of regular boiler servicing before this. I would recommend this company to everyone.

We’ve used GMH for our annual boiler service for a few years now, always very reliable with quality work and reasonable pricing. More recently Gary’s team completed some plumbing repairs for us, they have done a great job and have been very good in coming back to make some necessary adjustments. Recommended to us and would also highly recommend them.

Problem with radiators not warming up. Gary from GMH quoted for the repair, attended, fixed with replacement valve, replaced thermostat at our additional request, and completed job within 24 hours of our call. Neatly done, everything left clean (shoes left at front door too!), job completed to quoted price. Will be first to call next time there's a problem.

In the context of a planned kitchen refurbishment GMH were asked about simplifying rerouting, removing poorly sighted and unsightly pipework. In consequence of this a report was produced that was key to British Gas remediating substandard work and removing their redundant pipework. GMH did a great job on tidying the other pipes. They were asked to fit 3 new radiators plus, some upgrading and maintenance of the central heating system. Encouraged by their work GMH were also asked to install a new high level WC cistern and toilet which needed to be adapted to suit existing plumbing and other constraints. This was also completed very satisfactorily. The work was undertaken within the figures quoted.

GMH replaced our 50 year old gas boiler, and all radiator valves. The quote was roughly in line with other quotes. They turned up on time and completed the work efficiently with minimal disruption. Communication with the company was good. Gary explained clearly what was going on and was happy to talk through options. The work was done on time and to budget. I can't comment on after sales or servicing as the installation was recent. Would recommend.

I have used GMH many times over the past twenty years or so and have recommended them to family, friends and clients. They’ve just completed the first phase of works at my office, on time and to complete satisfaction. They stayed late to get the job done. Great company and strongly recommended.

New Boiler

I was recommended to use GMH by a friend who had used them to replace their boiler. GMH supplied & installed my new boiler and upgraded my central heating system with a new wireless one and installed thermostats on a number of radiators. I recommended GMH to a client of mine who also used them to install a new boiler. Subsequently in December 2018 GMH returned to install a replacement boiling hot water tap. GMH's service was reliable and good value for money and they will be my first point of call in the future.

Successful bathroom conversion

Successful Bathroom Conversion I have just had my bathroom changed so that I could have a walk in shower instead of a bath. GMH Ltd were very helpful in the planning of the work providing me with brochures so that I could see what I was ordering. They also gave good advice on what would be appropriate and what would work well. When it came to the work GMH Ltd made a quick job of removing the old fittings and enabled the tile fitters to start their work as the schedule had called for. GMH Ltd also organised the electrician to replace the electrical fittings . Finally they installed the new shower unit, sink unit and toilet unit. The work of GMH was of a high standard and I am satisfied with the new bathroom. I could recommend GMH Ltd to anyone.

We have used GMH's services for approximately 10 years. In that time, GMH have totally upgraded our central heating system with a new wirelessly controlled one, installed a number of new radiators, fitted in new boilers, installed a mega flow hot water system with booster pump, a water softener, a water pressure reducer, as well as fitting in new toilets and cisterns. GMH regularly services our appliances and provide a very helpful repair service. Their expertise, advice and service has always been reliable and first class and we are so pleased to have found them. Thank you GMH.

I have had GMH service our boiler each year since they replaced our old back boiler with a Bosch boiler in a new position 12 years ago. Always happy to recommend Gary and his team and they have replaced a boiler at my daughter’s flat and service my parents’ boiler too.

This is an outstanding Company.. Gary Horton and his team put in a new boiler and all that that entailed, plus yearly servicing for approximately eight years before I moved. He is professional, knowledgeable, courteous and willing to go the extra mile to help and advise, his staff are superbly trained by him and all are highly qualified. I have recommended Gary to others and he fully deserves every accolade for the consistency of the high standard of his workmanship. I wish Gary and his Company every possible success

Recently my heating stopped working. I got GMH to call the same day. The engineer found the gas valve on the boiler had broken. He fitted a new one, tested it and got the heating working. The cost of the work was very reasonable. Any problems after work was finished was sorted out free of charge. The office staff and engineers are very helpful, pleasant and reliable. I have been using GMH for 10 years for boiler servicing every year and other problems. It is a pleasure to have GMH working for me.
