    GMH can be trusted to do good job

    Posted 02 April

    I am pleased I chose GMH to install a new boiler in my home. They were professional, honest and tidy. Their quote was detailed and included all the necessary stages to ensure they did a quality job. A Which BestBuy boiler, a scale reducer, de-slugging, flushing the radiators, building control and guarantee certificates. All of which they delivered. Thank you GMH.

    Plumbing and heating at it's best

    Posted 19 November 2025

    I've use GMH Ltd for a few years now. They were originally recommended to us by a family member so when we needed a new combination boiler I thought we would try them out. Recently we have moved into a very old house which needed a complete overhaul of the water tanks as the house had no water pressure. With both jobs GMH were fantastic and the end result was faultless. The guys who did the fitting were friendly, knowledgeable and took time in explaining the process of the work. I would certainly recommend GMH LTD for any plumbing and heating work.

    Excellent Work carried out to Time and Budget

    Posted 12 November 2025

    I have no hesitation in recommending GMH. I had a new boiler and two new radiators fitted. GMH also updated 30+ year old pipework and cleaned 'flushed through' the existing CH system. The work was carried out within time and budget. Having been given accurate start and (likely) finish dates via a dedicated office, the friendly team arrived when they said they would, stayed on site throughout the process and on the final day did not leave until everything was working to my total satisfaction. The house was left spotlessly clean. I am delighted with the outcome and aftercare service.

    Gas Fire Servicing

    Posted 03 October 2025

    Gary from GMH Ltd came yesterday to service my gas fire. He did a brilliant job and even got the ignition working again. I would highly recommend him and his company.

    Great service and communication.

    Posted 23 July 2025

    Excellent service - came to give a quotation the same day that I made an enquiry and scheduled the work within a week of the visit. The team from GMH arrived when they said they would and completed the work on time, keeping me appraised on progress. Great communication and great work. If I had a (very minor) complaint it would be that the team did not do a thorough job of cleaning up afterwards, but not a big deal. Very happy with the work.

    New Fan

    Posted 18 April 2025

    The experience was fantastic as always. Fitted quickly and professionally, price was good. The engineers were punctual and helpful as always. The receptionist and booker Mandy fitted us at our mutual convenience as she we had no heating or hot water. We also spoke to Gary the owner and he was charming and understood what we needed done. Thanks to you all
