Annual Service of GCH Boiler
Gianne returned to do another annual service. His imminent arrival was announced via a message saying he was on his way with a link to a map showing his progress. As always, he was polite, informed me of all work he was doing, and kept me updated on his progress. He left the work area spotless. I would have no hesitation in recommending his service to anyone.Verified reviewerJob location: HG4RDavey B10 Gas Boiler Servicing / Repair

Hi, this is GM Heating Ltd, and my name is Gianne Merriman,
To give you some idea of my background, in summary, I undertook a 4 year apprenticeship in Leeds, with a local heating company.
Shortly after qualifying, I worked for a commercial heating company for a further 3 years, gaining invaluable hands-on experience around the UK tackling a diverse array of complex heating projects.
Ultimately, armed with this experience and skill I founded my own heating business, GM Heating, which now undertakes local, reliable quality work throughout the whole of Yorkshire.
My company prides itself with exceptional customer service, value for money work and reliability, demonstrated by the number of positive customer reviews on both Checkatrade and Google.
Whether you need a new boiler installation, routine servicing, or repairs, our company is here to offer local, reliable expertise to deliver personalised solutions just for you.
At GM Heating we deliver guaranteed quality work, with a very personal touch.
