Gianne attended to carry out a routine boiler service. He was very polite, respectful and knowledgeable speaking and explained everything you needed in detail. Wasn't pushy if you dont need and upgrade hewont try and sell you one. A very competitive price especially for a thorough job he did, was around 1 hour in total from start to end.Verified reviewerJob location: LS710 Brilliant service

Gianne was great. He was professional, knowledgeable, and acted quickly when learning our boiler was unsafe. After understanding our needs, he gave us a range of cost effective options and made sure we knew what to expect with our decision. He arrived promptly and worked a really long day to get the job done, and we will certainly be using him for future works needed, as well as our annual boiler service.Verified reviewerJob location: LS26- AAmanda S

Excellent work,Verified reviewerJob location: LS9 10 Outstanding
Posted 14 January
My boiler was losing pressure and I was advised by another gas engineer to buy a new one. Gianne however took the time to correctly diagnose the issue - simply a blocked pipe - and repaired it. Gianne took the time to explain the issue, shared pictures of what he found and sent a service certificate with advisory notes through after the visit. I can’t recommend Gianne highly enough and would use him again without hesitation.Verified reviewerJob location: DE4

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.
