  • After having a bad experience with an installer I was reluctant to try another boiler installers, however, because of a broken boiler and on the insistence of a friend I chose to contact Domestic & General Heating. The person on the phone was very courteous and I actually felt comfortable talking to a complete stranger. The engineers that came to my house were thorough professionals and carried out the whole installation very professionally.

  • These guys think out of the box, for the last few months I had been going around to find someone who could fix a weird sound from my boiler. Many people tried to figure what was wrong but failed. The DG guys however, made my day by not only fixing the problem but also servicing my central heating system. Now there isn’t any cracking sound and I can actually sleep very well. A job well done DG heating.

A very professional & competent staff. These guys actually know what they are doing. Had problems with my wall insulation and these guys covered everything in half the price of what others were offering. With my house insulated the heat efficiency has gotten better thanks to DG Heating. Cheers guys!

A company that actually do’s what it says, I had a great time with these people, not only did they install a new boiler but also gave me an extended warranty. The work was tidy and the installers made sure not to damage any walls from the inside and outside.


"Okay so these guys have a great customer support staff, the guy that I talked to was very helpful, very happy with the cavity wall insulation that I got."


"I got good value for money, nice people and professional staff. Loved the boiler these guys installed."




" Punctual and professional in servicing, couldn’t pay for a new boiler so got a great deal on boiler finance from these guys"
