We had an excellent experience with H3GS Heating. The heating service engineer was professional, efficient, and completed the repair without any delays. The company is highly responsive, accommodating urgent appointment requests with ease, and proving to be completely reliable. From start to finish, the service was seamless, and we felt reassured that our heating system was in good hands. We would definitely recommend H3GS Heating to anyone in need of a trustworthy and efficient heating service!Verified reviewerJob location: SE610 Central Heating

Installing new boiler
Elderly parents needed a new boiler. Visit arranged quickly, plenty of info with quote and a text conversation about what would suit my parents best. Date set for installation immediately and despite Barclays not paying the deposit, they turned up and did the job in a day. They were very respectful of my parents and tidy. Not only good at their job, but nice people too. Next day, I realised that the thermostat was not in the best position and they popped in the next day to reposition it. Highly recommended.Verified reviewerJob location: SE12
