My boiler broke down unexpectedly and required a replacement. From the engineer who broke the news through the office staff organising prompt quotes and a swift appointment, and the engineers who fitted the replacement I couldn’t be more thankful. Professional, friendly and courteous service throughout. Highly recommend!

Mains Gas has my business!

I decided to try Mains Gas having been with another company for some years and being unhappy with certain aspects, particulary price. Mains Gas has just serviced my gas fire and boiler/central heating etc.I was impressed by their punctuality and attention to detail and explanation of actions being taken during service. I have just paid the invoice and was pleased with the very competitive price. I intend to continue to use Mains Gas services in the future.

Boiler Maintenance Feedback

We recently had our boiler serviced and wanted to share our experience. The technician was punctual, professional, and knowledgeable. The maintenance was carried out efficiently, and everything was explained clearly. We now feel more confident that our boiler is running safely and efficiently.
We’d also like to thank the admin staff, who were friendly, helpful, and made the booking process smooth and hassle-free.
Thank you for the great service – we would definitely recommend your company to others and will use your services again in the future.
Kind regards, Larissa & Lyndon
