I recently requested an annual servicing of my gas boiler and I was very happy with the service, here's a quick summary: 1.) Easy booking via online form; 2.) Engineers arrived promptly as per time slot I booked; 3.) Engineers were polite and friendly and based on my (layman) understanding, the servicing was carried out thoroughly as per checklist; 4.) Price was reasonable and inline with my expectation; 5.) Electronic card payment option available (no cash required); 6.) Receipt and servicing certificate / checklist issued electronically in printable PDF format; 7.) Aftercare also confirmed that company is reachable and responsive via phone and / or email which is good to know going forward. As the company who installed my boiler originally is no longer operating, I was looking for an alternative option for annual servicing and therefore this was my first time liaison with Belfast Gas and based on my experience, I will definitely recommend them and will also utilise them going forward. Thanks again! -Vesa

Needed our gas boiler serviced and was lucky to get an appointment the following day. Very professional and friendly guys who also detected a minor leak that they were then able to repair and correct. Highly recommended!!!!!
