I rang Belfast Gas after my previous (ancient) boiler had finally given up. They were able to explain advantages and disadvantages of the options available to me, when I decided on replacement, it was installed on the arranged date professionally and efficiently with no disruption to me working from home the same day. The lads were great to deal with and answered any questions I had for them. Impressive workmanship, personable staff, would highly recommend.
