New combi boiler fitted and old one removed along with the water tanks and cylinder. Dylan, Andrew, James and Jordy made a very hard job look easy, that was easily 2 days work squeezed into one. They didn’t leave any mess behind either, everything was well cleaned up before they left. Thanks lads great job"

Thanks Lads
Great Job- Gerard O’Connor - February 2025

I wish I had of upgraded sooner to this combi heating system. I found a massive difference in my power shower and instant water with portable digital controller. The guys were terrific, clean and tidy and exceptionally professional. Such a brilliant job carried out with precision and perfection. Quote the same day with options and installation a week later. Powerful job and I highly recommend this company."

Fantastic Job- Elaine Curry - February 2025

I had a new boiler fitted by two Safe Gas engineers. They did a fantastic job, took old boiler and any trash away. They were friendly and professional. He also took time to explain everything about the new boiler. Would highly recommend Safe Gas to anyone."
