Boiler Installation Reviews

See what homeowners across Sheffield think about our boiler installation and replacement services.

"I arranged a gas boiler service for my brother-in-law as he doesn’t do computers. Chris was very understanding and did the job within the week. Would recommend and certainly have him again."
"Chris from SAS Gas Services came to service our boiler, picked up it had originally been installed incorrectly, and took ownership of the fault for us, contacting Ideal and the original plumber who did the fitting by phone to get it all resolved for us. We have used SAS since, we were so impressed."
"Sam fitted a new boiler and en-suite in my first house and a full new heating system including boiler, pipe work and radiators. Can not fault him, did a brilliant job, professional, fast, reliable, and tidy. Always on hand when needed for servicing and repairs also. Would highly recommend."
"Fantastic! Did a 10/10 job on fixing our boiler in winter. Was out to me in less than 18 hours and got us back up and running in no time. Really reasonably priced and friendly too! Would highly recommend."
