"Just had a new boiler fitted by Collective Gas, and I couldn't be happier with the service. From the initial quote to the final installation, everything was smooth, professional, and stress-free. The team was punctual, tidy, and explained everything clearly. Highly recommend them to anyone looking for reliable and skilled boiler engineers."

"I am extremely happy with the service. The two guys came to my house today and replaced my boiler. They worked all day long, even in very cold and snowy conditions, and never complained. Very professional, dedicated, and friendly. I highly recommend them to anyone!"

"Sam from Collective Gas came out for an emergency call out at 1am! My boiler was leaking very badly and he came out and made it safe for the night, then installed a new boiler within a few days. I can't recommend them enough — honestly 5 star service."
