Emergency call when mum's hot water packed up completely in the other day. Colin came out despite the weather and worked in baking hot conditions (in the loft of all places) to get her hot water back on again. Above and beyond service - even checked on her the next day to make sure everything was still working. Excellent customer care.
Gas fire service was overdue and it was smoking a bit. John did a complete strip down and clean. Now burning cleanly again and much more efficient. He also gave me some good maintenance tips to prevent future problems.
What a nightmare - kitchen tap started spraying water everywhere at 7am! Called Centrona Gas and they had someone (Colin) round within 2 hours. Turned out to be a split in the pipe under the sink. Fixed quickly and no water damage. Saved my day!
Needed a gas safety certificate for my rental property. Arrived punctually and John was very thorough with all the checks. Found a minor issue with one of the gas taps which he fixed immediately. Certificate provided same day on email. Only issue was parking outside was tricky but that's hardly their fault!
The warm air heating system in our office building hadn't been serviced in years and was making terrible noises. Gary came out and gave it a complete overhaul - cleaned all the ducts, replaced filters, and now it's running like new. Staff are much happier with the improved air quality. Professional job at a fair price.
Ben was class, he came identified the issue and fixed it, he went above and beyond expectations so will defo use them agan!
Great communication, very thorough service kept me in the loop every step of the way.
Had an issue with our unvented cylinder losing pressure. The team came out, found the fault with the expansion vessel, and sorted it quickly. Clear communication and a solid job well done
Finding someone to deal with warm air heating systems is tricky these days, but John at Centrona Gas clearly knows their stuff. Our system hadn’t been serviced in years and was underperforming. John did a full diagnostic, cleaned out the unit, replaced the filter, and adjusted the airflow. It's running smoother than ever. He even explained how to maintain the unit to prolong its lifespan. Great service from someone
Had a leaking toilet that was constantly running water. Centrona Gas came out quickly and got it sorted within the hour. No mess, no fuss just straight to the point and fixed properly. Very impressed with the response time and professionalism.

We had an old, inefficient boiler that was costing us a fortune in bills and breakdowns. After getting a few quotes, we went with Centrona Gas. From the initial survey to the final installation, everything was handled professionally. The engineers arrived on time, were polite, and kept the workspace clean throughout. They explained how to use the new controls and even helped us set up the thermostat. The new system has made a noticeable difference in heating performance and our bills. Would absolutely recommend them to anyone needing a reliable boiler install.

Ben and the team arrived on tirelessly, worked neatly, and completed the installation to a very high standard. They even registered the warranty and checked everything was running perfectly before leaving. I now have a modern, energy-efficient boiler, and I’m extremely happy with the results
I contacted late in the evening about a tap that wouldn’t stop dripping, and they were able to send someone the next day. The plumber was efficient, knew exactly what needed to be done, and fixed the problem in under 30 minutes. He even gave me some maintenance tips to prevent future issues.A reliable, professional company that I’ll definitely use again
I had an issue with my boiler that was covered under my Centrona Gas service plan, and they responded immediately. The engineer arrived the same day, identified the fault, and got my heating and hot water back up and running in no time. What I really liked was the transparency no hidden charges or unnecessary upselling. The service plan has been excellent value for money, and I’m really pleased I signed up. Thanks again for the great service!
