I had a fantastic experience with this service! They arrived right on time and worked efficiently while keeping the area clean and tidy. I appreciated that they wore sleeves over their shoes to protect the carpet, which showed real attention to detail. The team was very friendly, helpful, and professional throughout. They even replaced the heater temperature gauge without any extra charge. Overall, great guys and outstanding service—highly recommended!

Brilliant service by the two gentleman who arrived to repair our boiler. After a short conversation with the engineers, I grasped they are very experienced. They were straight to the point when it came to the repair and did not waste any unnecessary time which other companies do which adds to the bill. Many thanks

Brilliant lads! Extremely polite and friendly. Came out quickly and had all parts needed to fix and replaced mid position valve. Reasonably priced and efficient. Really impressed with their work. I have called them out twice for 2 different jobs and will call again if needed! Totally recommend!!!

I have used GU Gas Services for three years for my annual boiler service. They arrive on time to service my boiler and an additional water heater. Two very nice guys who do their work quickly and efficiently. I would not use anyone else now. I cannot praise them highly enough.

I've used the boys from GU Gas Services multiple times, and they’ve consistently delivered outstanding service. They are always quick to arrive, diagnose the issue promptly, and carry out the work to a high standard. They also make sure everything is left clean and tidy, which is much appreciated. On this latest occasion, I had some boiler issues. True to form, they were quick to respond, identified the problem efficiently, and completed the repair with a thoroughly professional approach. I can’t recommend them highly enough for their reliability and excellent workmanship! Thanks Guy's!
