What Our Customers Say
Rated 5 stars by homeowners and landlords across East London
“Very pleased with the service we received. My boiler broke down, they fixed it the same day. Very professional and will use them again.”
Naym Islam | East London
“We had our gas cooker installed today. It was done very quickly and efficiently with all the gas safety checks done multiple times. We didn't have a gas pipe, but they kindly brought one for us. They also helped take our old gas cooker downstairs in our block of flats for recycling. Overall very happy with the service and our gas engineer was really friendly. Very effective communication and flexibility. Will definitely be coming back in the future, thank you!”
Kulsuma Uddin | Bow, East London
“Brilliant service! I had a problem with my boiler and the fuse kept tripping whenever I tried to turn the heating on. The first engineer I called thought it could be the Delta Dore controller and wasn't sure what the problem was. I then called First Commercial & Domestic Gas Engineer, and what a difference! They came out, checked everything properly and found the actual problem was with the wiring inside the boiler. They fixed it straight away and got everything working. Really impressed with their knowledge and how quickly they found the problem. I would definitely recommend them and would use them again. Thank you”
