Our reviews speak for themselves

Boiler Service October 2023

The Green Gas London Ltd team came and serviced the boiler after we had heating issues and problems with the boiler keeping pressure. They did the job, cleaned up and always had a smile on their face.

Installing New Radiators October 2023

I am a VERY SATISFIED customer. In advance, my requirements were discussed and agreed. On the day the works commenced, Green Gas London Ltd arrived exactly on time and completed the work quickly and efficiently with very little disruption. All my radiators were replaced and/or relocated with new. There was very little mess which was clean up immediately.

Boiler Replacement May 2022

Excellent and highly professional service: the boiler was replaced while I was travelling. The old boiler was taken away together with any packaging and building material used for the replacement. The flat was left clean as if nothing had taken place. I would highly recommend Udo to anyone needing work done to their central heating system. Impeccable!

Vailant Boiler Repair & Service November 2021

I will definitely be using Green Gas London again. The gas engineer, arrived at the time that was agreed and the work was performed very efficiently and to a high standard. The price for the repair was good too. I was also really grateful as he also took out the time to reset the daily settings for my digital thermostat.
