Very swift communication , installation of the new boiler was a bit delayed on the day and I was worried they may not be able to carry out the work, but they did! The engineers were very professional, quick, cleaned up after the installation was complete, we are very happy with all the work done and can highly recommend!

The engineer who changed my boiler was fine but the lady in charge of the booking and payment was unprofessional. She even managed to use my bank details without my permission! I paid 50% upfront on the phone, she kept my bank details and used them to get the remaining 50%. I wasn't even late or anything. She had no reason to do that and it's illegal to keep someone's card details without their permission. Don't go there, their expensive and obviously not worth it!

Professional office staff and a good swift repair to my old boiler, not happy that the plumber tried to convince me and my wife that he made gin for Harrods and Fortnum Masons in his spare time. He needs to drink less gin, he was very nice.

Flexible and efficient. Did a superb very neat job of installing a new boiler that has worked flawlessly for the three years since. Less expensive than most. Everything above board with correct paperwork and certification. Was a joy and relief to find them.
