Have been trusting Dmitry over the past 4 years with my annual boiler maintenance and flushing of my radiators. Professional, reliable, very clean and polite. Highly recommended.

I have used this service several times and I should say that Dmitry is the best plumbing, heating and electrical engineer I’ve met in London. He managed to fix the problem and worked out the solution. Dmitry is really experienced and superbly qualified. Highly recommended!

Great experience with Demeter! Highly recommended! We have used him for our boiler service and also installed a new sink and mixer in the kitchen and he has done great work. He is also very responsive and helpful when you have questions. Thanks !

Dimitry is the best plumbing, heating and electrical engineer I’ve met so far! He thoughtfully diagnoses the problem and works out the solution. Dimitry is experienced and superbly qualified. Thanks for helping us out again.

Very warm recommendation. I have been using Dimitri's services for the past 2 years. As part of a major refurbishment in a London flat with 4 bathrooms. Then to ensure a proper yearly check up on the boiler, the hot water cylinder etc Very reliable, very knowledgeable. On time. Fully trustworthy. It's hard to come by a contractor of this quality.
