Kosta did a great job fitting us a replacement boiler and at a short notice on a Saturday. He also saved us from another company that tried to charge us nearly twice the price + VAT which was way overpriced for what it was. He was very kind at explaining how our new thermostat worked too. We can't thank him enough!
Reviews from Google · 2 May 2026To say excellent is a total understatement. I live in Derby and I was unable to source a boiler to be installed. This team are professional, I had to trust them and they delivered above and beyond. Communication was just outstanding. Im terms of price again, they were most defo unbeatable. All I can say is a massive thank you sincerely and please continue to be the best at what you do. I would recommend you 1000%
Reviews from Google · 6 Apr 2026Thank you, Kosta and DMK staff for changing our boiler so fast. Friday Kosta came over on an emergency call-out. Monday we have a new boiler up and running. The staff were very helpful, explaining all the steps of what they were doing, and how that will be better for us in the long run. They asked me to call them whenever we need. Highly recommended.
Reviews from Google · 17 Feb 2026Konsta has been absolutely incredible from start to finish. Diagnosed the issue straight away and suggested reasonsable solutions. Worked so well we asked him to come back and complete several other smaller jobs. I will be recommending Konsta/DMK to everyone who asks about a plumber! Honestly cannot thank him enough for fixing the heating! 11/10 stars!!!
