Mohammed is excellent. He is always on time, totally professional and helpful. My tenant is very happy, and that is important to me. I will be using Koncore Plumbing & Heating from now on. New Review April 2026: Mohammed and his team have replaced my old boiler, which had reached the end of its life and had caused a leak to the property below. A thorough investigation to check all pipework in the affected room, and removal of sodden insulation material (itchy stuff). Boiler fully commissioned, and Hive working too. Once again tenants are happy. Thank you so much once again Mohammed - you are amazing and helped me out so much.Posted on Google![]()

Mo & the team did a very quick and brilliant job replacing our boiler. We have had trouble with the previous boiler for the last year and unfortunately it finally died on us. Mo had come out previously to fix the boiler and when it eventually died we came back to him and his team. Would highly recommend!
