What our clients say

“Quality. Just before going away for a pre Christmas break our oil boiler died. DCR came to the rescue and installed a new Warmflow boiler while we were away. Emily did an amazing job in liaising with us through the entire process ensuring everything went smoothly. Mathew and Logan carried out the installation to the highest standard impeccable job. Upon our return the house was spotless and warm. We could not be happier with the service provided by DCR, highly recommended for their prompt response, professional team and top notch installation.”

George Kane

“DCR were extremely helpful and professional, as another company left us without heating and hot water over the Christmas and New Year period. I called DCR and their representative Lewis turned up the next day and arranged for a new boiler to be fitted the following day. We received a first class service from them and we would definitely recommend DCR if you have any issues with your boiler, heating, radiators and hot water. A big thank you to Emily, Lewis, Jake and all the team at DCR and especially the team that turned up to help us.”

Paul

“Highly recommend DCR. They recently installed state of art air source heat pump and associated kit. Led by Lewis Morley, the team were extremely professional, kept disruption to a minimum and coped with barking dog. We are delighted with the results and pleased we did not replace our oil tank. Well done guys. 👍”

Patricia Thorpe

“We had three radiators that required fitting, two of them needed full relocation including floor removal and DCR team did outstanding job, the outcome was even better than we expected.
After the job was completed DCR team ensured that everything was working properly and didn’t leave until everything was up and running. Looking forward to working with DCR team again, if I could I would give 10⭐ Big thank you to the team who attended our property and admin Emily for great customer service.”
