I can certainly recommend DCR for heating and hot water design and installation. DCR have maintained my system for a number of years and recently upgraded my hot and cold water boost pumps providing the property with continuous hot water and excellent water pressure throughout. Lewis and his team are unfailingly punctual, reliable and tidy. In solving problems (never of their own making) DCR has always demonstrated the responsiveness and expertise we all hope for.
