At DCR, a boiler service is far more than a quick safety check. We carry out a comprehensive strip-down service, thoroughly cleaning and testing all essential components. Our engineers also identify and highlight any potential issues as part of our preventative maintenance approach, helping to reduce the risk of future breakdowns and ensuring your system continues to run safely and efficiently. Book your annual service in with DCR to avoid breakdowns over Christmas.
