Boiler Servicing Derbyshire

Reliable, Affordable Care for Your Heating System

A well-maintained boiler is the key to a warm, safe, and energy-efficient home. I’m Ross, owner of ISM Plumbing & Heating, and for over 15 years I’ve been helping homeowners across Alfreton, Sutton-in-Ashfield, Ripley, and the surrounding areas keep their boilers running at their best with honest, professional servicing.

Regular boiler servicing not only helps prevent unexpected breakdowns—it can also extend your system’s lifespan, catch faults early, and keep your manufacturer warranty valid.

Just recently, we carried out a routine service in Swanwick and discovered a worn seal that was causing a slow gas leak. The customer had no idea—but we were able to fix it on the spot, saving them from a dangerous fault and a future breakdown.

Whether you have a combi, system, or conventional boiler, we follow manufacturer-approved servicing procedures—no shortcuts, no guesswork—just proper care from someone who knows the job inside and out.

"ISM Heating and Plumbing installed a new boiler for us. We are very pleased with the work done an especially with the extra heat we are now getting from our older radiators. Ross is very clean and tidy, stopped work when we needed the toilet and tidied up during and after the work was completed. We have used his services in the past and we have always been satisfied. His prices are good. He has also located a new kitchen sink tap, we needed a special colour. Very good worker, with good prices, what more could we wish for."
