Boiler Repairs in Alfreton, Derbyshire

Fast, Reliable Heating Support from ISM Plumbing & Heating Alfreton

If there’s one thing you don’t want to gamble with in Derbyshire, it’s your heating—especially when temperatures drop. I’m Ross, owner of ISM Plumbing & Heating, and for over 15 years I’ve been helping homeowners across Alfreton, Sutton-in-Ashfield, and the surrounding areas stay warm, safe, and stress-free.

Not long ago, I got a call from a family in South Normanton—their boiler had packed in the night before hosting relatives. Within hours, we had a new system installed and the heating back on well before guests arrived. That’s why we offer fast-response boiler installations and same-day service whenever possible—because no one should be left without heat or hot water when it matters most.

Whether you need a full replacement, a quick boiler swap, or an upgrade to a more energy-efficient system, we’ll talk you through your options clearly and carry out the work to the highest standards. At ISM Plumbing & Heating, we’re not just gas engineers—we’re part of your community, and we take pride in doing the job right.

"Ross can be trusted, he does an excellent job for a very fair price. He is clean and tidy, clears any mess after and during working. He has fitted a new boiler for us, and made a follow up visit to make sure we were happy and rechecked the system. He has since found a tap of the colour we wanted and fitted it. I have found his prices to be very good and definitely competitive. Thank you Ross."
