Radiator power flushing service

Power flushing is a process that clears sludge, rust, and debris from your central heating system using a specialised machine. It restores radiator performance and helps your boiler run more efficiently.

Common signs include cold spots on radiators, noisy pipes or boiler, slow heating, or dirty water when you bleed your radiators. It's also recommended when installing a new boiler onto an older system.

Most jobs take between 4–8 hours, depending on the size of your system and how blocked it is. We’ll give you a more accurate estimate when you book.

It can solve many common issues caused by sludge build-up, but it won’t fix leaks, damaged valves or faulty thermostats. Your plumber will advise if other repairs are needed.
