Benefits
What a professional power flush does
Over time, sludge, rust and scale build up inside your radiators and pipes — restricting flow and damaging components. A power flush clears it all.
Even Heat Distribution
Hot radiators top to bottom, with cold spots and slow-warming patches eliminated.
Lower Energy Bills
A clean system runs more efficiently, reducing gas consumption and your monthly bills.
Quieter, Longer-Lasting Boiler
Removes the debris that causes kettling, gurgling and premature wear on key components.
Signs you need a power flush

Not sure if your system needs it? These are the most common indicators that sludge has built up:
- Radiators with cold patches or slow heating
- Noisy boiler — banging, gurgling or whistling
- Increased heating bills with no added usage
- Murky or discoloured water when bleeding radiators
- Frequent boiler faults or low system pressure
