What is Power Flushing?
Power flushing is a deep cleaning treatment for your central heating system. Over time, sludge, rust, and scale build up inside your radiators and pipes—restricting water flow and damaging components.
A professional power flush:
- Improves radiator heat distribution
- Lowers energy bills by increasing efficiency
- Reduces boiler noise and wear
- Helps prevent costly breakdowns and repairs
- Extends the lifespan of your boiler system
⚠️ Signs You Need a Power Flush
Not sure if your system needs it? Look out for:
- Radiators with cold patches or slow heating
- Noisy boiler (banging, gurgling, whistling)
- Increased heating bills with no added usage
- Murky or discoloured water during radiator bleeding
- Frequent boiler faults or low system pressure

Power Flushing FAQs
How often should I get my central heating system power flushed?
Most homes benefit from a power flush every 5–7 years. However, if your system shows signs like cold radiators or strange boiler noises, it might be time for one sooner.
How long does a power flush take?
A typical power flushing service takes 4 to 6 hours, depending on your system size and condition. Larger systems may take longer.
Will power flushing fix all radiator heating issues?
Power flushing can solve many issues caused by sludge or debris, but if there are faulty valves, pumps, or other hardware issues, additional repairs may be needed.

Yes—when done by a professional. Our engineers assess your system before flushing and adjust pressure accordingly to avoid any damage.
