Clean Your System from the Inside Out
Over time, central heating systems accumulate sludge (magnetite), limescale and rust that clog radiators, pipework and the boiler's heat exchanger. This reduces efficiency, increases energy bills and can lead to costly breakdowns.
Power flushing forces a high-velocity, low-pressure flow of water and specialised chemicals through your system to dislodge and expel this debris. The result is a system that heats up faster, uses less energy and lasts significantly longer.
- Often required before a new boiler installation
- Works on all makes and models of system
How We Power Flush Your System
System Assessment
We assess your system's condition and take a water sample to confirm the extent of contamination.
Connect Equipment
Our professional power flush machine is connected to your system via the pump head or a radiator.
Flush & Cleanse
High-velocity water and chemical cleanser are circulated through each radiator and pipework in turn.
Inhibitor Added
On completion, a corrosion inhibitor is added to protect the system and prevent future sludge buildup.
How Much Does a Power Flush Cost?
The typical cost of a power flush is around £300 - £600, depending on the number of radiators in your home and the severity of the sludge build-up.
We'll always assess your system first and confirm the exact price before starting any work, so you know what to expect.
Does Your System Need a Power Flush?
If you notice any of these signs, your heating system likely has a sludge problem.
Cold Spots on Radiators
If the bottom of your radiators are cold but the top is warm, sludge has settled and is blocking circulation.
Slow to Heat Up
A system that takes a long time to reach temperature is working harder than it should due to blockages.
Noisy Boiler or Pump
Gurgling, banging or kettling sounds from the boiler or heating pump can indicate sludge circulation issues.
Discoloured Water
Dark, dirty water when you bleed radiators is a clear sign of significant sludge and magnetite buildup.
Rising Energy Bills
If your heating costs have crept up without an obvious reason, a dirty system could be to blame.
Boiler Cutting Out
Sludge around the heat exchanger causes overheating and lockouts. A flush can resolve this without replacing the boiler.
Power Flushing FAQs
Most power flushes are completed within a day, though larger homes with more radiators may take a little longer.
We take care to protect your floors and furnishings, and the process is carried out with minimal disruption. Your heating will be back up and running the same day.
Most systems don't need flushing every year. It's typically recommended every 5 to 6 years, before a new boiler installation, or as soon as you notice signs of sludge build-up.
Yes, a power flush cleans the system but doesn't replace your annual boiler service, which checks safety and keeps your manufacturer's warranty valid.
