For heating systems that are working harder than they should

Power flushing across Surrey and London

Cold spots on radiators, a boiler that's noisier than it used to be, or a heating system that takes longer to warm the house each winter are usually signs of sludge and limescale building up inside the pipework. Power flushing clears it out, so hot water can circulate the way it's meant to.

It's a mechanical clean, not a quick fix bolted on top of the problem. Done properly, it takes pressure off the boiler, evens out radiator temperatures, and can bring your heating bills back down.

How it works

Step 1
Assessment and prep
We check the system's condition and confirm a power flush is actually the right fix before isolating the water supply.
Step 2
Power flush
A flushing machine circulates a cleaning agent through the radiators and pipework, dislodging sludge and debris as it goes.
Step 3
Refill and test
The system's refilled with clean water, checked for airlocks, and each radiator is tested to confirm it's heating evenly.

Questions

Power Flushing FAQs

When is power flushing necessary?

Usually when you notice uneven heating, cold spots on radiators, unusual noise from the boiler, or discoloured water when bleeding a radiator. It's also worth doing before fitting a new boiler onto an older system.

Is power flushing safe for my heating system?

Yes, when it's carried out properly. It's a standard, well-established way to clean a central heating system and can extend the life of the boiler rather than put it at risk.

How long does a power flush take?

It depends on the size of the system and how much sludge has built up. We'll give you a realistic time estimate once we've assessed it.

Will power flushing lower my heating bills?

It can, since a clear system doesn't have to work as hard to heat your home. How much you notice depends on how clogged the system was beforehand.
