Typical power flush £450–£1,000*, depending on how many radiators you have and the size of your system. *For unusually large homes the price may be a little higher.

What a powerflush does

From cold spots to a properly warm home

1The problem

Dirt builds up inside

Over time, dirt and rust build up inside your pipes, radiators and boiler, causing cold spots and higher bills.

2The culprit

That’s sludge

We flush the sludge out of every radiator, pipe and the boiler, then catch it on a magnetic filter.

3The result

Complete heat

Every radiator heats right across, every room warms up properly, and your boiler stops struggling.

Signs you need a powerflush

Is your heating telling you something?

A powerflush is worth doing when a new boiler or radiators go in, and whenever you notice any of these.

Slow to warm up

Rooms take ages to heat, and some never get properly warm.
