What is powerflushing and does my heating need it?

Powerflushing is a deep clean of your central heating. Over time, sludge and rust build up inside radiators and pipework, causing cold spots, noisy boilers and higher bills. If your radiators are cold at the bottom, slow to warm up, or your boiler is noisy, a powerflush can restore even heat and help it run efficiently.

A deep clean that clears sludge so radiators heat evenly and the boiler runs better.

Restore your heating to full performance

If your radiators are cold at the bottom, slow to warm up, or your boiler’s making noises, the likely culprit is sludge — a build-up of rust and debris inside your heating system. A powerflush clears it out, so heat flows freely again and your boiler doesn’t have to work as hard.

The signs of a sludged system

  • Radiators cold at the bottom or in patches
  • Rooms that never quite get warm
  • A boiler that bangs, gurgles or kettles
  • Dirty, dark water when you bleed a radiator

Done properly, protected afterwards

We don’t just flush and leave. We add a corrosion inhibitor to slow future build-up, and we check every radiator heats evenly before we’re done — so you feel the difference straight away.

How it works

What to expect

  1. Assess

    We check your system for the signs of sludge and cold spots.

  2. Flush

    We circulate a cleaning solution to break down and remove the debris.

  3. Protect

    We add inhibitor to help keep the system clean for longer.

  4. Test

    We check every radiator heats evenly before we finish.

Frequently asked questions

How do I know if my heating needs a powerflush?

Tell-tale signs include radiators that are cold at the bottom, take a long time to warm up, need frequent bleeding, or a boiler that's noisy. Dirty water when you bleed a radiator is another clue.

How long does a powerflush take?

Most take a day, though larger or heavily sludged systems can take longer. We'll give you a realistic estimate after assessing your system.

Will a powerflush fix cold radiators?

If the cold spots are caused by sludge — which is common — then yes, a powerflush usually restores even heat. If the cause is something else, like trapped air or a valve issue, we'll tell you honestly.

    Jordan recently installed a new boiler, cylinder and connected up my underfloor heating. Communication was excellent from start to completion and the work was neat and tidy.

    We're really pleased with the air conditioning installation. From start to finish, the staff were great — friendly, helpful and professional. A special mention to the fitters, Tom and Ben, who did a fantastic job. They were polite, tidy and worked efficiently, taking care to make sure everything was fitted properly and left clean and tidy. The whole experience was excellent, and we wouldn't hesitate to recommend them to anyone looking to have air conditioning installed. Great service from a great team!
