Deep Clean Your
Heating System

A powerflush is a deep clean of your central heating system. Using a specialist machine, we pump a cleaning solution through your boiler, pipes and radiators at high velocity to remove the sludge, rust and debris that builds up over time. The result is a system that heats up faster, runs more efficiently and puts less strain on your boiler.

Common signs include radiators that are cold at the bottom but warm at the top, some radiators that never get warm, a boiler that keeps cutting out, noisy pipework or a boiler that runs but the house does not heat up properly. If you are noticing any of these, a powerflush is often the fix.

Our powerflush service starts from £350. The final price depends on the number of radiators and the condition of the system. We will give you a fixed price before we start.

Most powerflushing jobs take between four and eight hours depending on the size of the system and how heavily it is contaminated. We will be able to give you a better estimate once we have had a look at your setup.

In most cases, yes. Sludge and debris is the most common cause of cold radiators and an inefficient heating system, and a powerflush clears it out effectively. If there is an underlying fault with a specific radiator or the boiler itself, we will flag it during the job.

Gas Safe Register is the official, government-approved list of engineers who are legally allowed to work on gas appliances and installations in the UK. It replaced CORGI in 2009. Our engineers are Gas Safe registered, which matters because a powerflush involves working directly on your gas boiler.

We cover Harrow, Wembley, Pinner, Stanmore and Kenton as our core North West London area, plus Watford, St Albans, Hemel Hempstead, Luton and the surrounding areas.
