How Much Does
A Powerflush Cost?
Power flushing is the process of cleaning the central heating system – including the radiator, pipes, and boiler itself – to improve its performance.
This involves flushing out all the debris and sludge that’s built up in your heating system over the years.
From improved performance and energy efficiency to fewer breakdowns, power flushing offers many benefits, but it’s important you’re aware of the costs before requesting our services.

How Much Does A Powerflush Cost?
Let's talk in detail about how much does a powerflush
cost in various situations.
Powerflush Cost depends on:
- Property type and size – The bigger your property, the more expensive a power flush will be.
- Number of bedrooms – again, the more rooms in your home, the pricier a power flush will be.
- Radiators quantity – the more radiators you have, the longer a power flush will take to perform, and so will cost you more.
- Underfloor heating circuits - this can make power flushing much more complicated and time-consuming and may require specialist equipment.
- Type of heating system – some systems are more complicated to flush than others, so therefore will be more expensive.
Benefits of Poweflushing Heating System:
As we mentioned earlier, regular power flushing has many benefits for your central heating system:
- Reduced energy bills – After a power flush, homeowners have been able to save up to 40% on their subsequent energy bills.
- Increased heat output from your radiators – The gunk in your system’s pipes prevents your radiators from warming up properly, but you’ll feel the benefit once everything has been cleared
- Increased lifespan – Power flushing is a key part of central heating system maintenance, and if you keep up with it, your system could last you upwards of 15 years!
- Reduced risk of breakdowns – The majority of boiler breakdowns are caused by dirty water in your central heating system. Regular power flushes help clear the system and, therefore, prevent breakdowns.
- Corrosion prevention – A build-up of dirt and sludge in your central heating system pipes is the main cause of corrosion, so a power flush will, of course, help stop this from occurring.

Frequently Asked Questions
How can I tell if I need a power flush?
If you can’t remember when you had your last power flush, there are some red flags you can be looking out for:
- Excessive banging or rattling sounds coming from your heating pump or boiler
- Radiators are slow to warm up
- Some radiators struggle to warm up more than others
- Discoloured water, or no water at all, when bleeding

What’s involved in the power flushing process?
During a power flush, a powerful pump is connected to your central heating system – to the pump head or circulation pump depending on the type of boiler you have.
Once connected, this pump flushes a cocktail of chemicals through the pipework to dislodge all of the gunk clogged up within and prevent rust and limescale from wreaking havoc on your system in the future.
After everything has been cleared we’ll force clean water through your pipes to remove all traces of contaminated liquid from your system, before properly disposing of the waste.
Is power flushing always necessary?
9 times out of 10, power flushing will cause all of your central heating issues – so it shouldn’t be seen as an optional maintenance job.
If your boiler is under 15 years old, power flushing is the most effective way to keep it running at its full capacity and should help prolong its lifespan. Without them, regular repairs are highly likely, and you may need to replace your central heating system sooner than necessary. So, when you consider these costs, compared to the cost of a power flush, it’s more than worth it.
However, a power flush won't solve issues with pressure loss or faulty parts – so it may be worth looking into other repair options or replacing your boiler altogether.
