How Much Does

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.

The cost of a power flush varies depending on a number of different things, such as:

Of course, all companies are different – with some charging per job and others per hour. So, the cost of power flushing will also vary depending on the company you choose.

Prices can be more expensive for those who live in major cities, so this is another thing to keep in mind.

What’s included in the cost of power flushing?

How often should I have my system power flushed?

If you’ve recently had a new boiler fitted and it’s under 4 years old, there’s no real need for regular power flushing.

After this point, you should be able to get away with power flushing radiators every 5-6 years, or every 8-10 years, but this depends on the quality of the materials used in your system and how well you take care of it.

Why hire an expert power flushing engineer?

If your central heating system isn’t working properly and you want to get it fixed, rather than replacing it altogether, power flushing is the best option.

However, it’s important to note that power flushing isn’t a ‘do-it-yourself’ kind of job, and you’ll need a professional engineer to do it for you. This is where we come in.

We have all the knowledge and tools required to carry out a power flush, and you can be confident that your central heating system is in the best hands with us.

Boasting a 5-star rating, our past clients have left countless glowing reviews – check them out and see for yourself why working with us is so great!

Is Power Flushing Always The Answer?

9 times out of 10, a power flush will solve any issues you’ve been experiencing with your central heating system.

However, a power flush won’t solve problems like pressure loss or faulty parts, so in these cases, you’ll have to look into alternative repair options to get your boiler back on the mend.

Something else you should take into consideration when deciding on whether or not to get a power flush is the age of your central heating system.

A boiler replacement may be more cost-effective than maintenance and repairs, especially if your system is older than 15 years and you’re having reoccurring issues.


How should I prepare for a power flush

All you need to do before our engineers arrive is switch off your boiler, open all the radiator valves, and shut off your water supply.

There’s no need to remove any of your radiators, as this would make the cleaning of the pipes almost impossible.

Doing this will help save us some time, but if you need any assistance, be sure to let us know and we’d be more than happy to help!



How does a power flush work and how long does it take?

Typically, a power flush takes less than a day for our engineers to complete, but this depends on the size of your property and how many rooms/radiators you have.

Regardless of the number of radiators, the power flushing process will be the same.

First things first, we’ll connect a powerful pump directly to your central heating system – either through the pump head or circulation pump, depending on the type of boiler you have.

Once this pump is connected, we’ll flush a powerful chemical cleaner through the pipework to remove sludge buildup and destroy limescale, which should prevent rust buildup from reoccurring in the future.

After we’re sure we’ve dislodged all the build-up inside your pipes, we’ll force clean water through the pipes to remove the contaminated liquid from your system, before properly disposing of it.


What’s the difference between a chemical power flush and chemical flush?

Although power flushing and chemical flushing may sound the same, the processes do differ slightly.

During a central heating power flush, cleaning chemicals are pumped through your pipes to clear any build-ups of rust, limescale, and any other sludge or debris.

Chemical flushes, on the other hand, use gravity to flush the system and refill it – with the cleaning chemicals dispersed and left to mix throughout your central heating system for a few days.

A central heating system power flush is much more thorough and doesn’t need to be performed as often as a chemical flush. If you ask us, it’s a no-brainer.


How can I tell if my central heating system needs a power flush?

Ideally, you shouldn’t leave any longer than 5 years between power flushes, but if you can’t remember when your last one was done, there are a few red flags you can look out for to tell you it’s time:

  • Cold spots on your radiators, or hot pipes and cold radiators
  • Inconsistent flow of hot water
  • Radiators take longer than usual to heat up
  • Noisy boiler
  • Radiators need bleeding constantly and produce discoloured water when bled
  • Noticeable difference in radiator function

There’s no denying the benefits of regular power flushing, so if you happen to notice any of these signs, give our experts a call to get your next power flush booked.

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

    If you notice any of these signs, be sure to contact our expert power flush engineers today for a competitive, no-obligation quote or to book your appointment.

  • 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.
