Unblocks stubborn deposits
Pellets physically scrape and move rust and sludge rather than relying only on chemical action.

PowDer Flush offers superior cleaning to a power flush
We recommend PowDer Flush because it provides more effective cleaning and unblocking than a conventional power flush, especially in microbore pipework, older systems and blocked boilers. Its pellets physically scrape and displace stubborn deposits at lower pressure.

Had work done by UK Power Flush Ltd?
UK Power Flush Ltd has been dissolved and isn't connected with this website. Because the company no longer exists, its guarantees can't be claimed from anyone, and we're sorry if that's left you with a heating system that still isn't right.
If your radiators are still cold, your boiler keeps cutting out or the system has blocked again after a power flush, that's exactly the kind of job we specialise in. A power flush often can't clear heavily blocked or microbore systems. PowDer Flush uses pellets to physically scrape out the rust and sludge at lower pressure.
You've paid once already, so we'll take the risk this time. With No Fix No Fee, you only pay for the flush if we get every radiator heating up over at least 80% of its surface and your hot water working properly. If we can't, you don't pay for the flush.
Former UK Power Flush Ltd customers get 10% off both Standard and No Fix No Fee prices. Just mention it when you call and have your old invoice or paperwork to hand. Your discounted price is confirmed in writing before any work starts.
UK Power Flush Ltd (company number SC795798) is dissolved. ukpowerflush.co.uk is now run by Powder Flush Ltd, which has no connection with that company, its former directors or any business they now run, and can't take on its guarantees.

WHY WE RECOMMEND POWDER FLUSH
Superior cleaning for difficult heating systems.
We recommend PowDer Flush over conventional power flushing for more effective cleaning and unblocking. Its pellets physically scrape and displace stubborn deposits at lower pressure, including where high-flow water and chemicals struggle to reach—especially in microbore pipework, older systems and blocked boilers.
Lower pressure
A lower-pressure approach can be more suitable for older systems and plastic pipework.
Microbore focus
Smaller pipework can limit water flow, making physical pellet cleaning a useful option.
THE PROBLEM
When a familiar flush isn’t the whole answer.
A conventional power flush pushes water and chemicals round your system at high flow. On a lightly sludged system that can be enough. But on heavily blocked or microbore systems the water takes the easiest route and goes around the worst blockages, so radiators stay cold and the boiler keeps struggling. That's why we now recommend PowDer Flush.

Not every cold radiator has the same cause.
- Radiators cold at the bottom or middle
- Boiler overheating or cutting out
Most cold radiators, boiler overheating and boiler faults we see are caused by sludge and rust blocking the boiler and system. Get the system unblocked and flushed first, then repair any parts the rust has damaged.
