Not all power flushing methods give the same outcome
With ongoing hands-on work, we’ve developed a structured approach that avoids guesswork and delivers lasting results. Our consultancy passes on this practical insight - so you understand how to carry out each job properly, using the right tools, steps, and judgement.
Over time, we’ve found what genuinely works and why some common approaches fall short. It’s this hard-earned knowledge we now share with engineers keen to do things better.
Offshore experience applied to domestic heating systems
With over 25 years of experience in demanding offshore environments, founder Richard Knight brings a level of detail and care not often seen in domestic heating.
His background includes:
• Platform shutdowns
• Nitrogen purging of pipelines
• Hydrostatic pressure testing
• Nitrogen/helium leak detection
This background has helped shape a consultancy that’s precise, practical, and built around strong procedures. We apply this knowledge directly to domestic power flushing.

What Our Customers Say
“Just had Richard come to do a power flush on my central heating system. It’s a fairly new installation fitted in 2019 but had lots of issues with the heat exchanger clogging up. I was advised to get a professional company to carry this out, and he really seems to know what he is doing. Very methodical, neat and tidy, and respectful of your property. He went above and beyond as far as I am aware and would definitely recommend. Hoping that this has helped solve my boiler problems but time will tell. To be honest, he showed me how much came out of my system and I was surprised.”

“The RAK power flushing team spent a day at my house clearing all of the debris that had built up in my 15 radiator system. It was quite alarming to see how much sludge had built up over the years as well as other issues with valves etc. that had potential to cause big issues in the future. The team worked non-stop and into the evening to complete the job and I am now confident that my system is clean, safe, and working efficiently.”
