How much does a power flush cost?

The cost of a power flush depends on the size of your system, specifically the number of radiators. To give you an accurate price, it's best to have a chat with us as we need to ask questions to get you a clear definitive answer. Contact us for a free, no-obligation quote tailored to your heating system.

Should I power flush in winter or summer?

It's better to power flush your central heating system in summer rather than winter. When the weather is warmer, the system is generally free and moving, making the flush more effective. Most customers wait until winter when their heating fails, but this means waiting days for service during the busy season. It's best to avoid the rush and book sooner rather than later. Also, start your system and run it up during summer - think of it like a car, if you don't start it up now and then it won't want to start at all eventually, and that will be when you need it most!

Why is my central heating not turning on?

There are several possible reasons why your central heating isn't turning on: thermostat issues, power supply problems, pilot light or ignition failure, or a malfunctioning control system. If your system has sludge buildup from years of use, this can also prevent proper heating. A professional power flush can resolve circulation issues and restore your heating system to full function.

Are you Gas Safe registered?

Yes, we are fully trained, qualified, certified and insured to work on gas appliances. Our Gas Safe registration number is 555837. We are also Kamco certified and provide BS7593 quality-assured power flushing service in Manchester and throughout the Northwest UK.

Why is my central heating not producing enough heat?

Common reasons for insufficient heat include incorrect thermostat settings, dirty or clogged filters, air in the system, or a malfunctioning heating element. Sludge and magnetite buildup in your central heating system is one of the most common causes, which can be effectively resolved with a professional power flush using our Kamco equipment.

Why is my central heating system making strange noises?

Strange noises like banging, surging, or grating sounds from your central heating system are often caused by air trapped in the system, loose components, or pump problems. These are classic signs of sludge and debris buildup in your pipes and radiators. A professional power flush can resolve these issues and restore quiet, efficient operation to your heating system.

What are the signs my central heating system needs a power flush?

Key signs your system needs a power flush include: cold or lukewarm radiators (especially cold spots at the bottom), slow heating response where radiators take a long time to warm up, pump noises like surges or grating sounds, boiler noises such as bangs and sudden surges, poor hot water that runs cold when fully open, and poor circulation where pipes get clogged with sludge and debris. If you're experiencing any of these symptoms, a professional power flush can restore your system's efficiency.

How long does a power flush take?

A typical power flush takes 6-8 hours for an average-sized property with 8-10 radiators. Larger properties or systems with significant sludge buildup may take up to 10-12 hours. We never rush the job - we stay until your heating system is working properly, the water is running clear, and all radiators are balanced correctly.

Do I need to be home during the power flush?

Yes, someone needs to be home during the power flush as we require access to your boiler, all radiators, and water supply throughout the day. We'll need to run taps, adjust radiators, and test the system. We keep you fully informed throughout the process and show you the results, including the dirty water we've removed from your system.

Will a power flush damage my central heating system?

No, when performed correctly by trained professionals using proper equipment, a power flush will not damage your system. We use Kamco professional power flushing machines designed specifically for safe power flushing of central heating systems. The process actually extends the life of your system by removing corrosive sludge and debris that would otherwise cause damage over time.

How often should I get a power flush?

Most central heating systems benefit from a power flush every 5-6 years, or when you notice symptoms like cold radiators, noisy boilers, or poor heating performance. You should also get a power flush before installing a new boiler to protect your investment, and after any major heating system work. Regular power flushing prevents sludge buildup and extends the life of your entire heating system.

Barry did a great job on my house. Before he came, he had a very good questionnaire to collect my home's situation. He came on-time and check my home's setup in detail. and he did a good tunning on my heating system. also he explained to me the limitation of power flushing and what it can and cannot do. Barry is professional. I highly recommended to anyone with such a need.

Very well satisfied with Barry’s job. His professional and personal approach filled me with confidence and it was clear that he knew exactly what he was doing. He turned up on time and quickly assessed the layout on set up his gear outside the back door near to the radiator that he would tap into. He updated me at every step of the way and showed me the sludge that was coming out. He willingly dealt with 3 thermostatic valves that needed replacing. He finished up by bleeding all the rads and re-balancing where necessary. He left the job in great condition after tidying up along with relevant paperwork. Well done Barry and many thanks.

Barry provided us with excellent service. We live in a flat so we were a bit nervous about doing a power flush. Barry had to bring all his equipment upstairs and set up inside which he did with great care. He took time to plan his approach and tested the system thoroughly before starting. Our main problem was that we had a big radiator that was cold because of a block in the pipes. Barry successfully cleared the blockage and then methodically worked around the system to clear each radiator, finally adding inhibitor to keep everything clean. He explained each step of the power flush to us. The whole process took about 7.5 hours and didn't leave any mess at all. The problem radiator is now perfect and the whole system is hot. Barry is thoughtful, methodical and above all a professional. He is also a great guy to have in the house for the day. We were very impressed.

Everything from the initial enquiry, to arranging a date and arriving on time was great. Barry worked throughout the day causing minimal disruption until we were left with a clean system all ready for the colder months ahead. Barry was a thoroughly decent guy to work with and took great pride in his work. All of his positive reviews turned out to be accurate and we wouldn't have any hesitation in recommending him.

We had Pro Powerflush today to sort out a long term problem with cold radiators that others had failed to do. Barry was great and tenacious in hunting for the problem. Lifting carpets and floorboards to eventually find the blockage. Worked constantly and spent hours finding and resolving the issues. Couldn't be happier and at a fraction of the price quoted by BG. I would highly recommend Barry.

Recently had issues with sludge build up in 14yr old heating system. Boiler maintenance co recommended Barry to do powerflush & fit waterfilter. Barry is such a nice guy, knows what he's doing & does what he says. Genuinely wants his customers to be satisfied & stays until the job is done. He also changed 2 radiators at v reasonable price. Would definitely recommend him to sort your boiler & heating system problems

Barry was brilliant from booking in with him to finishing in the job. He communicated throughout to explain what was happening and why he was doing it. He was tidy in the way he worked and left it like he had never been. We recently just had an under floor heating installed and he took his time to explain how it worked and got it up and running which the builder had failed to do. He even made the boiler run more efficient due to clogging up in the system. If you feel you need a power flush on your system, done look any further. Thanks again!

Hi all this fella is one in a million answered my calls for help on a Sunday telling me what my problem was. He told me to phone him the next day when I have the power flush machine setup and he would talk me through it. He did not have to do that as it is his livelihood and how he earns his living. I would really recommend him if you need your system flushing, my heating has never worked better it is now running more efficiently the radiators have never been so hot, so it hould save on heating costs. Thanks again for all your help.

I was advised to have a Power Flush from an independent boiler service who didn't offer power flushing themselves. I shopped about and I got turned down by a different company. I messaged Barry at Pro Power Flushing , He was very helpful , very fast communication and accepted the job without hesitation. Barry got out to me very quickly , He arrived on time and carried out the power flush at a good price. He was very professional , polite and just a lovely down to earth guy. The water in my system went from dirty to crystal clear and all radiators were red hot and working perfectly. Thanks a lot Barry , I wouldn't hesitate to book with Pro Powerflushing Top man , All the best with the house move.

Barry arrived at 9.30 am the exact time he said he would arrive at and proceeded to carry out the flushing of our system. He stayed until nearly 6 pm as one of upstairs towel rails was not working properly, he got it working and then balanced the whole system. Barry was very thorough and has a passion for doing the job correctly. Our heating system is now performing much better than it did before Barry’s visit.

Barry was absolutely brilliant. Got out to us within a week of calling. We had a non-functioning radiator in the house we’ve just moved into and clearly a load of sludge in the radiator/heating system that was compromising radiator heat and putting pressure on the boiler. He arrived on time, was friendly and was a very clean worker. Barry sorted out the blocked radiator after trying a few different approaches and has saved me replacing it or pulling floorboards up which is a massive relief. He gave us some great advice about getting the best out of our heating based on the radiator layout and we’re getting him back soon to replace all the caves and thermostatic valves to future proof the system. The water running through the system was crystal clear by the time he was done with it. Absolute bargain for a full system power flush, the radiators are running the hottest they’ve probably been for years and I’ve no doubt there’ll be plenty of money I’ll save in energy bills with a more efficient system. Long term the work will have paid for itself many times over. Highly recommend Barry.

Barry let me know the issues with small microbore pvc pipes to radiators before I agreed to go for it. However after 11 hrs of non stop graft to un block the issue legs he achieved success, now heat in areas I hadn't seen heat for a long time. Well pleased I chose a "old school" conscientious bloke, who never gave up. My next step was ripping ceilings down or marine board cutting to get to small bore connections, but thankfully not required. Thanks Barry

Fantastic service from an honest trader. Barry gave our old central heating system a much needed powerflush and it's working much better now. The whole process took around 6-7 hours. Our boiler had been short cycling meaning our radiators never got very hot and the powerflush has fixed this. He added inhibitor afterwards so hopefully our system will stay working efficiently for years to come.

Had our system power flushed today by Barry from pro powerflushing extremely knowledgeable guy, I hired this company to flush out our rads and boiler system after british gas had "fixed it" (I use this term loosely)and were quoting £4500 to replace our boiler saying it was on its last legs, after doing a bit of research we decided to try a powerflush first as either way want a fresh system for it to run on if we did need a new boiler found Barry on you tube after a google search. Communication was quick and clear from the start, Barry arrived exactly when he said he would. The work was thorough, and he explained every step so I knew what was happening. Prices were fair and transparent. I’d definitely use them again. Highly recommend Pro powerflushing.

Our 15-year-old Viessmann boiler has been serviced annually and is still going strong. The zone valve and pump have been renewed in the last year. Despite this our lounge radiator hadn’t heated up for several years, and our hall and dining room radiators had recently given up the ghost. Our system is 40-years-old, so I suspected it was time to bite the bullet and go for a power flush. Google and loads of positive reviews led me to Pro Powerflushing and Barry. Six days later he arrived bang on time and set to work. Six hours later we had fully functioning and balanced central heating system again. I cannot speak too highly of Barry. He works like a trojan, knows power flushing like the back of his hand, keeps you fully informed and shows you what’s going on. And all at a price which is about 50% of what the big nationals would charge. As a further bonus, he keeps you entertained with fascinating stories of a very interesting life. Thanks, Barry, for making our home comfortable again. If you need a power flush, look no further than Barry. You won’t regret it.

Thoroughily impressed by Barry's Power Flushing service. From the off, his communications were excellent and he arrived precisely on time. We have had developing problems with the central heating system and even Barry wasn't entirely sure it could be put right. Nevertheless, he set to and eventually we had heat running through some radiators which had been cold for too long. Absolutely wonderful to have the central heating working once again. Well done Barry.
