Thorough service and friendly engineer
They are a company you can trust. They are quick at coming to sort a problem out. My recent experience of two engineers couldn’t be better, I felt safe after they left.They were both polite,friendly gave full explanation of work carried out, both what I call “old school engineers”, an asset to The Powerflush. - Martin Devine

The Powerflush top notch
The engineer arrived well within the allocated time scale. He checked the location of the jobs and got on with the installation of the new boiler. I find The Powerflush trustworthy and efficient.

Great Service
More than usual the engineer was friendly, straightforward, thorough and clearly very skilled and experienced at his job. Used The Powerflush for few years, always find them reliable, knowledgeable and value for money. Engineers are highly competent and explain everything, feel safe, our boiler is kept in top condition. - claire

Annual boiler service, great experience
The engineer contacted me to let me know he was on his way, he was on time. He was respectful of my home using shoe covers to protect my carpets. He was thorough and explained what he was doing and overall was polite and professional. - Alan Grant

Highly recommend
Following an annual service from The Powerflush, a couple of faults with my boiler were identified. A second visit was scheduled just 2 days later to resolve the issues. The engineer was polite and professional, explained the work that was necessary and was finished within the hour. Highly satisfied with the service. - Carol

Posted about a month ago (February 26, 2025)Central Heating Sludge Build-up?
Roughly 80% of Homes And Commercial boilers will break due to well-known killer, central heating sludge. This is what it will do to your radiators
- Sludge build-up contributes to a whole host of heating and boiler problems that could have been easily avoided.
- It can block pipes and radiators to a point where the heat is patchy on radiators, radiators don’t work properly or they don’t heat up at all.
- It can physically block important components such as the boilers heat exchanger which are incredibly expensive to fix.
- The heating pump doesn’t recognise the change (increase) in pressure. It will continue to pump, and the back pressure can sometimes blow the pumps seal.
Powerflush - What is it and why is it needed?
Powerflush helps deal with heating problems that you can't always see such as:
- Sludge, rust and limescale cause leaks and blocked pipes. Dirty water in pipes causes heating problems and reduces efficiency.
- Sludge build-up causes cold spots in your radiators. This means they have to work harder to heat a room, and you waste more energy.
- A clogged boiler and pump cause breakdowns. 87% of boiler breakdowns are due to dirty water in your heating system. The high amount of water flow in Powerflush will process and removes this kind of blockage.
- De-scaling and preventing central heating sludge using a Powerflush means a boiler lasts for years.
My boiler cover provider has told me to have a powerflush.
