Mohammed is excellent. He is always on time, totally professional and helpful. My tenant is very happy, and that is important to me. I will be using Koncore Plumbing & Heating from now on. New Review April 2026: Mohammed and his team have replaced my old boiler, which had reached the end of its life and had caused a leak to the property below. A thorough investigation to check all pipework in the affected room, and removal of sodden insulation material (itchy stuff). Boiler fully commissioned, and Hive working too. Once again tenants are happy. Thank you so much once again Mohammed - you are amazing and helped me out so much.

Mo & the team did a very quick and brilliant job replacing our boiler. We have had trouble with the previous boiler for the last year and unfortunately it finally died on us. Mo had come out previously to fix the boiler and when it eventually died we came back to him and his team. Would highly recommend!

FAQ

Common Questions, Answered Clearly

Answers to the questions Hornsey homeowners ask us about powerflushing.

What is a powerflush and do I need one in Hornsey?
A powerflush clears sludge, rust and debris from your central heating. If your Hornsey radiators are cold at the bottom, slow to warm up, or your boiler is noisy, a powerflush often restores performance.
How much does a powerflush cost in Hornsey?
The price depends on the number of radiators and the condition of your system. We give a fixed, upfront quote after assessing your Hornsey home, with nothing added afterwards.
How long does a powerflush take?
Most powerflushes take between three and six hours, depending on the size of your system and how much sludge has built up. We confirm the timescale before we start.
What are the signs I need a powerflush?
Cold spots at the bottom of radiators, frequent bleeding, noisy or kettling boilers, slow-to-heat systems and discoloured water are all classic signs, especially in older Hornsey properties.
Will a powerflush lower my heating bills?
It can. A clean system circulates hot water more efficiently, so your boiler works less hard to heat your Hornsey home, which can help your bills and extend the system's life.
Do you flush the whole system?
Yes. We flush every radiator and the boiler, then add a corrosion inhibitor to protect the system going forward, giving cleaner water and more even heat throughout.

 Price depends on system size, condition and whether a filter is
included.

 It can significantly improve heating performance and efficiency

Most jobs take several hours depending on the system.

In many cases, yes, especially where sludge is the cause

It is strongly recommended for longer-term protection.
