Covering West & North West London
Older heating systems often suffer from sludge, poor circulation, weak controls or wasted heat. These upgrades can be fitted individually or combined in one visit, depending on what your system needs.
Clears sludge, rust and debris from your heating system so radiators heat more evenly and your boiler does not have to work as hard.
Captures metallic sludge before it reaches your boiler, pump and heat exchanger, helping protect the system after a flush.
Gives you better control from your phone, with schedules, app control and smarter heating around your routine.
Adjusts radiator flow so heat is distributed more evenly around your home.
Upgrade old radiator valves with TRVs so you can control heat in individual rooms more easily.
Adds protective inhibitor to your heating water to help slow corrosion and reduce future sludge build-up.
Not every heating problem needs the same fix. Cold radiators may need balancing, bleeding, valve work or a powerflush. A newer boiler may benefit from a magnetic filter. A working system with poor controls may only need a smart thermostat. We’ll check the symptoms, explain the options and give you a clear quote before work begins.

Ask on WhatsAppYou may need a power flush if your radiators are cold at the bottom, slow to heat up, noisy, or if the system water is dirty. We check the symptoms first because some heating problems are caused by balancing, valves, pumps or pipework rather than sludge.
Yes, in many cases. A magnetic filter can be fitted to an existing system, but if the water is very dirty, we may recommend cleaning the system first so the filter is protecting clean water rather than trying to catch years of existing sludge.
Usually, yes. Many existing boilers can work with smart thermostats, but compatibility depends on your boiler, wiring, current controls and whether you want simple control or zoning.
No. Heating system balancing adjusts the flow around your radiators so heat is distributed more evenly. Power flushing cleans sludge, rust and debris from inside the heating system. If your radiators are heating unevenly, we can check whether balancing, bleeding, valve work or a power flush is the most suitable option.
Often, yes. If your boiler is working but the system has poor circulation, weak controls or sludge, a heating upgrade may improve performance without a full boiler replacement. If the boiler is old, unreliable or unsafe, replacement may be the better long-term option.
