Our powerflushing in Tonbridge clears internal blockages and restores proper flow right through the system, improving radiator performance, supporting better hot water circulation and keeping your heating running efficiently. If your system is older, or you are planning a new boiler, a power flush first ensures it is clean and ready to run efficiently. In some cases these symptoms point to the boiler itself; where faults or inconsistent heating continue, our gas boiler service can diagnose and resolve the underlying problem alongside the clean.
Common signs your heating system may need powerflushing include:
A full power flush that removes sludge, corrosion and debris from your central heating system, restoring proper circulation and improving overall heating efficiency.
Targeted cleaning to clear blockages from radiators, eliminating cold spots and letting heat spread evenly throughout your Tonbridge home or commercial building.
Professional flushing of the boiler, pipes and pump to clear internal build-up that reduces performance and leads to a noisy boiler or low water flow.
Before a new boiler goes in, we carry out a full system flush to remove existing sludge and debris, so the new heating system runs at optimal efficiency from day one.
Fast-response powerflushing for heating systems facing severe blockages, poor heating performance or sudden system pressure issues.
Specialist powerflushing in Tonbridge for commercial properties, offices and larger buildings whose heating systems need professional cleaning for efficient, consistent heat flow.

The cost depends on the number of radiators and the size and condition of your system. A power flush typically costs between £300 and £600, with larger or heavily sludged systems costing more. For any Tonbridge property, we give a fixed quote up front after assessing your system, so you know the exact price before any work starts.
A typical home with around five to eight radiators takes roughly three to six hours. A larger property, or one with badly sludged radiators, can take a full day. We give you a realistic time estimate with your quote.
We do not recommend it. A proper power flush needs a dedicated high-flow pump, the right cleaning chemicals and safe disposal of the waste water, and an inexperienced flush can dislodge debris or expose weak pipework. It is a job best left to a qualified engineer, and our Gas Safe team covers Tonbridge and the surrounding area.
Carried out correctly by a professional, no, the flow is high but the pressure is carefully controlled. The only real risk is on an old, already-corroded system where existing weaknesses can be exposed, which is why we inspect every Tonbridge system first and adjust our method on older properties before we begin.
With a working corrosion inhibitor in place, roughly every five to six years. If you are seeing dirty bleed water or new cold spots sooner than that, the inhibitor has likely worn out and it is worth a check.
In most cases, yes. Fitting a new boiler to a dirty system can clog it quickly, and most manufacturers require the system to be cleaned for the warranty to stay valid.
