System Cleaning
Professional System Cleaning Across Hillingdon
Every system cleaning is backed by our 12-month workmanship guarantee and carried out by Gas Safe-registered engineers with CIPHE accreditation, so safety and compliance are prioritised. We remove sludge, scale and magnetite from pipework, radiators and ancillary components to restore circulation and reduce strain on boilers. Often performed alongside power flushing, this service improves heat distribution, reduces breakdown risk and helps extend the life of boilers and radiators in Hillingdon properties.
How It Works
Initial survey & system diagnosis
A Gas Safe engineer inspects the system, checks boiler performance and identifies sludge, blockages and component wear before recommending the cleaning approach.
Cleaning & flushing
We use chemical cleaners, magnetic filters and controlled flushing (or power flushing where needed) to dislodge and remove debris from pipework and radiators.
Final tests & report
Post-clean pressure and flow checks are recorded, contaminants are tested for, and you receive a clear report plus our 12-month workmanship guarantee.
Why Choose us for System Cleaning?

Cleared pipework and radiators restore even heating across rooms, eliminating cold spots and reducing stress on the pump and boiler.
Safe, certified work

What system cleaning includes
System cleaning targets sludge, rust, scale and magnetite that build up inside central heating pipework, radiators, pumps and valves. Depending on the system we use a chemical clean, magnetic filtration and controlled flushing — often combined with power flushing on older or heavily contaminated systems — to remove deposits and protect moving parts.
