System powerflushing to clean sludge and restore heating efficiency.
* Estimates only, not a quote — typical figures from recent jobs. Your engineer confirms the exact price before any work starts.
Sludge is the silent killer of heating systems — black oxide buildup that blocks radiators, strains the boiler and sends heat straight back down the pipes. A powerflush pumps the system clean under pressure, restoring flow and efficiency.
We match you with engineers who flush properly — with the right equipment, inhibitor top-up and a before/after you can see.
Assessment: system size, radiator count and sludge severity.
Powerflushing: pulsing water and chemicals through every radiator and pipe.
Verification: flow restored, radiators heating evenly.
Protection: fresh inhibitor added so it stays clean.
Any time the system is drained, inhibitor must be replaced — it's the single cheapest protection.
A magnetic filter on the boiler return catches magnetite before it circulates. Fit one at install or the next service.
Sludge in one radiator means it's everywhere — flush before the boiler suffers.
Boiler rumbling (kettling) is scale or sludge on the heat exchanger — treat early, replace late.
As a landlord you must keep the property's water, heating, sanitary and drainage systems in good working order and fix them promptly when they fail. You're responsible for structural repairs, the boiler and heating system, plumbing and electrics. Tenants should report faults in writing — and you should respond fast, because a small leak left unattended becomes a big claim.
