Our process
How our powerflushing works.
1. Pre-flush survey
Radiator-by-radiator temperature readings logged so the improvement is provable.
2. Powerflush
High-flow pump connected; chemical cleaner and magnetic filtration pull out sludge and rust.
3. Inhibitor & filter
Fresh corrosion inhibitor added and a MagnaClean fitted to keep the system clean.
4. Final test
Every radiator re-read — hotter tops, hotter bottoms, faster warm-up.

FAQs
Powerflushing — your questions answered.
Do I really need a powerflush?+
If radiators are cold at the bottom, the boiler is noisy or heating is slow to warm up, sludge is the cause in most cases.
How long does a powerflush take?+
Most 3–4 bed homes take 4–6 hours. Larger systems may need a second visit.
Will it affect my boiler warranty?+
The opposite — manufacturers require a clean system, and Worcester Bosch specifically recommend flushing on boiler changes.
Is a MagnaClean filter included?+
Yes, a magnetic filter and fresh inhibitor are fitted as standard to keep the system clean afterwards.
