I power flush central heating systems in Northampton and nearby villages. It's £450 for up to 10 radiators, plus £25 for each extra radiator.
What's involved
- A pump connected to your system pushes water and cleaning chemicals through every radiator.
- Sludge and rust are flushed out of the pipes and radiators.
- The system is refilled with clean water and inhibitor to protect it.
- Each radiator is checked to make sure it heats evenly.
How long it takes
A power flush usually takes a day.

Questions
How do I know if I need a power flush?
Radiators cold at the bottom, a noisy boiler, slow-to-heat rooms or dirty water when you bleed a radiator are the usual signs.
Should I power flush before a new boiler?
Often, yes. Fitting a new boiler to a dirty system can shorten its life and affect the warranty.
Will it make a mess?
No. The work is done through the pipework, and I protect the floors around the pump.
Got a plumbing or heating problem?
Call me directly. If I'm on a job, leave a message or send the form and I'll call you back, usually within 10 minutes.
