Central Heating Power Flushing Cost
At some point it’s likely that your central heating system will need some repairs or maintenance work carried out. One of the most common central heating problems is caused by a build-up of sludge in pipes and radiators; this can stop the heating system from working properly. To deal with this problem, it’s best to hire a heating engineer to carry out a central heating power flush, which will clear the system. The cost of power flushing will vary depending on who you hire and the extent of the problem, according to EconEnergy:
- It will cost around £300 to power flush up to 10 radiators

The type of engineer you hire will depend on what type of central heating system you’re installing:
- Gas central heating engineers – should be registered with Gas Safe, this is a legal requirement in the UK
- Oil central heating engineers – should be qualified to work with oil; ideally look for someone who belongs to OFTEC
- Electric central heating engineers – should comply with BS7671:2008 Requirements for Electrical Installations. Find out more about electrical safety regulations.
