How to complain about E.ON Next (and actually get somewhere)
A common mistake: going to Ofgem. Ofgem regulates the market but doesn’t resolve individual complaints - this is the route that does.
- 1
Complain to E.ON Next in writing

- 2
Give them 8 weeks
Suppliers get 8 weeks to resolve a complaint. If they send a deadlock letter sooner, you can skip ahead.

Escalate to the Energy Ombudsman - free
After 8 weeks or deadlock, the Energy Ombudsman can make binding decisions worth up to £10,000. It costs you nothing.
