Is this true re fines

[Gjggjj]

on fb someone posted ofgem charge energy co £375 for every complaint . Is that true or someone encouraging people to complain?

It's not ofgem jts the energy ombudsman.
But you can't just go straight to them with a complaint, you have to have raised the issue with the supplier first and given them a chance to resolve. If you don't have a real complaint you are trying to resolve then the ombudsman won't take on the case.

Assuming that was correct, who do you think ultimately will pay?
You. They're not going to take it out of their profits, they'll start shoving up prices to cover it.
