Today it was on the news that a top energy company was being fined due to breaking the rules. Rather than a fine which will be passed on to consumers,

I propose all these public service company punishments should be customer focused, so they have to lower all prices by a certain amount or similar.

Fines are budgeted for by the largest companies and are not a deterrent. A year where profits are returned to their customers would make all companies play by the rules.
