Apparently it supply and demand so it’s perfectly acceptable to profiteer and nothing we can do but accept it.
Well it is supply and demand on a global scale.
Supply has dropped due to Russia/Ukraine. The supply could be restored if we allowed it, or it will likely to go up anyway over time.
The UK individually still needs to import energy we are not energy positive. So we cannot be completely isolated from the global impact.
Now that being said we could be significantly decoupled from the global issues (ie we would have to buy less at global pricing) if we followed a national strategy of energy extraction being for the national good, but we don't.
IF we choose to nationalised energy extraction (avoiding the issues on who would be performing this etc) then we could certainly see a lower price in the UK for the combined (averaged) cost of utilities.
The public hasn't been for nationalisation of just about anything as a majority so its no real surprise than we haven't had a nationalise energy sector for some time.
The problem with attempting nationalisation during current times would be the valuation of the thing being nationalised would be well up, so nationalising it would cost us all a fortune by another door.
If we force nationalised it and didn't pay a fair price we would simply trash our global reputation, like see direct foreign investment plummet, globals pull out (to avoid risk we would nationalise that next) etc etc
