This thread is full of misinformation - it’s not helpful to other readers when people just make things up.
Global wholesale prices have been at record highs, go and look for external wholesale gas and power prices and check for yourselves.
Even where countries are putting caps and limits in place, they still have to pay the global price and will have to clawback those costs somehow through general taxation or similar. Other countries in the world aren’t paying lower prices where they are reliant on imports.
Anybody who doesn’t have a smart meter through choice is missing out on the ability to better monitor their usage. Smart meters simply communicate usage data through to a central infrastructure - they are useful to track your spend, that’s all.
Energy suppliers currently make less than 2% profit on energy supply - its heavily regulated. So for every £100 of wholesale energy you use, the supplier makes £102. That £2 is their profit for forecasting volumes, hedging, communicating with customers, regulatory compliance, network balancing etc etc. That’s why so many suppliers went bust. Some suppliers make money on energy trading, or generation - that’s business, shareholders deserve profits from a well run company - see also, supermarkets, telecoms companies, banks, and so on…….
Obviously almost all energy companies buy the volumes they need well in advance of supply and ‘hedge’ those costs. They estimate demand and buy accordingly. Only a fool would buy energy a day ahead of when they need it. Although that’s what the government did when they took over Bulb - costing British taxpayers billions more than it should have done. Hence nationalising suppliers would be a terrible idea, although they might be glad to get rid of their supply businesses - it wouldn’t make global energy cheaper though !
