Oil and gas produced is sold on the world market and suppliers have to buy on the world market, consequently we pay high prices because suppliers are paying market price and the producers make huge profits from selling the same. Sunak gave the go ahead for lots of new oil fields consequently huge profits for oil companies and lots of taxes on it to fill govt coffers, meanwhile we get raped because market prices. Meanwhile the govt scrapped the agency that was promoting home insulation and blocked the cheapest form of energy, wind onshore and effectively offshore by offering so low a price for generation that no producers could be persuaded to buy a single contract. Yes, your government is screwing you over. What a life, eh.
Oh forgot to mention - govt have recently blocked new solar farms from being built on farmland so no cheap solar energy, all to avoid spoiling the view from Tory shire MP's constituency windows, probably.
