Octopus Boss Warns UK Is Too Exposed to Global Gas Prices

Jackson, founder of the UK’s biggest household electricity supplier, said: “The government’s decision to take VAT off electricity and remove some of the levies from bills has helped soften the blow this winter, but bills are still too high. “Britain remains far too exposed to volatile global gas prices.
