Following the 2021 gas supply reductions from Russia and Europe, an energy price crisis was triggered in the UK. This crisis caused a number of smaller British energy retail companies to fail. Larger energy companies bulk buy fuel when prices are low, which makes them less vulnerable to market fluctuations and political turmoil.
