The number of people speaking to Citizens Advice who were unable to afford pre-paid energy meters was three times larger in July 2022 than in July 2021, and one million people were in arrears for electric or gas payments.[1][2] A professor at the University of Liverpool, Stuart Wilks-Heeg, commented that "almost everybody will be in fuel poverty" under the criterion in use: a household pays more than 10% of its income on energy.[3] Sherelle Jacobs of The Daily Telegraph commented that middle class families and pensioners may be unable to pay increased energy bills.[7] A windfall tax on these profits was announced in July 2022. However, energy bills are a large contributing factor to the cost of living crisis (what campaigners refer to as a "cost of greed crisis").[8][6]
