As a result one in 10 households is already living in fuel poverty, according to the latest official government figures, while the Department of Energy and Climate Change has predicted that the number will climb by around 5% this year.
Problems will continue in the future with the Government calculating that average household energy bills in 2030, for example, will be 18% higher in real terms compared to 2013.
“This is of particular concern given that the poorest households are hit hardest by increases in bills,” Hodge said. “Poorer households spend more of their incomes on household bills relative to richer households, meaning that funding infrastructure through bills is more regressive than doing so through taxation.”
She has demanded that the Treasury produce and publish an assessment of the long-term affordability of bills across the sectors. “They need to establish with departments and regulators who is responsible for what in each sector when it comes to assessing the long-term affordability of bills, and pull all the information together.
“Crucially, they need to assess the combined impact of increased bills on different household types, including those households most vulnerable to price rises.”
She said regulators must also play their part by having a co-ordinated approach to assessing the impact on bills and affordability of infrastructure investment, in collaboration with the Government.
“We also need to be reassured by regulators that infrastructure has been built to the standards expected, to improve their protection of consumers’ interests,” she added.
