The Local Government Association have warned that tens of thousands of poor and elderly people will face another winter of high bills and cold homes because of the failure by energy companies to deliver insulation improvements in time.
The organisation, which represents 373 councils in England and Wales, urged the companies to work with local authorities to get the work done.
Energy companies are collecting this money through a levy which is contributing to the cost of fuel bills and they have an obligation to invest it as swiftly and effectively as possible to deliver upgrades which save vulnerable people money and keep them warm and healthy this winter.
Councils understand their communities and are uniquely well placed to pinpoint the areas where upgrades will do the most good. Local authorities up and down the country stand ready to work in partnership with the energy companies to make sure the hundreds of millions of pounds of unspent money is used to deliver warmer homes and lower bills to the people who need it most.
