Two-thirds of homes in Coventry have poor energy efficiency ratings – amid warnings of soaring fuel poverty across England

Two-thirds of homes in Coventry have poor energy efficiency ratings, figures show, as campaign groups warn of soaring fuel poverty even with the new Prime Minister's energy plan.

Prime Minister Liz Truss announced that energy bills will be frozen at no more than £2,500 a year for all homes in England, Scotland and Wales, as part of a package of support aimed at tackling the cost-of-living crisis.

However, the End Fuel Poverty Coalition campaign group said the new measures would be an "expensive sticking plaster" if they were not accompanied by longer-term investment in energy efficiency and renewables.

Analysis of energy efficiency ratings by the Office of National Statistics shows 66% of houses had a ranking of "D" or below as of March 2021 – the latest figures – meaning they are likely to be worse impacted by the rising cost of fuel.

Energy Performance Certificates show how effective a home is at keeping heat in – with ratings from A (the most efficient) to G – the least, meaning residents have to spend more on energy bills to keep their homes warm.

The End Fuel Poverty Coalition estimates that 6.9 million households across the UK will suffer fuel poverty this winter, even after the new price guarantee – including around 5.3 million households in England.

The latest figures from the Department for Business, Energy and Industrial Strategy estimate there were around 3.2 million English households in fuel poverty in 2020 – including 28,208 in Coventry.

And separate figures from charity Friends of the Earth show, as of August, 18% of dwellings in Coventry did not have their lofts insulated, and 13% were without cavity wall insulation – equivalent to 25,900 and 19,100 homes respectively.

Adam Scorer, chief executive of fuel poverty charity National Energy Action, called the PM's announcement "good news", but warned more must done for those most in need.

"The new Government must not forget that the most vulnerable need targeted support," he said.
