Dozens of homes in south east London 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.

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.

Below is the latest figures across south east London with poor energy efficiency ratings:

Bexley

Analysis of energy efficiency ratings by the Office of National Statistics shows 68 per cent 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.

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 10,129 in Bexley.

And separate figures from charity Friends of the Earth show, as of August, 22 per cent of dwellings in Bexley did not have their lofts insulated, and 19 per cent were without cavity wall insulation – equivalent to 21,300 and 18,700 homes respectively.

Bromley

Analysis of energy efficiency ratings by the Office of National Statistics shows 64 per cent 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.

The latest figures estimate there were around 3.2 million English households in fuel poverty in 2020 – including 13,119 in Bromley.

Two in five homes in Dartford have poor energy efficiency ratings – amid warnings of soaring fuel poverty across England.

Analysis of energy efficiency ratings by the Office of National Statistics shows 41 per cent 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.

Greenwich

Analysis of energy efficiency ratings by the Office of National Statistics shows 40 per cent of houses had a ranking of "D" or below as of March 2021 – meaning they are likely to be worse impacted by the rising cost of fuel.

The latest figures estimate there were around 3.2 million English households in fuel poverty in 2020 – including 14,148 in Greenwich.

Lewisham

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

Analysis of energy efficiency ratings by the Office of National Statistics shows 48 per cent 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.

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 17,613 in Lewisham.

And separate figures from charity Friends of the Earth show, as of August, 15 per cent of dwellings in Lewisham did not have their lofts insulated, and 11 per cent were without cavity wall insulation – equivalent to 18,800 and 13,600 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.

"Those who use more energy in their homes because of medical conditions, those who are elderly and those on very low incomes need extra help, so they don’t have to ration their usage, putting their physical and mental health at risk."

Sir Keir Starmer, leader of the Labour party, said the plan "does not come cheap" and criticised Ms Truss for funding it through increased Government borrowing, rather than a one-off tax on energy companies.

The Prime Minister said it was a "moment to be bold".

“We are facing a global energy crisis and there are no cost-free options,” she said.

Chancellor Kwasi Kwarteng is set to provide more details in an announcement later this month.
