Cost of living: Number of energy crisis hotspots in south east London

On Friday, regulator Ofgem announced the energy price cap will increase to £3,549 per year for dual fuel for an average household from October 1, 2022.  

Climate charity Friends of the Earth said there is "no downplaying" the catastrophic energy disaster facing millions of people this winter if bills rise as expected without Government intervention.

Nationally, nearly 9,000 areas have been classed as "energy crisis hotspots".

Friends of the Earth analysed smart meters and unmetered fuel consumption to determine areas where energy use is above normal levels.

It says neighbourhoods with above-average costs and lower than average household income are defined as energy crisis hotspots.

Cornwall Insights predicts that after the price cap has risen in October, an average household will pay bills of more than £3,600 per year, significantly more than double the £1,400 figure last October.

From January, this is predicted to further increase to £4,300 and the consultancy group expects bills to remain high throughout 2023.

Friends of the Earth has urged the Government to provide meaningful intervention before the autumn price cap rise instead of the "woeful and poorly targeted cash handouts" announced in April.

Below is a round up of the south east London boroughs which are estimated to be worst impacted by the energy crisis.

Bexley

Analysis by Friends of the Earth shows 37 out of 146 neighbourhoods in Bexley are at greatest risk of financial hardship when the price cap rises in October.

In Bexley, 5,310 homes require cavity wall insulation and 5,660 need loft insulation.

Bromley

40 out of 197 neighbourhoods in Bromley are at greatest risk of financial hardship when the price cap rises in October.

It means 20 per cent of neighbourhoods in the area are among the worst impacted across England and Wales.

In Bromley, 5,710 homes require cavity wall insulation and 6,410 need loft insulation.

Dartford

10 out of 58 neighbourhoods in Dartford are at greatest risk of financial hardship when the price cap rises in October – according to Friends of the Earth data.

In Dartford, 1,110 homes require cavity wall insulation and 1,520 need loft insulation.

Mike Childs, head of science, policy and research at the charity, said the Government must "beef up its package of emergency financial support" and protect the most vulnerable to soaring price rises.

The Department for Business, Energy and Industrial Strategy said it is providing £37 billion worth of support to help households during the cost-of-living crisis.

Mr Childs also said houses across the country must be more effectively insulated to protect consumers against future price rises and reduce the amount of energy required to heat homes in winter.

"The highest priority of all is fixing the UK’s leaky, inefficient housing stock, otherwise cash handouts will be required year on year," said Mr Childs.

"By rolling out a free programme of street-by-street energy efficiency measures and prioritising the most in-need neighbourhoods, we can help to bring bills down quickly, make homes warmer and slash Earth-warming emissions at the same time."

A BEIS spokesperson said: "We are investing £6.6 billion in this parliament to improve energy efficiency as part of the Government’s 'Help to Heat' programme, which is helping make households across the country cheaper to heat."
