DOZENS of neighbourhoods in Wrexham and Flintshire are set to be worst impacted by the energy crisis when the price cap rises in October, new analysis suggests.

Analysis by Friends of the Earth shows 25 out of 85 neighbourhoods in Wrexham, and 17 out of 92 in Flintshire, are at greatest risk of financial hardship when the price cap rises in October.

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.

In Wrexham, 2,110 homes require cavity wall insulation and 2,420 need loft insulation. In Flintshire, 2,470 homes need cavity wall insulation and 2,770 loft insulation. 

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.

Energy regulator Ofgem is due to announce the new price cap – which will come into effect at the start of October – on Friday, August 26.

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.

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."
