The average household in Ceredigion, Powys and Gwynedd is paying almost twice as much as last winter to fuel their home, new figures suggest.

National Energy Action said the situation will continue to deteriorate this year as customers face spiralling energy bills when the Government's Energy Price Guarantee – which means bills for a typical household are currently capped at £2,500 per year – rises in April.

Energy usage varies throughout the UK, so we've studied local figures to work out how much an average household might pay in your area.

The latest figures from the Department for Business, Energy and Industrial Strategy show the average Ceredigion household consumed 9,750 kilowatt-hours (kWh) of gas and 3,141 kWh of electricity in 2021; in Powys those numbers were 10,005kWh and 2,916kWh; and in Gwynedd, 9,639kWh and 2,784kWh.

One kWh would run an average oven for around 30 minutes, while the median has been used to exclude extreme values which could skew the average.

At the current charging rates capped by the government, it means the average household on a variable tariff continuing to use the same amount of energy as in 2021 would be paying the following amounts per year to run their home: Ceredigion, £2,313; Powys, £2,262; Gwynedd, £2,181.

Based on prices last winter, for the same amount of energy the average household would have had an annual spend of approximately £1,236 in Ceredigion, £1,199 in Powys and £1,156 in Gwynedd – just over half as much.

Households on a fixed tariff will pay for energy at their current rate until the term comes to an end.

Adam Scorer, chief executive of National Energy Action, said the situation could worsen this year following the end of the current Energy Price Guarantee, claiming one in three households will be in fuel poverty.

Mr Scorer said this means people "will be forced to bed wearing coats, ration showers and hot water, run up huge debts or self-disconnect and go cold".

"Millions of the most vulnerable – carers, people with disabilities, those on low incomes and living in inefficient homes – are already bearing the brunt this winter," he added.

"The effects of this are devastating on both physical and mental health. Make no mistake, cold homes can kill.

"Government intervention must prioritise the most vulnerable in 2023 and beyond."

A BEIS spokesperson said it has recently launched a new campaign "It All Adds Up" to help families reduce their energy bills.

They said: "We know it is a difficult time for families across the country.

"That is why we have acted swiftly to provide support, including the Energy Price Guarantee, which is saving the typical household around £900 this winter, as well as £400 payments towards bills and £1,200 for the most vulnerable households."

Energy consultancy firm Cornwall Insights predicts the price cap regulated by Ofgem will sit at approximately £3,500 between April and June – though the typical household will be charged £3,000 at most during this period under the Government's Energy Price Guarantee.

The energy price cap is then expected to drop below Government support levels in July – Cornwall forecasts that energy bills will be around £2,800 for the average household in the final two quarters of 2023.
