Thousands taken to A&E as many struggle to heat homes – fears a new energy crisis could pile further pressure on hospitals
Nearly six thousand patients admitted with hypothermia, pneumonia, and excessive cold, despite living in homes they own or rent, as soaring energy bills continue to put heating out of reach Trends suggest that the emerging energy crisis caused by the war in the Middle East could also create even greater problems for UK hospitalsOver 70’s hardest hit – pneumonia cases caused by freezing weather soar 66%A landmark five-year study of hospital admissions reveals a crisis in access to affordable heating in UK homes, underscoring the human cost of the energy crisis triggered by Russia’s invasion of Ukraine in February 2022Government data confirms that many of the poorest households rely on direct electric heating, fuelling urgent calls to reduce electricity prices and protect vulnerable householdsLondon, UK – March 05, 2026. THOUSANDS of Brits have been rushed to hospital after being left to live in freezing homes – with new data pointing to the real culprit being sky high electricity prices that are leaving people vulnerable to a growing winter health threat.NHS Trusts reported a 66% surge in admissions for pneumonia, a 45% increase in cases of hypothermia, and a 33% rise in incidents of excessive cold. People aged over 70 were hit hardest, recording the highest number of hospital admissions of any age group since 2020.New figures commissioned by clean energy tech company, Aira, reveal a disturbing trend in hospital admissions for hypothermia, pneumonia and extreme cold since the energy crisis began around four years ago. The figures from 2022 to 2025 show a sharp spike across all categories, suggesting that soaring energy prices – triggered by the war in Ukraine - have had a significant impact on households in the UK. Now, with a new energy crisis unfolding in the Middle East, the trend could raise fears of higher cold-related hospital admissions and greater pressure on UK hospitals. The figures show 5,828 adult hospital admissions for cold-related conditions among people who reported they were not homeless, meaning they were living in homes they owned or rented. In England, 4,701 were admitted for cold-related conditions from 2020 to 2025, in addition to 1,127 admissions in Scotland. Aira analysed Freedom of Information responses from NHS Trusts, with 71 providing geographic data for the five-year period and nationwide data provided by NHS Digital and Public Health Scotland.The crisis exposes how Britain’s electricity pricing system disproportionately charges households who rely on electric heating, with those on electric heaters being far more likely to be in fuel poverty than those using gas.[1] New figures emerge as the Energy Company Obligation (ECO) scheme is due to end in March 2026 and industry awaits the publication of the Future Homes Standard. Matt Isherwood, Aira UK Managing Director comments, “Far too many households in Britain today are living in dangerously cold homes, made worse by electricity prices that are among the highest in Europe and the developed world. It is fundamentally unfair that clean electricity is taxed more heavily than gas. The situation could deteriorate further for households and public services if energy prices climb due to the Middle East crisis – with wholesale UK gas prices more than doubling since the war began.To fix this, we need to rebalance the cost of electricity relative to gas, introduce an urgent support scheme for low-income households, and publish the Future Homes Standard. These measures will protect health, cut energy bills, and help the UK meet its electrification and decarbonisation targets – and reduce our dependence on foreign fossil fuels.”Pippa Heylings, MP for South Cambridgeshire and Liberal Democrat spokesperson for Energy Security and Net Zero said: “Households are still struggling with the cost of living and energy prices remain about a third higher than before Putin's war in Ukraine. This is leaving too many families trapped in fuel poverty – living in Dickensian cold, damp homes.The Government must take urgent steps to bring down bills and boost living standards by fully funding and immediately removing the biggest green levy from people’s electricity bills, halving energy bills by 2035 by breaking the link between electricity and gas prices; and implementing an emergency Home Upgrade Programme. This will protect families from volatile fossil fuel costs and make homes cheaper to both keep warm in the winter and cool in summer."Madeleine Gabriel, Director of Sustainable Future at Nesta, said: “Nobody should be getting ill from living in a cold home because they can’t afford to turn up the thermostat. The government is taking action to help make heating more affordable, including committing £15 billion for home upgrades over five years, but fuel poverty remains the reality for many, including those on the lowest incomes with electric heating. Higher electricity bills disproportionately affect the poorest - to address this, the government will need to go further in cutting electricity costs."The Government provides guidance on maintaining a healthy home:Keeping your home healthy[2]Try to keep your home at around 18°C where possible, as this helps protect health, particularly for older people, children, and those with existing conditions.Heat as many rooms as you can, as unheated spaces can lead to damp and mould, which may worsen breathing problems and increase the risk of illness.Use thermal or lined curtains and close them at dusk to help keep warmth in and make the most of any heat gained during the day.Improve loft and wall insulation where possible, which can help keep heat in for longer and reduce energy costs over time.If you’re worried about keeping your home warm, contact your local Citizens Advice Bureau or council, who may be able to offer support such as a free indoor thermometer or advice on available help. -ENDS- Notes to editors Research conducted by Data News Ltd on behalf of Aira.

The calculation is based on the following assumptions: annual gas consumption of 20,000 kWh for heating and hot water at €0.135/kWh; annual electricity consumption of 2,500 kWh for appliances at €0.285/kWh; an 8kW Aira Heat Pump with 100L All-in-One indoor unit; annual electricity consumption of 4,500 kWh for heating and hot water and annual electricity consumption of 2,500 kWh for appliances using the Dolomiti Energia Flexible electricity tariff with an average rate of €0.274/kWh. German savings = up to 37%, UK savings = up to 30%Aira Home Energy System SavingsThe 90% energy bill saving is based on a comparison between the annual energy bills for a household with a gas boiler on a fixed rate tariff against the annual energy bills for a household with an Aira Home Energy System on a flexible tariff. The calculation is based on the following assumptions: annual gas consumption of 20,000 kWh for heating and hot water at €0.135/kWh; annual electricity consumption of 2,500 kWh for appliances at €0.285/kWh; an 8kW Aira Heat Pump with 100L All-in-One indoor unit; 40L buffer tank, 18 x 470W solar panels, a 13.4kWh Power Store (home battery); annual electricity consumption of 4,500 kWh for heating and hot water and annual electricity consumption of 2,500 kWh for appliances using the Dolomiti Energia Flexible electricity tariff with an average import rate of €0.258/kWh and an average export rate of €0.0936/kWh. Optimising for cost savingsIn both scenarios, all costs include appliances; the cost of purchasing, installing and maintaining the heating system is not included. Gas and electricity costs are based on current prices as of January 2026. Actual costs may vary depending on energy consumption, energy price caps and tariff rates. Consumption figures reflect a typical Aira customer profile in Italy, based on internal Aira data and modelling (2026).
