What is a home energy ecosystem – and how does it work?
A home energy ecosystem connects solar panels, a home battery and a heat pump so they work together as one intelligent system. Instead of relying on the grid for everything, your home can generate, store and use its own energy – cutting energy bills and giving you more control over how your home is powered.

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.

Poll finds MPs would back the government on electricity tax cuts
A landmark study of cross-party British MPs reveals varied attitudes towards the spark spread, home efficiency and the Boiler Upgrade Scheme. Exclusive polling has found that 48% of MPs would agree with removing levies from electricity to make heat pumps cheaper for UK households. New data shows 36% of MPs have little to no familiarity with the Boiler Upgrade Scheme.Nearly half of Westminster politicians agreed that heat pumps and solar panels will be essential for helping British households reduce their impact on climate change.Heat pump leaders are calling on policymakers to better educate the population and to lower the cost of electricity. London, UK – August 26, 2025. A new landmark study of 111 British MPs reveals cross-party attitudes towards electricity prices and taxes, home efficiency measures and broader understanding of the Boiler Upgrade Scheme. Heat pump leaders are calling for policymakers to use their influence to better educate people on clean energy-tech solutions, available incentives and to increase accessibility with cheaper electricity. Electricity tax reform – The clean energy tech revolution beginsSavanta conducted the study ‘Power Politics: Electrifying the Future of British Energy’ on behalf of leading clean energy tech company, Aira. The report found that near half (48%) of MPs would agree to reducing electricity costs to make heat pumps a more affordable alternative to gas boilers, with just 17% saying they would disagree. Overall, 34% said that they would remain neutral or would need to learn more about the benefits of cheaper electricity before backing the policy change.The findings are a boost for campaigners urging the government to invest in more education and to use their policy powers to enable households to move away from fossil fuels.In the UK, households currently pay four times more for their electricity than for gas, despite a large share of the country’s electricity coming from renewable sources such as wind, solar, and nuclear power. British households face some of the highest electricity prices in Europe, largely because about four-fifths of levies are added to electricity bills, with only one-fifth applied to gas bills, making electricity disproportionately more expensive. The study revealed a stark polarity of views among MPs, with opposition to removing levies on electricity bills driven predominantly by Liberal Democrats - 58% disagree - compared to 22% of Conservative MPs and just 10% of Labour MPs.Boiler Upgrade Scheme - Still not widely understood, even by MPsThe Aira survey explores how much MPs in the House of Commons know about the government’s flagship heat pump adoption policy, the Boiler Upgrade Scheme.Results reveal that just 8% of MPs know a lot about the £7,500 funding available to help households install a heat pump, with nearly one in ten (9%) revealing that they had never heard of the BUS. Awareness and familiarity with the Boiler Upgrade Scheme vary significantly between parties. Lib Dem MPs show the highest levels of awareness (100%) and familiarity (86%). In contrast, awareness is lowest among Conservative MPs (84%) - despite their party having introduced the policy in 2022 - while Labour MPs report the lowest familiarity at just 58%, with only 5% knowing a lot about the scheme. Overall, while almost nine in ten MPs are aware of the Boiler Upgrade Scheme, actionable and detailed understanding is low.Reducing household emissions - Sustainability starts at homeIn response to survey questions about which actions they believe would make the biggest impact in helping their constituents cut household carbon emissions, the majority of MPs pointed to home insulation (71%) and the installation of double or triple glazing (54%) as the most effective solutions.Nearly one in two MPs felt that installing renewable energy systems such as solar panels (49%) or replacing a gas or oil boiler with a heat pump (45%) would also significantly cut household emissions, showing growing support for clean energy-tech amongst British lawmakers.Helping homes switch from a gas or oil boiler to a heat pump draws mixed views across parties, with 72% of Lib Dems and 50% of Labour MPs positive about the impact, versus just 24% of Conservatives.Matt Isherwood, Aira UK Service Operations Director, said: “We wanted to find out how MPs see the future of our homes; how they think we can make them cleaner, warmer, and more affordable to run. This report shows us three things: that a strong number of MPs support heat pumps and cheaper electricity prices; that many politicians understand the role heat pumps play in reducing household carbon emissions; and that more needs to be done to educate policymakers and constituents, especially in relation to the Boiler Upgrade Scheme — the government’s flagship heat pump policy.“The growing support for lower electricity prices shows that it’s high time to get down to business and deliver the ‘big bang’ moment the heat pump industry, politicians, and British households have been waiting for — one that will supercharge the country’s adoption of heat pumps and deliver lower, more stable energy bills for everyone.”-ENDS-For more information, please contact: Gabriella Irvine, Aira Group Head of PR - gabriella.irvine@airahome.com Notes to editorsClimate Change Committee: Progress in reducing emissions – 2025 report to Parliament, June 2025Research conducted by Savanta on behalf of Aira.
