Aira redefines customer choice in clean energy with tariff-agnostic optimisation
Aira is the first clean energy tech installer to offer product optimisation against hundreds of energy tariffs Real-time optimisation with Aira Intelligence unlocks significant savings and provides greater system insightsA future-proof solution that adapts as energy markets evolve, providing customers with unparalleled choice and flexibilityFebruary 18, 2025 - Stockholm, Sweden. Today, Aira launches a first-of-its-kind capability that enables customers to synchronise their Aira Heat Pump or Aira Home Energy System with any energy tariff. People can choose from hundreds of available options, including those designed for EVs, heat pumps and a wide range of smart tariffs. By optimising directly against the customer’s selected tariff, Aira can unlock significant energy bill savings, greater performance insights and more control over how energy is used in the home. Aira is a vertically integrated, clean energy tech company with intelligent heat pumps at its core. In November 2025, the company launched the fully connected home energy system, combining the Aira Heat Pump, Power Store, Power Hub and solar panels. Powered by Aira Intelligence, the products work seamlessly together to efficiently generate, store and use energy within the home. With an increasing number of dynamic and time-of-use tariffs available across Europe, this new integration removes an important barrier to home electrification: being locked into a single tariff or energy provider for the lifetime of the product. Instead, Aira customers can select the tariff that works best for them, switch if they are not satisfied - and Aira Intelligence does the rest. Anthony Loizeau, Aira Group CEO comments, “We are proud to be the first clean energy tech installer to offer optimisation against any tariff for our Aira Heat Pump and home energy system customers. At a time when energy can feel complex and out of people’s control, new intelligence features like this unlock real savings and put the power back into people’s hands.”With today’s launch, Aira introduces new optimisation capabilities within the Aira Home Energy app, expanding consumer choice and flexibility to unlock greater savings. When people switch from a gas boiler to an Aira Heat Pump and smart tariff, people can save up to 44% on their annual energy bills, and up to 90% with the fully optimised home energy system. Kaj af Kleen, Aira Chief Product and Tech Officer comments, “Historically, heat pump optimisation was limited to a small set of tariffs from specific providers, reducing flexibility. Now, we’re giving customers unparalleled choice — optimising in real time across hundreds of tariffs with Aira’s intelligence. This is a future-proof solution that adapts as energy markets evolve, removing complexity and increasing savings potential for people across Europe.”The feature is now live in the Aira Home Energy app. Notes to EditorsFor more information, please contact: gabriella.irvine@airahome.com Download the Pan-EU press kit hereDownload the UK press release hereDownload the UK press kit hereAbout Aira Aira is a home energy specialist with intelligent heat pumps at its core.

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.
