Record year for SEAI, more homes and businesses supported to reduce their energy costs in 2025 than ever before
Last year was a record year for us at Sustainable Energy Authority of Ireland (SEAI). We helped more homeowners, businesses and communities reduce their energy costs than ever before.
Tens of thousands of people in every county in the country are now enjoying more comfortable, healthier homes and workplaces and lower energy bills, thanks to a record €645 million investment made by the Government through Minister Darragh O'Brien TD Department of Climate, Energy and the Environment last year.
That is phenomenal! With every upgrade made, we are reducing Ireland's reliance on fossil fuels, putting our country on a more secure, sustainable footing.
It's that time of year when energy costs are on the minds for many, I know. We at SEAI are on hand to advise and help, no matter what stage you or your business is at. There is real momentum behind our programmes now, with something to help everyone.
Fossil fuel reliance
The long-term solution to high energy costs is to reduce our reliance on fossil fuels. Energy is central to everything we want to achieve as a country, and we must put our energy system on a more sustainable, secure footing and remove ourselves from the volatility of the international markets. Everything we do must consider and protect those most vulnerable in the transition. SEAI is here to help, no matter what stage a person or business is at.
Our 2025 Energy in Ireland report published in December shows that while we are making some progress reducing our energy related emissions, we haven’t broken the link between economic success and fossil fuels, and we need to do a lot more to meet our goals.
The good news is we know what works. Increased renewable energy infrastructure and grid reinforcement, more home energy upgrades, district heating and investment in public transport are among the many solutions that would make a big difference.
In moving away from fossil fuels, we are moving towards a more secure, healthier, more competitive economy and society for all.
We have even bigger plans for this year.
Some of our 2025 highlights include:
- Over 58,000 home energy upgrades completed (8% more than 2024).
- Highest year on record for Warmer Homes Scheme with over 8,000 homes at risk of fuel poverty receiving a free energy upgrade, lowering their energy bills and improving their health outcomes.
- Record year for solar PV - more than 102,000 homes have now been grant-aided for solar panels since the scheme launched in 2018 and a third of those happened in 2025.
- Over 18,000 motorists received grants to buy an electric vehicle and a home charger
- Over 4,500 businesses were supported to reduce their energy costs, in every county in the country.
- SEAI is Ireland’s national energy authority and the leading research body on how and where Ireland uses energy. In 2025 we awarded €22 million in research and innovation funding.
- Improving customer service continues to be a priority for the organisation – in 2025 SEAI managed over 320,000 customer contacts through our dedicated customer service teams.
