More homeowners and businesses than ever are taking control of their energy costs, with 2025 marking the highest year on record for government grants delivered through the Sustainable Energy Authority of Ireland (SEAI).
A record investment of €645 million was made last year, supporting thousands of homeowners, communities, motorists and businesses to upgrade their properties, improve comfort levels and reduce their energy bills. The increased uptake shows growing confidence in energy efficiency and renewable energy solutions as people look for practical ways to manage rising costs.
SEAI Chief Executive William Walsh said energy bills remain a major concern for many households and businesses, particularly during the winter months. He said SEAI continues to offer a wide range of grants and expert support to help people reduce their reliance on fossil fuels, no matter what stage they are at in their energy journey. He noted that there is strong momentum behind SEAI programmes, with many people now seeing the benefits enjoyed by friends, neighbours or colleagues who have already upgraded their homes or workplaces.
Last year was also a record one for home energy upgrades, with more than 58,000 completed, an increase of 8 per cent on the previous year. The Warmer Homes Scheme reached its highest level ever, with over 8,000 households at risk of fuel poverty receiving free energy upgrades. These improvements are helping to lower energy bills while also delivering better health and comfort outcomes for families.
Solar energy continued to grow rapidly in 2025. More than 102,000 homes have now received grant support for solar panels since the scheme began in 2018, with one third of all installations taking place last year alone. This made 2025 the strongest year on record for solar panel installations.
Businesses across every county in Ireland also benefited, with more than 4,500 supported by SEAI to reduce their energy use and operating costs. Transport measures were another key area, with over 18,000 motorists receiving grants to purchase electric vehicles and install home charging points.
In addition to grant programmes, SEAI continues its role as Ireland’s national energy authority and leading energy research body. In 2025, €22 million was awarded for research and innovation projects, while customer service teams handled more than 320,000 enquiries.
Mr Walsh said the long-term solution to high energy costs lies in reducing dependence on fossil fuels and building a more secure and sustainable energy system. He added that while progress is being made, continued investment in renewable energy, home upgrades and public transport will be essential to support a healthier and more resilient economy for the future.
