The Glass & Glazing Federation (GGF) has welcomed the announcement by Ireland’s Minister for Climate, Energy and the Environment, Darragh O’Brien TD, of a new package of enhanced grants supporting homeowners across the Republic of Ireland to invest in energy efficiency upgrades, including replacement windows and doors.

The measures represent a clear recognition by the Irish Government of the critical role that building fabric improvements play in delivering meaningful reductions in energy demand, carbon emissions and household energy costs.

The announcement stands in contrast to the UK Government’s recently published Warm Homes Plan for England, in which windows and doors were notably absent from the core package of nationally funded measures. 

The GGF continues to liaise with the government in its calls for a fabric-first approach in England, arguing that effective decarbonisation of homes cannot be achieved without addressing heat loss through the building envelope.

Under the Irish scheme, homeowners in the Republic of Ireland can apply for grant support for replacement windows based on dwelling type, with grant values of €1,500 for apartments, €1,800 for mid-terrace homes, €3,000 for semi-detached or end-of-terrace properties, and up to €4,000 for detached homes. External door upgrades are also supported at €800 per door, up to a maximum of two doors.

The Sustainable Energy Authority of Ireland (SEAI) has confirmed that homeowners may apply for window grants, door grants, or both, subject to eligibility criteria including a valid MPRN and a property built or occupied prior to 2011. Detailed requirements, including BER conditions for window upgrades, are published by SEAI.

Applications for the scheme will open on Monday 2^nd March 2026. Importantly, homeowners who commenced or ordered window and/or door upgrades following the Government’s announcement on 27^th January may still be eligible for grant support, provided works are carried out by SEAI-registered contractors.

“This announcement from the Irish Government provides welcome recognition of the important role that windows and doors play in delivering energy efficiency at scale,” said Chris Beedel, Head of Government Advocacy & Stakeholder Relations at the GGF. “Ireland’s approach reflects a strong, evidence-based understanding of how building fabric improvements contribute to lower energy demand and improved home performance, and offers a valuable reference point for ongoing policy discussions.”

“The GGF is actively engaging with SEAI to further clarify requirements and to make sure that glazing is treated in the same way as other fabric measures. We will continue to work to support the effective delivery of this scheme and to ensure the expertise of our sector is fully reflected in its implementation.”

The GGF continues to work at the forefront of industry-government relations across the UK and Ireland, advocating for policy frameworks that recognise the importance of building fabric improvements as a foundation for successful decarbonisation.

The Federation encourages contractors operating in the Republic of Ireland to register with SEAI to enable homeowners to access grant support through qualified, compliant providers.
