How we check grant figures

• Official sources only: SEAI for energy grants, Citizens Information and gov.ie for local authority grants, and lenders’ own pages for green mortgages.
• Read at the source: we read each official page directly rather than relying on summaries, which often mix up grant amounts with typical costs.
• Dated: every guide shows the date it was last checked, and links to the pages it was checked against.
• “Up to” means the maximum: most grants are fixed amounts by home type, and a grant can never be more than the cost of the work.

Typical costs are SEAI’s published median costs of grant-aided upgrades completed from January to June 2026. A median is the middle of past costs, not a quote: your price depends on your home and the scope of the work. Where we have no official cost figure, we say so and suggest getting written quotes. Our upgrade comparison puts grants and costs side by side.

• We re-check the guides when SEAI or the government announces a change, such as a new grant, a new amount or the BER scale change of May 2026.
• The home explorer on our homepage uses the same official grant figures as the guides. Typical costs are guidance, not a contractor’s quote or confirmation of grant eligibility.
