SEAI insulation grant amounts depend on the type of upgrade, your home, and the scheme available when you apply. Eligibility can be affected by factors such as whether you own or rent the property, its age, previous grant support, and whether you use an SEAI-registered contractor. You normally need to receive grant approval before starting the work, and the final payment depends on meeting SEAI’s requirements. Check SEAI’s current Home Energy Grants guidance for the latest rates, or ask a registered contractor to assess your circumstances; lower-income households may also wish to check the Warmer Homes Scheme.
