Who can apply

All homeowners, including landlords, whose homes were built and occupied before 2006 can apply. This is defined as the date your electricity meter was installed.

Grant funding can only be issued once per property for each type of works. This means that any property which previously availed of wall insulation via the Better Energy Homes scheme, or any other government scheme, cannot receive additional support for further wall insulation works

Homes built from 2006 onwards should have been constructed to the 2003 Building Regulations and should not need significant upgrades.

Before you apply

Building Regulations (Part L)

Part L of the Building Regulations require that after any alteration to a minimum of 25% of your home’s surface area, either:

  • your home achieves a minimum B2 BER rating
  • your heating system and attic insulation comply with the Building Regulation standards

If you are applying for an SEAI grant for External or Internal Wall Insulation you are required to comply with these Building Regulations as a condition of your grant payment.

Planning considerations

In some cases external insulation may require planning permission. For example with protected structures, in architectural conservation areas or where the works result in an alteration to the front profile of the property. Please check with your registered contractor or local planning authority.

Planning permission is not required for internal or cavity insulation.
