Before you apply
Building Regulations (Part L)
Planning considerations
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
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.
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.
