Internal wall insulation, often called dry lining, may qualify for an SEAI home energy grant if the property and proposed works meet the scheme rules. You generally need to apply before any work starts, use an SEAI-registered contractor, and meet requirements relating to the home’s age, ownership or occupancy and existing energy performance. The exact grant level can depend on your circumstances and the insulation specification, and SEAI may require a pre- and post-works BER assessment. Check the current SEAI guidance and ask a registered contractor to confirm the requirements for your home.
