FREQUENTLY ASKED QUESTIONS
What SEAI grants are available for home insulation and how much can I receive?
Homeowners can access SEAI Home Energy Grants to help cover the cost of insulation upgrades. The exact grant amount depends on the measure and property type. For example, external wall insulation grants can be up to €8,000 for a detached home, €6,000 for a semi-detached, €3,500 for a mid-terrace, and €3,000 for an apartment. Other insulation grants (attic, cavity, internal wall) have their own values based on property type.
Do I need to use a registered contractor to qualify for the SEAI grant?
Yes. To be eligible for SEAI grant funding, all energy upgrade works including insulation must be carried out by an SEAI-registered contractor. This ensures the installation meets SEAI technical standards and is inspection ready. After works are completed, you’ll also need to submit a post-works BER assessment and signed documentation to SEAI to draw down the grant.
How long do insulation works usually take?
This depends on the measure and property size:
- Attic or cavity insulation: typically, 1-2 days
- Internal wall insulation: several days, depending on scope
- External wall insulation: usually 2-4 weeks
A clear schedule is agreed in advance.
