Frequently asked questions
Is this an official SEAI calculator?＋
No. HomeUpgrade.ie is independent and not operated by SEAI. The calculator summarises public SEAI grant rules and gives indicative guidance only.
Can I start work before applying?＋
No. For most individual SEAI grants you should apply and receive written approval before any work starts or materials are ordered.
Do I need my BER rating to use it?＋
No. You can choose “I don’t know” and still get an indicative result. A BER assessment or technical assessment may still be needed before grant approval.
Will this confirm my final grant amount?＋
No. It is an estimate based on your answers. SEAI confirms final eligibility, grant amounts and payment conditions after a BER assessment and formal application.
