Step by step
- Check where you stand. The Ready check, your BER Advisory Report or a pre-works BER.
- Get quotes from SEAI-registered contractors for the insulation and the windows.
- Apply once for every grant you need. Nothing is ordered or started before the offer.
- Accept the offer within 30 days.
- Insulate: the attic, then the walls.
- Fit the windows and doors. With solid walls and external insulation, plan the windows with the wrap.
- Post-works BER, with a €50 grant towards it. It has to show a Good or Very Good heat loss figure.
- Claim within 8 months of the offer. SEAI usually pays in 4 to 6 weeks.
Is your home ready for the windows grant?
Four quick taps. You see where your home stands, what has to come first and every grant on the way. Your number is only asked for at the end, if you want a price.
A semi-D with the attic done and cavity walls never filled: 1 step first, the €1,300 cavity grant, then €3,000 for the windows and up to €1,600 for two doors.
How this is worked out
SEAI's windows and doors grant needs a Good or Very Good Heat Loss Indicator on the BER Advisory Report after the work, which SEAI says an HLI below 2.3 meets. Attic and wall insulation rated Good or Very Good on your report means you meet the standard. The grants are SEAI's fixed amounts for your home type, and the doors grant is shown for two doors. The check is a guide: a BER assessor and SEAI decide.
What goes wrong
- Windows first, insulation never. The home fails the heat loss test after the work.
- Work started before the offer. Grants can't be backdated.
- The deadline. Leave time inside the months for the BER and the forms.
