Can I apply for several SEAI grants at once?
Yes. One application can carry several measures, for example attic, walls and windows together.
SEAI’s rule, in its own words
You can choose several measures in one application.
“You can select multiple measures e.g. attic, wall, heating controls when applying.” SEAI: Individual grants: Homeowner Application Guide, read 25 Sept 2026
Each application needs a BER afterwards.
“All grant applicants must carry out a post-works BER assessment” SEAI: Attic insulation grant, read 13 Jul 2026
Grouping the insulation and the windows in one application also keeps the windows grant safe.
