Start by working out which grants suit your home and what they are worth. Our free calculator shows the exact 2026 amounts for your dwelling type in about ten seconds, with no email wall.
You can claim individual grants one at a time, or use a One Stop Shop provider that manages a whole-home upgrade and applies the grants for you. Single measure, individual grant. Several measures at once, a One Stop Shop is usually simpler.
For individual grants you apply to SEAI for approval before the work begins. Work started before approval is not eligible. A One Stop Shop provider handles this application on your behalf.
The work must be carried out by a contractor on SEAI's register. Every installer in our directory is registered. Get a couple of quotes before you commit.
For most grants a Building Energy Rating assessment is carried out after the work to confirm the upgrade. Solar PV is the main exception and does not need one.
With an individual grant, you submit the paperwork after completion and SEAI pays you. With a One Stop Shop, the grant is deducted from your bill so you only pay the balance.
Check your exact 2026 grant amounts, then get matched with vetted, SEAI-registered installers in your county.
Before. You must have grant approval from SEAI in place before the work starts. A One Stop Shop provider manages this step for you.
Approval is typically issued within a few weeks, and you then have a set window (currently eight months for individual grants) to complete the work. Confirm current timelines on SEAI's website.
Yes. Many homeowners combine measures such as attic insulation, wall insulation and a heat pump. A One Stop Shop can coordinate several grants in a single project.
