Most people who lose an SEAI grant do so for avoidable reasons: work started too early, the contractor wasn’t registered for that measure, or the paperwork arrived incomplete. This guide walks through the individual grant process from the first check to the money arriving, with a worked timeline and cash-flow example so you can plan around it.
First, pick the route
SEAI supports homeowners in three different ways, and the application process is different for each:
| Route | Who manages it | How the grant is paid | Best for |
|---|---|---|---|
| Individual grants | You apply and hire the contractor | Paid to you after the works | One measure at a time |
| One Stop Shop | A registered provider manages a whole-home retrofit | Deducted from the price | Several measures in one project |
| Warmer Homes Scheme | SEAI arranges the works | Free for eligible households | People on qualifying payments |
This guide covers individual grants. For the other two see One Stop Shop vs individual grants and the Warmer Homes Scheme.
What to have ready before you apply
- Your MPRN — the 11-digit meter point reference number printed on your electricity bill.
- The home’s age — eligibility depends on when the home was built and first occupied. Insulation and most measures generally need a home built and occupied before 2011; heat pumps and solar PV before 2021. Check the current rule for your measure on SEAI’s page.
- A written quote from an SEAI-registered contractor for that specific measure. You don’t always need it to apply, but it tells you exactly what you are applying for and avoids surprises later.
- For a heat pump, the result of a technical assessment if your home was built before 2007 — see the heat pump grant guide.
- A budget for the post-works BER where one is required (typically €150–€350) — see BER assessment cost.
Step by step, with the pitfall at each stage
| Step | What you do | Pitfall to avoid |
|---|---|---|
| 1. Check eligibility | Read the grant conditions for your measure and house type | Assuming a grant amount without checking the current SEAI figure |
| 2. Get a quote | Ask an SEAI-registered contractor to quote the same scope you’ll apply for | A contractor who is registered, but not for this measure |
| 3. Apply online | Submit the application with your MPRN and home details | Typos in the MPRN or address that hold up the offer |
| 4. Receive the offer | Read the conditions and deadlines in the offer | Booking the contractor before this arrives |
| 5. Accept and book | Accept the offer (within 30 days for heat pumps) and schedule the works | Missing the acceptance window |
| 6. Complete the works | Works done by the registered contractor within the completion window | Changing the scope without checking it still qualifies |
| 7. Post-works BER | Book a registered BER assessor if your grant requires it | Leaving the BER until the deadline is close |
| 8. Submit and get paid | Submit the completion paperwork; SEAI pays the grant to you | Missing invoices or contractor documents |
A worked timeline
The dates below are a hypothetical example for an attic insulation job, to show the order of events and where waiting happens. Processing times vary with demand, so treat the gaps as placeholders, not promises.
| When | Event |
|---|---|
| Week 0 | Two written quotes received; application submitted online |
| Approval (time varies) | Grant offer arrives. Only now is the contractor booked |
| A few weeks after approval | Works completed in one or two days |
| Shortly after the works | Post-works BER assessment carried out, if required |
| After paperwork is complete | Claim submitted; SEAI checks it and pays the grant |
The completion window — typically about 8 months from approval for most individual grants — is generous for a single measure. It gets tight when one job depends on another: for example, insulation that must be finished before a heat pump can meet the heat-loss rule.
Plan the cash flow
With individual grants you pay first and are reimbursed later. Using purely illustrative figures:
- Contractor’s quote: €2,600
- Grant offered for your house type: €1,500
- You pay the contractor: €2,600
- Later, SEAI pays you: €1,500
- Your net cost: €1,100 — but you need the full €2,600 available until the grant arrives.
If that gap is a problem, ask the contractor about staged payments before you accept the offer, or compare the One Stop Shop, where the grant comes off the price.
Paperwork checklist for the claim
Keep everything in one folder (paper or digital) from the start:
- The grant offer and your acceptance
- The contractor’s final invoice, showing the measure and address
- The contractor’s completion documentation required by SEAI
- The BER certificate if a post-works BER is required
- Photos of the works before they are covered up (useful if questions arise)
- Your bank details for the payment
The mistakes that cause delays or lost grants
- Starting before approval — even partially.
- Using a contractor who isn’t registered for that measure.
- Changing the job (for example, a different product or area) without checking it still matches the grant.
- Missing deadlines — the 30-day acceptance for heat pumps, or the completion window.
- Leaving the BER until last, so the claim waits on the assessor’s diary.
- Doing things in the wrong order — a heat pump before the insulation it needs.
