You make the grant application yourself, but it has to name an SEAI-registered solar PV company, and only that company can upload the completion paperwork. A non-registered installer means no valid Letter of Offer, no Declaration of Works, no grant. The €1,800 disappears, and what looked like a cheaper quote ends up costing you over €1,000 more.
The Rule and Why It Exists
The SEAI Solar Electricity Grant requires your installer to be listed on the SEAI Registered Companies list at the time the work is carried out. This is not a recommendation — it is a hard condition of the scheme.
SEAI-registered installers agree to meet the scheme’s technical standards, use compliant products, and complete the required documentation. That registration gives SEAI a mechanism to audit installs and withdraw approval from poor performers. Without it, SEAI has no relationship with your contractor, and the grant process cannot start. There is no workaround. You cannot submit the paperwork yourself and claim the grant retroactively. The same applies if you're tempted to install the system yourself — self-installing forfeits the grant, the 0% VAT and your export payments.
The Cost Comparison That Changes the Conversation
| SEAI-Registered Installer | Non-Registered Installer | |
|---|---|---|
| Gross quoted price | €8,500 | €7,800 |
| SEAI grant available | €1,800 | €0 |
| Net cost to you | €6,700 | €7,800 |
| Difference | You pay €1,100 more with the non-registered installer | |
The non-registered quote is €700 cheaper on paper. After applying the grant, it costs you €1,100 more.
Non-registered installers — or registered installers who have let their status lapse — can price below the market because they are not carrying the administrative overhead of scheme compliance. That lower headline number is not a saving. It is the cost of losing the grant.
The same logic holds across every common system size. On a 3 kWp install, the grant is worth €1,600. A non-registered quote would need to come in €1,600 below the registered quote just to break even. On a 4 kWp install, the gap rises to €1,800. Very few non-registered quotes are priced that far below the market.
What the Registered Installer Does for the Grant
Three steps in the grant process sit entirely with your installer — you cannot do them yourself:
- The solar PV company submits the NC6 notification to ESB Networks (required for grid connection and microgeneration registration)
- The installer completes and signs the Declaration of Works, and the company uploads it to SEAI with the test certificate, Safe Electric cert, NC6 form, invoice and photos
- Your application must name your chosen SEAI-registered company at the outset, and the grant is only payable for the company named on your Letter of Offer. Changing company means cancelling and reapplying before works start
The grant is paid into the bank account you nominate, which SEAI allows to be either yours or the solar PV company’s. Either way, your installer controls the documentation that triggers that payment. Without a registered installer, the chain breaks at step one.
How to Verify Your Installer’s Registration
The SEAI Registered Companies search is public and free:
seai.ie/find-grants-and-contractors/find-contractors/solar-pv-companies
Search by company name or county. Each entry shows the company’s SEAI registration number and the counties it serves. If a company is not on the list, SEAI’s own warning is that its installations “do not qualify for SEAI grant support”.
Check on two dates:
- The day you sign the contract
- The day work starts
Registrations can change between those two dates. If an installer’s status changes mid-project, your grant may be at risk for work completed after the deregistration date.
Take a screenshot of the registration status on the day you sign. If there is ever a dispute about timing, that screenshot is your evidence.
Safe Electric (RECI) Is Not the Same as SEAI Registration
A compliant solar install in Ireland requires two separate registrations. They cover different things.
Safe Electric (RECI) — the electrical certification. Grid-connected solar PV wiring must be carried out by a Safe Electric Registered Electrical Contractor (Safe Electric is the CRU's scheme, run by Safe Energy Ireland since 2023; the Register of Electrical Contractors of Ireland, RECI, ran it until 2022, which is why many still say RECI). This is a legal requirement: under the CRU’s electrical safety regime, restricted and controlled electrical works can only be done by a registered contractor. SEAI also requires a Safe Electric certificate before it pays the grant.
SEAI registration — the scheme-administrative approval. This confirms the company can be named on an SEAI grant application and has committed to the scheme’s technical standards and code of practice.
Both are needed. An installer with Safe Electric registration but no SEAI registration can carry out a legal install — but you cannot access the grant. An installer who claims SEAI registration but cannot produce a Safe Electric cert is not legally authorised to do the electrical work.
When you ask an installer for proof of registration, ask for both. The SEAI list is at seai.ie. The Safe Electric register is at safeelectric.ie/find-an-electrician. Check both before signing anything.
When you submit your details, you receive quotes from registered companies only — so the grant is available on every quote you compare.

Both. Your installer must be on the SEAI Registered List before you submit the grant application, and they must remain on it when the work is carried out. SEAI checks registration status at the time of installation. If an installer was registered when you applied but had been removed by the time the panels went up, the grant is at risk. Check status on the day work starts, not just the day you sign.
No. The NC6 to ESB Networks is submitted by the solar PV company — you have no mechanism to do this yourself. The installer completes and signs the Declaration of Works and the company uploads the completion documents to SEAI. Without a registered company named on your application, the grant process cannot be completed regardless of what you do on the portal.
Your grant is at risk. SEAI requires an active registered company to complete the works, so registration on the day of the install is what counts, not the day you signed. If the company is no longer registered when the panels go up, its completion paperwork will not be accepted. Contact SEAI before any work starts: changing company means cancelling your application and reapplying with the new one.
No — they are separate databases run by different bodies. The SEAI Registered Companies list covers companies you can name on a grant application. The Safe Electric (RECI) register covers electrical contractors legally authorised to carry out grid-connected electrical work. Your installer must be registered with both. Not every registered contractor chooses to appear in Safe Electric’s public search, so if yours is missing, Safe Electric will confirm by email or phone. The SEAI list is at seai.ie/find-grants-and-contractors/find-contractors/solar-pv-companies. The Safe Electric register is at safeelectric.ie/find-an-electrician. Check both before signing anything.
