A non-registered installer cannot submit any of the SEAI grant paperwork. That means no 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 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 installer submits the NC6 notification to ESB Networks (required for grid connection and microgeneration registration)
- The installer signs the Declaration of Works, which you then countersign and upload to the SEAI portal
- The installer’s registration number must appear on the SEAI portal application at the outset — without it, the application cannot progress past the installer-selection step
The grant is paid directly into your bank account, not the installer’s. But 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. The result shows whether the installer is currently active, suspended, or removed.
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. All grid-connected solar PV work must be carried out by a Safe Electric Registered Electrical Contractor (Safe Electric is the consumer-facing scheme run by RECI, the Register of Electrical Contractors of Ireland). This is a legal requirement under the ETCI National Wiring Rules. Without it, the system cannot be registered with ESB Networks for microgeneration.
SEAI registration — the scheme-administrative approval. This confirms the installer is authorised to apply for SEAI grants and meets the scheme’s technical standards.
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-a-contractor. 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 installer directly — you have no mechanism to do this yourself. The Declaration of Works requires the installer to sign first. Without a registered installer, the grant process cannot be completed regardless of what you do on the portal.
Your grant is at risk. SEAI checks registration status at the time of the work, not the time you signed the contract. If the installer is no longer active when the panels are installed, the Declaration of Works cannot be submitted. Contact SEAI directly and, if possible, arrange for a new SEAI-registered installer to complete the work.
No — they are separate databases run by different bodies. The SEAI Registered Companies list covers installers approved to submit grant applications. The Safe Electric (RECI) register covers electrical contractors legally authorised to carry out grid-connected electrical work. Your installer must appear on both. 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-a-contractor. Check both before signing anything.
