How to Apply for the SEAI Solar Grant in 2026: A Step-by-Step Guide

The SEAI Solar Electricity Grant pays up to €1,800 toward a residential solar PV installation in Ireland. Applying for it is an eight-step process that starts before your installer sets foot on the roof. This guide walks through each step in the order you will actually do it, including the documents you need, the timeline to expect, and the two points where a mistake causes the grant to be forfeited entirely. Full grant details are in our SEAI solar grant overview.

Who Is Eligible for the SEAI Solar Grant?

Before you contact any installer, do this 60-second eligibility check. Your home must meet all four conditions, set out in full in our guide to SEAI solar grant eligibility in Ireland:

1. Built and occupied before 1 January 2025.
SEAI asks for the year the home was built and occupied; if you're unsure, ESB Networks can tell you the year it was first connected. You'll also need your MPRN (Meter Point Reference Number), which is on your electricity bill. Since 6 October 2026 the cut-off is before 2025 (it used to be before 2021). A home built or first occupied in 2025 or later does not qualify.

2. A post-works BER is required.
There is no minimum BER rating — the old B2 minimum was removed in 2022 — and you don't need a BER to apply. What SEAI requires is a post-works BER, commissioned after installation and published before the grant is paid. The post-works BER is completed by a registered SEAI BER Assessor and costs roughly €150–€250.

3. Installation by an SEAI-registered installer.
This is the single most common reason grants are forfeited. An electrician who holds a Safe Electric or RECI cert but is not on the SEAI’s separate Renewable Installer list does not qualify you for this grant. Verify any installer on the SEAI registered installer list before signing a contract.

4. Located in the Republic of Ireland.
The scheme covers all 26 counties. Northern Ireland has a separate scheme; the SEAI grant does not apply there.

Renters: the grant is paid to the homeowner who commissions the work. Renters cannot apply directly; landlords can apply for properties they own.
Commercial properties: not eligible under this residential scheme.

The Eight-Step SEAI Solar Grant Application Process

The process runs in a strict order. Steps 1–4 happen before installation. Steps 5–8 happen after. Doing anything out of sequence — especially starting the install before receiving the Letter of Offer — forfeits the grant.

Step 1: Confirm your home is eligible

Locate your MPRN on your electricity bill and check that the home was built and occupied before 2025. If you are unsure of the year, call ESB Networks on 1800 372 757 and ask when the property was first connected. Note your MPRN — you will need it for the grant application.

Check also whether a BER exists for your property. You can search the SEAI BER register by address for free. Either way, you don't need a BER to apply. What SEAI requires is a post-works BER, carried out after the installation and published before the grant is paid; an older BER on the register does not count.

Step 2: Get quotes from SEAI-registered installers

Get at least two or three quotes. This is not just about price: getting multiple quotes means you see a range of system size recommendations, panel brands, and inverter types, which often differs more than the headline price.

A properly itemised quote should show:

• Panel brand, wattage per panel, and total panel count
• Inverter brand and model
• Mounting and cabling
• Scaffolding (if required)
• NC6 grid connection notification to ESB Networks
• Post-works BER assessment (some installers include this; some quote it separately)
• SEAI grant application handling
• Gross price and net price after the SEAI grant deduction, clearly shown

Every installer in the Solar Quotes Ireland network is verified as SEAI-registered before being listed. Request a quote here.

Step 3: Apply for a Letter of Offer via the SEAI portal

Once you have signed a contract with your chosen installer, the grant application is submitted via mgen.seai.ie — SEAI’s online portal for the Microgeneration Support Scheme and individual grants. You apply as the homeowner and name the SEAI-registered company you have chosen; many installers will walk you through it.

To complete the application you will need:

• Your full name and home address
• Your MPRN
• The proposed system size in kWp
• The year the house was built and the name of your SEAI-registered company
• Bank account details (IBAN) for the grant — SEAI accepts either your own account or the solar PV company’s

Keep a copy of what you submit.

Step 4: Accept the Letter of Offer

SEAI processes the application and issues a Letter of Offer, typically within 2–4 weeks of submission. The Letter of Offer confirms the grant amount for your system size (you get the amount in force on the day you applied) and sets a validity window — currently 8 months from the date of the offer letter (verify against your specific letter, as windows have changed historically).

SEAI emails the Letter of Offer to you. Check that the company named on it is the one doing the work, and review it before work begins: it should confirm the system size in kWp, the grant amount, and the submission deadline for the Declaration of Works.

Installation cannot begin until the Letter of Offer has been issued and accepted. This is the rule most commonly overlooked. If you or your installer proceeds with installation before receiving the offer letter — even by one day — the grant is forfeit, with no appeal route.

Step 5: Installation is carried out

Your installer schedules the install. A standard residential solar PV installation takes 1–3 days on-site. On completion, you receive:

• A system commissioning certificate
• A RECI (Registered Electrical Contractor Ireland) electrical safety certificate
• Panel and inverter warranties (typically 25 years for panels, 10 years for inverter)
• A wiring diagram and system handover pack
• Access credentials for the monitoring app (most inverters come with an app showing live output)

Step 6: The NC6 notification to ESB Networks (sent before the install)

Your installer submits an NC6 notification form to ESB Networks. SEAI says this must be done before the system is installed and usually takes at least 4 weeks (20 working days), so in practice it happens alongside Steps 4 and 5. It tells the grid operator that a microgenerator is being connected at your address. The NC6 is a mandatory step under the Microgeneration Support Scheme (CRU framework) and is required before your electricity supplier can set up Clean Export Guarantee (CEG) payments for any surplus electricity you export.

The NC6 is submitted by your installer, not by you. You do not need to contact ESB Networks directly. Your installer will confirm when this has been done. Once the system is connected, contact your electricity supplier to register for microgeneration export payments.

Step 7: Declaration of Works submitted to SEAI

After installation, your solar PV company uploads the Declaration of Works and supporting documents to SEAI. This is the document package that triggers the grant payment. It must be submitted within the validity window stated in the Letter of Offer (currently 8 months).

The Declaration of Works submission includes:

• The completed and signed Declaration of Works form
• Your countersignature on the Declaration of Works, where the form asks for it
• The inspection, test and commissioning certificate
• The completed ESB Networks NC6 form
• The post-works BER (your BER Assessor publishes it on the National BER Register — it must be there before SEAI pays)
• Installation photographs
• The installer’s invoice for the works
• The RECI electrical safety certificate

The post-works BER assessment is the step that often causes delay here. Book it as soon as the install date is confirmed — BER assessors in high-demand periods (spring and early summer) can be 2–3 weeks out. Your installer may coordinate this on your behalf, or you may need to find a registered BER assessor independently via the SEAI BER register.

Step 8: SEAI pays the grant into your bank account

Once SEAI has received and accepted the Declaration of Works, they process the payment and transfer the grant directly into your bank account (the IBAN you provided at Step 3). SEAI allows that account to be yours or the solar PV company’s. If it is yours, your installer’s invoice is the gross amount and the SEAI payment reimburses you separately.

SEAI aims to process payment promptly after the Declaration of Works is accepted (seai.ie — Solar Electricity Grant). Allow 4–8 weeks from submission as a working estimate; if documents are missing or SEAI has queries, they will contact your installer and the review period extends. Submitting a complete Declaration of Works the first time is the most effective way to avoid delays.

One extra step can sit between the Declaration of Works and the money. SEAI inspects a sample of grant-aided homes, and the visit can come either before payment or after it, so a payment can be held while an inspection is arranged. Our guide to the SEAI grant inspection covers the notice you get, what the inspector checks, and the access requirement that cancels a grant outright if it is missed.

What Documents Do You Need?

Most of the paperwork is handled by your installer. Your direct contributions to the document set are:

Document	Who provides it	When needed
MPRN	You (from your electricity bill)	Step 3 — grant application
Bank IBAN	You	Step 3 — grant application
Online grant application	You	Step 3 — grant application
Homeowner countersignature on Declaration of Works	You (signed)	Step 7 — Declaration of Works
Post-works BER certificate	Registered SEAI BER Assessor	Step 7 — Declaration of Works
RECI electrical safety certificate	Your installer	Step 7 — Declaration of Works
Installation invoice	Your installer	Step 7 — Declaration of Works
Installation photographs	Your installer	Step 7 — Declaration of Works

How Long Does the SEAI Grant Process Take?

The full timeline from first quote request to grant payment typically runs 8–16 weeks. The longest variable is your installer’s available start date: SEAI-registered installers in most counties are currently booking 3–6 months ahead due to the 65% year-on-year increase in applications in Q1 2026 (gov.ie, April 2026).

Stage	Typical duration
Get and compare 3 installer quotes	1–2 weeks
Sign contract; you submit grant application	Same week
SEAI issues Letter of Offer	2–4 weeks
Install scheduled and completed	2–6 weeks after Letter of Offer
NC6 submitted to ESB Networks	At least 4 weeks before install
Post-works BER assessment	1–2 weeks after install
Declaration of Works submitted	Same week as BER
SEAI reviews and pays grant	Allow 4–8 weeks after Declaration of Works
Total: quote request to grant payment	8–16 weeks

If your installer is heavily booked, the install date alone can push the overall timeline to 5–6 months from first enquiry. Starting the quote process early in the year is the most effective way to keep the timeline short and secure a summer install slot.

How the Grant Works With Your Invoice

A common source of confusion: whether the grant comes off your invoice depends on whose bank account is on the application. SEAI accepts either your account or the solar PV company’s.

How it works when the grant is paid to you:

1. Your installer issues a gross invoice for the full cost of the installation (e.g. €9,500 for a 4 kWp system).
2. You pay the installer that full amount.
3. SEAI pays the grant (€1,800) directly into your bank account after the Declaration of Works is accepted; allow 4–8 weeks from submission.
4. Your net cost is the invoice minus the grant payment (e.g. €9,500 − €1,800 = €7,700).

Some installers quote two figures: a gross price and a net-after-grant price, for clarity. Both are legitimate. If an installer offers to take the grant off the invoice, the application will carry the company’s bank details, so check what is entered in the portal and get the arrangement in writing.

The Five Reasons Grant Applications Fail

The SEAI grant has a high approval rate when the process is followed correctly. When applications fail, it is almost always one of these five reasons:

1. The installer is not on the SEAI registered list. A standard Safe Electric or RECI cert does not put a company on the SEAI solar PV register, and only a registered company can be named on your application. The SEAI runs a separate Renewable Installer registration. Always confirm via the SEAI installer list before signing.
2. Installation started before the Letter of Offer was issued. This is the second most common cause. There is no appeal. The Letter of Offer must be in hand before work begins — no exceptions.
3. The home was built or first occupied in 2025 or later. (Before 6 October 2026 the cut-off was 2021.) Check the year before getting quotes, not after.
4. The Declaration of Works was submitted after the Letter of Offer expired. Currently 8 months, but the offer letter states the specific deadline. If the install is delayed beyond the window, you must reapply — and may receive a lower grant if the scheme has stepped down. SEAI's support page for individual grants does describe a late-submission route using a cover letter explaining the delay, which is covered in our guide to SEAI complaints and appeals.
5. Missing or incomplete documentation in the Declaration of Works. The post-works BER is the most frequently missing item. Book the assessor before the install, not after.

Stacking the Grant With Other Incentives

The SEAI solar grant can be combined with these incentives on the same property:

0% VAT on residential solar PV — in effect since May 2023. Every residential solar quote already includes 0% VAT. This saving stacks with the grant automatically when you use an SEAI-registered installer.

Clean Export Guarantee (CEG) — not a grant, but an income stream. Once the NC6 is processed, your electricity supplier pays you per kWh for surplus electricity exported to the grid. The first €400/year of CEG income is tax-exempt for 2024 to 2028 (revenue.ie), and Budget 2027 announced a rise to €600, with the start date to be set in Finance Bill 2026. Export rates vary by supplier from approximately 15.89c/kWh to 32c/kWh year 1 (rates as of May 2026 — check your supplier’s current offer).

SEAI Heat Pump Grant — a separate application, no conflict with the solar grant. Both can be claimed on the same property (different equipment, different applications).

SEAI EV Home Charger Grant (€300) — separate application, stackable.

TAMS 3 (for farmers) — does not stack with the SEAI solar grant on the same installation. Choose one.

Your Next Step

The grant application needs a chosen SEAI-registered company and a system size. Everything else follows from that. If you are still at the research stage, the most useful next step is getting quotes — not to commit, but because a quoted system size is what you need to submit a complete application.
