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:

1. Built and occupied before 1 January 2021.
SEAI verifies this through your MPRN (Meter Point Reference Number) connection date, which is held by ESB Networks. Your MPRN is on your electricity bill. If your property was first connected to the grid on or after 1 January 2021, it does not qualify. New builds get a separate route to solar under Part L building regulations — the SEAI grant is for existing homes only.

2. A BER must exist on the property.
There is no minimum BER rating — the old B2 minimum was removed in 2022. You need a BER to exist on file, and you will need to commission a post-works BER after installation 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 cannot apply for this grant on your behalf. 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 first connection date predates 1 January 2021. You can also call ESB Networks on 1850 372 757 and ask for your connection date if it is not clear from your bill. If your home passes this check, note your MPRN — your installer 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. If no BER exists, your installer may arrange the post-works BER directly. The pre-works BER is not a prerequisite for applying, but a BER must exist on the property (pre- or post-works) at the point the Declaration of Works is submitted.

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 free quotes 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. Your installer has an account on this portal and submits on your behalf.

To complete the application, your installer will need from you:

• Your full name and home address
• Your MPRN
• The proposed system size in kWp
• Your bank account details (IBAN) — SEAI pays the grant directly to your account after installation, not to the installer

You will sign a homeowner authorisation/declaration form confirming the application details. Keep a copy.

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 locked in for your system size 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).

The Letter of Offer comes to your installer. 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: Installer submits the NC6 notification to ESB Networks

After installation, your installer submits an NC6 notification form to ESB Networks. This notifies the grid operator that a new microgenerator has been connected to the network 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. Processing by ESB Networks typically takes 2–6 weeks; once complete, contact your electricity supplier to register for microgeneration export payments.

Step 7: Declaration of Works submitted to SEAI

After installation, your installer compiles and submits the Declaration of Works to the SEAI portal. 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
• A signed homeowner declaration (you countersign the document confirming the work is completed to your satisfaction)
• The post-works BER certificate (completed by a registered SEAI BER Assessor — this must be done before submission)
• 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). The grant is paid to you, not to your installer. Your installer’s invoice is the gross amount; the SEAI payment reimburses you the grant portion 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.

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
Homeowner authorisation declaration	You (signed)	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; installer submits 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	Same week as 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: the SEAI grant is not deducted from your installer’s invoice upfront. Your installer cannot legally reduce their invoice by the grant amount and assume SEAI will reimburse them.

How it actually works:

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. The grant is always paid to you, never to the installer. If any installer suggests they can “apply the grant at the point of sale” and reduce your invoice directly, ask for clarification — the current SEAI scheme does not work this way.

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 qualify an electrician to submit SEAI solar grant applications. 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 property’s MPRN connection date is on or after 1 January 2021. This cannot be appealed either. Verify the date 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.
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 until end of 2028 (revenue.ie). 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 cannot start until you have a contract with an SEAI-registered installer. 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 and price is what your installer needs to submit a complete application.
