SEAI Battery Storage Grant in Ireland
Since 6 October 2026, SEAI has offered a flat €600 grant towards a home battery of 5kWh or larger. Here is who qualifies, how it works alongside the Solar PV grant, what your installer has to do, and what to weigh up before adding a battery.
The grant at a glance
The Battery Energy Storage System Grant is an individual SEAI home energy grant. It is a flat rate payment, so it does not increase with a larger battery, and it is separate from the Solar PV grant of up to €1,800.
| What to check | Current SEAI position |
|---|---|
| Grant amount | €600 flat rate |
| Battery size | 5kWh or larger; smaller batteries are not eligible |
| Property | Built and occupied before 2025, with an MPRN |
| Previous funding | Not available where a battery has already been grant funded at that MPRN |
| Timing | Grant offer from SEAI must be in place before installation begins |
| Installer | An SEAI registered Solar PV contractor, installing to SEAI's technical standards |
| Available from | 6 October 2026 |
Who can apply
SEAI lists homeowners, private landlords, owner management companies and Approved Housing Bodies as eligible applicant types. The home must have been built and occupied before 2025, which is the same date that now applies to the Solar PV grant.
Households that qualify for SEAI's fully funded Warmer Homes Scheme should check that route first: since 6 October 2026, solar PV and a battery are offered as standard under that scheme, so a separate individual grant application may not be needed.
Applying with solar PV, or on its own
You do not have to install solar panels and a battery at the same time to receive both grants.
- New solar PV and a battery together. You can apply for both measures in a single application, subject to each meeting its own conditions. The Solar PV grant is still calculated by system size, up to €1,800, and the battery grant adds a flat €600.
- An existing solar PV application. SEAI says you do not need to amend it. Submit a new application for the battery grant through the SEAI portal instead.
- Solar panels already installed. You can apply for the battery separately, provided the battery and your home meet the conditions and no battery has been funded at that MPRN before.
If you do not have, and are not planning, solar panels, confirm with SEAI whether a battery on its own qualifies before relying on the grant, since the scheme is designed around solar PV homes.
As with other individual SEAI grants, the battery must not be installed until SEAI has issued your grant offer. A battery fitted before the offer issues is unlikely to qualify, even if it otherwise meets every condition. Plan the order as: quotation, application, grant offer, installation, then claim.
What your installer needs to do
The battery must be installed by a company registered with SEAI for domestic Solar PV, working to SEAI's Domestic Technical Standards and Specifications and the Solar PV Code of Practice. In practice, ask the installer to confirm:
- that they are currently registered with SEAI for Solar PV, not just for another measure;
- that the battery model they propose is 5kWh or larger and meets SEAI's technical requirements;
- where the battery will be mounted, since SEAI's standards set out fire safety requirements for the enclosure, the surface it is fixed to and the clearance from combustible materials;
- that the battery will be included in the ESB Networks microgeneration notification;
- which documents they will provide for your grant claim, and whether a post works BER is needed for your application, as it is for the Solar PV grant.
Our directory lists a selection of SEAI registered solar PV companies by county, so you can compare more than one quotation.
Practical points before adding a battery
€600 is a contribution, not the full cost. Our Solar Cost and Payback Calculator uses an indicative range of roughly €1,700 to €4,000 for adding a battery of around 5kWh to a new installation, before grant, so most of the cost still falls on the household. A few points decide whether the rest is worth it:
- How much you export. A battery helps most where a household is out during the day and would otherwise export much of its solar generation. If you already use most of it as it is generated, a battery has less to do.
- Your tariff. On a time of use tariff, a battery can also charge from the grid at a cheaper overnight rate and discharge at the evening peak, which can add value in winter when solar output is low.
- Capacity on quotations. When comparing quotations, ask each installer for the battery's capacity and specification sheet, so you can compare like with like and check it is 5kWh or larger.
- Warranty. Check both the warranty term in years and the cycle or throughput limit, and what capacity is guaranteed at the end of it.
- Backup power. A standard battery does not keep the lights on during a power cut unless the system is specifically designed and configured for backup.
Our guide to choosing the right battery size covers usable capacity, power ratings and warranties in more detail, and our article on solar panels during a power cut explains what backup would need.
