Top Energy Upgrades for Irish Businesses?

Energy grants are available for a variety of energy-efficient upgrades, including:

Commercial Solar PV (The Non-Domestic Microgen Grant): Ireland’s most popular business grant. It supports solar installations from 6kWp up to 1,000kWp. For many businesses, this can reduce daytime electricity bills by 40% to 70%.
EV Charging & Fleet Support: Install workplace chargers at a 60% discount (up to €5,000 per point) through the ZEVI/SEAI scheme
Lighting & Heating (SSR & ACA): Switching to LED lighting and high-efficiency heating systems are the fastest ways to lower monthly costs. While direct grants vary, these are almost always eligible for the Accelerated Capital Allowance (ACA) tax benefit.

Key Grant Programmes for Businesses

Maximise Your ROI with Accelerated Capital Allowance (ACA

The ACA is a tax incentive that allows companies, sole traders, and farmers to deduct the 100% of the cost of qualifying energy-efficient equipment from their taxable profits in the very same year of purchase.

While standard equipment is typically depreciated over 8 years (12.5% per year), the ACA provides an immediate cash-flow boost. When you combine the ACA with an SEAI grant, the effective cost of your solar or energy upgrade can drop by over 50%, often leading to a payback period of just 3 to 5 years.

Non-Domestic Microgen Grant (Solar PV)

This is the flagship scheme for businesses, farms, and schools. It provides tiered funding for solar panel installations ranging from €900 up to €162,600. Whether you are a small shop looking for a 6kWp system or a large factory installing 1,000kWp, this grant dramatically lowers your upfront capital cost.

Frequently Asked Questions

Are there electric vehicle grants for businesses?

Yes. While EV grants for commercial vehicles are limited and vary year to year, businesses can apply for support with EV charger installation through SEAI and Zero Emission Vehicles Ireland (ZEVI). The Accelerated Capital Allowance (ACA) also provides tax relief for EVs and charging infrastructure.

Does my business need to be a certain size to apply?

No. Both SMEs and large enterprises can apply, though some grants are tailored to specific business types or energy spend levels.

Can I apply for a grant if I already started the work?

No. You must apply and be approved before starting any work to qualify for SEAI grants.

I’m not sure which energy upgrade is right for my business—where should I start?

A great starting point for any Irish business is the SEAI Support Scheme for Energy Audits (SSEA). SEAI offers a €2,000 voucher to SMEs to cover the cost of a professional energy audit. This audit provides you with a tailored roadmap of the most effective energy-saving measures for your specific building and helps you identify which capital grants (like Solar PV or SSRH) you should apply for next.

Do I need to use an SEAI-registered contractor?

For most grant schemes, yes — you’ll need to work with SEAI-approved suppliers and installers to be eligible for funding. Check the SEAI site for registered lists.

I work from home — should I apply for a business grant or a home energy grant?

In most cases, you should apply for a home energy grant, not a business grant.
That’s because SEAI’s Business Energy Grants are intended for commercial premises, not residential properties — even if business is conducted there. If you work from home (e.g. remote employee, freelancer, or sole trader), and the energy upgrades benefit your entire home or attached home office, then you qualify under the Home Energy Grant scheme.
Key points:
Apply under the Home Energy Grant scheme if your workspace is part of your house.
Business grants typically don’t apply to residential addresses.
You may still be able to claim business expenses separately through Revenue, such as electricity or heating related to your office use — but this is a tax matter, not related to SEAI grants.
Always check with SEAI or a registered contractor if you’re unsure which path applies to your situation.

What is the Non-Domestic Microgen Grant and who is it for?

The Non-Domestic Microgen Grant provides financial support to businesses, farms, and community organizations for installing solar PV panels. It currently offers a maximum grant of €162,600 for large-scale installations (up to 1,000kWp), making it a massive incentive for Irish enterprises looking to slash overheads

Can my business claim the Accelerated Capital Allowance (ACA) alongside a grant?

Yes! The ACA scheme allows companies and sole traders to deduct the full cost of qualifying energy-efficient equipment (including solar panels and EVs) from their taxable profits in the same year of purchase. This can be used in conjunction with SEAI grants, significantly accelerating the return on investment.

Are there grants available for heating systems other than Solar PV?

Yes. The Support Scheme for Renewable Heat (SSRH) provides significant financial support for businesses switching to renewable heating. This includes investment grants of up to 40% for air, ground, or water source heat pumps, and an ongoing operational tariff (paid for up to 15 years) for businesses using biomass or biogas heating systems

Do I need planning permission for commercial solar panels in Ireland?

In most cases, no. Since 2022, planning exemptions have been greatly expanded. Most businesses can now install solar panels on their roofs (and even some ground-mounted systems) without planning permission, provided they meet certain criteria regarding height and proximity to airports or “solar safeguarding zones.

Are there grants for business electric vehicles (EVs)?

Yes. Businesses can claim up to €3,800 for small vans and €7,600 for large panel vans through SEAI. There are also significant tax benefits like the Accelerated Capital Allowance (ACA)

Can I get a grant for installing EV chargers at my workplace?

The Workplace Charging Grant covers up to 60% of installation costs, capped at €5,000 per charger. This is available for SMEs and large enterprises to support staff and fleet charging.

What is the BIK rate for electric company cars?

Electric company cars currently benefit from a €0 BIK liability on the first €35,000–€45,000 of the car’s value (depending on the year). This makes EVs an incredibly tax-efficient perk for Irish employees.
