Ireland Commercial Industrial Solar Planning Exemption Class 56 Guide: S.I. No. 493 of 2022

Key Takeaways

• S.I. No. 493/2022 introduced new planning exemptions for solar installations on various building types.
• Rooftop solar on industrial, commercial, apartment, educational, and healthcare buildings can be exempt under Class 56, 60, or 61.
• Agricultural buildings can benefit from exemptions under Class 18.
• Exempted installations must be primarily used for on-site electricity or heating, meaning greater than 50% consumption within the curtilage.

What are the planning exemptions for commercial and industrial solar in Ireland?

In Ireland, the Planning and Development Act 2000 (Exempted Development) (No. 3) Regulations 2022 (S.I. No. 493 of 2022) introduced significant changes to planning requirements for solar photo-voltaic and solar thermal installations. These regulations, effective as of August 2026, aim to streamline the deployment of solar energy across various sectors by granting exempted development status to certain installations. This means that if your project meets the specified criteria, you may not need to apply for planning permission.

The regulations cover several classes of buildings, expanding the scope of what qualifies as exempted development. You should review these provisions carefully to determine if your planned installation falls within their scope.

Key Statutory Provisions for Solar Exemptions (August 2026)

| Ancillary Wall Equipment Exclusion | "ancillary equipment for the purpose of rooftop solar photo-voltaic or solar thermal collector panels in classes 56(d), 56(e), 60 or 61 of Part 1 of Schedule 2 and class 18(c) of Part 3 of Schedule 2 does not include any equipment which must be placed or erected on a wall" | Provisions as of August 2026, from S.I. No. 493/2022.

What are the conditions for these solar planning exemptions?

The exemptions provided by S.I. No. 493/2022 are not unconditional. You must meet specific criteria for your solar installation to qualify as exempted development. The primary condition across most exempted classes is related to the consumption of the generated energy.

For installations under classes 56(d), 56(e), 60, 61, and 18(c), the solar photo-voltaic or solar thermal collector installation must be "primarily used for the provision of electricity or heating for use within the curtilage." The regulations define "primarily" in this context as "greater than 50%." This means that more than half of the energy generated by your solar system must be consumed on-site within the property boundary. This condition applies to industrial buildings, light industrial buildings, business premises, apartment buildings, and educational/healthcare facilities.

For free-standing solar installations, there is a specific height limitation. The regulations state that "the height of the free-standing solar photo-voltaic and/or solar thermal collector installation shall not exceed 2.5 metres at its highest point above ground level." If your free-standing system exceeds this height, it will not qualify for the exemption and will require planning permission.

What equipment is excluded from these exemptions?

While the regulations broaden the scope of exempted solar installations, they also specify certain exclusions, particularly regarding ancillary equipment. The statutory text clarifies that "ancillary equipment for the purpose of rooftop solar photo-voltaic or solar thermal collector panels in classes 56(d), 56(e), 60 or 61 of Part 1 of Schedule 2 and class 18(c) of Part 3 of Schedule 2 does not include any equipment which must be placed or erected on a wall."

This means that while the solar panels and their immediate mounting structures on the roof are covered, any associated equipment that needs to be installed on a wall, such as inverters or distribution boards, may not be exempt. You should carefully consider the placement of all components of your solar system to ensure compliance with these provisions.

How do we verify these regulations?

We verify the information presented in this guide by directly consulting the official statutory instruments published by the Irish government. For this article, we specifically referenced the "Planning and Development Act 2000 (Exempted Development) (No. 3) Regulations 2022," which is S.I. No. 493/2022. We accessed the official text from the Irish Statute Book on August 23, 2026, to ensure accuracy and currency of the legal provisions. Our aim is to provide you with precise, evidence-based information directly from the primary source.
