Commercial Solar Planning Permission Northern Ireland

Planning checks for rooftop and ground-mounted business solar.

Why this matters for Northern Ireland businesses

Commercial solar decisions should begin with measured energy consumption, building suitability and the purpose of the project. Project risks and opportunities differ between sites, and the correct design cannot be established from roof area alone.

What to check

Confirm the requirements for the particular site and mounting arrangement with the relevant NI authority.

Ask prospective designers to explain their inputs, design assumptions, equipment specification, responsibilities, exclusions, maintenance arrangements and completion documentation. Compare proposals on a common scope of work.

Questions to ask before proceeding

• Which site survey and load data have been used?
• What are the building and electrical constraints?
• What are the estimated generation and usage assumptions?
• What work is included or excluded from the price?
• Who is responsible for permissions, commissioning and warranties?
