Is plug-in solar legal in Northern Ireland?
No, not yet. Compliant kits can be sold in Northern Ireland, because the plug-approval part of SI 2026/848 applies across the whole UK. But the part that makes it lawful to plug a kit into a socket applies only to England, Wales and Scotland. Northern Ireland's connection rules are the Electricity Safety, Quality and Continuity Regulations (Northern Ireland) 2012 and Engineering Recommendation G98/NI, and neither has been changed. Any change is a matter for the relevant Northern Ireland department, and as at 23 September 2026 we found no announced change or date.
Can I still install rooftop solar in Northern Ireland?
Yes, through the normal route: a qualified installer connects the system, and it must be agreed with or notified to the network operator, NIE Networks. Planning is devolved to Northern Ireland's councils, so ask your local council whether permission is needed for your installation.
Is VAT charged on solar panels in Northern Ireland?
The 0% rate on the installation of energy-saving materials, including solar panels, has applied in Northern Ireland since 1 May 2023 and is scheduled to run until 31 March 2027, when the reduced 5% rate is due to return unless the relief is extended.
NIE Networks runs the electricity distribution network in Northern Ireland, separate from the Great Britain network operators. Connection requirements for small generators in Northern Ireland are set separately, under Engineering Recommendation G98/NI, rather than the Great Britain G98.
