Rules are changing quickly. This page reflects what we could confirm on 21 September 2026. Check GOV.UK, your network operator and a qualified installer before you buy or connect anything. General information, not legal or electrical advice.
Plug-in solar
Plug-in solar is not yet permitted for use in Northern Ireland. Compliant kits can be sold here, because the plug-approval part of SI 2026/848 applies across the 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. The Energy Saving Trust also says plug-in solar is not currently permitted for use in Northern Ireland. Do not plug a kit into a socket in Northern Ireland until the rules change. Check the Department for the Economy, NIE Networks and Consumer Council guidance for updates.
Rooftop and hardwired solar
Standard rooftop and hardwired systems remain available through qualified installers, and must be notified to the network operator, NIE Networks. Planning in Northern Ireland is devolved, so ask your local council whether permission is needed.
Export payments
The Smart Export Guarantee applies in Great Britain, not Northern Ireland. Ask your supplier what, if anything, they pay for exported power.
Renting
Check your tenancy or lease and ask the landlord in writing before fixing anything to external walls or balconies.
