Since 27 August 2026, plug-in solar has been allowed on the Isle of Man. There is one big difference from the UK, though: here you must apply to Manx Utilities and wait for approval before you plug a kit in.
What Manx Utilities allows
- One kit per home, with a total output of 800W or less.
- Compliant kits only. The kit must be marked Compliant on the ENA Connect Direct register.
- A smart meter. If you don’t have one yet, MU says it will contact you to arrange fitting.
- Straight into a suitable socket. No extension leads or adapters.
- Applying is free. There is currently no charge.
What it does not allow
Standalone batteries are ruled out. A battery is only allowed as part of a compliant integrated kit. Spare power sent to the grid earns nothing either, because plug-in kits can’t use the Sustainable Generation tariff. Your saving comes from the power you use at home as it is made.
What to do next
Check the rules, choose a kit that is marked Compliant, then apply with MU’s Electricity Network Enquiry form. Our guides walk through each step: the island rules in full and how to get Manx Utilities approval.
