Which matters, because the notification you owe after installing goes to whoever owns the wires in your street, not to your energy supplier.
Scottish Hydro-Electric Power Distribution plc
Covers the north of the country, the Highlands and the islands. A large area with a thin network, and the part of the UK where generation figures are lowest.
SP Distribution plc
The central belt and the south, so most of the population. The same company's sister licence, SP Manweb, covers North Wales, Merseyside and Cheshire, which confuses people.
One form, and it comes after the event rather than before it. A Scottish household registers the same way as any other in Great Britain: who you are, an email address, and where the device sits, inside four weeks of switching it on. Five to ten minutes at a keyboard is the figure in the impact assessment.
There is no fee and no inspection follows.
One plug-in solar device per household is the connection rule, and it applies in Scotland exactly as it does south of the border. Doubling up is not on offer.
Our licence area map is provisional. Run the postcode through whichever operator you think covers you, and let their answer settle it.
Not sure which side of the line you are on? Send the postcode.
Most of what is written about plug-in solar in the UK describes English rules. Send us a postcode and we will tell you which of the two Scottish operators covers it, what the device would make there, and which permitted development class applies to what you have in mind.
