We tell you whether the rules cover the wall, roof or ground you have in mind.

Nine licence areas, six companies. Once the panel is in, yours needs a short form within 28 days, and we sort out which.
The operator is not your electricity supplier. It is the company that owns the wires into your street, and it is fixed by where you live rather than by who you pay.
Northern Powergrid (Northeast) plc. Tyne and Wear, County Durham, Northumberland and Teesside. A south facing roof pitch near Newcastle models at 734 kWh a year, a south facing wall at 558 kWh, and a frame on open ground at 727 kWh.

Two of these are worth reading twice. The North West is split, so a Liverpool reader and a Manchester reader tell different companies. The South East is divided between two operators as well, and there is nothing on the ground that tells you where the line runs.

Two houses on the same road can sit in different licence areas near a boundary, which is why we confirm the operator by postcode rather than by region.
Our map of licence areas is a working one and we have not checked it postcode by postcode, so treat it as a starting point. Confirm it on your operator’s own postcode checker.
There is also a route that needs no map at all. Call 105, free, from anywhere in England and you are put through to the network operator for your address.
Registering the device with the network operator is a short online form. It asks for your name, your email address and the installation address, and it goes in within 28 days of the device being installed. Government guidance puts the job at five to ten minutes.
The same rules cap you at one device per household. That comes from the network connection requirements rather than from the product specification, which on its own would allow one per final ring circuit.
No. Your supplier sells you the electricity. The network operator owns the cables that bring it to the house, and it is the one that wants the notification.
Check the postcode on the operator’s own checker, or call 105 free and you will be put through to the right company for your address.
The guidance asks you to complete the short form within 28 days of installation. We fill it in with you so it does not get forgotten.
Give us the postcode and the material the surface is made from. We will tell you where that leaves you.
