A socket outside, done properly
IP55 or better, checked before we fit.
Read moreWho yours is
National Grid Electricity Distribution (West Midlands) plc runs the wires under Birmingham, Coventry, Wolverhampton and the Black Country, one of fourteen distribution licence areas across Great Britain. Ours is a working answer rather than a certainty, so the postcode gets a second check against the operator's own tool before anything leaves us.
A phone call skips the checking altogether. Dial 105 from a landline or mobile anywhere in England, Scotland or Wales and the call routes itself to whichever firm owns the cables at that address, no postcode lookup needed on our part or yours.
An older name you might see
Older paperwork sometimes still names Western Power Distribution. The company took its current name, National Grid Electricity Distribution, in 2022, and the network behind it has not changed.
What the form asks for
The government's own impact assessment describes it as a short online form, five to ten minutes, completed within 28 days of the panel going in, asking for a name, an email address and the address it was installed at.
We treat that as the process the guidance describes rather than a deadline with a penalty attached, since that is how the assessment itself frames it. We go through it with you on the visit rather than leaving it for later.
Why it is one per household
Left to the product rules alone, a house could carry one device per final ring circuit and more than one overall. The network side closes that gap: Engineering Recommendation G98 Issue 2 Amendment 1, put forward by the Energy Networks Association in April 2026 and signed off by Ofgem that August, holds every household to a single device.
What registering gets you
It is not only a condition of the framework. Where an export tariff is on offer, getting paid for it depends on the device being registered with the operator first, so there is a reason to do it beyond the rule itself.
Questions about the form
Does the operator approve it before it goes in?
No. The framework treats registration as something that happens after fitting, not an application beforehand. That is different from how a full rooftop system works.
What if I move house?
What is registered is the installation address, not the person. Taking the device with you means registering it again at the new address.
Does Wales or Scotland use the same operator?
No, and this site only covers Birmingham, Coventry, Wolverhampton and the Black Country, all inside England. If your postcode is over the border, say so on the form and we will point you to the right information rather than guess.
