Checking your surface and the rules
Whether the rules cover the spot you have in mind.
Read this oneWho you tell
Your network operator is the company that owns the cables and the substations in your street. It is not your electricity supplier and you do not choose it. On our working map the operator for the West Midlands licence area is National Grid Electricity Distribution (West Midlands) plc.
That map came from a general reference rather than from the operator, so we mark it as provisional and we do not treat it as settled for your postcode.
How to confirm it yourself
Two ways. Type your postcode into the checker on the operator’s own website, or dial 105. That number is free, it reaches the distribution network operator holding your address, and it is right for every postcode in England, Scotland and Wales.
We will do this with you rather than leave you to it.
What the notification asks for
You have 28 days from installing the device to complete the operator’s online form. It wants a name, an email address, and the address the device went in at. Government’s own assessment of the scheme reckons on five to ten minutes.
This is Great Britain only. Northern Ireland is outside the GB network and has its own arrangements.
How many you can have
The product specification allows one device on each final ring circuit in the house. Network connection rules are tighter than that. Engineering Recommendation G98 Issue 2 Amendment 1 was approved by Ofgem on 11 August 2026, came into force on 27 August 2026, and holds you to a single device for the whole home. That is the number to work to, and it stands until the rule itself changes.
Is the device on the register?
A manufacturer may not put one of these on the market in Great Britain until the device has been type tested to G98, listed on the ENA Type Test Register and confirmed as compliant. A kit missing from that register has been through no assessment.
We look up the register entry before anyone orders anything. This page rests on Ofgem’s publication about the G98 change, the government’s final stage impact assessment and the interim product specification, all read on 13 September 2026.
