Plug-in Solar

Solar you plug in yourself.
Paperwork we file for you.

From 27 August a certified plug-in kit goes straight into a normal socket, no electrician needed. One thing still has to happen: your network operator needs telling within 28 days. That's the bit we do. £10, one page, your kit and your address, done in about a minute. No account, no sign in.

How it works

What changed on 27 August 2026

Plug-in solar is legal. The notification stayed.

New rules (SI 2026/848) mean a solar kit in Great Britain can go in the wall and start generating the same afternoon, as long as it's on the government's spec: panel with the inverter built in, capped at 800 watts, ordinary three pin plug, solar only, and listed on the ENA's Type Test Register. Off that register, it can't legally be sold as plug-in. Whatever the box says.

The consultation asked for the notification to be scrapped too. Government said no. So every kit still owes a G98 notification within 28 days of being plugged in, same form an installer files for a full system, just owed by the householder this time.

How it works

Six things CLRD does, so you don't have to.

You fill in one page: your kit, your address, the MPAN off your bill, and a signature. Everything below happens behind it, on the same engine MCS certified installers file with every day.

  1. 01

    Finds your network operator

    The first two digits of your MPAN identify the operator for your property. CLRD resolves it the same way it routes an installer's job, and validates the number as you type, so the notification can't reach the wrong one.

  2. 02

    Matches your kit to the register

    Your kit is looked up in the ENA Type Test Register, the same register CLRD holds for professional installations, and goes onto the form exactly as its entry reads. If it isn't on the register it isn't a lawful plug-in kit, and you find that out here rather than after you've filed.

  3. 03

    Checks nothing else is generating

    Operators assess everything at a property together. CLRD asks first, and if there's an existing system or a second kit it stops rather than files, and puts you in front of a person on our team.

  4. 04

    Fills the G98 Form B

    The official notification, completed from what you entered and the register entry, in the form your operator expects. No blank fields, no guessing which boxes apply to a plug-in kit.

  5. 05

    Draws the single line diagram

    Your operator expects a schematic showing how the kit connects to your supply. CLRD draws it from the register entry. It's the part of the notification you would otherwise have to draw yourself.

  6. 06

    Files it and brings the answer back

    CLRD submits the form and the diagram to your operator from the platform, then sends you the pack exactly as it was filed, yours to keep. Their acknowledgement follows into the same place and forwards to you, usually within 24 hours.

The check the £10 includes

Already generating?
We look before we file.

Network operators count everything at a property together, not kit by kit. So if yours isn't the only thing generating, a straight notification might be the wrong answer. That's the first question on the form, and a "no" doesn't go into a form at all, it goes to a person on our team who'll tell you what your setup actually needs before anything's sent.

Installer sat on a stack of connection paperwork? Different conversation. That's Managed Jobs.

Questions

What householders ask.

Do I really have to notify anyone?
Yes. The law that made plug-in solar legal kept this requirement deliberately: a G98 notification to your electricity network operator within 28 days of plugging the kit in. It isn't an application, you don't need permission or approval for a certified kit, but the operator running your local network must be told it's there.
Can't I file it myself for free?
You can. The G98 form is a public document, and your network operator will accept it from you directly. CLRD's £10 does it in about a minute: your kit stated exactly as its register entry describes it, the right operator worked out from your MPAN, a single line diagram included alongside the form, the notification filed, and the operator's acknowledgement letter forwarded to you, usually within 24 hours, with your filed copy.
Which kits qualify?
Only kits certified on the ENA Type Test Register may be sold as plug-in solar in Great Britain. The list you pick from on CLRD is read straight from that register, so it's always the current one. If a kit you're considering isn't on it, it isn't a lawful plug-in kit.
What's an MPAN?
The 13-digit number printed on your electricity bill beneath a boxed S, the permanent identity of your property's electrical connection. Its first two digits identify your network operator, which is how CLRD knows where to send the notification. The number is verified as you type it.
I already have solar panels, or a second kit.
Tell us, it's the form's first question. Generation at a property is assessed together, so a kit on top of an existing system can need a different route. A person on our compliance team will look at what you have and tell you what it actually needs before anything is filed.
When does this start?
Certified plug-in kits become legal to self-install in Great Britain on 27 August 2026, and this service opens with them. Northern Ireland connects under different rules and isn't covered.

From 27 August 2026.

The kit goes in the socket. The notification takes a minute. £10, one page, done.
