G98 form walkthrough, without the paperwork fog
Last reviewed: 31 August 2026. After you fit plug-in solar from 27 August 2026, you send a G98 notification to the electricity network. The first time I read the form, I thought I'd downloaded the wrong document. This is the plain version.

What is a G98 notification?
A G98 notification is what you send to your Distribution Network Operator (DNO) after you've connected a small generator to the grid. In this case, that means plug-in solar up to 800 VA and up to and including 16 A per phase. It's a notification, not an application. You don't ask permission; you tell the network within 28 days that it's been fitted.
For a compliant, type-tested kit, the DNO normally doesn't need to approve it first. The network can still assess the notification, query it, or reject it if the details don't meet the requirements. The paperwork trail comes from ENA G98 Issue 2 Amendment 1 2026 and SI 2026/848 for Great Britain. Worth knowing. Not worth framing.
G98 vs G99 — what's the difference?
G98 covers small generators up to and including 16A per phase, including single-phase plug-in solar up to 800 VA. You notify after installation. G99 is for bigger systems over 16A, where you apply first and wait for DNO approval. Plug-in solar kits sit on the G98 side of the fence. Our G98 notification guide has the regulation detail if you want the longer read.
The G98 amendment changes how you notify
On 11 August 2026, Ofgem approved DCRP/MP/26/02 — the G98 amendment that gives plug-in solar a formal grid-connection route. It confirms one plug-in kit per household, allows a kit alongside existing solar within the 16 A per phase limit, and introduces consumer self-notification. The ENA consumer portal is now live at myplugin.solar; it is separate from Connect Direct, which remains the industry-facing route. Use this walkthrough to prepare a clean record, then submit through the live G98 notification route before you send anything.
What you need before you start
Before you touch the G98 form, put the boring facts in one place. It saves you hunting through manuals halfway through, which is how these five-minute jobs become an evening.
- Use your electricity bill to find your MPAN. Bills may show a 21-digit Supply Number; the 13-digit MPAN core is the part normally used on forms.
- Read the inverter model number from the inverter label or the product documentation.
- Have the panel model details to hand, and count how many panels are fitted.
- Use the installation date as the date you first plugged the system in.
- Enter your postcode so the tool can suggest the likely electricity network operator, which you confirm before download.
Use our free tool instead
The G98 form generator asks for these details in a sane order. It suggests the likely network from your postcode area, then gets you to confirm it before making the PDF. Mine took about 5 minutes once I had the MPAN.
What the form is asking for
| Field | What it means | Where to find it |
|---|---|---|
| Installer name | Your name (if DIY) or your installer's name | Your own name |
| Installation address | The property where the solar kit is installed | Your home address |
| MPAN | 13-digit MPAN core identifying your electricity supply point | Your electricity bill, sometimes inside a 21-digit Supply Number |
| DNO | Distribution Network Operator for your area | Auto-looked up from your postcode (our tool does this) |
| Inverter manufacturer | Brand of the microinverter (e.g., EcoFlow, Anker) | Printed on the inverter or in the product manual |
| Inverter model | Specific model number of the microinverter | On the inverter label or product documentation |
| Inverter capacity (VA) | Rated AC output of the inverter in VA | Product spec sheet (max 800 VA for plug-in) |
| Number of panels | How many solar panels are connected | Count them (typically 1–4) |
| Panel manufacturer & model | Brand and model of the solar panels | On the back of each panel or in the kit documentation |
| Total installed capacity | Sum of all panel wattages (e.g., 2 × 400W panels = 800W DC, but inverter AC output must not exceed 800 VA) | Calculate: panel wattage × number of panels |
| Installation date | The date you first plugged the system in | The day you connect it to the socket |
| Type of generation | Solar PV (photovoltaic) | Always "Solar PV" for plug-in solar |
| Phase | Single-phase or three-phase | Almost always "Single-phase" for GB homes — pick three-phase only if your supply actually is one |
How to fill it in
- Start by finding your MPAN on your electricity bill. Some bills show a 21-digit "Supply Number" or "S number"; the bit you usually need is the 13-digit MPAN core inside it. If it isn't there, ring your electricity supplier and ask for it by name.
- Work out your network operator. This is the company that owns the local wires to your home, not the firm billing you every month. Put your postcode into the G98 form generator and it'll suggest the likely network from your postcode area. Check it before the PDF is made.
- Complete the signatures. If it's a self-install, type your own name in both the customer and installer signature boxes. Yes, that's a real thing they ask for.
- Gather your kit details from the label or manual. For the panels, note the manufacturer and model. Total capacity is panel watts × number of panels.
- Fill in the form using the G98 form generator if you don't fancy typing the same facts into a network form by hand. It takes about 5 minutes and follows the 4-step wizard (Your Kit → Your Home → Installation → Download & Send).
- Download the PDF the tool produces. It's a completed G98 notification with your details filled in. Open it once before you send it. Paperwork has a sense of humour.
- Submit the notification through myplugin.solar, ENA's consumer portal — that's the official route for compliant plug-in devices. The prepared PDF is your record copy, not a portal upload; keep it with the portal acknowledgement.
What happens after you send it?
The DNO will usually acknowledge the notification within a few days. You don't need to wait for that email before using the system. As long as you notify within 28 days of installation, your side of the job is done. The DNO may send a confirmation letter or email.
Keep any confirmation letter or email. If you've heard nothing after 28 days, contact the network operator and ask them to confirm receipt. The practical takeaway is simple: send it and keep proof. Then get on with your life.
Questions people ask after reading the form
Can I install before 27 August 2026?
No. And from 27 August 2026 onwards, only IPS-compliant devices can be installed. The G98 notification only makes sense after the system has been legally connected, so don't submit one for an installation before that date.
Do I notify before or after plugging it in?
After. G98 is a notification, so you connect the system and then notify within 28 days. Pre-approval is the G99 world, and that's for larger systems.
What if I move house?
If the kit comes with you, submit a new G98 notification for the new address within 28 days of installing it there. If you leave it behind, tell the network operator the device is being removed so the record for that address stops listing it. Add it to the moving list, somewhere between broadband and wondering where the kettle went.
Can I post the G98 form?
The official route is ENA's consumer portal at myplugin.solar — the portal takes the notification; the postman stays retired. The tool shows the checked route for the network you confirm before download, which is less glamorous than a stamp but usually more useful.
