How to Register Plug-In Solar: ENA's myplugin.solar and What G98 Now Allows

If you’ve bought a compliant plug-in solar kit, you register it at myplugin.solar, a site run by the Energy Networks Association (ENA). You verify your email, confirm your address, pick your device from a list of compliant kits and submit. ENA then sends the notification to your Distribution Network Operator (DNO), the company that runs the cables in your area. The site says you can “register in just a few minutes”, and you don’t need an installer.

That’s possible because the grid connection rules changed. Engineering Recommendation G98 Issue 2 Amendment 1 2026, approved by Ofgem on 11 August 2026 and in force since 27 August 2026, says that for a plug-in kit “the Customer may take the role of Installer”. Before that, G98 assumed a qualified installer did the paperwork. Below is what the site does, what G98 now says, and where the two don’t line up yet.

Each page read at source. We didn't submit a registration, so the steps below are as ENA describes them.

Background

Our G98 guide

What myplugin.solar is

The site’s heading is “UK Plug-in Solar Registration”, and its footer says it’s “operated by Energy Networks Association Limited”, company number 04832301. ENA publishes G98 and runs the Type Test Register that every plug-in kit has to pass. DESNZ’s impact assessment planned for the device list to be “drawn from the ENA Type Test Register”, and the site’s FAQ says you’ll “only be able to select devices that are available on the approved device list”.

A few details from its Terms of Use (version 1, dated 26 August 2026, the day before the law changed):

• There’s no account. You get a one-time code by email, and “You do not create an account on the Registration Form to which you can return.”
• It covers independent networks. The registration goes to “the DNO or iDNO who supplies power to your property”.
• Moving house means registering again. If you put the kit up at a new home, “you will need to register the device at your new address”. Our moving house guide covers the rest.
• Help with the form goes through the Energy Saving Trust, not your DNO.

The four steps

1. Verify your email. “Continue with a one-time code.”
2. Confirm your address. “Enter your postcode and select your address.”
3. Select your device. “Choose one of the compliant devices.”
4. Submit your registration. Review it and submit, and “we’ll send your notification automatically”.

Have the manufacturer and model to hand exactly as printed on the kit, because the site searches by “manufacturer, model or device name”. The steps don’t mention an MPAN, the long supply number on your bill. The impact assessment planned for the system to “use the address information to pull the relevant MPAN”, which fits the address step, but we can’t confirm what the live form does without submitting one.

Is registering a legal requirement?

ENA’s answer is short: “Yes. Registering your plug-in solar device is a legal requirement.” The duty comes from the HSE exemption to the Electricity Safety, Quality and Continuity Regulations that G98 reproduces: whoever installs the generator must make sure the network operator is told “no later than 28 days (inclusive of the day of commissioning) after commissioning”. Under Amendment 1, for a plug-in kit, that person can be you.

The registration site doesn’t give a day count. Its FAQ says to register “once you have your plug-in solar device and know the address where it will be installed”. In practice that means around the time you plug it in, well inside 28 days. The product side says the same thing: IPS version 2 requires every compliant kit to carry a “statement that notification to distribution network operator (DNO) about connection and disconnection is mandatory”, and its documentation to include a QR code pointing to the registration process.

One device per household

The FAQ: “Each household can have one plug-in solar device with a maximum output of 800W installed at any one time.” That comes from G98 itself. The Amendment 1 draft says “Only one Plug-in Micro-generator is permitted in any given Customer Installation”, which Ofgem’s decision glosses as “effectively one per household”.

IPS version 2 allows one device per final circuit, but it says the G98 limit applies until G98 is amended, and Ofgem chose to keep it. One of its reasons was that a single device per home removes “the requirement for customers to verify that individual devices are connected to different final circuits within the property”. So a household can register one kit at a time. Our report on the per-circuit rule has the background. Swapping kits is fine: the FAQ says to register the replacement through the same “Register Plug-in Solar Device” process.

If your device isn’t on the list

ENA’s FAQ says a device that can’t be found “may still be undergoing assessment. Please check the list again after a few days before submitting your registration.” Only devices assessed as Compliant on the ENA register can be selected. As at 8 October 2026, 120 plug-in solar devices were Compliant, and our certified kits tracker lists them by model.

• Check the exact model. Use the name and reference on the label, not the listing’s family name.
• Non-compliant means not yet. On the register it’s a sub-status of “Further Information Required”: the maker has more to supply. It isn’t a safety finding, but the device can’t be selected until it moves to Compliant.
• A bare inverter won’t appear. Connect Direct says “We do not accept registrations for inverter-only products under the plug-in solar category.” The whole kit is what gets assessed.
• Not on the register at all? Then it isn’t on the plug-in route. It’s lawful to own, but it needs an electrician to connect it as a conventional installation, notified under G98 in the usual way. Our guide for anyone who’s already bought a kit goes through the options.

Already have solar panels? Two answers

This is where ENA’s registration site and the G98 text say different things, so we’ll give both.

ENA’s registration site, under “What should I do if I already have solar panels or another solar device at my property?”, says: “If you already have a 3.68 kW G98 solar system at your property, you must use a qualified installer to apply for G99 approval. Any additional generation must be wired in and not a plug-in installation.”

G98 Amendment 1, as Ofgem summarised it, says plug-in kits “are permitted to connect and operate alongside other permanently wired Micro-generators provided the aggregate Registered Capacity of all Micro-generators in the Customer’s Installation do not exceed G98’s existing 16 A per phase limit. Above this limit, Engineering Recommendation G99 requirements apply.”

They agree on a full-size system. A rooftop system already at 3.68 kW on a single-phase supply is at the G98 limit, so anything added takes the home over 16 A and into G99, which needs an application before you connect. They differ on a smaller one. On the G98 text, a 2.5 kW rooftop inverter plus an 800 W kit comes to 3.3 kW and stays inside the limit. ENA’s answer doesn’t cover that case, and its last sentence reads as a wider rule. Until one of them changes, ask your DNO in writing before you plug a kit in next to existing solar, and keep the reply. Our DNO lookup tells you who to ask.

What G98 Amendment 1 changed

The change went out for consultation as DCRP/26/02 on 5 June 2026, closing on 30 June 2026 (Distribution Code consultations). Ofgem approved it on 11 August 2026 and directed that it take effect when the plug-in law came into force, which SI 2026 No. 848 did on 27 August 2026. For householders, the draft:

• Defines a Plug-in Micro-generator as one with “a Registered Capacity of 800 W or less, fitted by the Manufacturer with a plug complying with BS 1363 or BS EN IEC 60309, and designed to be connected only via the Manufacturer’s plug”.
• Allows one per Customer Installation, alongside wired generation if the total stays within 16 A per phase.
• Lets the customer notify. “For Plug-in Micro-generator(s), the Customer may take the role of Installer.”
• Adds two customer forms. Form B2 is the installation document for a plug-in kit and Form D2 is its decommissioning notice. The old Form B and Form D become B1 and D1 for wired systems.
• Drops five installer requirements for plug-in kits: the cut-out photograph, installation wiring and isolation, the labelling rules for permanently wired plant, installer competencies, and the functional check on loss of mains protection. The exemptions “do not remove any requirement for the Customer’s Installation to conform with BS 7671”, so the Wiring Regulations still apply to your sockets.
• Asks for a warning label about the hazards of sources of electrical energy, fixed near the cut-out or consumer unit, where a plug-in kit is installed.
• Mentions landlords. A footnote to the multiple-premises procedure says a landlord-led project across flats in one building is an example of that procedure, and the consultation paper says it “does not create any new obligations on landlords”. Renters should read our renters’ guide for the permission side.

How myplugin.solar relates to the G98 forms

Form B2 is G98’s own householder notice for a plug-in kit. The draft asks for your details and MPAN, where in the home the kit is, the manufacturer, the register reference, the capacity and phase, and a signed declaration that no more than one plug-in kit is connected and that any other generation keeps the total within 16 A per phase. It has no installer block, no isolator, no schematic and no cut-out photo. It also says: “As an alternative for completing this form, a Customer connecting a Plug-in Micro-generator may use the connect and notify process through the Connect Direct platform.”

myplugin.solar is the public front of that platform. Connect Direct’s own DNO screen describes a plug-in submission as complete “when a consumer registers their Plug-in Solar device on the myplugin.solar website”. None of the six DNOs publishes a Form B2 or D2 yet: their form pages still carry the older A, B, C and D set. So for a plug-in kit, myplugin.solar is the route that exists. Our G98 form guide covers Form B1 for wired installations and what B2 asks.

Taking a kit down for good is the gap. The site’s FAQ covers replacing a device, not removing one, and G98’s answer, Form D2, isn’t offered by any DNO yet. If you remove a kit permanently, email your DNO with the address, the device and the date, and keep the reply.

The DNO side isn’t live yet

Connect Direct’s release notes list version 3.3.0 as “UPCOMING”, date “TBC”, and describe it like this: “ENA Connect Direct 3.3.0 brings the DNO-facing side of Plug-in Solar notifications online. DNOs can now view, filter and respond to consumer Plug-in Solar notifications, and assign an export MPAN.” So on 8 October 2026 the screens DNOs use to handle these notifications hadn’t been released. Don’t expect a reply from your DNO yet, and keep your own record: a screenshot of the confirmation screen, and any email that arrives.

The DNOs’ own pages haven’t caught up either. None of the G98 pages we read mentions plug-in solar, and they still describe an installer route. UK Power Networks says “Only installers can notify us on behalf of customers.” Northern Powergrid says “your installer will need to notify us”. Electricity North West’s FAQ says “the installer must submit a Form B”. Those pages were written for wired systems. For a plug-in kit, G98 now lets the customer notify, and myplugin.solar is ENA’s route for doing it. Our G98 guide links to each operator’s process for wired installs.

The same release is the one that lets DNOs assign an export MPAN, which an export tariff depends on. The impact assessment expected plug-in owners to “need to register their panels to gain potential access to export tariffs”. Our guide to export payments without MCS covers what suppliers ask for today.

What to do now

1. Check the kit is Compliant on the tracker, by the model on its label.
2. If you already have solar, read the section above and ask your DNO before plugging in.
3. Register at myplugin.solar once you have the kit and know where it’ll go. One kit per household.
4. Keep a record of the submission, because no DNO reply is likely until the DNO side goes live.
5. Register again if you move, and tell your DNO in writing if you take the kit down for good.
