Do I need an electrician to install plug-in solar in the UK?

The short answer

If you buy a compliant plug-in solar product after the new rules take effect, your existing electrical installation is suitable and you can follow the manufacturer's instructions without altering the fixed wiring, then you should not automatically need an electrician just to install and plug in the product.

That is really the point of the new system. Government has created a product route specifically so small plug-in solar can be sold as a consumer product rather than every installation having to follow the traditional fitted-solar route.

Where I think people will get caught out is turning that into: "plug-in solar is DIY, therefore my electrics don't matter." They still matter.

What changed?

The final UK Interim Product Specification is much clearer than the early announcements were. It sets out a route for a complete plug-in solar product with a maximum AC output of 800 VA, a manufacturer-supplied non-rewireable BS 1363 plug fitted with a 5 A fuse, defined safety functions and detailed instructions for the householder.

Those instructions have to cover things such as checking the consumer unit, identifying the socket circuit, residual-current protection, mounting, DNO notification and situations where professional advice is needed.

So this is not government saying that electrical safety no longer matters. It is government trying to put enough safety requirements into the product and its instructions that a suitable householder installation can be straightforward.

When you probably do not need an electrician

A straightforward installation should look something like this:

• you have bought a complete product that genuinely meets the UK plug-in solar requirements,
• the product is being used exactly as the manufacturer supplies and instructs,
• the existing socket circuit can be identified,
• the consumer unit and residual-current protection meet the product instructions,
• no fixed wiring has to be altered,
• no new circuit has to be installed,
• the panels can be mounted safely using the supplied/approved arrangement,
• and you are comfortable completing the required DNO/G98 paperwork.

In that situation, paying an electrician simply to put a factory-fitted plug into a suitable socket would rather defeat the point of the new product category.

When I would get an electrician involved

This is where I would draw the line. If any of the following applies, I would stop treating it as a simple plug-in job:

• You cannot work out which circuit the socket is on.
• The consumer unit is old, unclear or uses older protection.
• The required residual-current protection is not present or you are not sure what you have.
• A new socket, new circuit or consumer-unit alteration is needed.
• The existing circuit has known faults, damage or questionable wiring.
• The product instructions tell you to obtain professional assessment.
• You simply cannot answer the electrical checks in the manufacturer's instructions confidently.

The final IPS itself says that where the consumer unit does not meet the required criteria, or the user cannot clearly identify the protective devices, they should seek professional advice.

What about RCDs and RCBOs?

This is one of the areas where I would expect householders to need the most help.

The product instructions must tell the user how to check the consumer unit and whether suitable residual-current protection is present. A modern board with clearly labelled devices is one thing. An old board where the user cannot tell what protects the sockets is another.

I would not advise somebody to start removing covers or trying to prove circuit details they do not understand. The sensible DIY check is limited to what the manufacturer tells the user to do safely. If that does not give a clear answer, get somebody competent to check it.

There is a separate guide on RCBOs, bidirectional current and plug-in solar.

How do I know which socket circuit I am using?

This is another useful part of the final specification. Manufacturers are expected to explain how a householder can identify sockets on the same final circuit.

In simple terms, that normally means identifying the relevant protective device at the consumer unit, switching that circuit off and checking which sockets have lost power. Sockets that go off together are on the same circuit.

That tells you which final circuit you are dealing with. It does not necessarily tell a householder whether the wiring behind the walls is a ring final or a radial circuit.

I have gone into that properly in the plug-in solar ring final, radial and socket circuit guide.

Does the circuit have to be a ring main?

No. This is another point I want to be careful with because people are already shortening the new rule to "one plug-in solar per ring main".

The specification talks about suitable final circuits and gives socket circuits as the intended connection. UK socket circuits can be ring finals or radials. What matters is whether the particular circuit and protection meet the product requirements.

Lighting circuits and circuits dedicated to fixed equipment such as cookers or boilers are not the intended connection route.

What if I need a new dedicated circuit?

Then the situation changes.

A new circuit from the consumer unit is not part of simply unpacking and plugging in a consumer product. It is fixed electrical installation work.

In England, installing a new circuit in a dwelling is generally notifiable work under Part P of the Building Regulations. It needs to be properly designed, installed, inspected, tested, certified and notified through the correct route.

So there is nothing wrong with deciding you want a dedicated circuit for your solar connection. In some homes it may be the cleanest option. But at that point I would use an electrician rather than pretend it is still a no-electrical-work DIY installation.

Does BS 7671 disappear because the product has a plug?

No.

The fixed electrical installation still exists and still has to be safe. The new product framework does not magically turn poor wiring into good wiring or remove the importance of circuit protection.

The practical difference is that a compliant consumer product is being designed so the householder does not have to design a PV electrical installation themselves. That is very different from saying the Wiring Regulations no longer matter.

What about G98? Can I do that myself?

Yes, the paperwork side should not be confused with electrical installation work.

Plug-in solar is still generation connected in parallel with the public network, so the DNO/G98 process still matters. The final IPS requires the manufacturer to give the user instructions for the relevant network notification.

You do not need to be an electrician simply to fill in a form with the information supplied for your product. Where the exact network process is unclear, check the product instructions and your DNO's current requirements rather than guessing.

Our G98 form guide and plug-in solar registration guide cover this separately.

The IET is still more cautious than government

This is worth including because readers deserve both sides rather than being told that the legislation has made every concern disappear.

The IET welcomed progress towards a framework but has continued to warn about the variation in the condition and age of UK domestic electrical installations. Its July 2026 statement recommended that the existing electrical installation is assessed by a competent electrician before plug-in solar is connected.

That is professional safety advice, rather than the same thing as saying the legislation requires an electrician for every compliant product.

My own view sits somewhere practical in the middle: if the installation is modern, clear and meets every check in the product instructions, the self-install route is the whole point. If the electrical side starts becoming uncertain, an electrician's check is cheap compared with guessing.

What about batteries?

The new plug-in solar IPS does not cover plug-in battery systems or plug-in solar products incorporating electrical energy storage.

That is important because some products sold in Europe combine balcony solar and batteries and can look very similar to the products people expect to see here.

Do not assume that because the solar-only product route changes on 27 August, every socket-connected battery product gets the same treatment. Read the separate UK plug-in battery storage guide.

What about mounting the panels?

An electrician is not automatically the right person to decide whether a balcony rail, fence, wall or lightweight roof can safely take a solar panel.

The complete plug-in solar product includes its mounting arrangement and the manufacturer has responsibilities around safe installation. Follow those instructions exactly.

If the proposed location needs structural alterations, custom brackets or a mounting arrangement that is not covered by the product, that is another sign you are moving away from the simple consumer-product route.

DIY or electrician? A simple guide

What I would check before buying

• Is this the complete UK plug-in solar product, not just a compatible inverter?
• Does the documentation show that it is intended to comply with the final UK Interim Product Specification?
• Is the BS 1363 plug and 5 A fuse supplied by the manufacturer as part of the product?
• Can I identify the final circuit I intend to use?
• Can I understand and pass the consumer-unit/RCD checks in the instructions?
• Will I need any new fixed wiring?
• Is the mounting arrangement supplied or approved for the location I intend to use?
• Does it include a battery? If so, do not assume the new solar-only route applies.
• What does the manufacturer say about G98/DNO notification?
