Plug In Solar Panels UK 2026: Prices, Savings, Rules and Where to Buy

Last updated: 27 August 2026

From 27 August 2026, plug in solar panels became legal to buy and use across Great Britain. This guide explains what changed, how much they can generate, what they might cost, who could benefit and where to look for compliant products.

What are plug in solar panels?

Plug in solar panels are small solar generating kits designed to connect directly to a standard household mains socket. Unlike a conventional rooftop solar system, a compliant plug in solar kit does not require the same type of fixed electrical installation.

They are intended to generate electricity that a household can use while it is being produced, reducing the amount of electricity bought from the grid. Only compliant products intended for the Great Britain market should be used.

The current position

What changed on 27 August 2026?

Plug in solar became legal across Great Britain from 27 August 2026. This is no longer a proposed or future change; the rules are now in force.

Compliant plug in solar kits can connect directly to a standard household mains socket, provided the system complies with the applicable Great Britain plug in solar safety and product requirements. The maximum AC output is 800W.

This does not mean any solar panel and inverter bought online can simply be plugged into a UK socket. Only compliant products intended for the Great Britain market should be used, and they should be installed and operated according to the manufacturer's instructions.

How much electricity can they generate?

Government states that an appropriately positioned system could provide up to approximately 20% of an average household's electricity use. Actual generation depends heavily on panel position, orientation, shading and household electricity consumption.

Crucially, the value comes from using generated electricity within the home while it is being produced. How much you benefit depends on how much of that generation you use rather than how much the panels produce in total.

How much could they save?

Government estimates potential electricity bill savings of up to approximately £110 per year. This is an estimate, not a guarantee.

Actual savings depend on how much generated electricity is used in the home, household consumption patterns, panel position and orientation, and current electricity prices. We do not claim guaranteed savings.

How much do they cost?

This is a newly launched market, so prices will develop as more compliant products reach retailers. There is no single definitive market price.

Cost is affected by product specification, panel capacity, mounting equipment and the retailer. As the UK market matures, a clearer picture of typical pricing should emerge. Treat any single price you see quoted as indicative rather than fixed.

For context, plug in solar is generally expected to be a lower cost entry point into home solar generation than a conventional professionally installed rooftop system. See our main solar PV guidance for the factors that shape a full rooftop installation.

Who could benefit?

Plug in solar may be particularly useful for people who cannot, or do not want to, install a conventional rooftop system. This includes:

  • Renters, with any necessary landlord permission
  • Flat and apartment residents with suitable private outdoor space
  • Leaseholders, subject to any relevant permissions
  • Homes without suitable rooftop solar access
  • People wanting a lower cost entry point into home solar generation

It is worth being clear about expectations. Conventional, professionally installed rooftop solar will normally provide substantially greater generation and may be more appropriate for homeowners with suitable roofs and larger electricity requirements.

Plug in solar vs rooftop solar

A simple way to think about the difference, without turning this into a technical comparison:

Plug in solar

Lower initial cost. Connects to a standard socket without fixed installation. Smaller system size, capped at 800W. Modest generation suited to reducing daytime grid use. Well suited to renters and flats with permission. Limited long term energy potential compared with a full roof array.

Rooftop solar

Higher initial cost and a fixed, professional installation. Much larger system size and generation. Suited to homeowners with suitable roofs. Substantially greater long term energy potential, and more likely to justify adding battery storage.

Where can you buy plug in solar panels?

Compliant products are beginning to appear through major UK retailers and specialist solar suppliers. Because this market only opened on 27 August 2026, availability will grow as more compliant kits reach retailers.

Buy compliant equipment from reputable manufacturers or retailers, and confirm that any product is intended for the Great Britain market before purchasing. We have not invented product availability or inserted affiliate links here. This section is structured so genuine retailer or affiliate links can be added later as the UK market develops.

Read carefully

Safety and permissions

Buy compliant equipment from reputable manufacturers or retailers and follow the manufacturer's installation and operating instructions. Panels must not obstruct fire escapes, balconies, windows, shared access routes or emergency access.

Renters should obtain any necessary landlord permission, and leaseholders or flat owners may need freeholder or managing agent permission. Planning, building and property restrictions can still apply depending on where and how panels are installed.

If you have concerns about the condition of your home's electrical installation, obtain appropriate professional electrical advice before connecting a system. This guide does not provide DIY electrical modification instructions.

Registration and export

Treat plug in solar primarily as a way to reduce electricity purchased from the grid by using generated electricity within the home. Do not assume Smart Export Guarantee payments or export income will apply.

Any registration or notification requirements should be confirmed through official sources rather than assumed. We have not described a simplified registration process, because one is not confirmed and operational in a form we can state with confidence. Confirm the current position with official guidance before relying on it.

FAQs

Plug in solar questions answered

Are plug in solar panels legal in the UK?

Yes. From 27 August 2026, compliant plug in solar kits can be bought and used across Great Britain. They must meet the applicable Great Britain plug in solar safety and product requirements, and a compliant system can connect directly to a standard household mains socket without the fixed electrical installation conventional rooftop solar requires.

How much electricity can a plug in solar system generate?

The maximum AC output is 800W. Government suggests an appropriately positioned system could provide up to around 20% of an average household's electricity use. Actual generation depends on panel position, orientation, shading and how much generated electricity is used while it is being produced.

How much could plug in solar save on electricity bills?

Government estimates potential savings of up to around £110 per year. Savings are not guaranteed and depend on how much of the generated electricity you use in the home rather than how much the panels produce in total.

Can renters and flat owners use plug in solar?

They are one of the groups who could benefit most. Renters should obtain any necessary landlord permission, and leaseholders or flat owners may need freeholder or managing agent permission. Planning, building and property restrictions can still apply depending on where and how panels are installed.

Can I export electricity from plug in solar for payment?

Plug in solar should primarily be seen as a way to reduce electricity bought from the grid by using generation within the home. Do not assume Smart Export Guarantee payments or export income will apply. Any registration or notification requirements should be confirmed through official sources before relying on them.

Thinking about a full rooftop solar system?

If you own your home and have a suitable roof, a conventional professionally installed solar system will normally generate far more. You can also check what energy grants may be available.
