Plug-in solar panels

What you need to know

Plug-in solar panels (sometimes referred to as plug-and-play systems) offer a straightforward way to generate clean, renewable electricity directly from sunlight using a standard household socket.

From Thursday 27 August 2026, Government rules changed to allow plug-in solar panels to be legally sold in the UK. The panels are now widely available in DIY shops and High Street retailers. Please see below for information and important guidance on these plug-in solar systems.

Please let us know before buying and using one of these systems in your home by contacting buildingsafety@goldinhomes.org.uk

How they work:

Sunlight hits the photovoltaic cells on the panel, producing a direct current (DC) of electricity. A connected microinverter then converts this into alternating current (AC), making it safe to plug straight into a standard domestic socket to power everyday appliances.

Potential savings:

Systems can help lower electricity bills by producing homegrown energy for everyday items like fridges, TVs, and device chargers. The Energy Saving Trust has estimated that an 800 watt system (maximum legal size for plug-in systems) could save around £70-100 off the average annual electricity bill. 

Permissions:

Because these systems simply plug into an ordinary socket, we don't need you to seek formal permission solely for plugging a compliant unit in. However, you should always check if any other local conditions or lease terms apply and please let us know if you have a plug-in solar in your home home.

Would plug-in solar work for me?

Like all solar systems, plug-in solar will work best when facing south, where it can get direct sunlight free from shade. 

If I get a plug-in solar system do I need to register it?

Yes. You’re legally required to register any plug-in solar panel devices before you use them in the UK. You can register using the UK Plug-in Solar Register website

Electrical and fire safety guidelines

While plug-in solar panels provide an accessible route to renewable energy, safety remains paramount. You must adhere to our existing electrical and fire safety policies.

  • Fire safety & escape routes: Standard fire safety rules apply. Nothing associated with a solar setup should ever obstruct escape routes, fire doors, firefighting access, or safety equipment. Existing guidelines regarding items stored or installed on balconies, in gardens, or within communal areas must be strictly followed.
  • Battery storage warning: Any systems incorporating integrated battery storage aren't permitted to be plugged into the mains in the UK. You can plug the panels into portable power storage devices like Jackery portable power stations to charge them, but these can't be plugged into the mains to provide electricity, even during power cuts. 
  • Manufacturer instructions & compliant products: Customers must always follow the manufacturer’s instructions carefully and use fully compliant, certified products – compliant systems currently start from around £450. 
  • Cable runs: Cables should not be run through door frames or seals has this can stop fire doors closing properly or block escape routes.
  • Safe connection: Plug-in solar units must be plugged directly into a fixed wall socket. They must never be connected through extension leads, multi-socket adaptors or overloaded sockets.
  • Use sockets that are in good condition: Sockets must be in good condition with no cracks or breaks, and the plug in solar should be the only appliance plugged into the socket.
  • Competent professional work: Any new electrical work required to support a setup — such as installing a new outdoor socket — must be undertaken by a competent, qualified professional to ensure it meets all relevant electrical safety standards. Where an additional socket or fixed installation work is required, please contact us to check if permission is needed before proceeding.
  • Fixings and mountings: If you plan to fix the panels to a wall or balcony using brackets or frames, please contact us first as we'll need to make sure the instillation won’t impact fire-stopping or access. Please check if permission is needed before proceeding.
