Plug-in solar panels
17 September 2026
Have you been tempted to buy plug-in solar panels to reduce your energy costs?
They can offer benefits, but please be aware that they’re not suitable for every home.
Before buying, installing or connecting plug-in solar panels, please note the following safety points:
- Speak to us before you buy or install these panels. We might have to run some checks first.
- Be aware that your existing socket may not be able to accommodate the panels safely.
- You’ll need a competent electrician to confirm the installation and circuit are suitable.
- Just because you have a satisfactory Electrical Installation Condition Report (EICR), it doesn’t mean your circuit is suitable for plug-in solar.
- Don’t use an extension lead, multiway adaptor, cable reel or similar for these panels – they can overheat.
- Use a reputable supplier and make sure the system is intended for the UK market, meets the required product specification and appears on the ENA product register.
- A maximum plug-in solar output of 800W per household is currently allowed. Don’t add extra units, or connect systems to several sockets, to try to generate more output.
- Solar panels can be large and heavy. They need to be positioned so they can’t fall, damage the building, block access or create a hazard to other people.
- Connecting a plug-in panel is different to plugging in an ordinary appliance. You must notify the relevant Distribution Network Operator (find yours here) – and you may have to consider buildings insurance or other requirements.
- Keep the product information, model number and installation details in a safe place as you’ll need to register the system with the manufacturer. This is so you can be contacted if there’s a safety notice or product recall.
