Plug-in solar panels are now legal: How to enjoy solar safety
01 September 2026
From 27th August, households across the UK can install plug-in solar panels for the first time, making small-scale renewable energy more accessible than ever. While the technology could help some homeowners lower their energy bills, Zurich is urging people to understand the risks before connecting new equipment to their home's electrical system.
Industry experts have warned that not all properties are ready for plug-in solar. Older wiring, inadequate electrical protection and incorrectly installed equipment can increase the risk of overheating, electric shock and, in the most serious cases, fire. As demand grows, homeowners should ensure their property is suitable and that any equipment meets UK safety requirements.
Zurich is encouraging customers to take a ‘solar safe approach’. Before installing plug-in panels, homeowners should understand how the system will interact with their existing electrics, carry out appropriate checks and follow manufacturer guidance. Taking a few sensible precautions can help reduce the risk of damage to both the property and the technology itself.
Megan Dunford, Large and Complex Clam at Zurich at Zurich UK, said:
“Plug-in solar panels promise cheaper, greener energy, but they shouldn’t be treated like a plug-and-play gadget. Fundamentally, you’re adding a mini power station on your home, so you need to go into it with your eyes open.
“The big difference is, these systems feed electricity directly into your home’s electrical network and, if wiring is outdated, poorly maintained or unsuitable, there is a risk of electrical faults, overheating and potentially fire.
“Before installing plug-in solar, homeowners should make sure their electrics are up to the job, use certified equipment and follow manufacturer guidance. If there’s any doubt about the condition of a property’s wiring, it’s worth getting it checked by a qualified electrician.
“The savings from solar can be quickly wiped out by the cost of repairing avoidable damage. A few simple checks before you plug in could make all the difference between enjoying the benefits of renewable energy and facing a costly insurance claim later on.”
Five tips for plug-in solar safety
1. Get your wiring checked
If your home has older wiring or you are unsure of its condition, arrange an Electrical Installation Condition Report (EICR) or inspection by a qualified electrician before installing a system.
2. Buy certified equipment from reputable suppliers
Only purchase plug-in solar panels that meet UK safety requirements and are certified for use in the UK. Take extra care when buying through online marketplaces, where products may not always comply with the latest safety standards or regulatory requirements.
3. Plug directly into a wall socket
Never connect plug-in solar panels through an extension lead, multi-plug adaptor or other temporary connection. Always use a suitable fixed wall socket and follow the manufacturer's instructions.
4. Inspect and maintain your system
Regularly check for damaged cables, loose connections, signs of overheating or water ingress. Plug-in solar should not be treated as maintenance-free and should be inspected periodically to ensure it remains safe.
5. Know the rules for your property
Current proposals limit plug-in solar installations to a maximum output of 800W per household – this means one unit per household. If you rent your home, live in a flat, or need to install panels on an external wall, balcony or other communal structure, seek permission from your landlord or freeholder before installation. Solar equipment should also be considered as part of any building fire risk assessment.
While reducing energy costs is a clear priority for many households, it is important this is achieved without compromising on safety or risk to property.
