Around 4.4 million households in England rent privately. Most have been locked out of conventional rooftop solar — they don't own the roof, most landlords won't consent to permanent structural changes, and the economics of installing solar on someone else's property are not complicated to calculate.
Plug-in solar changes the calculation, and the Renters' Rights Act 2025 has added legal teeth to back it up. Landlords in England and Wales cannot unreasonably refuse a tenant's request to install a portable plug-in solar system. Reasonable grounds for refusal include genuine structural concerns, listed building restrictions, or electrical capacity issues. "I don't want it" is not a reasonable ground. That's the law now.
What landlords can and can't refuse
The key legal distinction is between permanent modifications and portable equipment. A plug-in solar kit with no permanent fixings — panels on a ground mount or balcony stand, plugged into an existing socket — is portable equipment. The landlord has very limited grounds to refuse this. This is only possible because BS 7671 Amendment 4 now permits sub-800W systems on standard sockets without an electrician. A kit requiring drilling into the building fabric or modifying the electrical board is a different matter and subject to different rules.
A balcony kit on adjustable feet or a garden ground-mount is in the strongest legal position. A fence-mounted kit with screws is more ambiguous depending on whether the fence is the landlord's property.
Which plug-in solar kits work best for renters
Portability matters above all else. When you move, the kit moves with you — that's the entire financial case at £419–£499. Around 285,000 flats in England have balconies suitable for a rail-mounted or freestanding kit. A much larger number of rented houses have gardens where a ground-mount works perfectly.
The EcoFlow STREAM and Anker SOLIX RS40P are both well-suited to renter installs — lightweight, no permanent fixings required, portable enough to move in a car. Both have UKCA certification, which matters if your landlord asks for compliance documentation. For a full comparison see our plug-in solar for renters guide.
