U.K. tenants in apartment blocks could see lower electricity bills and receive up to £160 ($214) a year through a shared solar-and-battery scheme, without installing equipment in their homes or changing energy suppliers.
Here's what to know
The FlatSave scheme brings together solar technology company Allume Energy, energy supplier E.ON Next, and the housing association Peabody, Inside Housing reported.
A communal battery supports Britain's grid during peak demand by storing electricity when prices are low. The battery and a single rooftop solar installation serve multiple flats, giving households access to shared solar power.
FlatSave claims the arrangement can save tenants up to 60% on bills, leaving them hundreds of pounds better off annually, according to Inside Housing. Residents also receive a guaranteed annual grid payment of up to £160 ($214).
For homeowners exploring individual battery options rather than a communal scheme, EnergySage offers information and competitive installation estimates. EnergySage has teamed up with electrification brand Qmerit to help homeowners get the best price on home battery storage solutions.
More background
Social landlord Trivallis has fitted two systems at sheltered housing sites, its decarbonization manager, Clifford Heaven, told Inside Housing.
"The bill savings were immediate; it's reduced bills by up to 50% in a lot of cases," Heaven said.
Many residents are living in inefficient, aging homes — a problem highlighted by Lewisham Council's net-zero carbon manager, Tania Jennings.
Landlords are still considering building improvements, but residents can tackle energy costs in the meantime with solar power and battery storage.
Beyond shared arrangements such as FlatSave, adding appropriately configured battery storage is one of the best ways to protect your home during outages. It can also help save money on energy and provide greater energy independence.
What's being done?
Other social landlords have shown interest in the scheme, Inside Housing reported. For Peabody, planned projects nationwide would build on its first FlatSave installation at Harper Court in Stevenage.
Residents can keep their current electricity supplier when joining; they don't need an E.ON Next account.
Peabody's senior retrofit manager, Rashida Kutubu, said the scheme "distributes energy across every flat based on what each household needs. We're not just reducing bills, we're putting money back in residents' pockets too."
Separate from FlatSave, Pila is another company offering strong battery backup options. Pila's plug-and-play batteries cost a fraction of a whole-home backup system.
