- The 2.5kWh battery plugs into a standard socket with optional solar panels.

Fuse Energy has opened reservations for Jules, a £799 home battery that plugs into a standard UK socket. The company announced the product, which it developed under the working name Bluejay, in a post shared by Co-Founder and CEO Alan Chang.
Chang worked as an early employee and chief revenue officer at Revolut before leaving in 2022 to co-found Fuse with fellow Revolut alumnus Charles Orr.
In a post on Twitter, he explained that Jules holds 2.5kWh of energy and needs no electrician, scaffolding or hardwiring to set up.
Customers can add up to four 500W “Anywhere Panels” on a balcony, wall or in a garden, and Fuse said it would install the panels for free. The battery can also run on its own without any panels attached.
Fuse said Jules uses smart meter data, solar production forecasts and electricity prices to charge when power is cheap and discharge when it is expensive. The company claimed this could save households up to £330 a year.
Fuse listed the following prices for the system:
- £799 for the battery outright
- From £199 for the battery with a five-year fixed tariff from Fuse, with bigger discounts for longer fixes and more panels
- Around £189 for each Anywhere Panel
Fuse backs the battery with a 10-year warranty that it handles directly.
Reservations are open now on Fuse’s website, with deliveries expected in 2027 and existing Fuse customers first in line.
Fuse aims Jules at renters and households that lack a suitable roof or the £8,000 a traditional solar and battery system can cost.
Current UK rules for plug-in solar treat these devices as microgenerators that do not charge a battery from the grid.
Jules still needs further regulatory approval and a safety study before it can charge from the grid, and Fuse set its 2027 delivery target on that basis.
Fuse owns solar farms and other generation assets, runs its own energy trading and supplies electricity and gas to hundreds of thousands of UK homes.
Jules will compete with plug-in battery products from EcoFlow and Anker that UK shoppers can already buy.
