How We Compared These Batteries
We evaluated every home battery sold in the UK on seven criteria: installed price, £/kWh value, warranty length, real-world cycle life, inverter compatibility, UK installer network density, and feature set (backup, smart-tariff integration, solar coupling). Capacity figures are usable kWh, not nameplate. Prices reflect installer quotes gathered Q1 2026 from UK MCS-certified installers covering England, Scotland and Wales.
We exclude batteries without UK warranty support, batteries discontinued by the manufacturer, and any product where we couldn't independently verify pricing. The seven below survived. Jump to the comparison table.

How to Choose the Right Battery for Your Home
Choosing a home battery depends on four factors: your budget, whether you have solar panels, your electricity usage, and your property type.
If you have solar panels
A 9–10 kWh battery pairs well with a 4–6 kW solar system. It stores excess daytime generation for evening use, boosting self-consumption from ~35% to ~75%.
Our pick: GivEnergy All-in-One 9.5 kWh
If you don't have solar
Use a battery for tariff arbitrage — charge at 7p/kWh off-peak, use at 28p/kWh peak. The EcoFlow Delta Pro Ultra needs no installation and is ideal for renters.
Our pick: EcoFlow Delta Pro Ultra
If you want maximum capacity
The Tesla Powerwall 3 offers 13.5kWh in a single unit — enough for large homes, EV owners, or those wanting full backup power during outages.
Our pick: Tesla Powerwall 3
If you're on a budget
The Fox ESS EC4100 starts at £4,000 installed for the 8 kWh Master + Slave config, and you can stack up to 28 kWh later. Sunsynk 5.12 kWh is a close runner-up at £3,500–£5,000.
Our pick: Fox ESS EC4100 8 kWh
Best Solar Batteries UK: Which to Pair With Panels
If you already have solar panels — or you're installing them alongside a battery — three of the seven batteries above are purpose-built for solar pairing. Each captures excess daytime generation and discharges through your evening peak, lifting self-consumption from ~35% to 75-80%.
DC-coupled, single unit
Tesla Powerwall 3
Built-in solar inverter (up to 20 kW PV input) and backup gateway. Best for new solar+battery installs from scratch.
All-in-one hybrid
GivEnergy All-in-One 9.5
Integrated 6 kW hybrid inverter handles PV and battery in one box. UK-supported, 12-year warranty. Best for solar systems in the 4-6 kW range.
AC-coupled retrofit
Sunsynk 5.12 kWh
Retrofits to any existing solar system without replacing your inverter. Best value per kWh for solar owners adding storage later.
Pairing a battery with solar takes self-consumption from ~35% to 75-80%, saving an extra £400-£700/year on top of solar-only savings. See our best solar panels guide if you haven't installed panels yet, or our savings calculator to model your specific setup.

Important: Grid Connection Requirements
Most home batteries exceed the 3.68kW threshold, which means they need a G99 grid connection application through your local DNO. Your installer handles this, but it adds 45–65 working days to the timeline.
