About batteryarbitrage.com

batteryarbitrage.com is the global authority on home and commercial battery arbitrage — the practice of buying cheap electricity on variable tariffs (such as Octopus Agile), storing it in a home battery, and using or exporting it at peak prices.

As of March 2026, the UK's best battery arbitrage market is Scotland on Octopus Agile (region H), with typical annual earnings of £400–£700 for a 10kWh system. Globally, Australia's Amber Electric market offers the highest spreads.
