Octopus Charge Pack: the home battery add-on explained
What Octopus Charge Pack does with your home battery, which tariffs and batteries it works with, what you earn and who should skip it.
Edited by Rob Gibbs. Published: . Guidance reviewed: .
Short answer
Charge Pack is an add-on, not a tariff. Octopus takes control of a compatible home battery, charges it when power is cheap and runs your home from it at the day rate. It also uses the battery in grid-support sessions and guarantees at least £12 a month in credit. You need Intelligent Go, Go, Flexible or Fixed for import, Outgoing Octopus for export, a smart meter and a supported battery.
What Octopus does with your battery
Day to day, Octopus schedules the battery to fill up on your cheap overnight rate or spare solar, then discharge when your day rate applies. You keep your existing import and export tariffs.
Occasionally Octopus runs a grid session and tells the battery to charge or discharge to help balance the network. Octopus aims to give up to a day’s notice and says sessions will never leave you out of pocket. Battery imports are compensated down to your off-peak rate, and exports at the difference between your day rate and your export rate.
What you need
Charge Pack currently requires all of these:
- Import: Intelligent Octopus Go, Octopus Go, Flexible or a Fixed tariff. Cosy customers can only register interest for now.
- Export: Outgoing Octopus.
- A working smart meter.
- A supported battery. At the time of writing these are AlphaESS, EcoFlow, Enphase, FoxESS, GivEnergy, HanchuESS, Huawei, Sigenergy and SolarEdge, with more brands listed as coming soon.
The trade-off
You hand battery control to Octopus, and you are automatically opted into every session. Charge Pack also cannot be combined with another company’s battery optimisation service. If you already tune your battery’s schedule closely yourself, compare what you earn now with the guaranteed minimum before you join.
Charge Pack or Flux?
Flux and Intelligent Flux are complete tariffs built around a battery, with their own import and export prices. Charge Pack sits on top of your existing tariff. If you are on Intelligent Go for an EV, Charge Pack lets the battery earn without giving that tariff up.
