Eligibility needs checking
- Battery control
- Octopus controls compatible battery
- Off-peak / import
- Temporarily unavailable · restricted eligibility · Supplier optimised
- Export
- Supplier optimised
Octopus's live page again states that Intelligent Octopus Flux is temporarily unavailable. The same page remains internally inconsistent: its eligibility section says compatible solar and battery equipment need not have been installed by Octopus, while a separate notice says the tariff is currently exclusive to customers who bought both from Octopus. Battery Boost therefore treats the tariff as paused and restricted until Octopus publishes a consistent reopening route.
BETATenant Power
Eligibility needs checking
- Battery control
- Octopus controls approved battery
- Off-peak / import
- Landlord-agreed discount vs Flexible Octopus · Continuous discounted unit rate
- Export
- Not publicly stated
Octopus's published terms confirm a restricted landlord-linked proposition rather than a generally quoted retail tariff. The electricity discount is agreed with the landlord and varies with the Ofgem price cap; the regional Flexible Octopus standing charge remains. No public unit rate, export payment or open sign-up route is stated, so eligibility and price must be confirmed directly.
ACTIVEOutgoing Octopus
No device-specific integration required
- Battery control
- No battery control
- Off-peak / import
- Not applicable · Flat export
- Export
- 12p/kWh (variable)
Requires Octopus import supply and an eligible pairing. Half-hourly export data and an export MPAN are needed; switching from FIT export can involve restrictions.

Other batteries can join in self-optimise mode, subject to eligibility. The first-1,000 booster discounts overnight imports and boosts peak exports by 3p/kWh for 12 months; it is not a 3p unit price. Availability of the booster must be confirmed.

- Battery control
- Customer schedules battery
- Off-peak / import
- Quote-only off-peak price · 02:00–05:00
- Export
- Separate export tariff
Current terms describe a 12-month fixed tariff with one lower-priced 02:00–05:00 window, a standard rate at other times and no exit fee. E.ON does not publish general unit rates on the cited page, so the personalised quote is decisive. The terms do not promise supplier battery control; customers should confirm equipment, export pairing and scheduling separately.

We do not have sufficiently specific expansion data for this exact record, so no maximum capacity or compatible battery is being inferred.
