Prioritises simplicity
Prefer the structure needing less repeated intervention.
Agile requires attention or automation. Flexible does not reward moving use within the day.

Agile vs Flexible Octopus
Choose between active price shifting and a simpler rate structure.
Edited by Rob Gibbs. Guidance reviewed: .
Overall verdict
Choose between active price shifting and a simpler rate structure. There is no universal winner: use the measured evidence window, then test the result against your own consumption, equipment and current eligibility.
Historic profile evidence
Region: London. Profile: Typical household. Evidence window: 2026-08-01 to 2026-08-31.
Historic profile-weighted evidence, not a bill, forecast or switching quote. Standing charges remain separate.
Agile Octopus
27.16 p/kWh profile-weighted unit rate
39.54 p/day standing charge
2,700 kWh annual scenario: £877.58
Flexible Octopus
26.35 p/kWh profile-weighted unit rate
41.50 p/day standing charge
2,700 kWh annual scenario: £862.84
The annual scenario applies each historic weighted unit rate to 2,700 kWh and adds 365 daily standing charges. It is illustrative, not a forecast or personal bill.
On this evidence window and profile, flexible had the lower weighted import unit rate. That is not a forecast or universal winner.
Which household does each structure fit?
Can shift or automate
Give more weight to the option that rewards controllable timing.
Agile changes every half hour; Flexible is variable but not half-hourly.
Has specialist equipment
Check the equipment-led option only after exact compatibility is confirmed.
Agile needs suitable half-hourly smart-meter operation; Flexible has no scheduling equipment requirement.
Full feature comparison
| Feature | What differs |
|---|---|
| Equipment | Agile needs suitable half-hourly smart-meter operation; Flexible has no scheduling equipment requirement. |
| Eligibility | Confirm the current product and meter arrangements in the supplier quote. |
| Effort and automation | Agile requires attention or automation. Flexible does not reward moving use within the day. |
| Price variability | Agile changes every half hour; Flexible is variable but not half-hourly. |
| Import/export pairing | Check export pairing separately. |
Equipment
Agile needs suitable half-hourly smart-meter operation; Flexible has no scheduling equipment requirement.
Eligibility
Confirm the current product and meter arrangements in the supplier quote.
Household effort
Agile requires attention or automation. Flexible does not reward moving use within the day.
Price risk
Agile changes every half hour; Flexible is variable but not half-hourly.
Import and export pairing
Check export pairing separately.
Standing-charge treatment
The historic evidence displays standing charges separately. A lower profile-weighted unit rate is not a lower annual bill unless daily charges and annual kWh are also included.
Seasonality
One complete month can differ from a trailing year. Heating, solar generation, EV mileage and wholesale conditions can all move with the season, so the evidence is not a forecast.
Break-even limits
A meaningful break-even needs comparable unit rates, standing charges and one explicit annual-use profile over the same evidence window. Half-hourly or daily rates and household timing vary; one static unit-rate crossing would imply precision the evidence does not have.
When the answer could change
- Your annual kWh or half-hourly usage shape changes.
- Current product versions, prices or standing charges change.
- Equipment compatibility or supplier eligibility changes.
- A different season changes heating, driving, generation or export.
Questions people ask
Does Agile vs Flexible Octopus have one winner?
No. The page separates measured historic evidence from household-specific constraints and does not predict future prices.
Does the ranking include a full bill?
No. The unit-rate evidence and standing charge are shown separately; other bill adjustments and future rates are excluded.
Can the result change after I switch?
Yes. Rates, seasons, usage, product terms, device support and meter performance can all change.
