Prioritises simplicity
Prefer the structure needing less repeated intervention.
Go is easier to schedule; Agile can reward more active timing decisions.

Agile vs Go
Choose between changing daily opportunities and a predictable overnight window.
Edited by Rob Gibbs. Guidance reviewed: .
Overall verdict
Choose between changing daily opportunities and a predictable overnight window. 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
Octopus Go
28.16 p/kWh profile-weighted unit rate
44.12 p/day standing charge
2,700 kWh annual scenario: £921.28
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, agile 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 half-hourly. Go has defined bands but its product prices and versions can change.
Has specialist equipment
Check the equipment-led option only after exact compatibility is confirmed.
Go is designed for eligible home EV charging; Agile does not verify a vehicle or charger.

| Feature | What differs |
|---|---|
| Equipment | Go is designed for eligible home EV charging; Agile does not verify a vehicle or charger. |
| Eligibility | Confirm EV eligibility for Go and smart-meter suitability for either tariff. |
| Effort and automation | Go is easier to schedule; Agile can reward more active timing decisions. |
| Price variability | Agile changes half-hourly. Go has defined bands but its product prices and versions can change. |
| Import/export pairing | Export compatibility must be checked separately. |
Equipment
Go is designed for eligible home EV charging; Agile does not verify a vehicle or charger.
Eligibility
Confirm EV eligibility for Go and smart-meter suitability for either tariff.
Household effort
Go is easier to schedule; Agile can reward more active timing decisions.
Price risk
Agile changes half-hourly. Go has defined bands but its product prices and versions can change.
Import and export pairing
Export compatibility must be checked 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 Go 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.
