Agile vs Octopus Go
Go gives predictable overnight pricing; Agile gives flexible half-hourly pricing with more variation.
Short answer
Octopus Go can suit predictable overnight use, especially regular EV charging. Agile can be cheaper on some days, but only if you can react to the actual cheap windows. If you mostly want to plug in overnight and not think about it, Go is easier to understand. If you can adapt to the daily price shape, Agile may compare better under some assumptions.
If you want live context while reading, check the dashboard, test a real run in the appliance timer, set a trigger in alerts, or compare the same day across regions.
Predictable vs flexible
Go has a known cheap overnight period plus a day rate. Agile changes every half hour, so cheap periods can move around, become very cheap, or be less useful on some days. Agile gives more flexibility, but it also asks more from the household.
EV charging
EV charging is where Go is easiest to understand. If the car can charge overnight most nights, a predictable cheap rate is valuable. Agile may still look strong on very cheap nights, but Go can be simpler when the charging habit is stable.
Use split mode
A simple average is weak for this comparison because Go depends on how much electricity lands overnight. Use split mode in the compare tool and set a realistic overnight percentage. The result is still an estimate, but it is more useful than assuming all usage is spread evenly.
Example
A 28kWh EV charge is large enough to dominate the comparison. If most of it lands in a cheap Go window, Go can look strong even when Agile has a decent daily average. If Agile has several very cheap overnight slots, the comparison can swing the other way.
What to watch out for
Check the tariff rules before acting. EV tariffs can have eligibility requirements, day rates, off-peak windows, and smart-charging behaviour that affect the real result.

The best washing-machine slot is a cheap usable window, not the single cheapest half-hour.
Best time to charge an EV
EV charging on Agile works best when you can use a long low-cost block away from peak periods.
