EV charging is the big case
Go is worth comparing when there is regular EV charging. A car charge is large enough to dominate the electricity bill, so a reliable overnight window can be valuable.
Agile can still come out cheaper on some days, especially when there are several low-price slots. The trade-off is effort: check the shape, set the charge window, or automate around the published prices.
Why a daily average is weak here
A daily Agile average does not tell you whether it beats Go for EV charging.
A 28kWh charge placed into a cheap overnight Go window is very different from the same 28kWh spread across expensive Agile slots. The comparison depends on the actual charge time and how much household use lands outside that window.
Who may prefer Go
Go may be the better practical fit when:
- the EV can charge overnight most nights
- predictability matters
- nobody wants to check tomorrow's prices
- the car needs a reliable routine
- the household is less flexible outside EV charging
Who may prefer Agile
Agile may be worth testing when:
- charging can move around
- you have a battery as well as an EV
- you can avoid peak slots reliably
- alerts or automation can handle the timing
- you are comfortable with some days being better than others
Practical check
Use the Compare page in split mode. Set a realistic overnight share, especially if the EV uses a lot of electricity.
Then use the Appliance timer with an EV preset and a real finish time. The useful question is not just whether Agile is cheaper today. It is whether there is a long enough cheap block that works for the car.
