Is Intelligent Octopus Go worth it for low-mileage drivers?
How to tell whether Intelligent Octopus Go saves money if you do not drive much, and when a standard tariff is cheaper.
Edited by Rob Gibbs. Published: . Guidance reviewed: .
Short answer
Intelligent Go trades a cheap overnight rate for a higher day rate. With low mileage, the car moves few kWh into the cheap window, so the saving depends mostly on how much other household use happens overnight. If most of your use is in the daytime, a standard tariff can work out cheaper.
The break-even in plain terms
Each kWh in the cheap window saves you the gap between the standard rate and the off-peak rate. Each kWh used during the day costs you the gap between the day rate and the standard rate. Intelligent Go wins when the first total is bigger than the second.
Ways to tip it in your favour
Overnight use outside the car counts too:
- Run the dishwasher and washing machine on timers after 23:30.
- Heat a hot-water tank overnight.
- Charge a home battery overnight and use it during the day.
Check with real numbers
Compare your region’s Intelligent Go and Flexible rates, then price your own half-hourly usage on both with the usage tools.
