Octopus Intelligent vs Octopus Go: which is better?

Intelligent: 7.5p overnight + smart slots + EV-integrated scheduling. Requires compatible EV. Go: 7.5p overnight (fixed window), works with any EV and any charger. If your EV is compatible: Intelligent is better (extra smart slots). If not: Go is excellent.

Can I use Intelligent with a non-smart charger?

Yes — but you lose the smart slot benefits. The 7.5p overnight rate still applies. For maximum benefit: use a smart charger (Ohme, Zappi) or a compatible EV with built-in scheduling.

Does the 7.5p rate apply to my whole house overnight?

Yes — the 23:30-05:30 rate covers ALL electricity use, not just EV charging. Run your dishwasher, charge your battery, heat water — all at 7.5p overnight.

Is Octopus Intelligent good with solar?

Octopus Intelligent Go: a smart EV tariff that works brilliantly with solar. HOW IT WORKS: 7.5p/kWh overnight (23:30-05:30 guaranteed, plus 'smart slots' throughout the day). 24.5p/kWh daytime. Your car connects to Octopus via their app — it schedules charging to cheapest slots. WITH SOLAR: charge from solar during the day (FREE), top up from cheap overnight rate (7.5p). Combined strategy: £0-£100/yr total EV running cost (vs £1,500-£2,500 petrol). WITH BATTERY: charge battery from 7.5p overnight, use stored energy during expensive daytime (saves 17p/kWh difference). Battery savings: extra £200-£400/yr. ELIGIBLE CARS: Tesla, VW ID range, Hyundai, Kia, BMW, and others with smart charging capability.
