Intelligent Octopus Go EV Tariff Review
Octopus Energy's flagship EV tariff: six off-peak hours at ~8p/kWh whole-home (23:30–05:30), with the new 6-hour cap and Charge Cap toggle from March 2026.
4.5 / 5
☆☆☆☆☆
★★★★★
Pros
- Off-peak rate around 8p/kWh — among the cheapest in the UK as of May 2026
- Cheap rate applies to your whole home during the 6-hour window, not just the EV
- Works with Ohme, Andersen, Wallbox, Hypervolt, Zappi and Octopus Charge
- Intelligent scheduling can add bonus cheap slots during the day when grid supply is high
- No exit fees on the variable Intelligent Octopus Go product
Cons
- From March 2026 only the first 6 hours of nightly charging are at the off-peak rate; further charging falls back to the higher Boost rate
- Requires an SMETS2 (or compatible SMETS1) smart meter and a smart EV charger that supports Octopus's intelligent scheduling
- Daytime/peak rate of around 32p/kWh is unremarkable — the savings rely on shifting most usage to overnight
- Customers report occasional billing-accuracy issues on overnight sessions that need manual support to resolve
