Watt-hours per mile are each model’s EV-Database real-range vehicle consumption. Miles per kWh is 1,000 ÷ that figure, to two decimal places. Yearly energy is miles ÷ mi/kWh. Each cost is rounded to the nearest pound. The saving is the rounded standard cost minus the rounded off-peak cost, so it is a range too. Most figures are estimates for moderate driving and climate. These pages are not marked that way: Tesla Model 3 RWD, Hyundai Kona Electric 65 kWh, BYD Atto 3, Fiat 500e, Fiat 600e, Citroën ë-C3, Hyundai Ioniq 6, BMW iX3 and Kia EV5 81.4 kWh. Cold weather and motorway speeds use more. The 54.83p/day standing charge is excluded because it does not change with the unit rate.
Kia Niro EV, Jaguar I-Pace, Mercedes EQA and EQB, Volvo EX40 and EC40, Audi Q8 e-tron, Zeekr, BYD Seal U, Honda e:Ny1, Lexus UX, Lancia, MG5 and Firefly are not on the current EV-Database UK consumption list, so they are not here. Tesla no longer lists a Model 3 or Model Y called Long Range. The Premium, Performance and AWD versions are the ones on that list.
On Intelligent Octopus Go the cheap window covers the whole home, so a dishwasher, a wash or an immersion heater moved into 23:30–05:30 is cheap too. The daytime rate is higher than the cap and is a quote for your address. Octopus does not publish one national peak figure.
The tariff sets the off-peak rate, not the wallbox. For other loads in the cheap window, the homepage features the EcoFlow RIVER 2 Pro (paid link).
