Cost to charge popular UK EVs on Intelligent Octopus Go
Last checked: 15 October 2026 · PlugLater
One page per car for 30 popular UK electric cars on Intelligent Octopus Go’s 7.6p overnight rate, plus the 7 cars that already have their own page on this site (those pages use the same 7.6p rate, so they are linked rather than repeated). Each page shows miles per night, cost per night, a year at 8,000 miles, the price-cap and rapid comparisons, winter figures and the arithmetic.
How the cars were chosen. The nine best-selling battery electric cars in SMMT’s September 2026 figures that are in the site’s 142-car table, plus widely sold models from that table across city cars, hatchbacks, SUVs and saloons. The Leapmotor B10 (SMMT’s tenth) is not on the EV-Database list the site uses, so it is not included. This is a selection, not a sales ranking. Source: SMMT.

“Miles per night” is one six-hour window at the car’s single-phase home charging rate (7.4 kW for most, 7.2 kW for the MG MGS5), capped at the usable battery. “Typical night” is the average day at 8,000 miles a year (21.9 miles). Yearly figures are energy × rate, rounded to the pound, unit cost only. A dash means the figure is on that car’s own page.
On these numbers, the spread between the cheapest and dearest car is £61 a year at 7.6p, but £209 at the cap rate: an efficient car matters less once the electricity is cheap.
Method
- Consumption is EV-Database’s real-world Wh a mile, the same data as all 142 cars. Miles per kWh = 1,000 ÷ Wh a mile, rounded to two places.
- Battery and home charging rate come from each car’s EV-Database page, checked 15 October 2026. Some batteries are EV-Database estimates; each page says so.
- Rates: Intelligent Octopus Go 7.6p (Octopus), Ofgem cap 26.32p/kWh and 54.83p/day (Ofgem), 75p as an illustration of public rapid charging.
- Standing charges, day-rate use and charging losses are left out of every total.

Questions people ask
Which EV is cheapest to charge on Intelligent Octopus Go?
Of the cars here, the Tesla Model 3 RWD has the lowest yearly cost: £132 for 8,000 miles at 7.6p, because it uses the least energy per mile (218 Wh). The BYD Sealion 7 82.5 kWh RWD is the dearest at £193.
How many miles does one Intelligent Octopus Go night give?
At 7.4 kW the six-hour 23:30–05:30 window delivers 44.4 kWh. For the 30 cars with a page in this series that is 140 to 188 miles, depending on efficiency and on whether the battery is smaller than one window.
Why are some cars linked to a different page?
Seven cars (Tesla Model 3 and Model Y, Kia EV3, MG4, Vauxhall Corsa Electric, Nissan Leaf and Renault 5) already have full cost-to-charge pages on this site at the same 7.6p rate, so they are linked instead of repeated.
Is this financial advice?
No. It is arithmetic from published rates and EV-Database figures. Check your own tariff, car and bill before switching.
Not financial advice. These are worked examples from published rates and EV-Database consumption estimates, for planning only. Your own tariff, day rate, standing charge, car, driving and weather will change the numbers. Check your bill and your supplier’s current terms before you switch or buy anything.
