How much does it cost to charge a Jaguar I-Pace at home?
A full home charge of the Jaguar I-Pace EV400 (2018-2024) costs about £25.13 at the July 2026 Ofgem price cap (26.11p/kWh) — that is 8.7p per mile. The typical 20–80% top-up costs £15.08.

Costs include the ~12% energy lost during AC charging, so they reflect what your meter records. Off-peak rates assume all charging happens inside the cheap window — how much of your charging has to land in it decides whether an EV tariff pays. Rates vary by region. These are comparisons of published rates, not tariff recommendations.

Charging time by charger type
Most owners choose between a 7 kW wallbox and the socket they already have. A three-pin plug costs nothing to install but charges at about 2.3 kW, which is the difference between an overnight top-up and a two-day one on this car’s 84.7kWh pack. Charging away from home is a different calculation again — public rapid rates run several times higher.
| Charger | Speed for this car | 20–80% | Empty to full |
|---|---|---|---|
| Three-pin plug (2.3 kW) | 2.3 kW | 22 hr 6 min | 36 hr 50 min |
| 3.6 kW wallbox | 3.6 kW | 14 hr 7 min | 23 hr 32 min |
| 7 kW wallbox | 7 kW | 7 hr 16 min | 12 hr 6 min |
| 22 kW three-phase | 7.4 kWlimited by the car | 6 hr 52 min | 11 hr 27 min |
Times are simple energy-needed ÷ power estimates. Real sessions can run a little longer, because charging slows as the battery approaches full.
What affects these numbers for the Jaguar I-Pace
This car charges at up to 7.4 kW on AC
The Jaguar I-Pace's onboard charger accepts at most 7.4 kW from an AC connection. A 22 kW three-phase cannot charge it any faster than that, so there is no benefit in paying for a more powerful home charger than the car can use.
A three-pin plug is a backup, not a plan
From a standard three-pin socket (2.3 kW), an empty-to-full charge of the 84.7 kWh battery takes about 36 hr 50 min. Fine for overnight top-ups, but impractical as your only way to charge.
Efficiency is below the EV average
At 3.4 miles per kWh, the Jaguar I-Pace uses more electricity per mile than most EVs, so each mile costs a little more even on the same tariff.
Real-world figures vary
The 292-mile range is the official WLTP lab figure. Cold weather and motorway speeds reduce real-world efficiency, which raises cost per mile and lowers range. Treat these numbers as good estimates, not promises.
The 104 kW DC figure is not for home charging
DC rapid charging at up to 104 kW only happens at public rapid chargers. All home charging is AC, so it is the 7.4 kW AC limit that matters for the times on this page.
