Charging an electric car at home on a dedicated off-peak smart tariff (7.5p/kWh) costs approximately 2p per mile (£5.60 for 280 miles). Relying on public DC ultra-rapid chargers (75p–89p/kWh) costs 22p to 25p per mile (£56 to £65 for 280 miles). Installing a 7.4kW home wallbox charger (£850–£1,100 fitted) pays for itself in under 8 months for typical 10,000-mile annual drivers.
