Defaults: real-world EV efficiency 3.2 mi/kWh; petrol economy 45 mpg. Prices used in the June 2026 edition: average UK unleaded 158.0p/litre and diesel 181.8p/litre (DESNZ weekly road fuel prices, w/c 8 June 2026); public charging 54p/kWh (fast) and 79p/kWh (rapid/ultra-rapid) PAYG weighted averages (Zapmap price index, May 2026); standard home rate 26.32p/kWh (Ofgem price cap, Oct–Dec 2026, confirmed 26 August 2026; Jul–Sep rate 26.11p); off-peak EV tariff 7p/kWh (typical six-hour overnight EV tariff window; some 2026 tariffs are as low as 3.5–5.5p).
