| Electricity per mile | ~6.7p | ~6.3p |
Electricity only, at the Ofgem price cap direct-debit average of about 25p/kWh (set nationally; changes quarterly). There are no per-mile road charges in the UK, and both vehicles pay the same standard-rate VED (~£195/yr), so road tax does not change the head-to-head result. EV tariffs with cheap overnight windows can lower the electricity cost; rates vary by supplier.
