Every “petrol vs EV” article uses someone else’s car and someone else’s electricity bill. Ours uses your reg, your miles, and whether you charge at home — because that is where the comparison actually lives.
High mileage with cheap overnight electricity — the fuel bill gap compounds every month.
Coming out of a thirsty diesel or an older petrol that drinks on short trips. Pump prices hurt more when the tank is small and you fill it often.
Low mileage, no driveway. You are paying retail for electrons and rarely driving enough to claw back the higher purchase price.
A cheap hybrid you already own outright and plan to keep until it rusts. The EV case is about replacing running costs, not winning a theoretical debate.
