Factors that affect running costs
Depreciation
The biggest single cost for most cars. New cars lose 40–60% of value in 3 years. Buying a well-depreciated 2–3 year old car is the most effective way to reduce total ownership cost.
Fuel and energy
At 10,000 miles/year, fuel costs typically range from £600–£1,500/year for petrol/diesel, versus £200–£400/year for home-charged EVs. Public charging can significantly increase EV costs if used regularly.
Insurance
Varies enormously by driver age, location and car model. Shop around every year — the savings are real.
Servicing
EVs require less frequent servicing with no oil changes and longer brake pad life (regenerative braking). Budget £150–£250/year for an EV versus £350–£500/year for a comparable petrol car.
