Fuel Costs Explained

Fuel is the cost you notice most because you pay for it every week.

• Petrol: Roughly 12–15p per mile at current prices.
• Diesel: Similar cost per mile, but better economy on motorways.
• Electric (home charge): Just 4–6p per mile. Much cheaper.
• Hybrid: Around 8–12p per mile depending on how much you use the electric motor.

You can cut fuel costs by driving smoothly, keeping tyres inflated, and using CarOwl's fuel finder to find the cheapest petrol near you.

Insurance Costs

Insurance is usually the second biggest annual cost after depreciation.

• The average UK premium is around £500–£700 per year.
• Young drivers under 25 pay much more — often £1,000–£2,500+.
• The car you drive matters. Lower insurance groups mean cheaper premiums.
• Where you live matters too. Urban areas cost more than rural ones.

The single best way to save is to never auto-renew. Shop around every year. Most people save £200+ just by comparing quotes.

Servicing and MOT

Regular servicing keeps your car reliable and protects its value.

Service Costs

• Interim/basic service: £100–£200. Oil and filter change plus basic checks.
• Full service: £200–£400. Everything in a basic service plus spark plugs, air filter, brakes check, and more.
• Major service: £300–£600. Done every 2–3 years. Includes everything plus extra items like brake fluid change.

MOT Costs

The maximum MOT fee is £54.85, but many garages charge less. Some offer free MOTs if you book a service at the same time.

Cars need an MOT every year from their third birthday. Check your MOT history to see when yours is due.

Road Tax (Vehicle Excise Duty)

Road tax costs depend on your car's CO2 emissions and when it was first registered.

• Cars registered after April 2017: A flat rate of £180 per year for most petrol and diesel cars.
• Electric cars: Currently pay a reduced rate. Check the latest rates with CarOwl's tax check.
• Cars over £40,000 new: Pay an extra £410 per year for the first 5 years.

You can pay monthly by Direct Debit, but it costs slightly more (about 5% extra).

How to Reduce Your Running Costs

Small changes add up to big savings over a year.

1. Shop around for insurance every year. Never auto-renew. This alone saves £200+ on average.
2. Drive smoothly. Gentle acceleration and braking use less fuel.
3. Keep up with servicing. A well-maintained car uses less fuel and avoids expensive breakdowns.
4. Check tyre pressures monthly. Underinflated tyres increase fuel use by up to 3%.
5. Remove unnecessary weight. Clear out the boot. Extra weight costs fuel.
6. Compare fuel prices. The difference between the cheapest and most expensive petrol station can be 10p per litre.

Are Electric Cars Cheaper to Run?

Yes, significantly. Here's how an EV compares to petrol over 10,000 miles.

Cost	Petrol Car	Electric Car
Fuel/electricity	£1,300	£500
Road tax	£180	£0–£10
Servicing	£300	£100
Total	£1,780	£600–£610

EVs have fewer moving parts, so they need less servicing. No oil changes, no exhaust repairs, no clutch replacements.
