Owning and running a car in the UK costs more than most drivers realise. Beyond the purchase price or finance payment, the true annual running cost — fuel, insurance, road tax, MOT, servicing, and depreciation — averages £4,000–£6,000 per year for a typical family car. Understanding all the costs before buying helps avoid a vehicle that erodes your budget every month. This hub covers the full picture: running costs, finance options, reducing expenses, and the electric vs petrol decision.

Worked example — true cost of a PCP deal
Sarah sees a car advertised at £299/month PCP, 36 months, 8,000 miles/year.
| Cost element | Amount |
|---|---|
| Monthly PCP payments (36 months) | £299 × 36 = £10,764 |
| Deposit (required) | £2,000 |
| Final balloon payment | £8,500 |
| Total paid if keeping the car | £21,264 |
| Car’s list price | £18,000 |
| Total credit cost | £3,264 |
Running costs on top: at 8,000 miles/year, Sarah also spends ~£4,000/year on fuel, insurance, and VED — £12,000 over 3 years.
Total 3-year cost of this car: approximately £33,000 — versus the £10,764 headline figure she saw advertised.
Understanding the full picture prevents budget surprises.

When to consider scrapping or replacing your car
An older car can feel “paid for” but become costly. Warning signs that running costs are exceeding the car’s value:
- Annual repair bills exceed 25% of the car’s market value
- MOT advisories are turning into failures year-on-year
- Fuel economy has deteriorated significantly
- Insurance costs for an older car exceed the car’s replacement cost
Use a site like Motorway.co.uk or We Buy Any Car to check your car’s current market value. If repair costs this year exceed £1,500 on a car worth £3,000, replacing often makes more financial sense than repairing.
The hidden cost of a very old car: no in-built safety technology, higher insurance group for some models, and potential ULEZ charges in city centres (currently London; other cities have clean air zones with different rules).
