Frequently Asked Questions
Everything you need to know about UK car running costs
What is the average cost of running a car in the UK?
The average annual cost of running a car in the UK is between £3,000 and £5,000, depending on the vehicle type, mileage and driving habits. This includes fuel, insurance, road tax, MOT, servicing, repairs and depreciation. Higher-mileage drivers and those with older vehicles typically pay more.
What are the biggest car expenses for UK drivers?
Depreciation is usually the largest hidden cost, followed by fuel, insurance and repairs. For a typical family car, depreciation accounts for around 40% of total costs, fuel 20-25%, insurance 15%, and servicing plus repairs around 10-15%. Tax and MOT make up the remainder.
How can I reduce my car running costs?
Key ways to reduce running costs include shopping around for insurance at renewal, maintaining correct tyre pressures for better fuel economy, keeping up with regular servicing to prevent costly repairs, driving smoothly to reduce fuel consumption, and considering whether a more fuel-efficient or electric vehicle would save money over time.
How much does fuel cost per mile in the UK?
At current UK fuel prices, a petrol car averaging 40 MPG costs approximately 15-18p per mile in fuel alone. Diesel vehicles averaging 50 MPG cost around 13-16p per mile. Electric vehicles are significantly cheaper at approximately 4-6p per mile depending on your electricity tariff and charging habits.
How much does car insurance cost on average in the UK?
The average UK car insurance premium is approximately £800-900 per year for comprehensive cover, though this varies enormously based on age, location, driving history, vehicle type and annual mileage. Young drivers and those in urban areas typically pay significantly more.
Is it cheaper to run an electric car in the UK?
Electric vehicles are generally cheaper to run day-to-day. Electricity costs around 4-6p per mile compared to 15-18p for petrol. EVs also benefit from zero road tax (until 2025), lower servicing costs due to fewer moving parts, and exemption from congestion charges. However, the higher purchase price means total cost of ownership depends on mileage and how long you keep the vehicle.
How do I track my car expenses accurately?
The most effective way is to use a dedicated car expense tracking app like CarFile. Log every expense as it happens — fuel, insurance, tax, MOT, servicing, repairs and parking. Over time you will build an accurate picture of your true running costs and identify areas where you can save money.
The True Cost of Running a Car in the UK
Breaking down UK car ownership costs
Running a car in the UK involves far more than just filling up with fuel. The average UK driver spends between £3,000 and £5,000 per year on their vehicle when all costs are accounted for. The biggest expense is often one that most people overlook entirely: depreciation. A new car can lose 50-60% of its value in the first three years, which for a typical family car amounts to several thousand pounds per year in lost value.
Fuel is the most visible running cost, typically accounting for 20-25% of total annual expenses. At current UK fuel prices, a petrol car averaging 40 MPG driven 8,000 miles per year will cost around £1,200-1,500 in fuel. Diesel vehicles tend to be more fuel-efficient but carry a higher purchase price. Electric vehicles offer the lowest per-mile fuel costs at roughly 4-6p per mile, compared to 15-18p for petrol.
Insurance is another major expense, with the average UK premium sitting around £800-900 for comprehensive cover. Young drivers, new drivers and those in high-crime areas often pay significantly more. Shopping around at renewal rather than auto-renewing is one of the simplest ways to reduce this cost — savings of £200 or more are common.
How to reduce your car running costs
The first step to reducing costs is understanding where your money goes. Many drivers are surprised by how much they spend on their vehicle once they start tracking every expense. CarFile makes this easy by letting you log fuel, insurance, tax, MOT, servicing and repairs in one place — then showing you a clear breakdown of costs by category over any time period.
Regular servicing is one of the most effective ways to prevent expensive repairs. A missed oil change can lead to engine damage costing thousands. Maintaining correct tyre pressures improves fuel economy by up to 3%. Driving smoothly — avoiding harsh acceleration and late braking — can reduce fuel consumption by 15-20% compared to aggressive driving styles.
For those considering their next vehicle, total cost of ownership is more important than purchase price alone. A cheaper car with poor fuel economy and high insurance costs may end up costing more than a slightly more expensive but more efficient alternative. CarFile's expense tracking helps you build the data you need to make informed decisions about keeping, replacing or upgrading your vehicle.
