Driving Costs

Fuel is only one part of the real cost of driving. This guide helps you understand the everyday costs that affect UK drivers.

Quick answer

The real cost of driving is fuel plus insurance, vehicle tax, MOT, servicing, tyres, parking, tolls, clean air charges and depreciation. For many drivers, insurance and depreciation can be bigger than fuel.

FuelUsually the most visible day-to-day cost.
InsuranceOften one of the largest yearly costs.
MaintenanceMOT, servicing, tyres, brakes and repairs.
ChargesParking, tolls, ULEZ, CAZ and congestion charges.

The main costs to track

Instead of only looking at the pump price, it is better to understand your total cost per mile. This makes it easier to compare vehicles, journeys and driving habits.

Fuel or electricityPetrol, diesel or EV charging costs change with price, efficiency, mileage and where you fill or charge.
InsuranceYour age, vehicle, postcode, claims history, mileage and parking location can all affect the premium.
Vehicle taxVehicle Excise Duty depends on vehicle type, age, emissions and tax rules. Always check the current rate for your vehicle.
MOT & servicingRegular checks protect safety and can reduce expensive surprise repairs later.
Tyres & brakesWorn tyres and brakes are safety issues, but they are also recurring running costs.
Parking & road chargesCity parking, private car parks, tolls and clean air zones can change the cost of a journey.
DepreciationThe loss in vehicle value is easy to ignore, but it can be one of the biggest long-term costs.

Fuel costs

Fuel cost depends on three things: price per litre, vehicle efficiency and distance. A cheaper station is useful, but the saving can disappear if you drive too far out of your way.

Best number to track

Use pence per mile, not just monthly spend. It shows how much each mile really costs.

Small habits matter

Tyre pressure, smooth driving and removing unnecessary weight can all affect fuel use.

Driverz tip

When comparing stations, consider the return journey cost as well as the pump price.

Insurance costs

Insurance can vary heavily between drivers and vehicles. It is not just about the car; where it is kept, how many miles you drive and your claim history can also matter.

  • Compare quotes before renewal, not after the policy has already rolled over.
  • Check whether annual mileage is realistic.
  • Consider voluntary excess carefully. A higher excess may reduce the premium, but increases what you pay after a claim.
  • Young or new drivers may find telematics policies useful, but they should check the conditions first.

Tax, MOT and servicing

Vehicle tax, MOT and servicing are not daily costs, but they should still be budgeted for. A cheap car can become expensive if it needs frequent repairs or has high tax.

Vehicle tax

Check the current tax class and rate for your exact vehicle before buying.

MOT history

A vehicle with repeated advisories may cost more to keep safe and roadworthy.

Servicing

Regular servicing can protect reliability, fuel efficiency and resale value.

Tyres

Tyres affect safety, braking and fuel economy. Check tread and pressure regularly.

Parking, tolls and city charges

For city drivers, the cost of parking and road charging can be as important as fuel. Some journeys may include parking fees, tolls, congestion charges or clean air zone charges.

  • Check clean air or congestion charges before driving into a city centre.
  • Compare park-and-ride options for longer city visits.
  • Read private parking signs carefully before leaving the vehicle.
  • Remember that airport and event parking can change the total trip cost significantly.

EV running costs

EV running cost depends heavily on where you charge. Home charging is often cheaper than public rapid charging, but public charging can still be useful for long journeys.

Home charging

Usually best for low cost and convenience when you have access to a driveway or home charger.

Public charging

Costs vary by operator, charging speed and location. Rapid chargers are often more expensive.

Efficiency

EV cost per mile depends on miles per kWh, driving speed, weather and charging losses.

Compare fairly

Compare petrol p/mile with EV p/mile rather than only comparing fill-up and top-up totals.

Quick answers

Is fuel the biggest driving cost?

Not always. Insurance and depreciation can be larger, especially for newer or higher-value vehicles.

What is pence per mile?

It is the cost of driving one mile. It is one of the simplest ways to compare real running costs.

Can tyre pressure affect fuel cost?

Yes. Underinflated tyres can increase fuel use and tyre wear.

Are EVs always cheaper to run?

EVs can be cheaper per mile, especially with home charging, but the result depends on electricity price, efficiency and charging habits.
