Cost to Drive to London UK
Driving to London can look cheap if you only count fuel, but the real cost can change quickly once parking, Congestion Charge, ULEZ, passenger numbers and return mileage are included.
Use this page to estimate your fuel cost, understand the extra London driving charges, and decide whether driving, train, coach or public transport makes more sense for your journey.
The simple answer
The fuel cost of driving to London depends on your starting distance, fuel price and MPG. A 100-mile trip in a 45 MPG petrol car at £1.50 per litre costs about £15 in fuel each way, or about £30 return.
That is not the full cost. If you drive into central London, you may also need to budget for the Congestion Charge, ULEZ if your car is not compliant, parking, tolls, drop-off charges and extra time in traffic.

Extra costs of driving to London
These are the costs that often make driving to London more expensive than the fuel figure suggests.
Applies if you drive inside the central London Congestion Charge zone during charging hours.
Non-compliant vehicles may need to pay a daily charge when driving within the ULEZ area.
Central London parking can be expensive, especially for a full day or weekend visit.
Heavy traffic can reduce MPG and increase the actual fuel cost.
Tyres, brakes, servicing and depreciation still matter on long journeys.
Some routes may involve tolls, river crossings or paid drop-off areas.
London charge checklist before you drive
Check these before deciding that driving is cheaper than the train or coach.
Are you entering central London?
If yes, check whether the Congestion Charge applies to your journey time and destination.
Is your car ULEZ compliant?
If not, add the daily ULEZ charge before comparing driving with public transport.
Where will you park?
Parking can easily cost more than the fuel if you are staying for several hours.
How many people are travelling?
Driving may become cheaper per person when several passengers share the cost.
Driving to London vs train or coach
The cheapest option depends on passenger numbers, parking, journey flexibility and how close your destination is to a station.
