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 £1.60 per litre costs about £16 in fuel each way, or about £32 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.
£18 a day if paid on the day or in advance, rising to £21 if paid within 3 days after. Registered electric vehicles on Auto Pay get a 25% discount, paying £13.50.
£12.50 a day for non-compliant vehicles, entirely separate from the Congestion Charge. A non-compliant car driving into central London during charging hours pays both – £30.50 a day combined. Electric vehicles are exempt from ULEZ indefinitely.
Walk-up NCP rates in central London can run to around £50 a day, but pre-booking through an app often brings that down to £12-£15 – one of the widest gaps between gate and pre-booked rates of any UK city.
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?
The Congestion Charge is £18 a day (£21 if paid within 3 days after) – check the zone map and charging hours before you set off.
Is your car ULEZ compliant?
If not, add £12.50 a day – and if you’re also entering the Congestion Charge zone, that’s £30.50 a day combined before parking.
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.
The real cost of driving in
Up to £30.50/day before parking
A non-compliant vehicle entering central London pays £18 Congestion Charge plus £12.50 ULEZ – £30.50 before a single minute of parking. Compliant and electric vehicles avoid ULEZ entirely, and EVs get 25% off the Congestion Charge on Auto Pay.
When driving still wins
- Several passengers genuinely share the £30.50+ charges and parking
- Your destination is outside the charging zones
- You have heavy luggage, tools or equipment
- You drive an electric or ULEZ-compliant vehicle
- You can pre-book parking at £12-15/day rather than the £50 walk-up rate

Return cost
Usually the number you need for a day trip, weekend visit or airport drop-off.
