If you're planning to drive across the Dartford Crossing — whether it's part of your daily commute or a one-off trip — you'll need to pay the Dart Charge. Unlike some tolls, you can’t pay as you drive through, and forgetting to pay can result in a hefty fine.
In this guide, we’ll cover what the Dart Charge is, how much it costs, how to pay it, and how to avoid common mistakes that catch drivers out.
The Dart Charge is a toll payment for using the Dartford Crossing, which includes the Queen Elizabeth II Bridge (southbound) and the Dartford Tunnels (northbound) on the M25 motorway. It's a key route for drivers heading between Kent and Essex.
Since 2014, the Dartford Crossing has used an electronic tolling system. That means there are no toll booths — you must pay online, over the phone, or via a Dart Charge account after your journey.
The cost of the Dart Charge depends on your vehicle type. Most cars pay a standard rate, while larger vans and lorries are charged more. Motorcycles can use the crossing free of charge.
Prices can change, so always check the latest rates on the official GOV.UK website.
You have until midnight the day after your journey to pay the Dart Charge. For example, if you crossed at 3pm on a Monday, you need to pay before 11:59pm on Tuesday.
If you don’t pay on time, a Penalty Charge Notice (PCN) will be sent to the registered keeper of the vehicle.
You can pay the Dart Charge in three main ways:
1. Online via GOV.UK
Visit the official payment page at www.gov.uk/pay-dartford-crossing-charge. You’ll need your vehicle registration number and a debit or credit card.
2. Set Up a Dart Charge Account
If you use the crossing regularly, it’s worth creating a Dart Charge account. You can register vehicles, top up your balance, and set up automatic payments. It can also help you save money on each crossing.
3. Pay by Phone
You can call the Dart Charge contact centre on 0300 300 0120 and pay by card. Lines are usually open during office hours.
If you don’t pay the Dart Charge by the deadline, the DVLA will issue a Penalty Charge Notice to the vehicle’s registered keeper. The standard penalty is £70, reduced to £35 if paid within 14 days. If ignored, the fine can rise to £105 and lead to enforcement action.
Many drivers forget to pay simply because they didn’t set a reminder. If you cross the Dartford Crossing even once, it’s worth setting up a system so you never miss a payment.
To avoid penalties, follow these tips:
