What Dart Charge Is
Dart Charge is a toll system operated by Highways England that charges vehicles for using the Dartford Crossing, a bridge and tunnel that spans the River Thames between Essex and Kent. Instead of stopping at a booth to pay cash, drivers pay electronically — either before they cross, on the day they cross, or within a set window after crossing. The charge varies by vehicle type and time of day.
The crossing itself has been in operation since 1963, but the electronic charging system replaced traditional toll booths in 2014. This means there is no physical place to stop and pay; payment happens through a registered account, a one-time online transaction, or an automatic charge to a vehicle registered with the system.
If you drive the crossing regularly, you can set up a pre-registered account that charges you automatically. If you cross occasionally, you can pay online before or after your journey. If you do neither, you will receive a Penalty Charge Notice — a fine that starts at £70 and can rise to £130 if unpaid.
Key Takeaways
- Dart Charge covers the Dartford Crossing between Essex and Kent, and payment is electronic only — there are no cash booths.
- You can pay before crossing, on the day of crossing, or within ten days after crossing; payment windows vary by account type.
- Registered account holders pay lower rates and can set up automatic charging, while occasional users pay a higher one-time rate.
- Failing to pay within the allowed window results in a Penalty Charge Notice starting at £70, which increases if left unpaid.
- Heavy goods vehicles, buses, and motorcycles pay different rates than cars, and some vehicles may be exempt or discounted.
How Much You Pay and When
The charge depends on what you drive and when you cross. Cars pay one rate, vans and minibuses pay another, and heavy goods vehicles pay a third. The system also offers discounts for off-peak crossings — typically between 10 p.m. and 6 a.m. — which cost less than peak-time crossings.
If you have a registered Dart Charge account, you pay a lower rate per crossing and can set up automatic payments. Occasional users who pay online without an account pay a higher one-time rate. The exact amounts change periodically, so checking the official Dart Charge website before you travel is the most reliable way to know what you will owe.
Some vehicles are exempt or discounted: disabled badge holders, certain emergency vehicles, and some historic vehicles may not pay or may pay a reduced rate. If you think your vehicle qualifies, you can register for a discount or exemption through your account.
Three Ways to Pay
The first option is to set up a pre-registered account. You provide your vehicle registration, payment method, and contact details. Once active, the system automatically charges you each time you cross. This method offers the lowest per-crossing rate and is best if you use the crossing more than a few times per year. You can also set spending limits and receive notifications for each crossing.
The second option is to pay online before or after crossing without registering an account. You visit the Dart Charge website, enter your vehicle registration, and pay by debit or credit card. You have until midnight on the day of crossing to pay, or up to ten days after if you pay after crossing. This method costs more per crossing than a registered account but requires no ongoing commitment.
The third option is to do nothing, which results in a fine. If you do not pay within ten days of crossing, Highways England sends a Penalty Charge Notice to the registered keeper of the vehicle. The initial penalty is £70. If you do not pay that within 28 days, it rises to £130. You can appeal a penalty if you believe it was issued in error, but you must do so within 28 days of receiving the notice.
Setting Up a Registered Account
To open a Dart Charge account, visit the official Dart Charge website and select the option to register. You will need your vehicle registration number, a valid payment method (debit or credit card), and an email address. The process takes about ten minutes and is free to set up.
Once your account is active, you can add multiple vehicles if you own more than one. You can also set a monthly spending cap, which pauses charging once you reach it — useful if you want to control costs. You receive an email receipt after each crossing, and you can view your payment history in your account dashboard at any time.
If you sell your vehicle or no longer need the account, you can close it online. Any credit balance in your account can be refunded to your original payment method, though processing may take several weeks.
What Happens If You Do Not Pay
Crossing without paying and not settling the debt within ten days triggers an automated fine. Highways England issues a Penalty Charge Notice to whoever is registered as the keeper of the vehicle — usually the owner, but sometimes a lease company or fleet operator. The notice includes the original crossing charge, the penalty amount, and instructions for payment or appeal.
If you receive a notice and believe it is wrong — for example, you did pay, or the vehicle was not yours at the time — you can appeal within 28 days. Appeals must be submitted in writing with supporting evidence. Common grounds for appeal include proof of payment, evidence the vehicle was sold before the crossing date, or evidence of a technical fault with the charging system.
If you do not pay or appeal within 28 days, the penalty increases to £130. After that, Highways England can pursue the debt through the courts, which may result in further legal costs and, in rare cases, enforcement action against your bank account or driving license.
Discounts and Exemptions
Disabled badge holders can register for a 50% discount on Dart Charge crossings. To claim this, you must have a valid Blue Badge and register it with your Dart Charge account. The discount applies automatically once your badge is verified.
Some vehicles are fully exempt: certain emergency vehicles (ambulances, fire engines, police cars used for emergency response), vehicles used by the armed forces on official duty, and some historic vehicles registered with the Historic Vehicle Scheme. Exemptions must be registered separately and require proof of status.
Motorcycles and mopeds pay a reduced rate compared to cars. Buses and coaches have their own rate structure. If you operate a fleet or use the crossing for business, you may be able to set up a commercial account with additional features like bulk payment options and detailed reporting.
Common Mistakes and How to Avoid Them
The most common mistake is crossing without realizing payment is required and then not paying within the ten-day window. Many drivers assume they can pay at a booth or that the crossing is free. Reading the signs before you enter the crossing zone and knowing the payment important date prevents this.
Another mistake is providing an incorrect or outdated email address when registering. If your email is wrong, you will not receive payment reminders or penalty notices, and you may miss the appeal important date. Keep your account details current and check your email regularly if you cross frequently.
A third mistake is confusing the Dart Charge important date with other toll systems. The Dart Charge payment window is ten days after crossing. Other UK toll systems, such as the Congestion Charge in London, have different important date. Check which system applies to your route before you travel.
Frequently Asked Questions
Can I pay cash at the Dartford Crossing?
No. The Dart Charge system is entirely electronic. There are no toll booths or cash payment options. You must pay online, through a registered account, or face a penalty notice. If you do not have internet access, you can call the Dart Charge customer service line to pay by phone using a debit or credit card.
What if I cross by mistake and do not want to pay?
You still owe the charge. The Dart Charge system does not refund or waive charges for accidental crossings. However, if you crossed in error — for example, you took a wrong turn — you can contact Dart Charge customer service to explain. They may consider a one-time refund or credit, but this is not may provide and must be requested within a reasonable time of the crossing.
Do I have to register an account if I only cross once?
No. You can pay online as a one-time user without creating an account. You have until midnight on the day of crossing or up to ten days after to pay. However, if you cross more than a few times per year, a registered account saves money because the per-crossing rate is lower.
What if I did not receive a penalty notice?
Penalty notices are sent by post to the registered keeper's address. If you moved house or the address on your vehicle registration is outdated, you may not have received it. You can check whether you have an outstanding penalty by entering your vehicle registration on the Dart Charge website. If you find an unpaid penalty, you can still pay it or appeal, though the appeal window closes 28 days after the notice was issued.
Can I dispute a penalty if I paid late?
Paying late does not prevent a penalty from being issued. The penalty is triggered by non-payment within ten days, not by how late you eventually pay. However, if you can prove you paid within the ten-day window, you can appeal the penalty. Keep your payment confirmation email as evidence.
