What Dart Charge is and who has to pay it

Dart Charge is a toll system for the Dartford Crossing, a bridge and tunnel that carries traffic across the River Thames between Essex and Kent in southeast England. If you drive through the crossing, you must pay a charge — there is no cash payment option at the barrier. The charge applies to most vehicles, including cars, vans, motorcycles, and larger vehicles, though the amount varies by vehicle type.

The crossing is operated by a private company under a concession agreement, and the toll revenue goes toward maintaining and operating the bridge and tunnel. The charge is not optional: if you cross without paying, you will receive a Penalty Charge Notice (PCN) in the post, which carries a fine that starts at £70 and increases if you do not pay within a set timeframe.

The crossing handles roughly 160,000 vehicles per day, so it is one of the busiest toll points in the UK. Most drivers now pay using the Dart Charge system rather than stopping at a booth, which has made the crossing faster but requires you to understand how payment works and what happens if you miss a important date.

How to pay Dart Charge before the important date

Payment must be made by midnight on the day after you cross. This means if you drive through on a Monday, you have until midnight on Tuesday to pay. The official Dart Charge website (dartcharge.com) is the main payment route: you enter your vehicle registration number, the date you crossed, and your payment details. Payment takes a few minutes and is processed when ready.

You can also pay by phone on 0300 111 0011 (available 24 hours, seven days a week). If you cross the Dartford Crossing regularly — for work, commuting, or frequent travel — you can set up a Dart Charge account with automatic payments. This removes the need to remember the important date each time and can save you money: account holders pay a discounted rate compared to one-off payments.

Some payment methods may incur a small processing fee, so check the website for current charges. If you are unsure whether you have already paid, you can check your payment history on the Dart Charge website by entering your registration number.

Charges by vehicle type and account discounts

The toll amount depends on what you are driving. Cars are charged the standard rate, which varies but is typically in the region of £2.50 for a one-off payment. Motorcycles pay a lower rate, while vans, minibuses, and HGVs pay progressively higher amounts. Buses and coaches have their own rate structure.

If you set up a Dart Charge account and use it regularly, you pay a discounted rate per crossing. The more you cross, the greater the saving compared to paying one-off charges. For example, a regular commuter who crosses five days a week will save considerably over the course of a year by using an account rather than paying individually each time.

The exact charges change periodically and are set by the operator. Always check the Dart Charge website for the current rates before you travel, as prices may have been updated since your last crossing.

What happens if you do not pay on time

If you do not pay by midnight the day after crossing, you will receive a Penalty Charge Notice (PCN) in the post within two to three weeks. The PCN will be addressed to the registered keeper of the vehicle — the person whose name appears on the vehicle registration document (V5C).

The initial penalty is £70 if you pay within 28 days of the PCN being issued. If you do not pay within 28 days, the fine increases to £105. If you ignore the notice entirely, the matter may be escalated to a debt collection agency or court proceedings, which will add further costs and legal complications.

You can appeal a PCN if you believe it was issued in error — for example, if you have proof that you already paid, or if there was a genuine fault with the payment system. Appeals must be submitted in writing within 28 days of the PCN date. The Dart Charge website provides guidance on how to submit an appeal and what evidence to include.

Discounts and exemptions for residents and disabled drivers

Residents of certain postcodes in Essex and Kent near the crossing are may have access to to a 50% discount on Dart Charge tolls. To receive this discount, you must register separately with Dart Charge and provide proof of residence, such as a council tax bill or utility bill. The discount applies automatically once your account is set up, and you will pay the reduced rate on every crossing.

Some disabled drivers may also be may have access to to a discount or exemption. The rules vary depending on the type of disability and the vehicle used. You will need to provide evidence of your disabled status — typically a Blue Badge or a letter from a healthcare professional — when you register. Contact Dart Charge directly to discuss your circumstances and find out whether you may have access to.

These discounts and exemptions are not automatic: you must register to receive them. If you think you are may have access to to a discount, visit the Dart Charge website or call 0300 111 0011 to start the registration process.

What to do if you receive a Penalty Charge Notice

Open the PCN as soon as it arrives and check the details carefully. The notice will show the date you crossed, your vehicle registration, and the amount you owe. If all the details are correct and you straightforward forgot to pay, you can settle the fine when ready by paying the amount shown (£70 if within 28 days, £105 after 28 days).

You can pay the PCN online through the Dart Charge website, by phone, or by post using the payment slip included in the notice. Keep proof of payment — a receipt or confirmation email — in case there are any disputes later.

If you believe the PCN was issued in error, or if you have a legitimate reason why you could not pay (such as a serious illness or a genuine system fault), you can submit a formal appeal. Write to the address shown on the PCN and include your evidence. Appeals must be received within 28 days of the PCN date. If your appeal is rejected, you will be told how to proceed and what your next options are.

Planning ahead: tips for avoiding missed payments

The simplest way to avoid a fine is to set up a Dart Charge account if you cross regularly. Automatic payments mean you never have to remember a important date, and you benefit from the discounted rate. Even if you only cross a few times a year, an account removes the stress of remembering to pay within 24 hours.

If you do not have an account and you cross occasionally, pay as soon as you reach your destination or within a few hours. Do not wait until the evening of the next day, as technical issues or delays in processing could push you past the midnight important date. Keep a note of the date you crossed so you can check your payment history later if needed.

If you are hiring a vehicle or borrowing someone else's car to cross the Dartford Crossing, check with the owner or hire company about who is responsible for paying the toll. Some hire companies charge the toll to your credit card automatically; others expect you to pay and claim it back. Clarify this before you travel to avoid confusion.
