Dartford Crossing Fines: How Much, How to Appeal, and How to Avoid Them
Millions of drivers have been fined for not paying the Dartford Crossing charge since the barrier-free system launched in 2014. A single missed payment of £3.50 can escalate to over £157 if left unchecked. This guide explains exactly how the fine system works, how much you will pay at each stage, how to appeal if you have grounds, and — most importantly — how to make sure you never get fined in the first place. Last verified April 2026.
Fine Escalation Timeline
The Dart Charge penalty system follows a clear escalation path. At every stage, the amount owed increases. Understanding this timeline is critical because acting early can save you hundreds of pounds. The difference between paying within 14 days and ignoring the PCN entirely could be the difference between £35 and £250+.

First-Time Grace Period — Most Competitors Miss This
If this is your first-ever Penalty Charge Notice from Dart Charge, you may be able to cancel the penalty entirely. Many first-time offenders report that they were offered the option to pay just the original crossing charge (£3.50 for a car) within 14 days of receiving the PCN, with the £70 penalty being waived completely.
This first-time grace period is not officially guaranteed, and Dart Charge has discretion over whether to offer it. However, it is widely reported across motoring forums and consumer advice sites. If you receive a PCN and it is your first offence, look carefully at the letter — it may contain instructions for paying the original charge instead of the penalty amount.
Important: This grace period only applies to your very first PCN. Any subsequent Penalty Charge Notices will incur the standard £70 fine (or £35 if paid within 14 days). This is another reason why setting up a pre-pay account is the smartest long-term approach — it eliminates the risk of future penalties entirely.

How to Appeal a Dart Charge Fine
If you believe your PCN was issued incorrectly, you have the right to make a formal representation (appeal) within 28 days of receiving it. The appeal process is free and can be done online or by post. Dart Charge must respond to your representation within 56 days. If they reject your appeal, you can escalate to the independent Traffic Penalty Tribunal for a final, binding decision.
Appeal Online
Submit your representation at dartcharge.service.gov.uk. You will need your PCN number and vehicle registration. Upload any supporting evidence (receipts, photos, documents).
Appeal by Post
Write to: Dart Charge, PO Box 842, Leeds, LS1 9QF. Include your PCN number, vehicle registration, and a clear explanation of why you are appealing. Enclose copies (not originals) of supporting evidence.
Valid Grounds for Appeal
Your appeal must be based on one of the following recognised grounds. Simply saying you forgot to pay or did not know about the charge is unfortunately not a valid reason for appeal — the signage requirement for barrier-free charging has been upheld in multiple tribunal decisions.
Already paid
You made the payment on time but it was not recorded correctly. Keep your receipt or bank statement as evidence.
Number plate misread
The ANPR camera misread your registration. Provide a photo of your number plate and evidence you were not at the crossing.
Not the driver
Someone else was driving your vehicle. You must name the actual driver and provide their details.
Disabled Taxation Class
Your vehicle is in the Disabled Taxation Class but was not registered with Dart Charge. Register it now and provide proof of your tax-exempt status.
Vehicle was stolen
Your vehicle was stolen at the time of the crossing. Provide the police crime reference number.
Directed by emergency services
You were directed through the crossing by police or other emergency services and had no choice about the route.
Signage unclear or missing
The signage indicating the need to pay was obscured, missing, or unclear at the time of your crossing.
Traffic Penalty Tribunal (Second Appeal)
If Dart Charge rejects your formal representation, you have 28 days to escalate your case to the Traffic Penalty Tribunal (TPT). The TPT is an independent body that reviews road user charging penalties across England and Wales. Their decision is final and binding on both you and the charging authority.
TPT hearings are typically conducted by phone or in writing — you do not usually need to attend in person. The tribunal adjudicator will review all the evidence from both sides and make a decision. If the adjudicator rules in your favour, the PCN is cancelled and you owe nothing. If they rule against you, you must pay the outstanding amount within 28 days.
You can submit your TPT appeal online at trafficpenaltytribunal.gov.uk. The process is free and straightforward. Include all the evidence you submitted to Dart Charge plus any additional information that supports your case. Adjudicators are experienced and will consider reasonable arguments — the key is to present your case clearly and concisely with supporting evidence.
What If You Have Multiple PCNs?
Each crossing that was not paid for generates a separate PCN. If you crossed five times without paying, you will receive five separate PCNs, each for £70 (or £35 if paid within 14 days). This can quickly add up to several hundred pounds. It is not uncommon for regular commuters who assumed payment was automatic (from the old barrier system) to receive multiple PCNs in a short period.
If you have received multiple PCNs, the best approach is to pay them all within the 14-day reduced-rate window (£35 each) to minimise your total liability. If this is your first set of offences, contact Dart Charge on 0300 300 0120 and explain the situation — they may offer the first-time grace period on the first PCN, even if subsequent ones must be paid in full.
Going forward, set up a pre-pay account immediately to ensure this never happens again. The few minutes it takes to register could save you hundreds of pounds in future penalties.
How to Avoid Dartford Crossing Fines
Prevention is always better than cure. Here are the most effective ways to ensure you never receive a Dart Charge Penalty Charge Notice.
Set up a pre-pay account
The single best step you can take. Auto-deduction means you never need to remember to pay, and you save 20% per crossing. Set up now.
Download the Caura app
If you prefer not to use a pre-pay account, the Caura app lets you pay in two taps. No extra fees. Keep it on your home screen as a reminder.
Set a phone alarm
After crossing, set an alarm for the same evening with "Pay Dart Charge" as the label. Simple but effective for one-off crossings.
Cross between 10pm and 6am
Crossings during the free period generate no charge, so there is nothing to forget. See charge times for details.
