Forgot to Pay the Dartford Crossing? What Happens Next

Do not panic. You have until midnight the next day. After that, here is what to expect and how to deal with it.

The Timeline

You crossed the Dartford Crossing

Cameras read your number plate. The clock starts.

By midnight the next day: Pay normally

Pay online at gov.uk/dart-charge, by phone (0300 300 0120), or at Payzone. Cost: £2.50 (car) or £2.00 (pre-pay). No penalty.

Missed the deadline: Penalty Charge Notice (PCN)

You will receive a PCN in the post within 28 days. The charge is £70. Pay within 14 days and it is reduced to £35.

Ignore the PCN: Charge increases

After 28 days without payment or appeal, the charge rises to £105. A Charge Certificate is issued. If still unpaid, it goes to a county court and becomes £157.50 plus court costs.

Fine Escalation

StageAmountDeadline
Normal payment£2.50By midnight next day
PCN (early payment)£35Within 14 days of PCN
PCN (full amount)£70Within 28 days of PCN
Charge Certificate£105After 28 days
County Court£157.50+Plus court costs

How to Pay Late (But Before the PCN)

If you are past midnight but have not received a PCN yet, pay anyway. Sometimes the system accepts late payments within 2-3 days. It is worth trying:

  • Online: gov.uk/dart-charge - enter your registration and pay
  • Phone: 0300 300 0120 (available 24/7)
  • Payzone: Any Payzone outlet with your registration number

How to Appeal a PCN

You can appeal within 28 days of receiving the PCN. Common successful grounds:

  • • You paid but the payment was not recorded (keep your receipt/confirmation)
  • • Your number plate was misread by the camera
  • • You were not the driver (you must name the actual driver)
  • • You have a Blue Badge exemption and it was not registered
  • • The vehicle was stolen at the time of crossing
  • • The signage was unclear or you were directed onto the crossing by emergency services

Appeal online at dartcharge.service.gov.uk or by post to Dart Charge, PO Box 842, Leeds LS1 9QF.

How to Avoid This in Future

  • Set up a pre-pay account: £2.00 per crossing (saves £0.50 each time) and auto-deducts so you never forget
  • Pay before you cross: You can pay up to 24 hours in advance
  • Set a phone reminder: If you cross, set an alarm for that evening to pay
  • Use the Dart Charge app: Get notifications and pay instantly

Key point: A £2.50 crossing costs £35 if you pay the PCN within 14 days, or £157.50+ if it reaches county court. Set up a pre-pay account and never think about it again.
