I forgot to pay the Dart Charge, what happens now?
If you use the M25 Dartford Crossing and don’t pay the charge by midnight the day after you cross, you’ll be liable for a £70 Penalty Charge Notice (PCN). This will be sent to the address your vehicle is registered to.
Once you receive the PCN, head to the gov.uk website  where you will be required to enter the Penalty Charge Notice number and your vehicle registration number. You will then be asked to pay the PCN. We advise you to pay the Dart Charge penalty within 14 days to reduce the cost of the fine to £35.
