What Is the Dartford Crossing and Why Does It Matter?
The Dartford Crossing—which includes the Queen Elizabeth II Bridge and twin tunnels under the River Thames—is one of the busiest road crossings in the UK. It connects Kent and Essex and forms part of the M25 orbital motorway, making it a vital link for commuters, hauliers, and holidaymakers alike.
To reduce congestion, the toll booths were removed in 2014, and a cashless payment system called Dart Charge was introduced. Motorists must now pay online or via a Dart Charge account.
Failure to pay the correct fee on time results in an automatic Penalty Charge Notice (PCN).
What’s Changed in 2025 – Why Drivers Are Getting Caught Out
In 2023, National Highways transitioned Dart Charge to a new service provider. As part of this shift, all existing Dart Charge account holders were required to revalidate their payment card information.
Unfortunately, only around 770,000 of 1.7 million users completed this step. That left nearly 1 million drivers at risk, many of whom were unaware their cards had expired or were no longer linked to their accounts.
Compounding the issue, some drivers have experienced:
- Account suspensions without notification
- Unrecognized number plates due to plate changes or registration errors
- Missed notifications due to outdated email or address details
As a result, a wave of £70 fines has hit drivers unaware they were no longer in compliance. Read more about the 2023 transition in this BBC report.
