A London resident faced escalating penalty charges after mistakenly paying for the wrong tunnel crossing in preparation for a trip to northern France. Jonathan, a pensioner living in the capital, intended to pay the charge associated with the Blackwall Tunnel, which Transport for London (TfL) began charging for in April 2025. Instead, he inadvertently paid the toll for the Dartford Crossing, a distinct facility managed by National Highways located approximately 16 miles away from the Blackwall Tunnel.
Jonathan had planned to travel by car and ferry to Le Touquet, France, at the end of July, and sought to settle toll payments for two tunnel crossings in advance. He searched for the "Dartford Tunnel" rather than the "Blackwall Tunnel" and paid for the Dartford crossings accordingly. Shortly after his journey, he received a £90 penalty charge notice from TfL explaining nonpayment for the Blackwall Tunnel. Despite promptly appealing the penalty and then a second notice, Jonathan received no timely confirmation and was subsequently notified by phone that his appeals were unsuccessful.
The penalty charges continued to increase, doubling from £90 to £180, with the risk of rising to £270 after 28 days of nonpayment. Jonathan expressed concern that the charges would continue to mount despite his clear intent to pay, albeit for the incorrect tunnel. As a pensioner, the accumulation of fines posed a significant financial burden.
Following intervention by a third party, TfL reviewed the case and ultimately waived the penalty charges, accepting payment of the original toll amount Jonathan should have paid for the Blackwall Tunnel. In a statement, TfL acknowledged the error and expressed regret for the distress caused. The agency explained it had exercised discretion to cancel the fines, recognizing Jonathan’s genuine mistake and prior payment for the Dartford Crossing.
TfL charges £4 per Blackwall Tunnel crossing during peak times, with a planned increase to £4.20 effective September 21. Payments must be made by midnight on the third day after travel, or a penalty notice is issued, which is reduced if paid promptly but escalates over time. The Blackwall Tunnel toll is overseen by TfL, whereas the Dartford Crossing is administered separately by National Highways, which may have complicated the appeals process in Jonathan’s case.
TfL advised that appeals against penalty charges can be protracted but noted that reasonable grounds—such as unauthorized vehicle use or not being the registered keeper—can result in fines being overturned. Following a rejected appeal, motorists receive a formal notice with the option to escalate the case to the Road User Charging Adjudicator, an independent tribunal handling disputes related to London’s congestion charge, emission zones, and toll crossings such as the Blackwall and Silvertown tunnels. Importantly, the penalty accrual pauses during the appeal process.
The episode underscores the potential confusion caused by managing similar but separately administered toll crossings and highlights the importance of carefully verifying payment details, particularly as road user charging expands across London.
