Millions of London commuters may have been overcharged for their journeys after a technical fault hit Transport for London's contactless payment system, TfL has confirmed.
The transport authority has launched an investigation into the 'glitch' affecting bank card and mobile payment transactions across the Tube, buses, trams, DLR, London Overground, Elizabeth line, and National Rail services in the capital.
TfL acknowledged passengers have been charged more than the expected fare for their journeys, though the exact scale and nature of the technical fault remains under investigation. The organisation is working to identify the root cause and implement a fix.
A TfL spokesperson said customers who believe they have been incorrectly charged should check their journey history via the TfL website or app. Those who identify an overcharge can contact TfL's customer service team directly to request a refund.
"We are aware of the issue and are committed to ensuring all passengers are charged correctly for their travel," the spokesperson added.
The fault affects a system used by millions of commuters daily across London's transport network. For passengers already facing rising living costs, unexpected overcharges create both financial inconvenience and the administrative burden of claiming refunds.
The incident highlights the critical importance of reliable fare collection systems for maintaining public trust in London's transport network, which remains essential for the city's economic recovery and daily operations.
