When your card clashes London, a payment error that happens when your Oyster or contactless card is charged twice for the same journey or fails to register properly. Also known as Oyster card overcharge, it’s one of the most common frustrations for anyone who uses London’s public transport regularly. You tap in, you tap out, but your bank statement shows two charges for one trip. Or worse—you get charged for a journey you didn’t even take. It’s not just annoying; it’s money leaking out of your pocket.
This isn’t rare. Thousands of people face this every month. The system isn’t broken—it’s just messy. TfL refund, the official process to recover money lost due to overcharges or missed taps on London’s transport network exists for a reason. You don’t need to accept it. You don’t need to call customer service for hours. You just need to know where to go and what to click. The same goes for London transport refund, a broader term covering all types of overpayments on the Tube, DLR, Overground, and even some buses. It’s not magic. It’s a form. And it works.
Most people don’t realize their card clash isn’t their fault. Maybe you tapped on a busy platform and the reader missed it. Maybe you switched lines and your card got confused. Maybe you used a different card on the same journey and the system thought you were two people. It happens. But you’re still the one who gets charged. That’s why knowing how to fix it matters. You can get your money back in days, not weeks, if you act right. And it’s free—no hidden fees, no third-party scams.

Guides that explain why your contactless card got double-billed on the DLR. Tips on how to spot a failed tap before it hits your bank.

It’s what works when the Tube system glitches—and it happens more often than you think.
