If a TfL (Transport for London) payment gets declined, here’s what typically happens, depending on the payment method and situation:
First Decline (at a gate/validator): - The gate won’t open or the validator will show a red light. - You’ll need to use another payment method to complete your journey immediately.
TfL will attempt to re-try the payment: - They usually make up to 3 further attempts over the following few days. - If payment is taken later, your journey will be charged normally.
If payment ultimately fails: - You’ll receive an Unpaid Fare Notice via email or post. - You must pay the outstanding amount plus a £10 administration fee. - You have 30 days to pay before further action is taken.
