What work is carried out by TfL to discourage and prevent people from selling former private hire vehicles with TfL roundels and other branding/insignia still on display?

Vehicle licensees are required to inform Transport for London (TfL) of a change of ownership and must return any licence documents to TfL if the vehicle is no longer being used as a Private Hire Vehicle or taxi.

Private hire operators are required to provide a booking confirmation to passengers before their journey starts. This must include the vehicle registration mark, the first name of the driver, the driver's private hire licence number (as shown on the ID the driver is wearing) and, where the customer is able to receive it, a photograph of the driver.  Passengers can also check whether a private hire vehicle (or driver or operator) is licensed by using TfL’s online licence checker.

TfL will investigate and take appropriate action in relation to any information received which suggests that individuals are identifying themselves as being licensed, through branding, where this is not the case.
