The London mayor’s transport authority has surprised Uber and its 40,000 drivers by refusing to renew the ride-hailing company’s operating licence. We answer your questions about the decision.

Why has Uber lost its licence in London?

Transport for London said it would not renew Uber’s licence when it expires on 30 September because it was not a “fit and proper” operator. It said the US firm’s approach and conduct demonstrated a lack of corporate responsibility with potential public safety and security implications. It flagged up concerns about Uber’s handling of reporting criminal offices and obtaining medical certificates and driver background checks. It was also concerned by Uber’s use of of Greyball, which is software that can be used to block regulators from gaining full access to its app.

Will Uber stop operating immediately?

Uber has said it will appeal against TfL’s decision. It will be able to continue operating until the legal process has been exhausted. That could take months.

Can Uber get its licence back?

Uber could win its appeal in the courts and force TfL to back down. While TfL’s decision did not suggest any measures that Uber could take in order to alter its decision, if the company loses its appeal in court it may be able to make a fresh application to TfL after making changes to the way it operates.

What are the alternatives?

Uber is not the only taxi-hailing app on the market. New entrants such as Gett, Hailo and Kabbee could benefit from the demise of Uber, while many traditional local minicab operators and the likes of Addison Lee have also developed apps and better online services which could provide an alternative for travellers and drivers alike.
