The company is challenging Transport For London's decision to revoke its operating license.
An Uber spokesperson today said: "While we have today filed our appeal so that Londoners can continue using our app, we hope to continue having constructive discussions with Transport for London. As our new CEO has said, we are determined to make things right."
Since arriving in London, Uber has become a popular service for clubbers in the city. When TFL announced its decision last month, it said Uber was "not fit and proper to hold a private hire operator licence," adding that the private-hire company's "approach and conduct demonstrate a lack of corporate responsibility in relation to a number of issues which have potential public safety and security implications."
