Uber has been told that it will no longer be able to operate in London, with its current licence due to expire on September 30.

Transport for London (TFL) revoked its rights on the road with the conclusion that it is not a fit and proper company to hold a private hire operator license. Mayor of London Sadiq Khan has backed the decision, saying that “providing an innovative service must not be at the expense of customer safety and security”.

Unsurprisingly the US-based company has hit back, saying the decision would "show the world that, far from being open, London is closed to innovative companies".

Uber has 21 days to appeal the decision, and can operate during the appeal process. So while the company may be around for some time yet, we’ve rounded up some taxi apps that could fill the Uber-shaped void in the market.

Gett

Rather like Uber lets you order a taxi, Gett matches London's black cab drivers with their fares, and the company says that nearly half of all black cabs use the system. Rather than using the traditional metered fare, there’s the option to have a fixed fare, which Gett says can cut prices by 30%.

The on-demand taxi app has made significant advances into the cab sector over recent years, with Gett’s revenues growing by 300% in 2015.

Mytaxi

In late 2016, companies Hailo and mytaxi merged to create Europe’s largest taxi app, Mytaxi. With 10 million downloads in more than 50 cities across the continent, Mytaxi provides an easy alternative to Uber with pre-booking, cash-free, journey-sharing and multi-seater options.

It also has guaranteed fixed fares for trips to London airports.

Addison Lee

The biggest minicab company in the UK is a more flashy alternative if Uber does have to quit the capital. With fixed pricing and 4,800 cars in central London, the app works in a similar way to Uber.

However, Addison Lee does also boast London’s largest executive fleet of Mercedes cars, when not just any car will do.
