Ola said it will be “fully operational from day one” in London, where it has signed up more than 20,000 drivers since late November.

The company, which has raised about $3.5 billion to date, emphasized that its platform offers a range of security features, such as a 24/7 helpline for drivers and customers and an in-app emergency button.

Safety is a sensitive subject around the globe, especially in the U.K. capital, which might explain why it took Ola additional months to launch in the city after securing the license in July last year and entering the region in 2018.

In November, TechCrunch obtained a pitch to Ola from a PR firm that specializes in government lobbying, underscoring the kind of cautious footing and lengths that ride-hailing companies are willing to go in order to get things right. Ola denied it was working with the PR firm.

Failing to follow the safety guidelines in pursuit of aggressive expansion demonstrably cost Uber its license in London. The local regulator, TfL, stripped Uber of the license — for the second time — late last year after ruling that the American giant did not meet the “fit and proper” requirements for private hire operators.

In the ruling, TfL noted that it had found more than 14,000 trips on Uber’s platform that were taken with drivers who had faked their identity. Uber CEO Dara Khosrowshahi expressed his disappointment at TfL’s decision. “This TfL decision is just wrong. Over the last 2 years we have fundamentally changed how we operate in London,” he said at the time.

Uber’s cabs remain operational in London as the company appeals the decision. Ola says it will continue its “collaborative approach with regulators and local authorities, as well as its clear focus on safety, drawing on industry-leading and global best practices.”

Additionally, Ola says to incentivize drivers on its platform it will not charge them any commission for six weeks. The company, like Uber, roughly charges between 20% to 25% commission on the final fare paid by a passenger, for instance. (It is also offering £25 worth of ride credit to passengers who sign up in the first week after the launch.)

Simon Smith, head of Ola International, said the platform has received “overwhelming positive” reception since launching in the U.K. in 2018. The startup is operational in 28 boroughs in the U.K., including cities such as Birmingham, Coventry and Warwick, where it claims to have seen more than double-digit growth in rides in the last quarter. To date, Ola has provided more than 3 million rides with more than 11,000 drivers already operating on the platform in the U.K.

“We are working closely with drivers to build a high quality and reliable service for Londoners. Launching in London is a major milestone for us and we are keen to offer a first class experience for all our customers,” he said in a statement.

Expansion into the U.K. capital, one of the world’s most lucrative markets, is a major step for Ola, which has provided about 3 million rides in the U.K. to date with more than 11,000 driver partners. Over the years, Ola has also expanded to Australia and New Zealand. The company says it is operational in more than 250 cities.
