A group of British start-up companies are trying to disrupt the food takeaway business, by making it easier for restaurants to deliver, that wouldn’t normally consider it.

The largest of these is Deliveroo, now operating in major cities including London, Brighton, Nottingham and Edinburgh. It uses mobile internet technology to connect drivers and restaurants, and an army of electric bikes.

To find out how it works, the BBC’s Dougal Shaw followed Deliveroo rider Rafal around for the lunchtime rush in Islington, London.

He also spoke to the company’s co-founder, Will Shu, at one of the restaurants he has signed up, Dishoom in King’s Cross, London.

Rivals in this growth are include Dinein and Meals.
