As part of a deal with AEG Global Partnerships, there are ticket giveaways for Deliveroo customers, a giant slot machine in the form of a takeaway box which offers prizes and a dining area for customers in the Barclaycard VIP Summer Garden.
The event which kicked off last week and runs until 10 July, features headline performances from Take That, Massive Attack, Florence and the Machine and Stevie Wonder.
The brand is also operating an exclusive backstage space for artists and performers, allowing them to order their favourite foods from a range of top London restaurants.
Dan Warne, managing director, UK & IE at Deliveroo, said: "Our customers are just as passionate about great music as they are about quality of food. The opportunity to partner with Barclaycard British Summer Time was music to our ears."
Nathan Kosky, VP of AEG global partnerships, said: "Deliveroo is an innovative and growing brand offering the best experience to their customers. They’re a perfect fit for one of the best festivals in the UK this year. We know fans at British Summer Time will love what Deliveroo can add to their experience."
