The six-part series, coming to TV in 2024, follows five talented under-privileged black students from inner-city London as they gain scholarships at St Gilbert's, an elite boarding school.
This selection of new pictures gives viewers their first glimpse of the cast including Josh Tedeku as Jaheim, Jodie Campbell as Leah, Myles Kamwendo as Omar alongside Sekou Diaby as Toby and Aruna Jalloh as Femi - both making their screen debuts.
Daniel Lawrence Taylor will also appear on screen playing Gus, a mentor figure to St Gilbert's five newest students.
The BBC and production company Studio Lambert explain: "Boarders is a high energy, coming of age comedy drama. Following a problematic viral video involving a student, our leads are offered sixth form scholarships to St Gilbert's, in an attempt to rehabilitate the image of one of the country's oldest and most prestigious schools.
"They soon find themselves in a world they can only describe as something out of Harry Potter, surrounded by lush playing fields, cloistered grandeur and complex social rules which they must decipher quickly in order to survive. They will go on a journey as they learn about themselves, their identity and what it's like to live alongside the one percent - which they discover is nothing like life as they knew it."
