贝里•范皮尔

Van Peer won two events on the PDC Development Tour in Coventry in April 2015. He went on to finish third in the 2015 Development Tour Order of Merit and was subsequently awarded a two-year PDC Pro Tour card for 2016 and 2017.

Van Peer qualified for the UK Open and Players Championship Finals in 2016, losing in the second round of each event. He also reached the final of the 19th Development Tour tournament of the year and was defeated 4−3 by Mike de Decker. Van Peer qualified for the final of the PDC World Youth Championship. He played Corey Cadby in the final in Minehead, England in November, but lost 6−2.

Whilst playing at the 2017 Grand Slam of Darts, Van Peer suffered a severe case of dartitis during his match with two time World Champion Gary Anderson. Former player and now Sky Sports pundit Wayne Mardle has talked about his struggles with dartitis and has thrown his support behind the young tyro, even touting him as a future champion despite his struggles with the condition. Despite his visible struggles on stage, Van Peer defeated both Simon Whitlock and Cameron Menzies in the group stage, before losing out to Mensur Suljović in the second round.

Van Peer enjoyed somewhat of a comeback year during 2023, claiming four challenge tour titles to earn a spot at both the 2023 Grand Slam of Darts and the 2024 PDC World Darts Championship. At the latter of the two, he defeated both Luke Woodhouse and Josh Rock to reach the third round on debut, where he was defeated by Damon Heta.
