Ben, from Exeter, became Exeter City's youngest first-team player in 2019 and joined Aston Villa the following year.

 Ben started in City’s academy as an under-11 and played for England at under-15 and under-16 level whilst registered with the club. He was reported as training with Liverpool in the summer before his final year at school with later talk of interest from Chelsea.

Following in Ethan Ampadu’s footsteps, and breaking Ethan’s record as City’s youngest-ever player, Ben played - before starting year 11 - against Coventry City in the League Cup on 13 August 2019. He was aged 15 years 7 months, 1 day. Ben later made three substitute appearances in the Football League Trophy before making his league debut, as a substitute, against Cambridge United on 11 January 2020.

Ben moved to Aston Villa for an undisclosed fee in August 2020. Julian Tagg, club president and director of football and external affairs, announced that: 

“Whilst the fee is undisclosed, when a possible arbitration fee is considered we are pleased with the valuation. Aston Villa have been very professional and fair in their dealings with Exeter City and we as a club would like to acknowledge that.” 

During 2020/21 Ben appeared for Aston Villa under-21s in the EFL Trophy and played in the team that won the FA Youth Cup scoring in the final against Liverpool on 24 May 2021. He made his first-team debut for a young Villa side against Liverpool in the FA Cup on 8 January 2021 before signing his first professional contract a few days later. 

In 2021/22 Ben appeared in the EFL Trophy again, was an unused substitute for a number of Premier League games and signed a new contract in January 2022. 

In August 2002 Ben signed for Kilmarnock on a season-long loan. He made a promising start at Rugby Park but, after playing against Celtic in the Scottish League Cup semi-final at Hampden Park on 14 January 2023, Ben suffered an injury which kept him out for the rest of the season. Returning to Villa he appeared twice for the under-21s in the EFL Trophy during the autumn of 2023 before joining Blackburn Rovers on loan in January 2024.
