Surridge returned to the Cherries academy when he joined the under-15s and was soon offered a scholarship, scoring freely for the club's youth team, before impressing during a productive loan spell with Poole Town during their debut season in the National League South in the 2016–17 season.
On 3 August 2017, Surridge joined League Two club Yeovil Town on loan until the end of the season. Surridge made his Football League debut as a second-half substitute for Yeovil against Luton Town, on 5 August 2017. He scored his first goal for Yeovil in an EFL Trophy tie against Exeter City on 29 August 2017. Surridge finished the season with Yeovil having scored 10 goals in 53 total appearances across all competitions for the club.
On 30 July 2018, Surridge joined League Two club Oldham Athletic on a season-long loan deal. Five goals from four matches in September earned him the League Two Player of the Month award, and by 6 January, he had twelve goals from twenty appearances in all competitions. Surridge scored against Premier League opposition in the third round of the FA Cup, scoring a penalty as Oldham came from behind to beat Fulham 2–1. He was then recalled by his parent club in early January.
Surridge made his Premier League debut for the Cherries in a 5–1 loss to Arsenal on 28 February 2019, replacing Ryan Fraser on the 80-minute mark. Surridge was awarded the club award for Under-21 Player of the Year on 14 May 2019, after a fruitful loan spell at Oldham Athletic and making his Premier League debut for the club against Arsenal.
On 6 August 2019, Championship club Swansea City signed Surridge on a season-long loan deal. He scored his first Swansea goal in a 3–1 away win at Queens Park Rangers on 21 August 2019 before being recalled on 1 January 2020 by AFC Bournemouth. Surridge finished the season with Swansea having scored 7 goals in 23 total appearances across all competitions for the club.
Surridge signed a new contract with the Cherries in early January 2020, a four-and-a-half-year deal that would keep him with the club until the summer of 2024. He scored his first professional goal for the Cherries in the FA Cup fourth round, with a late goal against Arsenal in a 2–1 defeat on 27 January 2020. Surridge was thought to have scored his first Premier League goal for the club, equalising 1–1 in the penultimate game of the 2019–20 season against south coast rivals Southampton. However, it was ruled out by VAR due to teammate Callum Wilson adjudged as being in an offside position. The game finished 2–0 to Southampton. Surridge was described by Cherries coach Mark Molesley as being the perfect example to loan players at non-league clubs in how to make the grade, citing his successes in loan spells at non-league level and football league clubs like Yeovil, Oldham and Swansea as being evidence of Surridge "climbing the ladder and earning his stripes".
