As a youth, Splatt came up through the youth system of Dulwich Hamlet.[1] From there, he joined the academy of Derby County on a two-year scholarship deal in 2018. The following year, he made his senior debut on loans at Mickleover and Carshalton Athletic.[2][3][4] In February 2020, Splatt went on a trial with EFL Championship club Barnsley which included a training match appearance against Sheffield Wednesday. He was then loaned from Derby County to the Barnsley's under-23 team.[5][6] He was not offered a new contract when his deal with Derby County expired in summer 2020.[7][8]
Following his departure from Derby County, Splatt signed for National League South club Tonbridge Angels in September 2020.[9] After making over a dozen appearances for the Angels, the player joined Whitehawk in June 2021.[10][11] He scored nineteen goals across all competitions for Whitehawk that season and earned a return to the National League South the following year, joining Worthing.[12] He remained dual-registered with Whitehawk that season to gain more playing time after being cup-tied to the club earlier in the season.[13] The forward made his full debut with Worthing on 27 February 2022, starting in a league match against Concord Rangers.[14]
Following his departure from Worthing, Splatt had a two-month stint with Billericay Town before moving on to Leatherhead.[15][16] After signing a deal with Ramsgate in summer 2022, he departed the club without ever playing a match after he received a more lucrative offer to return to Whitehawk FC where he had success the previous season.[17][18] He made his first appearance after his return in a 2022–23 FA Trophy draw with Burgess Hill Town in October of that year.[19]
In summer 2023, Splatt departed Whitehawk for the second time, subsequently having spells with Sittingbourne and Sheppey United.[20][21] During his first season with Sheppey United, the player scored on his league home debut, an eventual 2–2 draw with Herne Bay.[22] He then returned to Sheppey United the following season after finishing his first campaign with the club in top form.[23]
