On 4 July 2023, Jameson signed for Hartlepool United on a season-long loan.[9] Having started the season as the second choice goalkeeper behind Joel Dixon, he made his Hartlepool debut in a 2–1 home win against Wealdstone in early September.[10][11] After losing his spot as number one the following month, he regained the starting position in March amidst a change of management.[11] He made 21 appearances for Hartlepool United in total.[1] At the end of the 2023–24 season, he was released by Harrogate.[12]
In July 2024, Jameson returned to former club Darlington, where he was reunited with his former York manager Steve Watson, who said: "In my opinion, Pete is the best keeper at this level. When he was with me at York, he saved us numerous points, and since then, he has gained more experience in the Football League and the National League and got even better."[13]
