Hall began the 2015–16 season by playing the full 90 minutes in a 3–2 away defeat to Yeovil Town on 22 August 2015. Three days later, he came on as a 61st-minute substitute for Pelly Ruddock Mpanzu as Luton took Premier League club Stoke City to a penalty shoot-out in a League Cup second round fixture, only to lose 8–7 on penalties after the match ended 1–1 after extra-time. During a 2–1 home defeat to Plymouth Argyle on 24 October 2015, Hall received two yellow cards within a couple of minutes of each other and was subsequently sent off. However, this caused some confusion because it wasn't made clear in the aftermath of the first incident that Hall had been a shown a yellow card, thus he wasn't expecting a subsequent red card following the second incident. This led to an apology from the Football Association after Luton sought clarification from both them and the referee which determined that the referee did not make it clear who received the yellow card in the first incident, but Hall would still be suspended for the next fixture against Dagenham & Redbridge. Hall's next appearance was during a 4–3 home defeat to Northampton Town, coming on as an 88th-minute substitute for Sean Long, a result which led to the sacking of manager John Still. He featured twice under caretaker manager Andy Awford, in a 0–0 draw with Portsmouth on 28 December 2015, followed by a 2–0 away defeat to Bristol Rovers five days later. Hall also featured in the first match under new Luton manager Nathan Jones, a 0–0 draw with Cambridge United two weeks later, but went off with a foot injury after 65 minutes and was replaced by Paddy McCourt. He returned to the matchday squad for a home fixture against Hartlepool United on 20 February 2016, coming on as a 72nd-minute substitute for Alex Lawless during a 2–1 win. However, a succession of injuries ruled him out for the rest of the season, after which Luton announced he would be released upon the expiry of his contract, a decision manager Nathan Jones described as 'logical' as a result of missing a significant amount of training and a lack of game time.
