In his second season at Yeovil Town, Gillett switched shirt from 23 to 18. Gillett continued rehabilitating from his injury throughout the year and wasn't until in mid-December when he was one step closer from full recovery and made his first appearance of the season, appearing as an un-used substitute bench in the FA Replay against Carlisle United. Gillett then made his first appearance of the season on 30 January 2016, where he came on as a substitute for Liam Walsh in the 82nd minutes, in a 3–2 win over Wimbledon. Gillett went on to make six appearance for the club.
