Deighton High School closed on 31 August 1992, and most students and some staff were relocated to Fartown High School. The centre was refurbished as a sports/music venue, and utilised by the Local Authority, Kirklees Council, for staff training. Next door to the centre, the Deighton Sports Arena was developed which houses a gym, squash court and basketball court and is a venue for dancehall music. In March 2016 the Deighton Centre was demolished.
