The current health boards were created on 1 October 2009 following a reorganisation of NHS Wales that saw the abolition of the 22 local health boards (LHBs) and seven NHS trusts that had existed since 2003. Since the reorganisation health boards have been responsible for delivering all NHS services, replacing the two-tiered trust and LHB system. In April 2019 responsibility for health services in Bridgend County Borough was transferred from the former Abertawe Bro Morgannwg University Health Board to the former Cwm Taf University Health Board, leading to changes in names and boundaries for both health boards.
