WHSSC (hosted by Cwm Taf Morgannwg University Health Board) was established in 2010 by the seven Local Health Boards in Wales to ensure that the population of Wales has fair and equitable access to the full range of specialised services.

WHSSC are responsible for the joint planning of Specialised and Tertiary Services on behalf of Local Health Boards in Wales.

In establishing WHSSC to work on their behalf, the seven Local Health Boards (LHBs) recognised that the most efficient and effective way of planning these services was to work together to reduce duplication and ensure consistency.
