The Welsh County Councils first formed CLAW in 1962, in response to government encouragement to develop educational building systems and create bulk purchase arrangements for quality components.

In 1979 the Welsh district authorities were invited to join CLAW, allowing the purchase benefits to be extended to other facilities such as housing.

In the mid 80’s CLAW recognised the need to expand beyond the purchasing role to share technical information, experience and expertise as a means of increasing efficiencies and good practice. A number of technical working groups were created to consider a variety of issues

Since the 1996 reorganisation of local government in Wales CLAW has developed an important role as the leading Welsh local government forum for developing and sharing best practice in the management of property assets in the public sector. All local authorities in Wales are members of CLAW which has close links with the Wales Assembly Government and the Wales Audit Office.
