The Heritage Alliance, established in 2002 as Heritage Link, is the biggest alliance of heritage interests in the UK and was set up to promote the central role of the non-Government movement in the heritage sector.  The Heritage Alliance has 90 members; national and major regional organizations including The National Trust, the Council for British Archaeology, the Campaign to Protect Rural England (CPRE) and The Society for the Protection of Ancient Buildings (SPAB) as well as many smaller and more specialized heritage groups.

The Heritage Alliance aims to be an authoritative, respected and influential advocate for the non-government heritage sector; share knowledge and experience across the sector; be the catalyst for collaborative working in the sector and beyond; and connect heritage with the big issues in 21st Century society.  It provides a forum for members to formulate and promote policy on core issues, a support, and information network and participates in all the major sectoral fora.
