NABMA was instrumental in reforming the APPMG (The All-Party Parliamentary Markets Group) in 2021 .

The APPMG is a cross party group within Westminster working with the national organisations supporting, promoting and delivering markets and market trading in the UK.

The lead organisations are NABMA (the National Association of British Market Authorities) and NMTF (the National Market Traders Federation). Its aims are the promotion and support for markets and market trading in the UK with connectivity to government in terms of the role and influence of markets in retail, tourism, employment, hospitality and leisure sectors. Also providing a conduit for discussions about market strategy and operational issues between the market industry and government.
