The Association of United Kingdom Oil Independents (AUKOI) is a Membership organisation that represents generally the interest of its Members. Its Members are all companies involved with the wholesale sales, distribution and retailing of petrol, diesel and other petroleum products in the UK, other than the oil majors/refiners. The Members of AUKOI are variously involved with retail supply, as both independent retailers and supermarkets and represent at least 20 % of the petrol/diesel retail market in the UK.

AUKOI represents its Members in such matters as co-ordinating views on proposed legislation and associated regulations that affect its Members directly or indirectly. It provides assistance and insight into Governments proposals and those of the European Union and is itself a member company of UPEI - the Union of European Petroleum Independents. It is consulted by various Government Departments and contributes its Members' appropriate views with regard to new legislation and regulations.

AUKOI Members recognise that to prosper requires the efficient provision of goods and services to its customers.
