Founded in 1971, and funded entirely by member subscriptions, the Flag Institute documents, celebrates and promotes flags in all their variety, sharing knowledge, opinion and ideas – in person, in print and online.

In the absence of a UK Flag Act, the Flag Institute acts as the de facto authority on flags flown in the UK and the Crown Dependencies and Overseas Territories. It provides expert advice to national and local government, diplomatic services, military units and more; encourages local communities to create and adopt their own flag through open competition and democratic vote; and maintains the free UK Flag Registry as the formal record of current designs.

Welcoming members from all six continents, the Flag Institute is also proudly international in scope and outlook. It is a full member of the International Federation of Vexillological Associations (FIAV) – a worldwide network of c.50 flag organisations. It is also a three-time host of the biennial International Congress of Vexillology (ICV) – most recently in London in 2017.

The Flag Institute Flag

Designed by Graham Bartram, Chief Vexillologist, and Philip Tibbetts, Communities Vexillologist, the flag of the Flag Institute depicts a stylised representation of a quarter of the Union Flag, creating a dynamic emblem representing vexillology moving forward.
