List of trade unions in the United Kingdom

This is a list of trade unions in the United Kingdom formed under UK labour law. The criteria for being an independent trade union, free from employer influence and domination, are set out in Section 5 of the Trade Union and Labour Relations (Consolidation) Act 1992. The body which oversees unions, and awards a certificate of independence for the purpose of collective bargaining is the Trades Union Certification Officer. For the context and history see Trade unions in the United Kingdom.

Union confederations

• Trades Union Congress (TUC)
• Scottish Trades Union Congress (STUC)
• General Federation of Trade Unions (GFTU)

Notes

1. Both the TUC and STUC require unions to be independent to be affiliated.
2. Though listed as a trade union on the COs register, the TUC is actually a confederation with each member listed being a separate affiliated union.
3. It is possible that WISA was founded prior to 2004. Please amend if an official founding date can be found.
