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 the Trade Union and Labour Relations (Consolidation) Act 1992 section 5. 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.
