The key legislation covering equal pay from 1 October 2010 onwards is the Equality Act 2010 which represents the most significant overhaul of the legislation since the Equal Pay Act 1970.

Previously the key legislation covering equal pay was the Equal Pay Act 1970.
The principle of equal pay for equal work originates with European legislation and can be found within Article 141 (formerly 119) of the Treaty of Rome which provides that men and women should receive equal pay for equal work. Great Britain courts and tribunals must therefore interpret the Equality Act 2010 and other legislation in a way that is consistent with Article 141 and European Union (EU) legislation such as Directive 2006/54/EC on the implementation of the principle of equal opportunities and equal treatment of men and women in matters of employment and occupation.
UK and EU equal pay legislation has historically been very complex and the Equality Act 2010 has not simplified equal pay issues to any significant extent.
The Equality and Human Rights Commission (EHRC) has published a comprehensive Code of practice on equal pay. The Code applies to England, Scotland and Wales and was published on 6 April 2011, together with another code on employment generally.
The Code must be taken into account where relevant in proceedings, and:
- provides detailed explanations of the equal pay provisions in the Equality Act 2010,
- applies the legal concepts to everyday situations,
- does not impose legal obligations or give an authoritative statement of the law, but
- can be used in evidence in equal pay claims.
In addition to the Code the EHRC website also produces less formal information on equal pay.
