The primary purpose of the Act is to codify the complicated and numerous array of Acts and Regulations, which formed the basis of anti-discrimination law in the United Kingdom. This was, primarily, the Equal Pay Act 1970, the Sex Discrimination Act 1975, the Race Relations Act 1976, the Disability Discrimination Act 1995 and three major statutory instruments protecting discrimination in employment on grounds of religion or belief, sexual orientation and age. It requires equal treatment in access to employment as well as private and public services, regardless of the protected characteristics of age, disability, gender reassignment, marriage and civil partnership, race, religion or belief, sex, and sexual orientation. In the case of gender, there are special protections for pregnant women. The Act does not guarantee transsexuals' access to gender-specific services where restrictions are "a proportionate means of achieving a legitimate aim". In the case of disability, employers and service providers are under a duty to make reasonable adjustments to their workplaces to overcome barriers experienced by disabled people. In this regard, the Equality Act 2010 did not change the law. Under s.217, with limited exceptions the Act does not apply to Northern Ireland.
