Equality Act 2010 Explained: What UK Employers Need to Know

The Equality Act 2010 is the core piece of discrimination law covering England, Scotland and Wales, and it sits behind most of the workplace equality obligations finance and HR teams deal with day to day — from reasonable adjustments to gender pay gap reporting, and it underpins much of the equality and diversity content in Learnsignal's CPD-accredited compliance courses. It doesn't apply to Northern Ireland, which has its own separate discrimination legislation, or to the Republic of Ireland, which is covered by the Employment Equality Acts 1998–2015. This guide covers what the Act actually says, so you have the legal framework in place before looking at any specific compliance topic in more depth.

The nine protected characteristics

The Act makes it unlawful to discriminate against someone because of any of nine protected characteristics: age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex, and sexual orientation. These apply across employment, but also in areas like the provision of services and education. Several of these characteristics — disability, pregnancy and maternity, and sex in particular — come up most often in day-to-day employer compliance work, which is why they tend to have their own dedicated guidance.

The four types of unlawful discrimination

The Act defines discrimination more broadly than most people expect, covering four distinct forms. Direct discrimination is treating someone less favourably because of a protected characteristic — intent doesn't matter, only the effect. Indirect discrimination happens when a policy or practice that applies to everyone puts people with a particular characteristic at a disadvantage; this can sometimes be lawful if an employer can show it's a proportionate way of achieving a legitimate aim. Harassment is unwanted conduct related to a protected characteristic that violates someone's dignity or creates an intimidating, hostile or offensive environment — again, effect matters more than intent. Victimisation is treating someone unfairly because they've made or supported a discrimination complaint, such as raising a grievance or acting as a witness in someone else's.

Equal pay and positive action

Sitting alongside the four main forms of discrimination, the Act also contains the UK's equal pay provisions, giving men and women a right to equal pay for equal work, work rated as equivalent, or work of equal value, regardless of job title. This is the legal backbone behind gender pay gap reporting obligations for larger employers. The Act also permits — but doesn't require — limited positive action, allowing employers to take proportionate steps to address under-representation or disadvantage linked to a protected characteristic, provided the action doesn't amount to simply selecting a candidate because of that characteristic.

Who the duties apply to

The Act applies to all employers in Great Britain, regardless of size, sector or turnover — there's no small-business exemption. Duties extend beyond employees to job applicants and workers more broadly. For disability specifically, the Act creates a positive duty to make reasonable adjustments, rather than simply a duty not to discriminate — meaning employers have to act, not just avoid certain behaviour. The Equality and Human Rights Commission (EHRC) is the statutory body responsible for enforcing the Act and publishes statutory codes of practice that tribunals refer to when interpreting it.

How this shows up in practice

Most day-to-day compliance work sits underneath this Act rather than referencing it directly. If you're building out training or policy in a specific area, it's worth starting with the characteristic or scenario that applies: our guides to disability inclusion and reasonable adjustments, pregnancy and maternity discrimination, and gender pay gap reporting each work through one area of the Act in practical detail. Treat this page as the legal foundation those sit on top of.

FAQs

Does the Equality Act 2010 apply in Northern Ireland or Ireland?
No. It covers England, Scotland and Wales, with only a handful of specific sections extending to Northern Ireland. Northern Ireland has its own discrimination legislation, and the Republic of Ireland is covered separately by the Employment Equality Acts 1998–2015, which use a different structure of protected grounds.

Can indirect discrimination ever be lawful?
Yes, if an employer can objectively justify the policy or practice as a proportionate means of achieving a legitimate business aim. This is a genuine legal test, not a formality, and the burden is on the employer to demonstrate it.

Is there a minimum company size the Act applies to?
No. Unlike some employment protections that scale with headcount, the Equality Act 2010's discrimination provisions apply to every employer in Great Britain regardless of size.

What's the difference between the Equality Act and the Worker Protection Act?
The Equality Act 2010 sets out what discrimination and harassment are and who's protected. The Worker Protection Act adds a specific, additional duty on employers to take reasonable steps to prevent sexual harassment before it happens, rather than just responding to it after the fact — it builds on the Equality Act rather than replacing any part of it.
