The Equality Act 2010 protected characteristics are the starting point for understanding discrimination law in England, Scotland and Wales. They identify personal characteristics that matter when deciding whether treatment is unlawful. But the list is only half the story: the rules also depend on what happened, where it happened and which type of discrimination is alleged.
Section 4 of the Act names nine protected characteristics. Together, they shape rights at work, in education, when accessing services and in other settings. They do not mean that every unfair experience is illegal, or that every characteristic receives identical protection everywhere.
What are the nine protected characteristics?
1. Age
Age covers particular ages and age groups, including younger and older adults. A recruitment policy automatically excluding applicants over a certain age may raise concerns. Some age-based treatment can be lawful if objectively justified or covered by an exception. Age discrimination rules for services generally do not protect people under 18.
2. Disability
Disability generally involves a physical or mental impairment having a substantial, long-term adverse effect on normal day-to-day activities. Conditions need not be visible. The law includes duties to make reasonable adjustments in relevant settings, such as adapting recruitment procedures or improving access to services. The effects of an impairment matter, not merely its diagnosis.
3. Gender reassignment
This protects people who propose to undergo, are undergoing or have undergone a process, or part of a process, of reassigning their sex by changing physiological or other attributes of sex. Surgery, hormones and a Gender Recognition Certificate are not prerequisites. Unfavourable treatment at work because someone is transitioning may be unlawful.
4. Marriage and civil partnership
Being married or in a civil partnership is protected by employment-related provisions, rather than across all services and education rules. An employer denying a promotion simply because an employee is married may be discriminating. Being single or divorced is not itself this protected characteristic.
5. Pregnancy and maternity
The law addresses unfavourable treatment because of pregnancy, pregnancy-related illness or maternity in covered circumstances. Withdrawing an opportunity because an employee is pregnant may be unlawful. Specific protected periods and rules apply, and a comparison with another worker is not always required.
6. Race
Race includes colour, nationality, and ethnic or national origins. It is broader than appearance or birthplace. Refusing to interview someone because of ethnicity is one example; a seemingly neutral rule may also create an unlawful racial disadvantage if it cannot be justified.
7. Religion or belief
Protection extends to religious beliefs, qualifying philosophical beliefs and having no religion or belief. It can affect dress requirements, religious observance and workplace conduct. Not every personal opinion qualifies as a philosophical belief, and particular cases may involve competing rights.
8. Sex
Sex is distinct from gender reassignment. In April 2025, the UK Supreme Court ruled in For Women Scotland v Scottish Ministers that “sex”, “woman” and “man” in the Equality Act refer to biological sex. The judgment did not remove trans people’s protection under gender reassignment or other applicable discrimination provisions. Single-sex services involve specific statutory rules and exceptions.
9. Sexual orientation
Sexual orientation covers orientation towards people of the same sex, opposite sex or either sex. Excluding a qualified employee from a client-facing role because they are gay may constitute direct discrimination. Protection does not depend on publicly disclosing one’s orientation.
How protected characteristics relate to discrimination
Not every decision affecting someone with a protected characteristic is unlawful. The conduct must fit a prohibited type of discrimination within a setting covered by the Act. The principal categories are direct discrimination, indirect discrimination, harassment and victimisation.
Direct discrimination usually means less favourable treatment because of a protected characteristic. Indirect discrimination can arise when a rule applied to everyone particularly disadvantages a protected group without sufficient justification. Harassment involves specified unwanted conduct; victimisation can arise when someone is penalised for making or supporting an equality complaint.
These categories have technical differences. Pregnancy and maternity rules are distinct, while harassment provisions do not apply to every characteristic in the same way. Understanding direct and indirect discrimination helps identify which test fits a particular incident.
A practical example: Saturday shifts
Imagine an employer introduces compulsory Saturday shifts for everyone. The rule looks equal on paper, yet it may particularly disadvantage staff whose religious observance prevents Saturday working. That raises a possible indirect religion or belief discrimination issue.
The employer must consider whether the rule pursues a legitimate aim and is a proportionate means of achieving it. Could rotating shifts or voluntary cover meet the business need? Neither the employee’s objection nor the employer’s preference automatically settles the matter.
Recording the rule, its practical effects, alternatives suggested and the employer’s response can help establish the facts.
Where the law applies—and its limits
Equality Act discrimination protections commonly arise in employment, education, housing, public functions, services and certain associations. However, the provisions and exceptions differ. Marriage and civil partnership protection is primarily employment-related; age rules for services generally concern adults. Disability law also imposes reasonable-adjustment duties in covered circumstances.
This framework applies to Great Britain, not Northern Ireland, which has separate discrimination legislation. The expression “protected groups law” is sometimes used informally, but can be misleading: direct discrimination may also involve a perceived characteristic or, in some circumstances, association with another person.
What to do if you believe discrimination occurred
Record what happened, relevant dates, messages, policies and witnesses. Identify the characteristic, treatment and setting rather than assuming unfairness alone proves a breach. Internal grievances may help, but formal legal deadlines can be short.
Acas offers workplace discrimination guidance; the Equality Advisory and Support Service can assist with wider equality questions. People dealing with disability-related problems may also benefit from guidance on reasonable adjustments at work. Seek legal advice promptly where facts or deadlines are disputed.
Frequently asked questions
Are there nine or ten protected characteristics?
There are nine under section 4 of the Equality Act 2010. Pregnancy and maternity are one characteristic, as are marriage and civil partnership, and religion or belief.
Does everyone have protected characteristics?
Yes. Everyone has an age and a sex, for example, and people with no religion may also be protected. This does not make every instance of unfair treatment illegal.
Does discrimination by association count?
Sometimes. Direct discrimination can arise through someone’s association with a person who has a protected characteristic, such as a family member. The precise legal provision matters.
Is the Equality Act the same across the UK?
No. Its main protected-characteristic framework applies in England, Wales and Scotland. Northern Ireland uses separate equality legislation.
Conclusion
The nine protected characteristics establish the foundation for equality act discrimination law. Identifying one is a useful beginning, but the legal assessment turns on the conduct, context, relevant exception and applicable legal test. That distinction helps people understand their rights without assuming every difficult experience is automatically a discrimination claim.
