Employers in the UK can set standards of dress, but those standards sit inside equality law. This article explains what a workplace dress code can reasonably ask of men, which protections apply, and how a rule about ties or suits differs from one that raises a legal problem.
Most men will meet a dress code at some point, whether it is an unwritten expectation of a jacket in a client-facing office or a written policy covering uniform, footwear and grooming. The rules are rarely dramatic. But they shape what men wear for a large share of their waking hours, and a poorly designed one can disadvantage people in ways its authors never intended.
Is there a law about dress codes at all?
There is no single statute devoted to what people wear at work. Instead, dress codes are tested against the general discrimination rules in the Equality Act 2010. The GOV.UK guidance on discrimination says it is against the law to discriminate against anyone because of nine listed characteristics:
- age
- gender reassignment
- being married or in a civil partnership
- being pregnant or on maternity leave
- disability
- race, including colour, nationality, ethnic or national origin
- religion or belief
- sex
- sexual orientation
Acas, the public body that advises on workplace relations, makes the same point in its guidance on inclusive workplaces: employers should check that their dress code does not discriminate against any protected characteristics. In other words, an employer is free to have a code, and the legal question is whether the code or the way it is applied treats someone unfairly because of one of those characteristics.
What is the difference between direct and indirect discrimination in a dress code?
The Equality Act describes two main forms, and both can arise in a dress code.
Direct discrimination. Under section 13 of the Act, a person discriminates against another if, because of a protected characteristic, they treat the other person less favourably than they treat or would treat others. A rule that applied only to one sex and left the other without a comparable expectation is the kind of thing that invites a closer look.
Indirect discrimination. Section 19 covers a rule that looks neutral but bites unevenly. The Act says a provision, criterion or practice is discriminatory in relation to a protected characteristic if the employer applies it to people who do not share that characteristic, it puts people who share the characteristic at a particular disadvantage, it puts the individual at that disadvantage, and the employer cannot show it to be a proportionate means of achieving a legitimate aim.
That last phrase, a proportionate means of achieving a legitimate aim, is the test employers have to meet. A legitimate aim might be safety, hygiene or presenting a professional image to customers. Proportionate means the rule goes no further than needed to achieve it.
A worked illustration
Consider a hypothetical office rule: “All staff must be clean-shaven.” It looks neutral and could be justified in a role that involves a tight-fitting respirator mask. In a role with no such requirement, the same rule might put some religious staff at a disadvantage, and the employer would then have to show a proportionate justification. The rule is the same; whether it holds up depends on the job, the reason and the alternatives. This is an illustration of how the test works, not a statement about any particular case.
Can an employer require men to wear a tie or suit?
Generally an employer can set a standard of smartness, and a requirement for a jacket or tie in a formal setting is the sort of standard many organisations choose. What matters is how the standard is framed and applied. The principles from the Equality Act point to a few practical questions:
- Is there a clear reason for the rule, such as customer-facing work or a safety requirement?
- Does the rule apply in a comparable way to everyone, even if the details differ between roles?
- Is there a way to adjust it for someone whose religion, disability or circumstances make it difficult?
Where a rule is purely a matter of taste, it is easier to defend if it is described in terms of the standard to be met (“business dress”) rather than a list of specific garments. The same logic applies to the broader world of formal dressing: our explainer on how a suit should fit covers what smart dress involves, and our guide to what a tailor can and cannot alter is useful for anyone asked to meet a standard on a budget.
What about heat, ties and jackets in summer?
Acas has specific advice for hot weather. On its hot-weather page, it says employers are not under any obligation to relax their uniform or dress code requirements during hot weather, but adds that where possible it may be advisable for employers to relax the rules for wearing ties or suits. It also states that there is no legal maximum working temperature, and it points to the Health and Safety Executive’s advice that the temperature in indoor workplaces should be reasonable.
For men in formal workplaces, this is a useful reading of the position. The law does not force a relaxed summer code, but the guidance clearly leans toward flexibility, and employers also have a general duty of care to keep working temperatures reasonable, including for home workers.
| Question | What Acas says |
|---|---|
| Must a dress code be relaxed in hot weather? | No obligation to relax uniform or dress code requirements |
| Is relaxing ties and suits sensible? | Where possible, it may be advisable |
| Is there a legal maximum temperature? | No; the temperature should be reasonable |
How do religion, disability and gender reassignment fit in?
Three of the protected characteristics come up repeatedly in dress code disputes, and the sources above give a sense of how they are handled.
Religion or belief. A dress rule that restricts religious clothing or grooming is the classic indirect discrimination scenario described above. The employer’s task is to link any restriction to a real need and show that it is proportionate.
Disability. GOV.UK explains that employers must make reasonable adjustments for workers with disabilities or physical or mental health conditions, and that this applies to all workers, including trainees, apprentices and contract workers. In a dress code context, that could mean a different fastening, fabric or footwear arrangement. The GOV.UK examples of adjustments range from changing equipment to altering the way work is done, which shows how broad the idea is.
Gender reassignment. Acas guidance on preventing gender reassignment discrimination says it is reasonable for an employer to set standards of dress for their organisation. It then adds that dress codes and uniforms should be flexible and should allow employees to dress in a way they feel comfortable with, noting that what someone feels comfortable with might change as they transition.
Why does the way a code is written matter?
Wording is where many problems start. A code that says “men must wear a tie” invites the question of what is required of everyone else and whether the distinction is justified. A code that says “dress should be smart and appropriate for client meetings, and safe for the work being done” sets out the aim and leaves room for different people to meet it in different ways.
A well-drafted policy usually does several things:
- It states its purpose, such as safety, hygiene or client-facing work.
- It describes the standard rather than listing garments, wherever possible.
- It says how to ask for an adjustment and who decides.
- It applies in the same spirit to every role and every employee.
- It is communicated before problems arise, not after.
The red-carpet world offers a useful contrast. Event dress codes such as “black tie” are conventions with a long history, and our piece on red carpet dress codes shows how they work as shared shorthand. A workplace code is different in one crucial way: it is a condition of employment, so the stakes are higher and the law applies.
What should men do if a dress rule causes a problem?
Practical steps are usually sensible and low-key. Reading the written policy comes first, since many organisations have one. If a rule is difficult because of a disability, religion or belief, or a gender reassignment, raising it with a manager or HR is the normal route, and a reasonable employer will consider alternatives. Acas publishes guidance for both employees and employers, and the GOV.UK guidance on discrimination sets out the wider framework of rights.
Day-to-day garment care is a separate matter, but a strict dress code often goes hand in hand with careful maintenance, and our guide to reading clothing care labels is a good companion for anyone building a workwear rotation.
Conclusion: a code is a standard, not a costume
A workplace dress code is lawful when it has a sound purpose, is applied fairly and leaves room for justified adjustments. The Equality Act gives the structure: no less favourable treatment because of a protected characteristic, and no neutral-looking rule that disadvantages a group unless it is a proportionate way to achieve a legitimate aim. Acas adds the practical gloss, from the advice to check for discrimination to the suggestion that ties and suits can be relaxed in the heat.
For men, the useful habit is to treat the code as a standard to be met rather than a list of garments to be bought, and to ask about adjustments early if the standard is difficult to meet.
