Workplace dress codes are back on the agenda for UK employers. After years of remote and hybrid working blurred the line between office and home, many businesses are revisiting what their staff should wear. Some professional-services firms have tightened standards; others have moved to a “dress for your day” approach. For small-business owners, the question is not whether a dress code is fashionable, but whether it is useful.
A policy that is clear, fair and tied to your brand can build trust with customers and save awkward conversations. One that is rigid, outdated or focused on appearance rather than outcomes can demotivate a team and expose you to discrimination claims. Here is how to decide what is right for your business.
Do small businesses need a dress code?
In law, UK employers are entitled to set a dress code, provided it is reasonable and does not discriminate. Under the Equality Act 2010, any requirement must not disadvantage staff because of sex, gender reassignment, religion or belief, disability, age or pregnancy. Acas guidance reminds employers that rules should be applied consistently and justified by the job, not by personal taste.
The issue was thrown into the spotlight in 2016, when agency receptionist Nicola Thorp was sent home for refusing to wear high heels at work. Her parliamentary petition gathered more than 150,000 signatures and led to a Commons inquiry. The government concluded that existing discrimination law was adequate, but the case is a sharp reminder that gender-specific dress requirements must be objectively justified and applied proportionately.
Health-and-safety law adds another layer. The Health and Safety at Work etc. Act 1974 and related regulations may require specific clothing, footwear or personal protective equipment in construction, manufacturing, catering, healthcare and cleaning. In these sectors, dress rules are not about image; they protect staff and customers.
For customer-facing small businesses, a uniform or simple dress code can be a practical branding tool. Tradespeople, caterers, taxi firms, salons and retail staff often find that a consistent look signals reliability and professionalism. Clients can identify employees quickly, and the business looks cohesive. In premium service businesses, staff presentation can reinforce the brand values you want customers to associate with you.
That does not mean every business needs a lengthy manual. In many small firms, especially those where staff work behind the scenes or in creative roles, rigid rules can do more harm than good. Customers who pay for originality may expect the people delivering it to look individual. Professionals such as consultants and lawyers need to demonstrate judgment, and an overly prescriptive code can undermine that message. In hybrid and remote teams, the question becomes even more nuanced: does a dress code apply to video calls, and if so, to what degree?
As your business grows, informal “common sense” may no longer be enough. An events planner we spoke to, Sue, started with no rules at all. As she took on staff, she introduced a short, practical note: no holes, stains or torn clothing. She disliked having to state the obvious, but the brief guideline prevented misunderstandings and gave her a neutral way to raise issues when they arose.
Setting a dress code that works
Where a dress code is necessary, the best policies are short, inclusive and developed with the team. Rather than dictating skirt lengths or sock colours, focus on what the business needs staff to communicate. A short development session on brand values and customer expectations can help employees understand why presentation matters, without making them feel policed.
Involving staff in drafting the policy also reduces the risk of discrimination. Requirements to wear high heels, specific hairstyles or make-up have been successfully challenged because they disproportionately affect women. Rules that ignore religious dress, cultural hair practices, disability-related footwear or menopause-friendly clothing can exclude talented people. If you are unsure, Acas and the Equality and Human Rights Commission publish free guidance, and it is worth reviewing your policy alongside your employing people procedures.
A good dress code should answer a few simple questions: What is the business reason for the rule? Where does it apply, including on video calls or client sites? What is clearly not acceptable? How can staff request adjustments? And who will enforce the policy fairly?
Practical support matters too. If you require a uniform, provide it or a reasonable allowance. If staff need specialist footwear or PPE, supply it in a range of sizes and fits. For roles where safety is critical, train employees on why the rules exist. In office-based roles, a “dress for your day” guideline—smart for client meetings, relaxed for focused work—can give autonomy while maintaining standards.
Wellbeing and inclusion should sit at the heart of the policy. A dress code that allows comfortable, temperature-regulating fabrics and flexible footwear can support staff experiencing menopause, pregnancy or long-term health conditions. Small adjustments cost little and send a clear signal that you value people for their contribution, not their conformity.
Finally, review the policy regularly. Business needs, customer expectations and social norms change. What looked professional a decade ago can look dated or exclusionary today. A short annual check, perhaps as part of your wider equality and diversity review, will keep your dress code relevant and legally sound.
There is no universal answer to whether your small business needs a dress code. In safety-critical or customer-facing roles, clear standards protect your staff and reinforce your brand. In creative, technical or remote teams, trust and flexibility may serve you better. The goal is not to control how people look, but to give them the clarity and support they need to represent your business well. Get that balance right, and your team will not only look the part—they will feel it too.
