What are my legal obligations as an employer when growing a small team in the UK?

When you took on your first couple of employees, you probably cobbled things together — a contract downloaded from somewhere, a rough idea of what you had to pay, and a handshake understanding of how things would work. That’s normal. But if you’re now building a team of five, six, seven people, the informal approach that worked then is quietly becoming a liability.

This guide is for limited company directors who are actively growing their team and want to make sure their employment setup is actually protecting them — not just ticking a box.

Why what worked at two people doesn’t hold at eight

The legal obligations of being an employer don’t scale with headcount — they apply from the moment you take on your first member of staff, and the risk of getting things wrong grows significantly as your team does.

With one or two employees, a missing policy or an inconsistent process is unlikely to cause immediate problems. With a team of eight, inconsistency becomes grounds for a grievance. An undocumented disciplinary process becomes a tribunal risk. A contract that was roughly right for one person may not hold up applied across a team with different roles, hours, and arrangements.

The Employment Rights Act is also raising the stakes for small employers. From April 2026, the qualifying period for unfair dismissal protection reduces from two years to six months — meaning employees can bring a claim significantly earlier in their tenure than before (gov.uk, Employment Rights Act 2025). For a growing team where you’re still working out who’s the right fit, that’s a meaningful shift in your exposure.

The true cost of employment is also regularly underestimated at this stage. Beyond salary, each employee carries employer National Insurance contributions (15% on earnings above £5,000 per year from April 2025), workplace pension contributions, statutory sick pay, and holiday pay (gov.uk, Employer National Insurance). For a team of eight, these additions represent a significant proportion of your total employment cost — and if your contracts or policies aren’t clearly drafted, disputes over any of them become more likely.

There are five things every employer with a growing team needs to have clearly in place

1. Written contracts for every employee, drafted for their actual role Every employee must receive a written statement of employment particulars from day one — this is a legal requirement under the Employment Rights Act 1996. A contract that doesn’t reflect the actual working arrangement (hours, role scope, notice periods, probation terms) gives you limited protection if a dispute arises. If you’re using the same employment contract you drafted for your first hire across different roles, it’s worth reviewing.

2. An employee handbook that reflects how you actually operate A handbook is your primary defence in a disciplinary or grievance situation. It sets out your policies on conduct, absence, performance management, and grievances — and gives you a consistent, documented process to point to. Without one, every people situation becomes a judgement call made without a framework, which is where decisions get challenged.

3. A clear understanding of employment status for everyone working for you As your team grows, it’s common to use a mix of employees, workers, and contractors. HMRC and employment tribunals look at the substance of the working relationship, not the label on the contract — and misclassification carries backdated tax liability as well as employment rights exposure. If you’re unsure how to categorise anyone working for your business, Citation’s guide to employment status covers the key distinctions, or see ACAS on employment status for the statutory framework.

4. Consistent processes for probation, performance, and absence The most common reason employment tribunal claims succeed against small employers isn’t that the dismissal was wrong — it’s that the process wasn’t followed. The ACAS Code of Practice on Disciplinary and Grievance Procedures is the benchmark employment tribunals use. Having a process, applying it consistently, and keeping written records is what protects you. The 10 most common disciplinary mistakes small employers make are more avoidable than most directors realise.

5. A written health and safety policy As an employer, you have a duty of care to everyone who works for you under the Health and Safety at Work Act 1974. If you have five or more employees, you are legally required to have a written health and safety policy (HSE). This covers stress and workload as well as physical risk.

At what point does managing HR yourself stop making sense?

Most directors at the 5–10 employee stage manage HR themselves, alongside everything else — and that works until it doesn’t. The point at which it stops working is usually a people situation that escalates faster than expected.

The question isn’t whether you can handle day-to-day HR. It’s whether you have the right setup underneath you so that when something difficult happens — a grievance, a disciplinary, a redundancy — you’re dealing with the situation rather than scrambling to work out what process you should have been following.

For Citation clients — businesses at exactly this stage — the data is clear: they are 93% less likely to receive a tribunal claim than the national average (2025 client data vs national averages). That’s not because their employees are different. It’s because they have the right contracts, policies, and advice in place before something goes wrong, not after.

Common questions from directors building their first team

Do I need a written contract for every member of staff? Yes — all employees must receive a written statement of employment particulars on or before their first day. This is a legal requirement under UK employment law, covering job title, pay, hours, holiday entitlement, notice periods, and sick pay arrangements. Using a generic template that hasn’t been reviewed for your specific roles carries risk.

What’s the real cost of taking on an employee beyond their salary? For each employee, expect to add employer National Insurance contributions (15% on earnings above £5,000 per year from April 2025), a minimum 3% employer pension contribution, statutory sick pay, and 5.6 weeks’ paid holiday for full-time staff (gov.uk). For a mid-range salary of £30,000, the true employment cost typically runs £4,000–£6,000 above the headline figure.

How does the Employment Rights Act affect me as a small employer? From April 2026, the qualifying period for unfair dismissal protection reduces from two years to six months, meaning employees can bring a claim considerably earlier in their tenure. This makes clear probation processes and documented performance conversations significantly more important for growing teams. Citation’s Employment Rights Act hub covers what’s changing and when.

What happens if I’ve been treating someone as self-employed but they’re actually an employee? HMRC and employment tribunals look at the reality of the working relationship — if someone works exclusively for your business, carries out work personally, and operates under your direction, they are likely an employee regardless of their contract label. This can result in backdated tax and NI liability and exposure to employment tribunal claims. See Citation’s guide to employment status if you’re unsure about anyone working for you.

At what point should I get professional HR support rather than handling this myself? The practical trigger is usually when you have enough people that inconsistency in how you manage them creates risk — or when you’re facing a situation where the process matters as much as the outcome. Getting support before those situations arise is significantly less stressful and usually less expensive than addressing problems after they escalate.
