How To Employ Someone In The UK: Step-By-Step Guide

Hiring your first (or next) team member is a huge milestone. It’s also one of those moments where the “business” suddenly starts feeling very real - because once you bring someone into your team, you’re taking on legal responsibilities as an employer.

If you’ve been Googling how to employ someone in the UK, you’re not alone. A lot of small business owners and startup founders worry they’ll miss a key step, set things up incorrectly, or accidentally create risk around pay, working hours, holidays, or dismissal.

The good news is: you don’t need to overcomplicate it. If you approach hiring like a checklist (and get your key documents right), you can build a compliant setup that protects your business from day one.

Step 1: Decide What “Employing Someone” Actually Means For Your Business

Before you put out a job ad or agree a start date, it’s worth getting clear on the legal status you’re offering. In everyday language, business owners often say “employee” to mean “someone who works for me”. Legally, it can be more nuanced - and the right answer is very fact-specific.

Broadly, you might engage someone as:

• An employee (works under a contract of employment, has stronger employment rights, and you’ll have more obligations as an employer)
• A worker (often more casual or flexible, but still entitled to key protections like holiday pay and minimum wage)
• A self-employed contractor (runs their own business and provides services to you under a services agreement)

This matters because getting status wrong can create real legal and financial risk (for example, if someone you treat as a contractor later claims they were an employee and brings a claim for holiday pay or unfair dismissal).

Practical Tip For Small Businesses

Status isn’t decided by what you call the relationship - it depends on the reality of how the work is done. If you control how, when and where they work, require them to do the work personally, and they’re integrated into your business (your tools, your processes, your team), you’re often looking at employment (or worker) status.

If you’re unsure, it’s worth getting advice early - because the status decision flows into pay, tax, policies, and how you manage performance later.

Step 2: Set Up The “Employer Admin” (PAYE, Payroll And Right To Work)

Once you’ve decided you’re employing someone (rather than engaging a contractor), you’ll need to set up the essentials that allow you to pay them lawfully and keep proper records.

Register As An Employer With HMRC (PAYE)

In most cases, you’ll need to register for Pay As You Earn (PAYE) so you can:

• deduct Income Tax and National Insurance from wages
• pay employer National Insurance contributions (where applicable)
• report payroll information to HMRC

Many small businesses use payroll software or an accountant/bookkeeper for this. Even if you outsource payroll, remember: you still carry the legal responsibility for paying people correctly and on time.

Note: PAYE, payroll and National Insurance can be technical, and the right approach depends on your circumstances. This article is general information and isn’t tax or financial advice - if you’re unsure, it’s sensible to check with an accountant or payroll professional.

Check The Legal Right To Work In The UK

Before someone starts work, you must carry out a right to work check. This is a key compliance step that protects your business from civil penalties for illegal working.

Right to work checks usually involve verifying acceptable identity documents (or using an online check where permitted) and keeping a compliant record.

Get Ready For Workplace Pensions (If Applicable)

Most employers have duties under auto-enrolment pension rules. Whether you need to auto-enrol your new hire will depend on their age and earnings, but you should assume pensions are part of the setup unless you’ve confirmed otherwise.

Note: Workplace pensions and auto-enrolment are regulated areas and can depend on the details. This is general information only (not pensions advice) - your payroll provider, accountant or pension provider can help you confirm what applies.

Set Up A Basic Record-Keeping System

Even for one hire, you should be ready to store:

• their contract and onboarding documents
• right to work check records
• payroll records and pay slips
• holiday and sickness records
• any disciplinary, performance, or grievance notes (if issues arise later)

Good record-keeping is one of the simplest ways to reduce risk if there’s ever a dispute.

Step 3: Make A Clear Offer And Confirm The Key Terms In Writing

One of the most common mistakes we see is founders moving quickly (because they’ve finally found the right person) and skipping the “paperwork” until later.

But if you want to employ someone properly, this is the turning point: set expectations clearly and early.

Start With A Written Offer

Your offer should clearly cover the commercial basics, such as:

• job title and start date
• pay (salary or hourly rate) and pay frequency
• hours and place of work (including remote/hybrid expectations)
• holiday entitlement
• notice periods
• any conditions (e.g. references, right to work)

Be careful with “informal” offers over email or messaging. In many situations, emails can form part of what you’ve agreed - so accuracy matters.

Use A Proper Employment Contract (Not A Generic Template)

A well-drafted Employment Contract does more than confirm pay and hours. It’s also how you protect your business on issues like:

• confidentiality (especially if they’ll access sensitive customer, pricing, or product info)
• intellectual property (so work created in the role belongs to your business)
• post-employment restrictions (where appropriate and enforceable)
• probation and performance management
• disciplinary and grievance processes

Even a “simple” hire can become legally complex if things don’t work out. A tailored contract reduces uncertainty and gives you a clearer path if you need to address performance issues later.

Set A Sensible Probation Period

Probation isn’t legally required, but it’s a practical tool for startups and small businesses because it creates a structured review point early on.

Your contract should be consistent with how you plan to run probation, including length, review process, and notice terms. If you want your probation process to be enforceable and fair, it’s worth understanding how probation periods generally work in the UK.

Step 4: Put The Right Workplace Policies In Place (So You’re Protected From Day One)

When you employ someone, you’re not just paying for work - you’re running a workplace. That means you need clear rules and processes that set expectations and reduce disputes.

For many small businesses, the easiest way to do this is through a Staff Handbook and a few core policies.

Staff Handbook And Core Policies

A Staff Handbook can be a simple, scalable way to cover the day-to-day expectations that don’t always sit neatly in the contract.

Common policies include:

• sickness and absence reporting
• holiday booking processes
• code of conduct and disciplinary rules
• anti-bullying and harassment expectations
• hybrid/remote working expectations
• use of company IT and systems

Working Time, Breaks And Pay Compliance

If you’re running a small team, it’s easy to accidentally drift into habits like “everyone just works until the job is done”. But working time rules still apply, and these are common areas where employers get caught out.

At a minimum, you should understand how rest breaks work under UK law - especially if you have shift workers or busy periods - and ensure your approach aligns with the rest and lunch break rules.

You should also be aware of the broader framework around maximum weekly working hours and opt-outs under the Working Time Regulations.

Data Protection And Monitoring (Especially For Remote Teams)

If your employee will use work systems, handle customer data, or use personal devices for work, you need to think about privacy and UK GDPR compliance.

This doesn’t mean you can’t monitor business systems at all - but you should do it transparently and proportionately, with the right documentation in place. If you’re considering monitoring browsing activity or work devices, it’s worth understanding the practical boundaries around monitoring employees’ computers.

Where relevant, an acceptable use policy and clear internal privacy approach can help you set expectations and reduce the risk of complaints.

Step 5: Onboard Properly And Manage The Relationship Fairly (Performance, Sickness And Ending Employment)

Once your new hire starts, the “how to employ someone” question shifts from setup to management. This is where good habits and fair processes really matter.

Run A Simple, Documented Onboarding

Onboarding doesn’t need to be complicated, but it should be consistent. Consider including:

• a signed contract before or on day one
• training on systems, security, and confidentiality
• a clear role description and initial objectives
• a probation review schedule (for example, at 4 weeks, 8 weeks, and at the end of probation)

This is also a good time to make sure your new hire understands boundaries around confidential information. If you ever need to enforce confidentiality later, it’s much easier if you’ve communicated expectations clearly from the start.

Pay, Holiday And Sickness: Keep It Consistent

Small businesses often run into issues not because they’re trying to do the wrong thing, but because they handle situations inconsistently.

For example:

• letting one person take holiday without approval but refusing another
• paying sickness differently depending on who it is
• changing someone’s hours informally without confirming it properly

Even with a small team, consistency is a big part of being a fair (and defensible) employer.

Performance Issues: Address Them Early And Document Them

Performance management is one of those areas founders avoid because it feels awkward. But leaving issues unaddressed is usually what turns a manageable situation into a legal risk.

If performance becomes a concern, you’ll generally want to:

• raise concerns early, privately, and with examples
• give the employee an opportunity to respond
• set clear expectations and timeframes for improvement
• document meetings and outcomes

For more structured situations, a Performance Improvement Plan (PIP) can help - but it needs to be handled carefully to avoid turning into a tick-box exercise. If you’re heading in that direction, it may help to understand how PIPs are typically run lawfully in the UK.

Ending Employment: Don’t Leave It To A Last-Minute Decision

Sometimes it doesn’t work out - especially in early-stage businesses where roles evolve quickly.

If you need to end employment, the “safe” approach is usually the “fair” approach:

• follow the contract (especially notice provisions)
• follow a reasonable process (particularly if dismissal is linked to conduct or performance)
• be mindful of discrimination risks (which can apply from day one of employment)

Even if someone has short service, a rushed dismissal can still create issues (for example, if it relates to protected characteristics, whistleblowing, or asserting statutory rights). This is one of the biggest reasons it’s worth getting your contract and policies right upfront - they give you a clearer roadmap when things get difficult.

Key Takeaways

• Start by confirming status (employee vs worker vs contractor), because the legal obligations and risks are very different - and the correct status depends on the facts.
• Register and set up payroll properly (PAYE, record-keeping, pensions where applicable) before the employee starts. (For tax/payroll specifics, check with an accountant or payroll provider.)
• Carry out right to work checks every time, and keep compliant records to protect your business.
• Use a tailored Employment Contract to clearly set pay, hours, notice, confidentiality, IP ownership, probation, and key workplace expectations.
• Back your contract up with practical policies (often through a Staff Handbook), so you have clear rules on leave, conduct, IT use, and day-to-day processes.
• Manage performance and workplace issues early, consistently, and with documentation - waiting usually increases risk.
• When in doubt, get advice early, because it’s far easier (and cheaper) to set things up correctly than to fix problems after a dispute has started.
