Hiring a New Employee in the UK: Legal Checklist

Bringing in a new employee is a big milestone for any small business. It’s exciting - and it also comes with legal responsibilities you can’t afford to miss.

The good news? With a clear onboarding checklist and the right documents in place, you can hire confidently, comply with UK law, and set your new starter up for success from day one.

This guide walks you through the essential steps: from pre-employment checks and contracts, to pay, hours, policies and probation. We’ve kept it practical and plain-English so you can get on with growing your business.

What Counts As A “New Employee” Under UK Law?

Before anything else, confirm the person you’re hiring is actually an “employee” (as opposed to a worker or a genuine self-employed contractor). This matters because different rights and obligations apply depending on status - from holiday pay to unfair dismissal protections.

In simple terms:

• Employee: Works under a contract of employment with mutuality of obligation, must personally perform work, and you have significant control over how and when they work.
• Worker: Has fewer rights than employees but still gets certain protections (e.g. holiday pay and minimum wage).
• Self-employed contractor: Runs their own business, can substitute someone else to do the work, and bears the commercial risk.

Status is based on day-to-day reality, not what the paperwork says. If you’re unsure, it’s wise to review the employment status tests before you issue any offer.

Pre-Employment Checks And The Offer Stage

Once you’ve identified the right candidate, move through these key steps before their start date.

1) Right To Work And Basic Vetting

You must complete a compliant right to work check under UK immigration law (typically checking original acceptable documents or using the Home Office online service where applicable). Save evidence of the check before employment starts. Depending on the role, consider additional vetting (e.g. DBS checks for regulated roles, reference checks for roles handling sensitive data or money).

2) Pay, Budget And Benefits

Confirm the total compensation package. At a minimum, ensure pay meets National Minimum Wage/National Living Wage and check any role-specific requirements (for example, tips and tronc in hospitality). Agree how and when you’ll pay (monthly vs weekly), whether there’s commission, bonus eligibility, or overtime arrangements, and what benefits you’ll provide (pension auto-enrolment, private health, equipment).

3) Draft A Clear Written Offer And Contract

All employees are entitled to a written statement of particulars on or before day one, covering key employment terms. The best way to comply - and protect your business - is to issue a full Employment Contract that includes all required particulars and your commercial protections (confidentiality, IP ownership, restrictive covenants, notice, deductions, etc.).

Offer letters can set out headline terms and conditions, but the contract should be the binding document. Make sure the final contract is signed before they start work.

4) Equality And Fair Hiring

The Equality Act 2010 prohibits discrimination in recruitment. Avoid unlawful interview questions (e.g. about health, family plans or age) and ensure hiring criteria are job-related and consistently applied. If you’re adjusting the process for disabled candidates, record the adjustments you’ve made.

5) Payroll Set-Up

Register as an employer with HMRC (if you haven’t already), set up PAYE, collect P45/P46 starter details, and prepare to issue payslips. Factor statutory deductions (tax, NICs, student loans, pension) and be ready for statutory payments like sick pay and parental pay where eligibility criteria are met.

Essential Documents To Issue To A New Employee

Getting your documentation right is one of the simplest ways to stay compliant and avoid disputes. Here’s what to put in place on or before day one.

1) Employment Contract

A robust Employment Contract should cover (among other things):

• Job title, place of work (including home/remote arrangements), start date and continuous service
• Pay, pay cycle, hours, overtime rules, and deductions
• Holiday entitlement and bank holiday approach
• Probation length, review, and extension options
• Notice periods (both sides), and grounds for summary dismissal
• Confidentiality, intellectual property, and post-termination restrictions
• Data protection, monitoring and acceptable use terms

2) Staff Handbook And Policies

Policies help your team understand what “good” looks like and give you clear procedures if something goes wrong. Most small businesses benefit from a Staff Handbook covering:

• Disciplinary and grievance procedures
• Sickness absence and reporting
• Equal opportunities and anti-harassment
• Health and safety basics
• IT, communications and social media
• Flexible working requests
• Expenses and travel

Policies can sit separately from the contract (so you can update them more easily), but cross-refer in the contract so they’re binding. If you don’t need a full handbook yet, you can start with a targeted Workplace Policy and build from there.

3) Data Protection Notices

Under the UK GDPR and Data Protection Act 2018, you must provide employees with a privacy notice explaining how you collect and use their personal data (payroll, health data for sick pay, performance records, monitoring, etc.). Many businesses roll this into a new starter pack alongside IT and monitoring rules. If you’re collecting or processing employee data across different systems, consider a tailored approach using a Data Protection Pack.

4) Health And Safety Information

Every employer has duties under the Health and Safety at Work etc. Act 1974 to ensure, so far as reasonably practicable, the health and safety of workers. Provide relevant safety training, risk assessments, and emergency procedures. Keep records of inductions and training completed. If you operate in higher-risk environments (e.g. kitchens, warehouses, construction), invest more time in role-specific training.

5) Equipment, Access And Confidentiality

Issue equipment (laptop, phone, PPE), access credentials, and any passcodes carefully. Have your employee confirm receipt and agree to acceptable use, device security, and return-on-exit obligations. Make sure confidentiality and IP ownership are crystal clear in the contract before you share sensitive information.

Pay, Hours And Working Time Compliance

Getting pay and hours right from day one avoids unhappy staff and legal risk. UK law sets minimum standards you must follow.

Working Time And Rest

Employees are generally limited to an average 48-hour working week under the Working Time Regulations 1998 (unless they sign an opt-out), and are entitled to daily and weekly rest. Review your schedules and overtime expectations against the working time rules and ensure your onboarding covers rest and reporting procedures.

Entitlements to rest breaks vary by shift pattern and age. As part of induction, explain how staff should take and record breaks in compliance with employee break rules.

Minimum Wage And Deductions

Check the applicable National Minimum Wage/National Living Wage band for the employee’s age and role. Build in reviews when birthdays move staff into a higher band. If you plan to deduct for uniforms, training costs, or till shortages, ensure deductions are lawful, clearly set out in the employment contract, and won’t push pay below minimum wage in any pay period.

Overtime, Variable Pay And Benefits

If your business offers overtime, commission or bonuses, set out how they’re calculated and when they’re paid. Clarify whether overtime is compulsory or requires pre-approval, and whether it’s paid or taken as time off in lieu (TOIL). Keep a clear paper trail and make sure your payroll system reflects how these earnings are taxed and reported.

Holidays And Bank Holidays

Employees are entitled to at least 5.6 weeks’ paid holiday per leave year (pro-rated for part-time). State your leave year, how holiday accrues, and your approval process. Be clear on bank holiday expectations - whether they’re included in the entitlement and how rotas work if you’re open on public holidays.

Policies, Training And Health & Safety On Day One

Onboarding is more than a desk and a login. Use day one to set expectations, cover legal policies, and build good habits.

Mandatory Insurance And Safety

Most employers must hold Employers’ Liability insurance. Check your policy covers the new role, update your certificate display (physical or digital), and keep your insurer informed of changes. If you’re not sure whether your business is exempt, it’s worth reading up on Employers’ Liability Insurance requirements.

IT, Security And Confidentiality

Walk through your IT and security policies, including password rules, device encryption, phishing awareness, and data retention. Make sure your new starter understands confidentiality expectations, how to handle customer data, and who to contact if there’s a suspected data breach.

Fair Treatment And Culture

Introduce your equal opportunities and anti-harassment policies. Explain your standards for professional conduct (including social media) and how to raise a concern. Early clarity on culture and behaviour goes a long way to prevent problems later.

Role-Specific Training

Plan onboarding activities that help the employee do their job safely and well. This might include shadowing, supervised tasks, and competency assessments. Keep a training log - it’s helpful for performance reviews and is a key record if you ever need to show you’ve taken reasonable steps on safety or compliance.

Managing Probation, Performance And Early Issues

Probation is your chance to confirm the role is a good fit - for both sides. Treat it as a structured, supportive period rather than a tick box.

Set A Clear Probation Period

Most small businesses set probation at 3–6 months. State the length, review points, and any extension rights in the contract. Regular check-ins and written feedback are best practice and make decisions at the end of probation much easier. For a practical overview, see common rules and pitfalls around probation periods.

Performance Expectations And Support

Share objective goals early, agree how performance will be measured, and give timely feedback. If concerns arise, act quickly - provide informal coaching first, then escalate to formal processes only if needed. Where performance issues persist after probation, a fair, documented approach (including support and timescales) is essential. A structured plan such as a performance improvement plan can help in the right cases, keeping things fair and transparent.

Attendance And Sickness

Explain how to report sickness, when fit notes are required, eligibility for Statutory Sick Pay, and how return-to-work conversations will happen. Keep records of absences and maintain confidentiality when handling health information.

Extending Probation Or Ending Employment

If performance is borderline but improving, you might extend probation in line with the contract. If ending employment, follow your contractual and legal obligations: give the correct notice (or pay in lieu, if permitted), pay outstanding holiday, and provide a P45. Keep your rationale and process documented - fairness and consistency are key.

Practical Onboarding Checklist For Your New Employee

Use this as a quick reference to keep your onboarding on track. Every business is different, but these are the common steps that keep you compliant and organised.

• Confirm status: employee vs worker vs contractor (use the employment status tests).
• Run right to work checks and store evidence securely.
• Prepare offer letter and issue a signed Employment Contract before start date.
• Set up PAYE, auto-enrolment pension and payroll details (P45/P46).
• Provide privacy notice and data protection information (consider a Data Protection Pack).
• Issue your Staff Handbook (or priority Workplace Policies) and get acknowledgements.
• Check Employers’ Liability Insurance and display the certificate.
• Provide a safety induction and any role-specific training; log completion.
• Confirm working hours, opt-out (if applicable), and align schedules with working time rules and employee breaks.
• Issue equipment and access; record serial numbers and acceptable use acknowledgements.
• Set probation length and review dates; diarise check-ins.

Common Legal Pitfalls When Hiring Your First Employee

Here are some mistakes we often see - and how to avoid them.

• No written contract on day one: This risks non-compliance and leaves you exposed on confidentiality, IP and notice. Always issue a signed Employment Contract before the start date.
• Unclear working hours and overtime: Ambiguity leads to disputes and potential working time breaches. Be explicit about hours, breaks, overtime pay or TOIL, and scheduling processes.
• Missing policies: Without a Staff Handbook or core policies, it’s harder to manage conduct, grievances or safety concerns fairly.
• Weak onboarding records: If there’s a later dispute, you’ll want proof of training, right to work checks, and policy acknowledgements.
• Poor data practices: Employee data is still personal data. Document your lawful basis, minimisation, retention, and security - a fit-for-purpose Data Protection Pack helps you put this in order.
• Ignoring insurance: Employers’ Liability is a legal requirement for most employers - fines apply if you’re not covered.

If any of this feels overwhelming, don’t stress - a quick setup with the right documents and processes will save you time and headaches later.

Key Takeaways

• Confirm the person’s status as an employee (not a worker or contractor) using the employment status tests - status drives your legal obligations.
• Complete right to work checks, set up PAYE and pensions, and issue a signed Employment Contract on or before day one.
• Provide a privacy notice and core policies - a Staff Handbook and tailored Data Protection Pack help you stay compliant and consistent.
• Align rotas and breaks with the working time rules and employee break rules, and keep clear payroll records.
• Set probation with scheduled check-ins, document training, and address performance concerns early and fairly.
• Hold valid Employers’ Liability Insurance and keep your safety induction and risk assessments up to date.
