The Employee Handbook: What UK Employers Need to Know in 2025
Introduction
An Employee handbook is a cornerstone of good employment practice in the UK. While they are not strictly required by law, they provide a structured way for employers to set out workplace policies, explain procedures, and outline expectations for staff. In 2025, new employment legislation came into force, making the importance of maintaining an up-to-date handbook greater than ever. Handbooks protect both employers and employees: they reduce the risk of disputes, ensure compliance with legal obligations, and create a culture of clarity and fairness. This guide explains what an employee handbook is, which policies are mandatory, what’s recommended, and how requirements vary depending on company size.
What Is an Employee Handbook?
An employee handbook is a central document that brings together a company’s key workplace policies, procedures, and guidance for staff. Unlike an employment contract, which is a legally binding agreement between employer and employee, a handbook is usually non-contractual. This means it can be updated as laws or internal practices change without needing to renegotiate contracts. The handbook serves as a practical reference point: employees can check policies on leave, flexible working, or disciplinary procedures, while managers have a framework to apply rules consistently. For many organisations, the handbook is also a tool to communicate company values, workplace culture, the company's mission and behavioural expectations.
In short: a handbook is your company’s reference manual, ensuring everyone understands the rules, rights, and responsibilities that shape daily working life. This document outlining relevant policies provides clarity, strengthens the employment relationship, and reduces the risk of misunderstandings.
Are Staff Handbooks Legally Required in the UK?
In the UK, there is no absolute legal requirement for employers to have an employee handbook. However, many of the policies typically contained within a handbook are required by law. For example, written disciplinary and grievance procedures, equal opportunities policies, and health and safety commitments must all be documented in certain circumstances. This means employers must provide a written statement of some key rights and responsibilities from the outset of the employment relationship. By pulling these policies together in a single handbook, employers can demonstrate compliance and ensure employees are aware of their rights and responsibilities. In practice, most legal and HR experts, including ACAS and Gov.uk guidance, recommend having a handbook as it reduces legal risk and simplifies communication.
In short: while the handbook itself is not mandatory, several of the policies inside it are. A handbook is the simplest way to stay compliant.
Mandatory Policies Every UK Employer Must Include
Certain policies are required by law and should always be included in an employee handbook. These company policies reduce disputes, limit legal liability, and help ensure compliance with specific laws.
Health and Safety Policy
Employers with five or more staff must have a written health and safety policy. This should include:
A statement of intent setting out commitment to safety.
Details on the organisation of health and safety responsibilities within the company.
Specific arrangements and procedures to manage risks and emergencies. Even where there are fewer than five employees, employers still need to have a policy in place, though it can be communicated verbally.
Disciplinary and Grievance Procedures
Employers must set out disciplinary and grievance procedures that comply with the ACAS Code of Practice. Failure to follow the Code can lead to significant penalties. Employment tribunals have the power to increase compensation awards by up to 25% if an employer unreasonably fails to follow the Code, such as not giving employees the opportunity to appeal, not carrying out proper investigations, or not following a fair process when handling misconduct or grievances. A clear disciplinary policy and grievance policy within the handbook ensures employees understand the process in advance.
Equal Opportunities and Anti-Discrimination
The Equality Act 2010 requires employers to prevent discrimination across nine protected characteristics: age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex, and sexual orientation. A robust equal opportunities policy within the handbook shows commitment to fair treatment and helps defend against discrimination claims.
Sexual Harassment Prevention Policy (Introduced in 2024)
From October 26, 2024, UK employers became legally required to take reasonable steps to prevent sexual harassment under the Worker Protection (Amendment of Equality Act 2010) Act 2023. A compliant handbook should include:
A zero-tolerance statement on harassment.
Clear complaint and investigation procedures.
Training expectations for managers and staff.
Regular risk assessments and protections against third-party harassment. Failure to comply can result in increased tribunal compensation awards.
Additional Common Policies Strongly Recommended for Handbooks
Beyond the mandatory requirements, it is best practice to include other policies that reduce risk and improve workplace clarity. These policies help address common workplace issues and ensure clarity for both new employees and longer-serving staff. Examples include:
Data protection and privacy policies, particularly important under GDPR.
Flexible working policies, reflecting the new right to request from day one of employment and clarifying expected working hours.
Leave entitlements, including parental leave, bereavement leave, sick leave, neonatal care leave, and holiday policies.
Fire and rehire procedures, which are subject to a new statutory Code of Practice from 2025.
Remote working and monitoring policies, which are increasingly relevant in hybrid workplaces.
Optional extras such as a dress code, a code of conduct, and how performance reviews are managed can also be added to provide structure and transparency.
In short: you do not have to include all of these, but doing so reduces disputes and makes your workplace run more smoothly.
How Employment Level and Company Size Affect Requirements
Not all businesses face the same obligations. The requirements depend partly on size.
Company Size Checklist
Here’s a quick breakdown of what you need at different stages:
1–4 employees
Not required to have a written health and safety policy.
Still must comply with employment law.
An employee manual or handbook is strongly recommended to reduce disputes and give new hires a clear starting point, often supported by a short welcome letter.
5–19 employees
Written health and safety policy required.
Must comply with disciplinary, grievance, equal opportunities, and harassment prevention rules.
Handbook helps ensure consistency as team grows.
20+ employees
All of the above, plus additional consultation obligations (e.g., fire and rehire).
Tribunal risk is higher, so a full, well-maintained handbook is essential. Larger employers may also include extras like a mission statement, details of company offers, or policies on sickness absence and maternity leave, reflecting the wider range of staff needs.
Key Legislative Updates Employers Must Be Aware Of
Several significant changes to UK employment law have already come into effect or are scheduled to be implemented throughout 2025. Employee handbooks must be updated to reflect these new obligations:
Already Implemented Changes
Sexual Harassment Prevention Duties (October 26, 2024)
As already mentioned, under the Worker Protection (Amendment of Equality Act 2010) Act 2023, employers must now take "reasonable steps" to prevent sexual harassment. This represents a shift from reactive to proactive obligations, requiring comprehensive anti-harassment policies, clear complaint procedures, and regular training.
Enhanced Flexible Working Rights (April 2024)
Employees now have a day-one right to request flexible working, with entitlement to two requests per 12-month period. Employers must respond within two months and provide detailed explanations for any rejections.
Neonatal Care Leave and Pay (April 6, 2025)
Eligible parents can now take up to 12 weeks of neonatal leave (one week for each week their baby receives specialist neonatal care) in addition to existing statutory entitlements. This is a day-one right requiring no qualifying service period.
Fire and Rehire Code of Practice (January 2025)
The new statutory Code of Practice on dismissal and re-engagement strengthens consultation requirements and penalties. Non-compliance can result in compensation awards being increased by up to 25%.
Proposed Changes (Employment Rights Bill - Expected Autumn 2025)
The Employment Rights Bill, currently progressing through Parliament, includes several provisions that will require further handbook updates once enacted:
Enhanced Flexible Working Consultation
Employers will only be able to reject flexible working requests where it is "reasonable" to do so and must follow a more structured consultation process.
Bereavement Leave
A new right to unpaid bereavement leave from day one of employment is proposed, providing additional support for employees during difficult times.
Enhanced Paternity Leave
Proposed improvements include day-one rights and greater flexibility in how paternity leave can be taken.
Statutory Sick Pay Reforms
Plans to remove the three-day waiting period and lower earnings limit would extend SSP coverage to more workers.
Action Required
Immediate Updates Needed: Employers should ensure their handbooks reflect the sexual harassment prevention duties, enhanced flexible working rights, neonatal care leave, and fire and rehire procedures that are already in effect.
Future Preparation: Monitor the progress of the Employment Rights Bill and prepare for additional handbook updates once these provisions receive Royal Assent, likely in autumn 2025.
In short, if you have not updated your handbook since early 2024, you will need to revise it immediately to reflect these new rights and prepare for further changes throughout 2025.
Why Go Beyond the Minimum Requirements?
While meeting minimum legal requirements is essential, going further can protect organisations and strengthen workplace culture. Comprehensive handbooks:
Reduce the risk of tribunal claims.
Provide clarity for managers, reducing inconsistency in decision-making.
Help employees understand expectations, improving morale and reducing turnover.
Demonstrate a commitment to fairness and equality, supporting employer branding and recruitment.
Put simply: a basic handbook keeps you compliant, but a comprehensive one makes your business more resilient, attractive, and trusted.
Employee Handbook Examples
The policies you include in your employee handbook will vary depending on the size of your business. The table below highlights what is mandatory for different company sizes, along with examples of best practice policies that go beyond the minimum requirements:
| Company Size | Mandatory Policies / Requirements | Examples of Going Beyond |

Conclusion and Next Steps
The employee handbook is more than an HR formality; it is a living document that should evolve with changes in the law and in workplace culture. With new legislation on flexible working, neonatal leave, and sick pay now in place, employers must review and update their handbooks to remain compliant. A clear, comprehensive handbook not only helps meet legal requirements but also builds trust, consistency, and resilience in the workplace.
