When Will the ERB Become Law - A Roadmap for Employers

Written by Kirsten McKenzie. This article is up to date as of November 2025.

The UK Employment Rights Bill is shaping up to be one of the most significant changes to employment law in recent years. HR teams and business leaders know it is coming, but most are still unsure when the Employment Rights Bill will become law, when the new rights will come into effect, and what they should be doing right now to get ready.

This guide breaks it all down in simple terms with clear advice, practical steps and a roadmap that helps you plan ahead with confidence.

What the Employment Rights Bill is trying to achieve

The bill aims to modernise UK employment law, strengthen worker protections and create more consistency across family-friendly rights, dismissal rights and decision-making. If your HR team is already used to navigating the complexity of UK employment law, this bill will add another layer of work.

The good news is that with the right planning, the changes can be managed smoothly. Many of them even create opportunities to improve culture, reduce risk and build a stronger employee experience.

When will the Employment Rights Bill become law?

One of our frequently asked questions right now is: when will the Employment Rights Bill become law? i.e. how long do we have to get our ducks in a row?

The current expectation is as follows:

The bill is in the final stages of its passage through Parliament
Royal Assent is expected imminently.

Upon Royal Ascent, the government will start to create detailed regulations and guidance.
Most of the changes will be introduced throughout 2026 and 2027.

Like most employment legislation, implementation will not be a single moment. There will be staged rollouts, transitional periods and updates from ACAS. That is why many employers are now looking for an Employment Rights Bill roadmap to help them plan the next 18 to 24 months.

The Employment Rights Bill roadmap for employers

Below is a simple forward-looking timeline to help HR and leadership teams understand what is coming and when.

Phase 1: Preparation (late 2025 and early 2026)

This is your planning window. The most effective HR teams will use this time to:

Carry out a policy, contract and handbook audit.
Review recruitment practices.
Map out which of the ERB changes will impact their business the most.
Brief the leadership team on the changes and their obligations/expectations upon them.
Identify pinch points, create risk registers and identify mitigations.

Equip managers, ensuring they have the practical skills to meet new obligations around dismissal, absence management, harassment protections, etc.
Review payroll practices to ensure alignment to contracts, processes and policy, identifying any required changes to workflows to be compliant.
Plan your HR resources for 2026 and beyond.

The goal here is simple. You want to avoid the late 2025/early 2026 rush, where every employer is trying to fix the same problems at the same time.

Phase 2: Implementation

Core changes expected to go live in 2026 include:

Day one rights for certain family-friendly leave, including ordinary parental leave and paternity leave.
Statutory Sick Pay from day one and removal of the lower earnings limit in some cases.
Enhanced whistleblowing protections (including for sexual harassment disclosures).

Doubling the threshold for the protective award where there has been a failure to consult.
Firing and rehiring employees on worse terms and conditions expected to become an automatic unfair dismissal in most cases.
Requirement for employers to take all reasonable preventative steps to protect employees from sexual harassment.
Greater focus on diversity reporting, such as the gender pay gap and menopause action plans for larger employers.

Increased rights of Trade Unions to be recognised.

Core changes expected to go live in 2027 include:

Removal or reduction of the two-year qualifying period for unfair dismissal.
New requirements on collective redundancy consultation, including the need to consider the total number of redundancies across the whole organisation, not just individual workplaces.

Workers on zero-hour contracts are expected to get the right to guaranteed working hours, if they want them.

Each of these areas affects people, processes, documentation, training and manager capability.

For HR leaders already stretched thin, this could create real pressure if not well planned.

Phase 3: Embedding and long-term change (2027 and beyond)

Once the main rights are in place, HR teams will need to embed new behaviours, processes and expectations. This includes:

Training managers on dismissal handling and documentation
Reviewing absence and occupational health processes
Updating flexible working practices
Strengthening bullying, harassment and equality frameworks
Refreshing onboarding to reflect new rights
Tightening internal communication so employees understand their entitlements clearly

2027 is the year where culture, capability and consistency matter most. It is when strong HR teams will stand out.

What employers should do now?

Here is the practical part. This is what you can start today without waiting for the law to take effect.

1. Audit your HR policies, processes and contracts

Most businesses will discover gaps in:

Parental leave policies
Sickness and absence management
Dismissal procedures
Redundancy processes
Flexible working frameworks
Whistleblowing and harassment policies

A simple gap analysis now will save you time and cost next year.

2. Strengthen your dismissal, ER and performance processes

With potential changes to unfair dismissal rules, employers will need tighter documentation, better manager confidence and stronger HR support.

3. Prepare for day one rights

Day one entitlements will change expectations around onboarding, eligibility and absence. Make sure your HR systems and workflows can handle this.

4. Upskill your managers

Most Employment Rights Bill risks sit with line managers who are at the centre of compliance. Clear training and simple guidance will reduce risk more than any document.

5. Plan your HR capacity

If your HR team is already stretched, 2026 will be even harder. Interim support or project-based help can make the workload manageable.

Where employers often underestimate the workload

From our work with HR teams across the UK, the biggest surprises usually come from:

The time it takes to update every policy, process and template
The need for manager training, not just documentation
The volume of employee queries when new rights become day one rights
The impact on SMEs or standalone HR managers who are spinning multiple plates

This is why early planning matters. It reduces cost, risk and stress for everyone involved.
