The 2026 Employment Law Overhaul: What UK Employers Must Know Now

Key Takeaways

• Paternity leave and unpaid parental leave become day-one rights from 6 April 2026, removing previous service requirements entirely.
• Statutory Sick Pay rises to £123.25 per week from 6 April 2026, payable from day one of illness with the lower earnings limit removed.
• Fire and rehire protections, now confirmed as automatic unfair dismissal in most cases, take effect from 1 January 2027, not October 2026 as originally planned.
• The protective award for collective redundancy consultation failures doubles to 180 days' pay from April 2026.
• A new Fair Work Agency launches in April 2026 to enforce statutory rights including holiday pay and SSP.

Introduction

If you run a business in the United Kingdom, 2026 is not a year to watch from the sidelines. The Employment Rights Act 2025, which received Royal Assent on 18 December 2025, represents the most comprehensive overhaul of workplace rights in a generation. Its reforms are rolling out in phases across 2026 and into 2027, and the window for preparation is narrowing fast.

The changes span family leave, sick pay, redundancy, fire and rehire, harassment protections, and enforcement. Some are already in force. Others arrive in April. More follow in October. And a final wave lands in January 2027. Each phase carries its own compliance obligations, and missing a deadline carries real financial and legal risk.

This guide maps the full timeline, corrects a widely circulated misconception about when fire and rehire protections actually take effect, and sets out the practical steps employers need to take now.

The Legislative Foundation: Employment Rights Act 2025

The Employment Rights Act 2025 is the statutory vehicle for almost every major change discussed in this article. It received Royal Assent on 18 December 2025, but Royal Assent alone does not bring provisions into force. Each reform requires a commencement order, which is why the changes are phased across multiple dates rather than taking effect simultaneously.

Employers should treat the phased timetable as a compliance calendar, not a distant concern. Some obligations have already commenced. Others require policy updates, contract reviews, and staff training before their effective dates arrive.

April 2026: The First Major Wave

Day-One Rights for Paternity Leave and Unpaid Parental Leave

From 6 April 2026, both paternity leave and unpaid parental leave become day-one entitlements. Previously, employees needed 26 weeks of continuous employment to qualify for paternity leave, and one full year of service for unpaid parental leave. Both thresholds are removed entirely.

One important distinction applies to pay. While the right to take paternity leave is now available from day one, the qualifying period for Statutory Paternity Pay remains at 26 weeks of continuous employment. An employee who starts a new role and takes paternity leave immediately can take the time off, but will not receive statutory pay unless they have at least 26 weeks of service by the qualifying week.

Employees have been able to give advance notice of their intention to take leave since 18 February 2026, with the notice period for paternity leave temporarily reduced from 15 weeks to 28 days.

Bereaved Partners: Extended Paternity Leave

From 6 April 2026, bereaved fathers and partners will be entitled to take up to 52 weeks of unpaid paternity leave if the mother or primary adopter dies within the first year of the child's life. This applies to children born on or after 6 April 2026, or where the mother or primary adopter dies on or after that date.

Statutory Sick Pay Reform

Two significant changes to Statutory Sick Pay (SSP) take effect from 6 April 2026:

• The three-day waiting period is abolished. SSP becomes payable from day one of illness.
• The lower earnings limit is removed. Previously, employees needed to earn at least £125 per week to qualify. That threshold disappears entirely.

The flat rate of SSP rises from £118.75 to £123.25 per week. Employees who earn below the previous lower earnings limit will receive SSP at 80% of their normal weekly earnings, or the flat rate of £123.25, whichever is lower.

Statutory Family Pay Rates

From 6 April 2026, statutory maternity pay, paternity pay, shared parental pay, adoption pay, and parental bereavement pay all rise from £187.18 to £194.32 per week.

Collective Redundancy: Protective Award Doubles

Employers who fail to comply with collective consultation obligations now face significantly higher exposure. From April 2026, the maximum protective award for failing to collectively consult doubles from 90 days' pay to 180 days' pay per affected employee.

Where an employer also fails to comply with the statutory ACAS Code of Practice on Dismissal and Re-Engagement, the protective award can be increased by a further 25%, bringing the potential maximum to 225 days' gross pay per affected employee.

Whistleblowing: Sexual Harassment as a Protected Disclosure

From April 2026, sexual harassment becomes a qualifying disclosure under the whistleblowing regime. Employees who raise concerns about sexual harassment will gain protection from detriment and unfair dismissal as whistleblowers.

Fair Work Agency Launches

A new Fair Work Agency is established in April 2026. It will bring together existing enforcement bodies and take on responsibility for enforcing rights including holiday pay, SSP, and national minimum wage compliance. Employers should expect a more active enforcement environment, including the possibility of proactive audits.

October 2026: The Second Wave

Extended Harassment Duties

From October 2026, the employer duty to prevent sexual harassment is strengthened. Employers will be required to take "all reasonable steps" to prevent sexual harassment, an elevated standard compared to the previous "reasonable steps" obligation. Employer liability for third-party harassment is also reintroduced.

Employment Tribunal Time Limits Extended

The time limit for employees to bring most employment tribunal claims doubles from three months to six months. This significantly extends the window during which employers may face claims, and reinforces the importance of thorough documentation at every stage of a disciplinary or dismissal process.

Trade Union and Tipping Changes

October 2026 also brings a new duty for employers to inform workers of their right to join a trade union, updated trade union access rules, and tipping consultation requirements.

January 2027: Fire and Rehire Protections Take Effect

The Critical Correction

Multiple sources initially indicated that fire and rehire protections would take effect in October 2026. That date has been revised. The Government confirmed in February 2026 that these provisions will now come into force on 1 January 2027, subject to commencement regulations. The GOV.UK factsheet published in February 2026 confirms this date explicitly.

Employers who have been planning for an October 2026 deadline need to update their timelines accordingly.

What the New Rules Mean

Under the Employment Rights Act 2025, dismissing an employee because they refuse to accept a "restricted variation" to their contract will constitute automatic unfair dismissal in most cases. Restricted variations include:

• Reductions to pay
• Changes to total working hours
• Reductions to leave entitlement
• Changes to pension terms
• Specified shift pattern changes

It will also be automatically unfair to dismiss an employee in order to replace them with someone else, including agency workers, on amended terms relating to pay, pension, hours, or holiday entitlement.

A narrow exception exists where the employer can demonstrate genuine financial difficulties that were affecting, or were likely to affect, the business. This is a high threshold, not a general business case justification.

Until 1 January 2027, the existing legal framework continues to apply, including the statutory ACAS Code of Practice on Dismissal and Re-Engagement. However, employers considering restructuring exercises now should assess their plans against the incoming framework, as decisions taken today may be scrutinised against the new standard once it is in force.

Unfair Dismissal Qualifying Period Reduces

Also from January 2027, the qualifying period for ordinary unfair dismissal claims reduces from two years to six months. From that date, the cap on the compensatory award for unfair dismissal is also removed entirely.

Practical Steps for Employers

Given the scale and pace of these changes, a structured compliance approach is essential:

1. Review and update contracts and policies before 6 April 2026. SSP waiting day provisions, parental leave policies, and redundancy procedures all require revision.
2. Train HR teams and line managers on the new day-one rights, the revised SSP rules, and the incoming fire and rehire framework.
3. Audit collective redundancy processes now. With the protective award doubling, the cost of non-compliance has increased materially.
4. Prepare for Fair Work Agency scrutiny. Review holiday pay calculations, SSP administration, and minimum wage compliance before the agency becomes operational.
5. Reassess any planned restructuring exercises in light of the January 2027 fire and rehire provisions. If contractual changes are necessary, pursue genuine agreement rather than dismissal and re-engagement wherever possible.
6. Update tribunal response procedures to account for the extended six-month claims window from October 2026.
7. Monitor the ongoing consultation on restricted variations, which closes on 1 April 2026, for further regulatory detail on shift pattern changes.

Act Now: The Compliance Window Is Closing

The Employment Rights Act 2025 is not a future concern. Several of its provisions are already in force, and the April 2026 changes are imminent. Employers who delay risk financial exposure, tribunal claims, and reputational damage.

Review your employment contracts, update your policies, and seek specialist legal advice tailored to your workforce and sector. The cost of preparation is a fraction of the cost of non-compliance.
