Employment Rights Act 2025 — What Every UK Employer Needs to Know

The Employment Rights Act 2025 is the most significant expansion of workers’ rights in the UK since the Employment Relations Act 1999. It’s the legislative centrepiece of the government’s “Make Work Pay” agenda, and it arrives in stages between April 2026 and January 2027. The Act removes qualifying periods for key protections, creates new employer duties to prevent harassment, reforms Statutory Sick Pay, extends tribunal time limits, and establishes a new enforcement body — the Fair Work Agency.

For UK employers, this isn’t a distant regulatory change you can watch unfold on the news. It’s immediate, practical, and affects nearly every aspect of how you hire, manage, and dismiss staff. Most SMEs have not yet updated their contracts or policies to reflect the changes. Many are operating on assumptions about qualifying periods and harassment liability that are about to become outdated. The financial risk of getting it wrong has roughly doubled.

This guide walks you through what the Act is, what it actually changes, who it applies to, and why it matters to your business right now.

Why This Matters

For decades, UK employment law operated on a broad principle: newer employees had fewer rights than longer-serving ones. The most visible symbol of this principle was the two-year qualifying period for unfair dismissal protection. You could dismiss someone in their first year with minimal procedural fairness; after two years, you had to follow due process.

That principle is disappearing. The Employment Rights Act flattens these protections — removing or dramatically shortening qualifying periods, creating new duties for employers to prevent harassment, and extending the window during which employees can bring tribunal claims.

The practical impact is substantial. Day-one employment rights mean you need fair processes from hire date one. The “all reasonable steps” harassment duty means you can’t just react to complaints; you have to actively prevent them. The extended tribunal time limits (from three to six months) mean exposure for employment disputes lasts twice as long. And the Fair Work Agency — a new enforcement body with proactive investigation powers — means compliance isn’t just about defending claims when they arrive; it’s about surviving inspections.

For hospitality, retail, care, and gig economy businesses, the impact is sharpest. These sectors rely heavily on zero-hours contracts, have the highest staff turnover, and employ the most lower-paid workers. Day-one Statutory Sick Pay, for example, removes an earnings threshold that previously excluded many hospitality workers from SSP. For businesses built around low-margin, high-turnover models, this changes the cost calculation directly.

But the impact isn’t limited to high-turnover sectors. Every UK employer is in scope. A business with one employee faces the same fundamental obligations as a business with 10,000.

What the Act Changes — The Four Phases

The Act doesn’t arrive all at once. It unfolds in four phases, each adding new obligations in quick succession.

Phase 1 — April 2026.

• Unfair dismissal qualifying period drops from two years to six months (subject to a statutory probation period framework, details still pending).
• Statutory Sick Pay applies from day one with no three-day waiting period and no lower earnings limit. This means even part-time, lower-paid workers get SSP from day one of any sickness absence.
• Paternity leave becomes available from day one and can be taken flexibly within the first year.
• Protective awards for failure to consult on collective redundancies double.
• Fair Work Agency formally launches with proactive investigation powers.

Phase 2 — October 2026.

• “All reasonable steps” employer harassment prevention duty comes into force. This requires documented policies, staff training, risk assessments, and active prevention measures — not just reactive complaint handling.
• Tribunal time limits extend from three to six months for most claims. Employees now have twice as long to bring a claim.
• Trade union notification duties for employers change.

Phase 3 — January 2027.

• Unfair dismissal qualifying period drops to six months (the statutory probation framework provides the lighter-touch dismissal process during early employment).
• Zero-hours contract guaranteed-hours provisions come into force. Workers will have the right to a contract reflecting their regular hours after a qualifying period.

Phase 4 — April 2027.

• Statutory probation period secondary legislation expected. This will define exactly how the lighter-touch dismissal process works during probation.

The cascade effect is the critical pattern. An SME that updates for April 2026 is hit again in October, then again in January. This isn’t a single compliance event; it’s rolling regulatory change.

Who’s in Scope

All UK employers. There is no small-business exemption for the core provisions. A business with one employee is subject to the same fundamental employment rights as a business with 10,000.

Some specific provisions have practical thresholds. Collective redundancy consultation applies to businesses making 20 or more redundancies in a 90-day period. Trade union consultation applies where unions are formally recognised. But the headline changes — day-one rights, SSP reform, harassment duties, tribunal extensions — apply universally.

Sectors most affected: Hospitality, retail, care, and gig economy businesses face the sharpest impact due to high use of zero-hours contracts, high staff turnover, and customer-facing roles where harassment duties are most relevant. Professional services and office-based SMEs face a softer practical impact but still need contract and policy updates.

The Enforcement Picture

Enforcement of employment rights happens in two main channels: the Fair Work Agency (new, proactive) and employment tribunals (existing, complaint-driven).

Fair Work Agency. Launched April 7, 2026, the FWA consolidates several existing enforcement bodies. It has investigation powers for employment rights, national minimum wage, holiday pay, and Statutory Sick Pay. The key shift: the FWA can take proactive enforcement action. It doesn’t need to wait for a complaint. It can inspect, audit, and investigate based on identified risks. For SMEs accustomed to employment law being enforced only through individual tribunal claims, this is a significant change.

Employment tribunals. The primary mechanism for most employment rights enforcement. Key changes from the Act:

• Tribunal time limit extends from three months to six months (from October 2026). This doubles the window during which employees can bring claims.
• Protective awards for failure to consult on collective redundancies are doubled.
• The unfair dismissal qualifying period changes (dropping to six months) and introduces a statutory probation framework that employers can rely on.

Financial exposure. Unfair dismissal compensation is capped at £115,115 (2025/26), but this is regularly uprated annually. Discrimination claims (which harassment duty changes relate to) are uncapped. A successful harassment claim can result in compensation for injury to feelings (Vento bands: lower £1,100–£11,200, middle £11,200–£33,700, upper £33,700–£56,200 as of April 2025) plus lost earnings. Employer liability for third-party harassment is particularly costly because the “all reasonable steps” defence is hard to establish — you must demonstrate documented policies, training, risk assessment, and monitoring.

Six Common Misconceptions

Many employers misunderstand what the Act actually changes. Here are six myths that have spread widely.

“Day-one rights means we can’t use probation periods.” The Act introduces a statutory probation period framework — likely 6–9 months (secondary legislation pending). During probation, employers can dismiss using a lighter-touch “fair and transparent” process. Probation isn’t abolished; it’s formalised with legal guardrails. But the details matter, and many SMEs are making assumptions about what probation will look like before the regulations are published.

“We’re too small for the Fair Work Agency to bother with.” The Fair Work Agency consolidates enforcement that already targeted small businesses — national minimum wage inspections, holiday pay enforcement, SSP compliance. Small employers are already subject to these inspections; the FWA just makes enforcement more coordinated and proactive.

“Harassment is a big-company problem.” Smaller workplaces are actually higher-risk for harassment because there’s less structural separation between individuals, fewer formal reporting channels, and often no dedicated HR function. The “all reasonable steps” duty applies regardless of size.

“We updated contracts in 2020, so we’re fine.” The 2026 changes alter the fundamental employment relationship. Contracts and policies written before April need specific updates to reflect day-one rights, SSP changes, the probation framework, and harassment duties. A 2020 contract is not a 2026-compliant contract.

“Fair intent is the same as legal compliance.” Fair treatment is important, but it’s not the same as legal compliance. The “all reasonable steps” harassment standard specifically requires documented policies, training, risk assessments, and monitoring. The Fair Work Agency can request evidence. “We treat everyone well” is not evidence.

“The qualifying period for unfair dismissal is still two years.” From January 2027, it drops to six months (subject to statutory probation provisions). This means managers can no longer rely on a two-year buffer to manage underperformers informally. Dismissal has to be fair from day six of employment.

What You Need to Do

1. Audit your employment contracts. Check every contract against the Phase 1 changes (April 2026). Do they reflect day-one rights? Is the SSP clause current? Is the probation clause aligned with the statutory framework? Flag contracts that need updating and prioritise by employee start date.

2. Update your harassment policy. Move from reactive (“if you experience harassment, report it”) to proactive (“here’s how we prevent it”). The “all reasonable steps” standard requires: a clear policy, staff training, risk assessment for harassment types relevant to your workplace, reporting mechanisms, and monitoring. Document everything.

3. Train your managers. Day-one rights and shorter qualifying periods mean fair process from hire date one. Managers need to understand: fair reasons for dismissal, the importance of documented performance management, how to conduct fair capability and disciplinary processes, and the harassment prevention duty.

4. Review zero-hours arrangements. If you use zero-hours or variable-hours contracts, assess which workers would qualify for guaranteed-hours contracts under the new provisions (January 2027). Model the financial impact. Plan for the transition.

5. Update your sickness absence process. SSP from day one with no lower earnings limit changes the calculation for every employee absence. Update payroll systems and absence management procedures by April 2026.

6. Prepare for longer tribunal exposure. The six-month time limit (from October 2026) means claims can arrive much later. Ensure you retain documentation (disciplinary records, performance notes, meeting minutes) for at least 12 months after any employment event.

7. Understand the Fair Work Agency. Monitor FWA publications for enforcement priorities and inspection criteria. Being aware of what they’re looking for is the first step in being prepared.

8. Budget for ongoing compliance. This is not a one-off update. Secondary legislation is still being published, the statutory probation framework details are pending, and enforcement patterns will emerge throughout 2026–2027. Budget for at least an annual compliance review.

How to Check It Worked

After you’ve made these updates, verify:

• Every employment contract has been reviewed and updated for Phase 1 changes (or flagged for solicitor review if non-standard).
• Your harassment policy covers prevention, not just complaint handling — with documented training records and risk assessments.
• Your payroll systems calculate SSP from day one for all employees, regardless of earnings.
• Your managers understand that new employees have rights from day one and can articulate fair dismissal processes.
• You have a documented record of which employees are on zero-hours contracts and which would be affected by guaranteed-hours provisions.
• Your document retention policy requires keeping employment records for at least 12 months after any employment event.

What’s Next

The statutory probation secondary legislation (expected April 2027) will define the exact procedure for lighter-touch dismissals during probation. Until then, assume probation is permitted within a statutory framework and plan for a dismissal process that’s fair, documented, and transparent.

The Fair Work Agency enforcement patterns will emerge throughout 2026. Monitor FWA guidance, industry reports, and inspection findings to understand which sectors and practices are drawing regulatory scrutiny.

And the tribunal time limit extension (October 2026) means exposure for employment events in Phase 1 extends into Phase 2 and beyond. This is why documentation discipline (keeping records, recording decisions, documenting conversations) becomes more important, not less.
