Introduction
The Employment Rights Act 2025 represents the most significant change to UK employment law in years, and while it isn't an insurance statute, it materially reshapes the employment tribunal risk that employment practices liability cover exists to address. This guide explains what the Act actually changes, when each change takes effect, and what it means for the insurance side of running a UK business, complementing our broader guides on management liability insurance and employers' liability insurance, which covers a different, non-employment-tribunal risk relating to workplace injury and illness.
Key Terms Explained
- Employment Rights Act 2025
- UK legislation that received Royal Assent on 18 December 2025, introducing a wide range of changes to employment law, with provisions being implemented in stages through 2026 and into 2027.
- Qualifying Period
- The minimum length of continuous employment a worker needs before they can bring an ordinary unfair dismissal claim, currently two years and reducing to six months from 1 January 2027.
- Employment Practices Liability (EPL)
- A form of cover, usually included within a management liability or business insurance package, that covers the cost of defending and settling employment-related claims such as unfair dismissal, discrimination and harassment.
- Third-Party Harassment
- Harassment of an employee by someone who isn't a fellow employee, such as a customer, client, contractor or supplier, for which employers are gaining extended liability under the Act.
- Employment Tribunal
- The specialist tribunal that hears employment-related disputes in the UK, including unfair dismissal, discrimination and harassment claims brought by employees or workers against employers.
Why This Matters
For any UK business with employees, the Employment Rights Act 2025 changes the practical likelihood and nature of employment tribunal risk, particularly by significantly shortening the qualifying period for unfair dismissal claims and extending liability for harassment by people outside the organisation. This matters for insurance because employment practices liability cover, and the wider management liability policies it usually sits within, are priced and structured around exactly this kind of risk. Understanding the changes now, well ahead of the January 2027 unfair dismissal reforms, gives employers time to review both their HR practices and their insurance cover in a considered way rather than reactively.
Overview of the Employment Rights Act 2025
The Employment Rights Act 2025 received Royal Assent on 18 December 2025, following an extended passage through Parliament, and is described by the government as delivering on a wide-ranging set of manifesto commitments to strengthen employment rights. Rather than taking effect all at once, the Act's provisions are being implemented in stages, with some changes beginning in 2026 and others, including the headline unfair dismissal reforms, not taking effect until January 2027. This phased approach gives employers a genuine window to prepare, but also means the practical risk landscape will keep shifting through 2026 and 2027 as further provisions come into force.
Unfair Dismissal: What Actually Changed
The headline reform is a substantial reduction in the qualifying period for ordinary unfair dismissal claims, from the current two years of continuous employment down to just six months, taking effect from 1 January 2027. This means employees will be able to bring an ordinary unfair dismissal claim considerably earlier in their employment than under the current rules, expanding the pool of staff who could potentially bring this type of claim against any given employer. Alongside the shorter qualifying period, the cap on compensation for unfair dismissal claims falling within this newly expanded group is being removed, which could mean higher potential awards for successful claims relating to shorter-tenure employees than has previously been the case.
Separately, the time limit for bringing most employment tribunal claims, including unfair dismissal, is being extended from three months to six months, giving employees considerably longer after the event to decide whether to pursue a claim.
Why Day-One Rights Were Dropped
It's worth being clear about what didn't happen, since this has caused some confusion. The government's original manifesto commitment was to introduce day-one protection from unfair dismissal, effectively removing the qualifying period altogether. This was dropped shortly before the Act received Royal Assent, following extensive consultation and concern from business groups about the practical impact of removing any qualifying period at all. The six-month qualifying period that will apply from January 2027 is a significant reduction from the current two years, but it's a materially different, less far-reaching change than the day-one protection originally proposed.
Third-Party Harassment Liability
From October 2026, employers become liable for the harassment of their staff by third parties, such as customers, clients, contractors or members of the public, extending employer responsibility beyond harassment between colleagues. This is a genuinely significant change for sectors with high levels of public-facing contact, such as hospitality, retail and healthcare, where employees have historically had limited recourse against their employer for harassment by a customer or member of the public, even where the employer was aware of a pattern of behaviour and failed to act.
Other Significant Changes in the Act
Beyond unfair dismissal and third-party harassment, the Act introduces a wide range of further changes being implemented across 2026, including strengthened rights around statutory sick pay from the first day of illness, changes to fire-and-rehire practices, new rights relating to flexible working requests, and enhanced protections around whistleblowing. Employers should treat this as a broad, ongoing programme of change rather than a single event, and take specialist employment law advice on the full scope of provisions relevant to their specific business and workforce.
Fire and Rehire: The New "Triple Lock"
The Act introduces significant new restrictions on so-called "fire and rehire" practices, where an employer dismisses an employee and re-engages them on less favourable terms after they refuse to agree to a contractual change. Due to be implemented from January 2027 alongside the main unfair dismissal reforms, the Act creates what has been described as a "triple lock": two new categories of automatic unfair dismissal, subject to a narrow severe financial distress defence for the employer, plus a new form of ordinary unfair dismissal carrying special fairness considerations for cases involving what the Act terms a "restricted variation" of contract terms, covering matters such as pay, hours of work and holiday entitlement.
For employers, this significantly narrows the circumstances in which dismissing and re-engaging staff on varied terms can be treated as fair, and materially increases the risk profile of restructuring exercises that rely on this approach. Employment practices liability cover becomes particularly relevant here, given the potential for multiple, related unfair dismissal claims arising from a single restructuring decision.
Zero Hours Contracts and Guaranteed Hours
Separate provisions relating to zero and low hours contracts are due to be introduced at some stage in 2027, requiring employers to offer guaranteed hours contracts to workers who regularly work consistent hours over a reference period, expected to be twelve weeks. This includes a duty to offer guaranteed hours reflecting a worker's typical pattern, a requirement to give reasonable notice of shifts, and a duty to pay compensation where a shift is cancelled, moved or curtailed at short notice. Employers relying heavily on zero or low hours arrangements, particularly in retail, hospitality and care, should treat this as a significant future compliance requirement even though the detailed implementation timetable is still being finalised.
Whistleblowing and Sexual Harassment Disclosures
From 6 April 2026, sexual harassment became a "qualifying disclosure" under UK whistleblowing law, meaning an employee who raises a genuine concern about sexual harassment in the workplace gains the same statutory protection from detriment and unfair dismissal as other protected whistleblowing disclosures. This sits alongside, and reinforces, the Act's other harassment-related provisions, and reflects a wider trend of strengthening protections for employees who raise workplace misconduct concerns. Employers should ensure whistleblowing policies and manager training explicitly reflect this change.
Day-One Paternity, Parental and Bereavement Leave
From 6 April 2026, the Act introduced day-one rights to paternity leave and unpaid parental leave, removing the previous qualifying service requirement for these specific types of leave, though employees still need 26 weeks of service to qualify for statutory paternity pay itself, mirroring the equivalent maternity pay rule. Separately, the Act creates a new day-one right to unpaid bereavement leave, adapting and widening the existing parental bereavement leave regime to cover the death of a broader category of relatives, and extending the right to at least one week of unpaid leave to employees and partners experiencing a pregnancy loss before 24 weeks. The statutory bereavement leave provisions are expected to take effect in 2027.
Collective Redundancy Consultation Changes
The Act also changes the trigger for collective consultation duties in redundancy situations. From 6 April 2026, the duty to collectively consult is triggered where an employer proposes 20 or more redundancies at a single establishment within 90 days, as before, but also where a specified threshold of redundancies is proposed across more than one establishment within the same 90-day period, addressing a previous gap where employers with job losses spread across multiple sites could sometimes avoid the collective consultation duty entirely. At the same time, the maximum protective award for failing to properly consult was increased to 180 days' pay per affected employee, a significant increase in the potential financial exposure for employers who don't follow the correct collective consultation process during a redundancy exercise.
Key Changes and Implementation Dates
| Change | Effective From | Relevance to Insurance |
|---|---|---|
| Royal Assent | 18 December 2025 | Act becomes law; provisions phased in afterward |
| Third-party harassment liability | October 2026 | Expands the scope of potential harassment claims against employers |
| Unfair dismissal qualifying period reduced to six months | 1 January 2027 | Significantly expands the pool of employees who can claim |
| Compensation cap removed for affected claims | 1 January 2027 | Potentially higher claim values for shorter-tenure dismissals |
| Tribunal claim time limit extended to six months | Phased from 2026 | Longer window in which claims can be brought |
This table summarises the headline provisions most relevant to employer insurance risk and isn't a complete list of every change in the Act. Employers should confirm the full, current implementation timetable directly against official government and specialist employment law sources, since further detail and secondary legislation is expected to be published as each stage approaches.
What Employment Practices Liability Insurance Covers
Employment practices liability, typically included within a management liability policy or a broader business insurance package, generally covers the cost of defending employment tribunal claims such as unfair dismissal, discrimination, harassment and wrongful dismissal, along with any resulting settlement or award, subject to the specific policy's terms and limits. This cover exists specifically because defending even an unsuccessful tribunal claim can be costly and time-consuming, and because awards for successful claims, particularly discrimination claims which have historically been uncapped, can be substantial. Our guide on management liability insurance covers this type of cover, and the other components commonly bundled alongside it, in full detail.
How the Act Affects Existing Cover
The Employment Rights Act 2025 doesn't automatically change the terms of an existing employment practices liability policy, but it does change the underlying risk the policy is designed to respond to. As the qualifying period reduction and third-party harassment liability take effect, employers may see a genuine increase in the range of circumstances that could give rise to a covered claim. It's sensible to review your policy's specific definitions, exclusions and indemnity limits against this evolving risk picture, rather than assuming cover arranged some years ago automatically reflects the post-reform landscape.
Management Liability Insurance More Broadly
Employment practices liability is usually just one component of a wider management liability policy, which can also include directors' and officers' liability, covering personal claims against company directors and senior managers, and sometimes company liability and health and safety offence cover. Our guide on directors and officers insurance covers this related but distinct area, which can become relevant where an employment claim also names a director or senior manager personally, as sometimes happens in more serious cases.
Practical Steps for Employers
Ahead of each staged implementation date, employers should review current employment contracts, disciplinary and grievance procedures, and anti-harassment policies against the incoming changes, seek specialist employment law advice tailored to their specific workforce and sector, and check their existing employment practices liability or management liability cover reflects their likely future risk profile rather than the risk landscape as it stood before the Act. Businesses in customer-facing sectors should pay particular attention to the October 2026 third-party harassment provisions given the practical exposure this creates.
Considerations for Small and Medium Employers
The Employment Rights Act 2025 generally applies across employers of all sizes, and smaller businesses without dedicated in-house HR or legal resource may find the shortened unfair dismissal qualifying period and extended time limits particularly significant, since they often have less capacity to manage the process and cost of defending a claim internally. This makes reviewing employment practices liability cover, and the practical value of clear, well-documented HR processes, especially worthwhile for smaller employers who may currently be relying on informal or ad hoc management of employment risk.
Reviewing HR Policies and Contracts
Beyond insurance, the most effective response to the Act is often a practical one: reviewing and updating employment contracts, probationary period processes, disciplinary and grievance procedures, and anti-harassment policies so they reflect the incoming legal changes. Well-documented, consistently applied HR processes reduce the likelihood of a claim succeeding in the first place, and also tend to support a more straightforward, lower-cost defence where a claim is brought regardless of outcome, which is relevant both to the business directly and to how an insurer may view the risk over time.
What Happens If a Claim Is Brought
Where an employee brings an employment tribunal claim, an employer with employment practices liability cover should notify their insurer promptly, in line with the policy's specific notification requirements, since late notification can in some cases affect cover. The insurer will typically work with the employer, often through a panel of specialist employment solicitors, to defend the claim, and will cover defence costs and any settlement or award within the policy's terms and limits. Acting quickly and keeping clear records from the outset of any dispute puts both the employer and their insurer in a stronger position to manage the claim effectively.
Common Mistakes to Avoid
- Assuming the Act introduced day-one unfair dismissal rights, when the final version uses a six-month qualifying period instead.
- Waiting until January 2027 to review HR policies and insurance cover, rather than preparing ahead of each staged implementation date.
- Overlooking the October 2026 third-party harassment liability change if your business is customer-facing.
- Assuming existing employment practices liability cover automatically reflects the post-reform risk landscape without reviewing it.
- Failing to notify your insurer promptly when an employment tribunal claim is brought.
Common Myths
- Myth: Employees can now claim unfair dismissal from day one. The final Act reduces the qualifying period to six months rather than removing it entirely.
- Myth: The Act creates a new form of compulsory insurance. It doesn't; it changes the underlying employment risk landscape that existing employment practices liability cover addresses.
- Myth: Only large employers need to worry about the Act. It generally applies across employers of all sizes.
- Myth: All the changes take effect immediately. Provisions are being phased in through 2026 and into 2027 rather than all at once.
Real-World Examples
Example: Reviewing Probationary Periods
Ahead of the January 2027 qualifying period change, a small retail employer reviewed its probationary period and early-employment disciplinary process with specialist HR advice, aiming to ensure decisions taken during the first six months of employment were well documented and defensible.
Example: Customer-Facing Harassment Policy
A hospitality business updated its staff training and complaints procedure ahead of the October 2026 third-party harassment provisions, specifically addressing how staff should report and how management should respond to harassment by customers, rather than relying on its existing colleague-to-colleague harassment policy alone.
Example: Checking Employment Practices Liability Limits
A medium-sized employer reviewed its management liability policy's employment practices liability indemnity limit in light of the compensation cap removal for certain unfair dismissal claims from January 2027, and discussed with its broker whether the existing limit remained appropriate for its size and sector.

Conclusion
The Employment Rights Act 2025 doesn't create a new compulsory insurance requirement, but it substantially reshapes the employment tribunal risk that employment practices liability cover exists to address, particularly through the reduced unfair dismissal qualifying period from January 2027 and the new third-party harassment liability from October 2026. Employers have a genuine window to prepare: reviewing HR policies and contracts, taking specialist legal advice, and checking existing management liability or employment practices liability cover against this evolving risk landscape now, rather than waiting until each change takes effect.
