Employment Rights Act 2025: What UK Employers Must Prepare for in 2026 and Beyond

As 2026 begins, UK employers are entering a period of sustained change in employment law. The Employment Rights Act 2025 which gained Royal Assent on 18 December 2025, is one of the biggest changes in the employment landscape in decades.

The Act is one of the main pillars of the Government Plan to Make Work Pay. The recommended objectives of it are to enhance wage security, lessen insecure work, and reestablish the balance between flexibility and protection at the workplace. Following a lengthy parliamentary process and revision, the new law brings in 28 new clauses that will have a direct implication on the dismissal practices, changes in contracts, industrial relations, and dispute resolution.

The implementation will be in phases, as some of the provisions are already in place and others will be implemented by 2026 and 2027. There is no longer a choice of early preparation. This is followed by a practical summary of the most effective reforms and their implications in a real sense for the employers.

Repeal of Minimum Service Levels During Strike Action

One of the earliest and most symbolic changes under the ERA 2025 was the repeal of the Strikes (Minimum Service Levels) Act 2023.

The employers of major industries like healthcare, fire, and transport companies do not have the legal authority to force employees to work during the strike. This is a definite revolution to the mandatory service requirements and a shift to collective bargaining as the most appropriate form of solving industrial conflicts.

Practically, this means that employers ought to check their approach to industrial relations and have an active and solid engagement with trade unions and employee representatives, documenting the process. The focus in the law has shifted towards voluntary resolution and away from enforcement.

ACAS Early Conciliation Extended to Twelve Weeks

Since 1 December 2025, ACAS Early Conciliation operates under a maximum twelve-week period, doubling the previous six-week timeframe. This is applicable to the notifications that are filed during or after that date.

The extension is a result of constant stress on the ACAS system and a significant increase in the early conciliation cases. This change offers both an opportunity and a risk to an employer. The conciliation window will be long enough to have more meaningful dialogue and internal investigation, as well as strategic decisions. It also prepares room to settle disputes when they are still at hand before it degenerates into tribunal cases, causing less cost, disruption, and image damage.

But now it is just to say that disputes can be kept alive. The employers ought to make sure that early conciliation is a dynamic process rather than a holding pattern. Early intervention of the law may be the difference between early dismissal and prolonged litigation.

Unfair Dismissal: A New Six-Month Qualifying Period

One of the most closely watched reforms relates to unfair dismissal rights.

The initial suggestion to bring protection against unfair dismissal on the first day was greatly opposed in the House of Lords. The last concession is that the qualifying period of two years is scaled down to six months instead of being completely eliminated. This is likely to come into force on 1 January 2027.

Although this still gives employers some slight initial room, there is considerably less room to make mistakes. The performance management, probation reviews, and early-stage conduct problems will have to be managed cautiously and consistently since the beginning of employment.

It is necessary to mention that a day-one protection against discrimination and automatic unfair dismissal are not altered.

Removal of the Compensatory Award Cap

Perhaps the most commercially significant reform under the ERA 2025 is the complete removal of the statutory cap on compensatory awards for unfair dismissal.

In the past, the maximum compensation was 52 weeks of gross pay or £118,223, whichever was lower. The ceiling shall be completely eliminated. With the force of law, employees will be in a position to make a claim compensated according to the full value of their financial loss.

This puts unfair dismissal cases in line with whistleblowing and discrimination claims and puts the senior employee with complicated remuneration packages at a high risk of exposure.

The Government has noted that such a reform will most probably be introduced together with the new qualifying period in January 2027. Review of the risk of dismissal, settlement plans, and insurance arrangements should be started by the employers much earlier.

Ending ‘Fire and Rehire’ Practices

The ERA 2025 introduces a decisive move to eliminate so-called fire and rehire practices.

The terminations related to some alterations in contract will be typically regarded as automatically unfair given that these alterations belong to a set of limited categories. These entail pay cuts, pensions reforms, working hours and leave benefits reforms and the introduction of terms where it can be varied unilaterally.

Most importantly, the employers will not be able to lay down the staff and hire agency employees or contractors to do the jobs that are substantially similar.

There is a limited exemption in the cases of abject financial distress, however, the standard of evidence is high. The employer will have to show that he or she is indeed in financial trouble, that there is a direct correlation between changes being proposed and the survival of the business, and that no alternatives can be implemented reasonably. These are provisions that are anticipated to be effective in October of 2026.

Zero-Hour and Low-Hour Contracts: Increased Predictability

Another issue that is covered in the Act is the issue of zero-hour and low-hour contracts.

Provided that the workers are able to prove a steady working pattern within a period of reference, which is expected to be about 12 weeks, they will have the right to request a contract where their actual hours will be reflected. Shifts will also be given reasonable notice by the employers, and seven days are bound to be the default norm.

Compensation can be triggered by short-notice cancellations or an increase in shifts. Although flexibility is not restricted, it should now be accompanied by predictability and fairness.

Strengthened Flexible Working Rights

Flexible working rights are also being expanded.

Employers under the ERA 2025 are not only expected to base their refusal on some of the allowed grounds in business but also must prove that the refusal is reasonable in the context. It will also introduce a duty to consult a request before refusing it, which will be further elaborated by secondary legislation.

These amendments will take effect in 2027 and will introduce a more formalized, documented procedure of requests of flexible working.

What Employers Should Be Doing Now

Although implementation is phased, the direction of travel is clear. The Employment Rights Act 2025 significantly raises the standard expected of employers across dismissal, contractual change, workforce planning, and dispute management.

Policies, manager training, and internal processes should be reviewed now, not when the changes take effect.

Final Thoughts

The Employment Rights Act 2025 is not a single reform but a sustained reshaping of UK employment law. Employers who engage early, plan carefully, and seek informed advice will be best placed to manage risk and maintain productive employment relationships in this evolving legal landscape.

Staying compliant is no longer about reacting to change. It is about anticipating it.
