This article reflects Unfair Dismissal and the Employment Rights Act 2025 as enacted, including the House of Lords amendment reducing the qualifying period to six months (not day one) and the removal of the compensation cap.
From 1 January 2027, the Employment Rights Act 2025 (ERA 2025) will reduce the qualifying period for unfair dismissal from two years to six months. This is a fundamental shift in the UK employment law. Employers must urgently review probation periods, update onboarding processes and strengthen disciplinary procedures to reduce the considerable financial risks of non-compliance, including the simultaneous removal of the statutory cap on unfair dismissal compensation.
The UK legal framework for managing the workplace is undergoing a fundamental transformation. The ERA 2025 received Royal Assent in December 2025, with implementation planned on a phased basis for 2026 and 2027. The most significant shift for most employers is the reduction in the unfair dismissal qualifying period, effective 1 January 2027. Crucially, any employee hired before July 2026 who remains employed at that date will immediately acquire these enhanced statutory rights.
For many years, businesses have relied heavily on probationary periods as a low-risk way to dismiss unsuccessful hires. Managers could assess performance informally and terminate employment with minimal legal exposure in the first 24 months. The ERA 2025 significantly reduces this window. Continuing to rely on informal, undocumented approaches will soon transform into a major financial liability, especially given the removal of the compensation cap. Employers must now prioritise robust HR compliance to protect their commercial interests.
This article details the impending changes in UK employment law, explains the reduced value of standard probation clauses and outlines the preventive steps organisations must take today. To steer this transition safely, businesses must perform comprehensive health checks of employment law well before the 2027 deadline.
What Does the Employment Rights Act 2025 Mean for Unfair Dismissal?
The ERA 2025 reduces the qualifying period for unfair dismissal claims from two years to six months, effective from 1 January 2027. This falls short of the original ‘day one’ proposal, which was amended following defeats in the House of Lords, but still represents the most significant change to unfair dismissal law since the qualifying period was extended to two years in April 2012.
Important: The ERA 2025 does not grant day-one unfair dismissal protection. Employees will qualify for protection after 6 months of continuous service, not from their first day of employment.
When the new qualifying period takes effect on 1 January 2027, its reach is immediate and broad. Employees who already have six months’ service on that date will be protected from that day. In practice, this means that any employee currently in post and any new hires made up to the end of June 2026 will be covered immediately when the legislation comes into effect. Only staff hired from July 2026 onwards will need to have served for 6 months before the new protections apply to them.
The legal sector forecasts indicate that employment tribunal claims will rise sharply as the qualifying period shortens. Without the two-year barrier that prevents most claims, dismissed employees will find it significantly easier to challenge the fairness of their termination. Employers bear the burden of proving that dismissals within the first six months of employment follow fair, lawful procedures.
The removal of the Compensation Cap: A Critical Change.
Alongside the reduction in the qualifying period, ERA 2025 launches a second significant change that has received less attention but will have similarly profound consequences for employers: the complete abolition of the statutory cap on unfair dismissal compensation.
Under current law, compensation for unfair dismissal is subject to a statutory ceiling (currently the lower of £118,223 or 52 weeks’ gross pay). From 1 January 2027, both caps will be removed. Employment tribunals will be able to award uncapped compensation based on actual and future losses, which may extend well beyond one year’s pay.
From 1 January 2027, a successful unfair dismissal claimant could receive an award far exceeding £118,223. For senior or high-earning employees, employers’ financial exposure will be substantially greater than under the current regime.
This change aligns unfair dismissal compensation with discrimination and whistleblowing claims, which have always been uncapped. Employers should expect greater and less predictable potential liabilities and factor this into their settlement strategies and litigation risk assessments, especially in reorganisation and restructuring scenarios. Robust dismissal procedures will be more crucial than ever to avoid costly claims.
Why Are Standard Probation Periods No Longer a Low-Risk Exit Strategy?
Under the current legal framework, probation periods serve as an administrative trial phase. Managers routinely use three-to-six-month probation clauses to evaluate an employee’s suitability. Because unfair dismissal rights do not attach until the two-year mark, extending or failing a probation period currently carries very low legal risk.
The ERA 2025 significantly alters this dynamic. With a six-month qualifying period, employers have a far shorter window in which to assess a new hire’s performance before statutory unfair dismissal protection attaches. Employers can no longer dismiss staff simply by stating they “did not pass their probation”. Once an employee has reached six months’ service, the employer must demonstrate a fair reason for dismissal, such as capability or conduct,and prove that a fair process was followed.
Best practice will be to operate probation periods of a maximum of three to four months, extendable at the employer’s discretion by no more than one month. This framework allows a decision on the employee’s continued employment to be made in good time before the six-month qualifying threshold is reached.
The financial cost of inaction is severe, and removing the compensation cap makes it even more acute. Weak onboarding processes or undocumented performance concerns will result in potentially unlimited tribunal liability. Managers can no longer afford to wait for formal six-month reviews to address capability issues; they must document performance concerns meticulously from the very first week of employment.
How Can Employment Law Health Checks Ensure HR Compliance Before 2027?
The employers who will occupy the strongest legal position in 2027 are those initiating comprehensive preparations today. Waiting until the legislation formally activates is a high-risk strategy. To secure long-term protection, businesses must conduct employment law health checks across all human resources functions.
How Should Employment Contracts Be Updated?
Existing employment contracts require immediate review. Organisations must review their documentation to ensure contractual terms remain legally robust and fit for purpose under the new statutory regime. Contracts must clearly define performance standards, notice periods, and the specific conditions under which early termination may occur, ensuring that these terms meet the six-month qualifying threshold.
How Must Probation Periods Be Restructured?
Probation clauses must transform from a mere administrative formality into a structured framework with genuine legal utility. Contracts should specify exactly how performance will be measured during the initial months of employment, with a probation period of no more than three to four months (extendable up to one month). A clearly defined probationary framework delivers essential evidence to justify a fair capacity dismissal if an employee underperforms before the six-month qualifying threshold.
Why Are Structured Onboarding Processes Important?
A documented, systematic onboarding process immediately creates clear performance expectations. When the new qualifying period takes effect, employers must be able to prove that the employee understood what was required from the outset. Detailed training records, clear job descriptions and documented induction programs provide the necessary foundation to manage underperformance legally and fairly.
When Should Managers Implement Formal Performance Interventions?
The transition from informal feedback to formal, early intervention is critical. Managers must address capability or conduct issues as soon as they arise. If an employee struggles during their first month, managers must document the feedback provided, the support offered, and the targets set. This early paper trail is vital for demonstrating that a subsequent dismissal was reasonable and procedurally fair.
How Should Internal Disciplinary Procedures Be Aligned?
Internal disciplinary and capability frameworks must be reviewed to reflect the new six-month qualifying period. Because employers must follow fair procedures within the first six months of employment, disciplinary policies must outline clear, consistent steps for managing short-service staff. Providing comprehensive training to line managers on these updated procedures is essential to prevent costly procedural errors and, given uncapped compensation, potentially ruinous tribunal awards.
What Immediate Steps Should UK Employers Take to Prepare for 2027?
The legal environment is changing rapidly. Waiting until January 2027 to adapt your internal policies is an exceptionally high risk approach. Organisations must immediately review their HR systems while ample time remains to implement structural changes and train management personnel. Key actions include:
- Audit all existing employment contracts and update them to reflect the six-month qualifying period framework.
- Restructure probation periods to a maximum of three to four months, extendable by up to one month.
- Implement documented, structured onboarding and induction programs with clear performance benchmarks.
- Train all line managers on the early, formal performance intervention and record-keeping requirements.
- Review and update disciplinary and capability procedures for short-service staff.
- Reassess litigation risk and settlement strategies in light of uncapped compensation awards.

Frequently Asked Questions: Employment Rights Act 2025
Does the ERA 2025 give employees unfair dismissal rights from day one?
No. The original day-one proposal was amended before the Bill became law. From 1 January 2027, the qualifying period reduces from two years to six months. Employees require 6 months’ continuous service before they can bring an unfair dismissal claim (except in cases of automatic unfair dismissal, which has always carried day-one protection).
When do the new unfair dismissal protections take effect?
The six-month qualifying period and the removal of the compensation cap both take effect on 1 January 2027. Employees with six months’ service on that date will be protected immediately. New hires from July 2026 onwards must have served for 6 months before the protections apply.
What are the financial risks of ignoring the upcoming changes?
From 1 January 2027, employers face two compounding risks. First, employees can bring unfair dismissal claims after only 6 months of service, rather than 2 years. Second, and critically, the statutory cap on compensation is removed entirely. A successful claimant could receive an uncapped award based on actual and projected losses, potentially exceeding the current £118,223 ceiling. Employers who dismiss staff without following proper procedures face potentially substantial, unpredictable liability.
What are the main legal risks during the transition period?
The main risk involves employing staff under outdated contracts and informal management practices. Staff recruited before July 2026 will immediately gain enhanced protections on 1 January 2027, potentially without the necessary performance documentation in place. Employers should audit their current workforce and ensure that all short-service employees are subject to structured performance management from today.
What alternative exist to traditional probation periods?
Instead of relying on lengthy probationary clauses, employers should apply structured initial evaluation systems of three to four months (extendable by up to one month). These must include documented performance reviews, explicit capacity targets and immediate formal intervention protocols. Critically, any dismissal decision must be made before the six-month qualifying threshold, with appropriate documentation in place.
Which businesses are the most affected?
All UK employers are affected, but businesses with high staff turnover, informal management structures, or those reliant on rapid dismissals during extended probation periods will face the most significant operational and financial disruption. The removal of the compensation cap disproportionately increases the employers’ risk for higher-earning employees.
