UK Unfair Dismissal Changes 2027: What Employers Must Do

From 1 January 2027, most employees in England, Scotland, and Wales will qualify for ordinary unfair dismissal protection after just six months on the job, down from the current two years. At the same time, the cap on compensatory awards in unfair dismissal cases will be removed entirely. For employers, that means a much shorter runway to get a hiring decision right, and a much larger financial consequence if it goes wrong.

The date itself is close: less than six months away. Between now and then, it’s worth rethinking who you hire, how thoroughly you assess them, and how you manage the first months of employment. That applies to a UK-headquartered business just as much as to a US, Canadian, or Australian employer with a UK subsidiary, a UK entry point for expansion, or UK staff managed from another market. Multinational employers often feel this one more sharply, since UK employment law rarely mirrors the rules a global HR team applies elsewhere, and this change widens that gap.

What’s actually changing

Under the Employment Rights Act 2025, four specific changes take effect from 1 January 2027:

• Qualifying period for ordinary unfair dismissal protection: reduced from 2 years to 6 months
• Qualifying period for the right to request written reasons for dismissal: reduced from 2 years to 6 months
• Qualifying period for protection against unfair dismissal on grounds relating to spent convictions: removed entirely
• Cap on compensatory awards for unfair dismissal: removed

In practical terms, an employee who has been with your organisation for six months will soon have the same core protection it currently takes two years to earn, and if a tribunal finds the dismissal unfair, there will no longer be a ceiling on what it can award in compensation.

What stays the same

Day-one protections against discrimination and against automatically unfair grounds for dismissal are unaffected. Statutory and contractual notice periods remain the same. The way tribunals calculate compensatory awards, based on actual and projected losses as evidenced by the claimant, hasn’t changed. Only the ceiling on that calculation is disappearing, and the government’s own guidance notes that most current unfair dismissal awards already sit well below the existing cap, so the removal will matter most for higher-value cases, not the typical dismissal.

The non-renewal of a fixed-term contract on expiry still counts as a dismissal, and that doesn’t change. Worth flagging for employers who use short fixed-term contracts to trial staff: if an employee reaches six months’ service by the time their contract expires, they’ll have already qualified for unfair dismissal protection, so a non-renewal at expiry stops being automatically low-risk once that threshold is crossed.

It’s also worth being precise about what “uncapped” compensation actually means in practice. Removing the statutory cap does not mean tribunals award unlimited sums regardless of the facts. Compensatory awards are still governed by section 123 of the Employment Rights Act 1996, which requires the award to reflect the claimant’s actual proven loss, and tribunals can still apply a Polkey deduction, reducing the award where the employer can show the employee would likely have been dismissed anyway had a fair process been followed. The duty on the claimant to mitigate their loss also remains.

The ceiling is gone, but the tribunal is still working out what the employee actually lost. For employers, a fair, documented process is now the strongest protection against a large award, cap or no cap.

Who this applies to

The changes apply across England, Scotland, and Wales. Northern Ireland is not included, as unfair dismissal legislation there is devolved separately. Employers with operations across the UK should note that the change doesn’t land uniformly nationwide.

The current two-year qualifying period still applies to any dismissal with an effective termination date before 1 January 2027. What triggers the new rules is the date of the dismissal itself, not the date the employee was hired.

For international employers, this is worth being explicit about: it’s a UK-specific change. It won’t automatically extend to a parent company’s home-market rules, and the US, Canada, and Australia all handle qualifying periods, notice, and compensation differently. A global HR policy built around one market’s assumptions can create real exposure once applied to UK headcount without adjustment, and that gap tends to surface only after a dismissal is already underway.

Why this raises the stakes on hiring quality

A two-year qualifying period gave employers a long window to identify a poor fit and part ways with comparatively low risk. A six-month window compresses that significantly, and removing the compensation cap raises what’s at stake if a dismissal within that window, or shortly after it, is later found unfair.

That shifts more weight onto decisions employers make well before a dismissal ever becomes a possibility: who gets hired in the first place, how thoroughly they’re assessed before an offer goes out, and how deliberately the first months of employment are managed. Probation periods, structured onboarding, and early performance review points all become more consequential when the legal protection window arrives at month six instead of year two.

This is a direct, practical reason to treat candidate assessment and early-tenure management as one continuous process instead of two separate problems. Getting the hire right reduces how often you’re relying on the dismissal process at all.

What employers should do now

• Review probation period length and structure. If your standard probation period is three months, consider whether it gives you enough runway to properly assess fit before the six-month qualifying period begins.
• Strengthen reference and background-check processes. More weight now sits on decisions made before day one.
• Tighten early performance management. Build in a clear, documented review point well before the six-month mark, not after it.
• Audit fixed-term contract renewal practices. Remember that non-renewal still counts as a dismissal, so the same qualifying-period logic applies.
• Seek independent legal advice before updating employment policies. This article outlines what’s changing and why it matters for hiring; it isn’t a substitute for legal guidance on your specific contracts, policies, or existing cases.

Where recruitment quality fits into this

A recruitment partner can’t promise anything about legal risk, and shouldn’t try to. The real shift is in the value of a thorough, well-assessed hire, especially for an employer managing UK headcount inside a wider international operation. A shorter qualifying period and an uncapped compensation exposure both raise the cost of a mismatched hire discovered late, and that cost is harder to absorb quietly when the hiring decision was made from outside the UK in the first place. Structured candidate assessment, honest reference verification, and a properly managed early-tenure process matter more under these rules, whether you’re building a UK team from scratch or running one alongside operations in the US, Canada, or Australia.

Global Recruitment Experts works with employers across 50+ countries on this kind of cross-border hiring, including through recruitment process outsourcing that builds consistent, compliant hiring practices across multiple markets rather than treating each country as a one-off.

Compliance in other markets:

If your organisation also hires in the United States or Canada, both are tightening enforcement in parallel. See PERM recruitment compliance for U.S. employers and Canada’s 2026 TFW employer eligibility rules for what’s changed in each.
