Are you ready for the January 2027 unfair dismissal changes? The path is straightforward if you act now. From 1st January 2027, the qualifying period for ordinary unfair dismissal is expected to drop from two years to six months, with retrospective effect, and compensation caps will be removed. This is UK specific and subject to final legislation and commencement regulations. In this guide, you get the essentials, a practical timeline to July 2026, and the steps to keep your processes fair, ethical, and defensible.
What changes to unfair dismissal are planned for January 2027?
The qualifying period is scheduled to reduce to six months and compensation caps will be removed from 1st January 2027,. Retrospective application means employees with six months’ service on that date would qualify for ordinary unfair dismissal rights.
Under current law, ordinary unfair dismissal rights arise under the Employment Rights Act 1996. A tribunal assesses fairness under section 98 by asking whether the employer acted reasonably in all the circumstances. You must show a fair reason, for example conduct, capability, redundancy, statutory restriction, or some other substantial reason. You must also follow a fair process. The legal framework today sits alongside the Acas Code of Practice on Disciplinary and Grievance Procedures, which tribunals take into account.
At the time of writing, these changes are scheduled for 1st January 2027, subject to final legislation and commencement regulations. Check the final Act and any commencement orders on legislation.gov.uk as they are published. The underlying law for unfair dismissal remains the Employment Rights Act 1996 until any amendments take effect.
Many employers underestimate how quickly retrospective qualifying rules can expand risk. Your workforce on 1st January 2027, will include people who immediately gain protection.
Why does a six-month qualifying period change your risk profile?
It shortens the window before unfair dismissal rights arise, so informal exits carry higher risk sooner. Processes you once reserved for longer-serving staff must now start earlier and be applied consistently.
It is easy to assume probation gives full flexibility. That is no longer safe. A shorter qualifying period means capability, conduct, and attendance issues during probation need structured management. You still retain the right to dismiss fairly for genuine reasons, but you must evidence reasonableness and process. Values-led employers also face reputational risk if dismissals feel rushed or opaque. This is where it matters most to align ethics and compliance, protecting both people and your organisation’s mission.
Ethical, green, and non-profit employers often prioritise trust and culture. A fair, well-documented process supports your values and reduces claims risk at the same time.
How does removing compensation caps affect potential exposure?
Uncapped compensation increases financial exposure, so prevention and procedure become your best defence. Even today, awards reflect actual losses and may rise for poor process.
Currently, the compensatory award for unfair dismissal is limited to the lower of 52 weeks’ pay or a statutory cap that is updated annually. You can review the latest limits in the Employment Rights (Increase of Limits) Orders on legislation.gov.uk. Tribunals also consider the Acas Code. If you unreasonably fail to follow it, a tribunal may uplift compensation by up to 25 percent, as explained by Acas.
The Acas Code of Practice allows tribunals to increase or decrease awards by up to 25 percent where either side unreasonably fails to follow the Code.
If compensation becomes uncapped, inconsistent procedures, thin documentation, and rushed decisions can create significant financial and reputational risk. Balanced, timely processes reduce both.
What should you do before July 2026 to prepare?
Use July 2026 as your implementation deadline. Employees hired on or before 1 July 2026 who have not yet reached two years’ service may gain protection on 1 January 2027.
Timeline plan:
- From December 2025: Audit policies and contracts. Ensure your disciplinary, capability, attendance, and probation clauses are current and accessible. Map where line managers need clearer guidance. If you need support, our HR Services include audits and compliant templates.
- April 2026 – June 2026: Update templates and letters. Refresh investigation, hearing, and outcome documents. Align your equality and reasonable adjustments steps with the Equality Act 2010. Build a manager toolkit and short training modules. Train managers. Run practical workshops on investigations, note-taking, and chairing hearings. Introduce checklists and escalation triggers
- By 1st July 2027,: Go live with new processes. Apply fair procedures to all staff with six months’ service as standard. Confirm who will chair hearings and who will hear appeals.
- July to December 2026: Stress test. Run mock cases, spot-check files, and improve record keeping. Fix any bottlenecks before January 2027.
- 1st January 2027: Day-one operational check. Confirm your investigation capacity and appeal routes. Re-brief managers and reissue quick-reference guides.
Most small organisations can complete a policy and training refresh in eight to twelve weeks. Larger multi-site teams may need three to six months.
How should you manage probation fairly under the new rules?
Treat probation as structured performance management with clear goals, reviews, and records. You can still end employment during probation, but you must act reasonably and evidence your process.
Checklist for ethical probation management:
- Set measurable objectives in writing. Share what good performance looks like and any training needed.
- Run regular reviews. Hold at least one mid-point review and a final review before probation ends.
- Record feedback and support. Note training, shadowing, and any reasonable adjustments you consider.
- Use warnings proportionately. If concerns arise, issue a written warning and a short improvement plan.
- Extend probation only with reason. Explain why, how long, and what success requires. Confirm in writing.
- Offer a fair meeting before any decision. Let the employee respond, be accompanied, and see key evidence.
We have seen probation outcomes improve when managers use short, weekly check-ins. Small, frequent feedback loops prevent surprises.
What does a fair dismissal process look like in practice?
A fair dismissal follows a reasonable investigation, a hearing with evidence, and a balanced decision with appeal. The Acas Code provides the procedural backbone.
Follow these steps:
1) Investigate promptly and impartially. Identify witnesses, collect documents, and separate the investigating and hearing roles where possible. Keep notes. Where complexity is high, consider independent support through our Investigations service.
2) Notify the employee in writing. Set out the allegations or concerns, possible outcomes, and the right to be accompanied under section 10 of the Employment Relations Act 1999.
3) Hold a hearing. Give reasonable notice, share evidence in advance, and allow the employee to present their case and any mitigation.
4) Decide reasonably. Apply a band of reasonable responses. Consider consistency with past cases and any relevant policies.
5) Confirm the outcome in writing. Explain the reasons, the evidence relied upon, and the right of appeal.
6) Hear an appeal with fresh eyes. Use a different manager where possible, review the decision, and confirm the final outcome in writing.
Tribunals assess procedural fairness with reference to the Acas Code of Practice and the reasonableness test in the Employment Rights Act 1996, section 98.
How do these changes interact with redundancy, TUPE and fixed-term contracts?
They do not remove your obligations in redundancy, TUPE, or fixed-term scenarios. They do tighten timelines for fair process and consultation.
- Redundancy: You still need a genuine redundancy situation, a fair pool and selection criteria, and meaningful consultation. Collective consultation rules remain, including minimum consultation periods for large-scale redundancies. If you are restructuring, our Redundancy, Restructuring & TUPE support can help you plan and deliver fair outcomes.
- TUPE transfers: Dismissals connected to a transfer without an economic, technical, or organisational reason with workforce changes risk being automatically unfair. Processes and documentation matter.
- Fixed-term contracts: Non-renewal can be a dismissal. You should use a fair process, give notice, consult, and consider alternatives where reasonable.
What this means for customers of ethical employers:
Transparent consultation and clear documentation build trust. People accept change more readily when they see fair, consistent steps.
Why is July 2026 a practical cut-off for employers?
Because employees hired on or before 1st July 2026 who have six months’ service by 1st January 2027 may gain unfair dismissal protection on that day. Your processes must be ready before then.
Think of July 2026 as your last safe window to roll out new documentation, train managers, and fix weak points. From that date, your new starters reach the six-month mark just as the regime is expected to bite. This is the moment to shift from reactive problem solving to proactive risk management.
Key actions by July 2026:
- Finalise policy and template updates
- Train people managers on investigations and hearings
- Set clear probation review timetables
- Establish appeal routes and decision-maker capacity
- Improve case management and record keeping

FREQUENTLY ASKED QUESTIONS
What is changing about unfair dismissal in January 2027?
The qualifying period is set to reduce to six months and compensation caps will be removed. In practice, this means:
- Employees with six months’ service by 1st January 2027 are expected to gain ordinary unfair dismissal rights.
- You will still need a fair reason and a fair process to defend decisions.
- The Acas Code remains central to procedural fairness and potential award uplifts.
Why does the six-month qualifying period matter for small employers?
It brings unfair dismissal risk forward, so informal exits become riskier much sooner. You should:
- Introduce structured probation reviews, improvement plans, and written warnings where needed.
- Train managers to run basic investigations and hearings early.
- Keep consistent notes and letters to evidence reasonableness.
What is the legal test for unfair dismissal under current law?
Tribunals ask if you had a fair reason and acted reasonably in all the circumstances. They consider:
- The potentially fair reasons in the Employment Rights Act 1996, section 98.
- Your adherence to the Acas Code of Practice on Disciplinary and Grievance Procedures.
- Consistency with past decisions and the quality of your investigation.
What happens if we do not follow the Acas Code of Practice?
Tribunals can adjust compensation by up to 25 percent for unreasonable failure to follow the Code. This includes:
- Not giving notice of allegations or evidence in advance of a hearing.
- Denying the right to be accompanied.
- Skipping an appeal or failing to investigate proportionately.
How do we manage probation fairly if concerns arise?
Treat probation as structured performance management with timely support and records.
Practical steps:
- Give clear objectives and early feedback, then a short improvement plan if needed.
- Hold a fair meeting, allow representation, and confirm outcomes in writing.
- Consider an extension with reasons and support, or a reasoned termination.
How should we prepare by July 2026?
Use July 2026 as your go-live date for updated processes and training.
Focus on:
- Updating disciplinary, capability, attendance, and probation policies and letters.
- Training managers on investigations, hearings, and documentation.
- Setting up appeal routes and case tracking to improve consistency.
What evidence is essential to defend a dismissal?
You need clear, contemporaneous records that show reasonableness and process. Include:
- Investigation notes, witness statements, and relevant documents.
- Invitation, outcome, and appeal letters with reasons and evidence.
- A record of training, support offered, and reasonable adjustments considered.
Do these changes affect redundancy and TUPE dismissals?
Your duties in redundancy and TUPE remain, but timelines and documentation matter more.
Remember:
- Redundancy still requires fair selection and meaningful consultation.
- TUPE-related dismissals without an economic, technical, or organisational reason risk being automatically unfair.
- Fixed-term non-renewal can be a dismissal and must be handled fairly.
