Employment tribunal time limits for healthcare staff

The time limit doubled on 1 October 2026

The Employment Rights Act 2025 extended the standard time limit for tribunal claims from three months to six months. The change started on 1 October 2026. The longer limit covers most claims, including unfair dismissal, discrimination, unlawful deductions from wages and detriment for whistleblowing.

Which limit applies depends on the date of the problem, called the "relevant date" in the regulations. If the relevant date falls before 1 October 2026, the three-month rule still governs the claim. A few claims, such as statutory redundancy pay and equal pay, already had a six-month limit.

Say a hospital pharmacist is dismissed with a last day of employment on 30 September 2026. The three-month rule applies. A colleague dismissed on 2 October 2026 has six months. Two people in the same team can face different deadlines, so check the date for your own claim.

When the clock starts

• Unfair dismissal: the effective date of termination. This is usually the last day of your notice, or the day you were dismissed if you got no notice.
• Wages: the date you were paid the wrong amount. For a series of deductions, the date of the last one.
• Discrimination: the date of the act. Where conduct continued over a period, the end of the period.
• Detriment for whistleblowing: the date of the act or failure. For a series of similar acts, the last one in the series.

One dispute can produce several claims with different start dates. A locum nurse with an unpaid holiday claim and a discrimination claim needs both dates checked separately.

How to count six months less one day

Add six calendar months to the date of the problem, then take away one day. If you were underpaid on 10 October 2026, your last day to notify Acas is 9 April 2027. Under the old rule, a problem on 10 August 2026 gave a last day of 9 November 2026.

Do not plan around the final day. Online forms fail, post is slow and an adviser needs time to read your papers. Aim to contact Acas several weeks before the deadline.

Acas early conciliation pauses the clock

Before most tribunal claims you must notify Acas. Acas then offers early conciliation, where a conciliator speaks to you and your employer separately to see whether the dispute can settle. Both sides can choose whether to take part. The notification itself is a legal requirement, and you need the certificate number to make your claim.

Section 207B of the Employment Rights Act 1996 sets the timing rule. The clock stops from the day after you notify Acas until the day you receive the early conciliation certificate. If your time limit would run out during conciliation or within one month after the certificate, you get until one month after the date you receive the certificate. Early conciliation lasts up to 12 weeks for notifications made from 1 December 2025.

The pause works only if you notify Acas inside your original time limit. A notification after the deadline does not restart the clock. You can call the Acas helpline on 0300 123 1100, Monday to Friday, 8am to 6pm.

If the deadline has passed

You can still submit a late claim, and a judge decides whether to accept the claim. For most claims under the Employment Rights Act 1996, including unfair dismissal and whistleblowing detriment, you must show a claim in time was "not reasonably practicable" and you then acted within a reasonable further period. For discrimination claims under the Equality Act 2010, the tribunal has a wider power to extend time where an extension is fair in all the circumstances. Tribunals enforce time limits strictly. Acas guidance states going through a grievance, disciplinary or appeal process does not change your time limit.

Northern Ireland: different tribunals and a different clock

In Northern Ireland, claims go to the Industrial Tribunals, or to the Fair Employment Tribunal for discrimination on grounds of religious belief or political opinion. Since 27 January 2020 you must notify the Labour Relations Agency (LRA) before most claims. LRA early conciliation lasts up to one month. A conciliation officer can extend the period by 14 days where both sides agree and a settlement looks likely.

The October 2026 change for Great Britain does not extend most Northern Ireland time limits. Claims there usually must be presented within three or six months of the incident, depending on the type of claim. Check the limit for your claim with the LRA or nidirect early conciliation guidance (opens another website).

What to do this week

1. List the date of each problem: the dismissal, the pay date, the act you want to complain about.
2. Count the deadline for each one and put the earliest date in your diary.
3. Notify Acas online or by phone well before the date. In Northern Ireland, notify the LRA.
4. Book advice. Union members can contact their union, such as the Pharmacists' Defence Association, the BMA or the RCN. Whistleblowers can call Protect. Read how to prepare for an advice appointment.
5. Carry on with your grievance if you want to, but do not let the grievance timetable set your tribunal deadline.
6. Keep the early conciliation certificate and write down the date you received the certificate.

A deadline on top of a dispute at work can disrupt sleep and concentration. Ask someone you trust to check your dates. For the effect on your health, a GP or a service such as NHS Practitioner Health or Pharmacist Support can help, separate from the legal question. If the dispute follows a concern you raised, read what to do if treatment changes after speaking up. If the dispute is about new terms, read when an employer changes your contract.
