How Long Does an Employment Tribunal Take? Timescales Stage by Stage

The question "how long does an employment tribunal take?" has an honest answer and a precise one. The honest answer: a contested claim that runs to a final hearing in England and Wales commonly takes well over a year from the day you first contact ACAS, and the wait for the hearing date is usually the longest part. The precise answer: there is no statutory timetable. The pace is set by case management orders made under the Employment Tribunal Procedure Rules 2024 (rule 30), by listing capacity in your region, and by how the two sides behave.

Two facts frame everything below. The backlog is at a record high: around 64,000 single claims were open at the end of March 2026, up 55% on a year earlier (MoJ, Tribunal statistics quarterly, January to March 2026). And most claims never reach a final hearing; they settle or are withdrawn, often within months. This guide is about where the time goes. For what each step involves, see the employment tribunal process step by step.

How long does an employment tribunal take at each stage?

Three rows need a note.

Early Conciliation runs for up to about 12 weeks for cases notified to ACAS on or after 1 December 2025 (the older 6-week period applies to earlier notifications), but ends as soon as either side declines to continue or the conciliator concludes a settlement is not possible. The certificate gives at least one month to lodge the ET1; see the ACAS Early Conciliation guide.

The ET3 is the one fixed clock in the process: under rule 17, the tribunal must receive the response within 28 days of the date it sent the claim form to the employer, which is days or weeks after you lodged. The case management orders that follow set every later date; from then on the long wait is for the hearing slot.

The hearing and after. Discrimination and whistleblowing claims are usually heard by a panel of three, and multi-day panel hearings are the hardest to list. Judgment may be given on the day or reserved and sent some weeks later, and a separate remedy hearing can add months; the guide to what happens at the hearing covers both. A reconsideration application must reach the tribunal within 14 days of the written judgment or reasons being sent (rule 69); an appeal to the Employment Appeal Tribunal, on a point of law only, within 42 days of the written judgment or full reasons being sent, by 4pm on the final day (Employment Appeal Tribunal Rules 1993, rule 3; GOV.UK: how to appeal).

What makes a claim take longer?

The spread between a few months and two years comes down to a few factors:

• Claim type. Discrimination, whistleblowing and combined claims need longer hearings, more witnesses and usually a three-member panel, so they routinely take 12 to 24 months from lodging to final hearing; a single unfair dismissal claim heard by a judge alone is quicker to list.
• Hearing days needed. A one-day slot is found far sooner than five days with a panel, and underestimating the days is a common cause of a part-heard hearing that resumes months later.
• The region. Listing backlogs differ between tribunal offices.
• Postponements. A hearing postponed because a judge, panel member or witness is unavailable often goes to the back of the queue.
• Preliminary issues. Time limits, disability status under the Equality Act or employment status may each need a separate preliminary hearing first.
• The state of preparation. Late or incomplete disclosure, a disputed bundle or late witness statements lead to further orders, applications and sometimes a vacated hearing date.

Together they are why a hearing date 12 to 18 months away is a realistic expectation, not a worst case.

Why do most claims finish sooner?

The timescales above describe the longest route; most claims take a shorter one. Of single claims closed in 2024/25, 40% settled through Acas conciliation, 19% were withdrawn and 3% were won at a final hearing (MoJ tribunal statistics; the employment tribunal statistics guide explains why the 3% figure is not a success rate). The earlier endings are:

• Settlement through ACAS at any stage. Conciliation does not stop at the certificate: an ACAS conciliator remains available up to the hearing, and an agreement reached that way is recorded on a COT3 form.
• A settlement agreement. The parties can settle directly in a written settlement agreement at any point up to the morning of the hearing.
• Withdrawal. A claimant can withdraw all or part of a claim at any time.
• Judicial mediation. Rule 4 requires the tribunal to encourage ACAS, judicial or other mediation wherever practicable, and in some cases an employment judge offers a private mediation day, usually raised at case management.
• No ET3 filed. Where the employer does not respond in time, the tribunal can decide the claim on the papers or fix a hearing (rule 22); see the ET3 guide.

In practice "how long will this take?" often becomes "when does a settlement make sense?", and that can be at any stage.

What does the backlog look like now?

The Ministry of Justice's latest quarterly bulletin at the time of writing, covering January to March 2026 and published on 11 June 2026, reports:

• a single-claim open caseload of around 64,000 at the end of March 2026, 55% higher than a year earlier;
• around 50,000 single claims received in 2025/26, up 39%;
• around 26,000 single claims disposed of in 2025/26, down 12%.

More claims are arriving than are being closed. Two caveats: waiting times vary by region and claim type, so a national figure is a direction of travel, not a forecast for any one case; and the bulletin gives no simple lodging-to-hearing figure for single claims, saying only that average case lengths rose between 2024/25 and 2025/26. The time-to-clearance measures sit in the quarterly tables on the tribunals statistics collection page.

A worked example in elapsed time

An illustrative timeline for a contested claim that reaches a final hearing, not a forecast or a set of deadlines: your own dates come from the tribunal's orders and, for the time limit to start a claim, the tribunal deadline calculator.

1. Week 0. ACAS notified; the tribunal time limit is paused.
2. By week 12. Conciliation ends without agreement and the certificate is issued.
3. Week 13. ET1 lodged.
4. Around week 17 or later. ET3 due, 28 days after the tribunal sent the claim to the employer.
5. Months 4 to 6. Preliminary hearing by telephone or video; case management orders issued; final hearing listed.
6. Months 6 to 10. Disclosure, bundle and witness statements, each to the ordered date.
7. Months 12 to 18. Final hearing; a multi-day discrimination claim can slip further out.
8. Afterwards. Judgment on the day or reserved for some weeks; a separate remedy hearing, if needed, weeks or months later.

A straightforward claim in a quieter region can run quicker, a complex panel case in a busy one slower; either way, it is roughly 12 to 18 months of intermittent attention, most of it waiting.

Can you speed it up?

Only partly. The wait for a hearing slot is set by listing capacity and is outside either party's control; what a claimant controls is everything that avoids adding to it. Claims tend to move faster when:

• every date in the case management orders is met, and any extension is asked for in advance;
• the hearing bundle is agreed rather than argued over, and disclosure is complete the first time;
• the claim is focused on the issues that matter, so the hearing length is estimated accurately;
• an application is made promptly if the other side falls behind the orders;
• conciliation is treated as a live option throughout, because a settlement is the only ending that arrives on a date the parties choose.

Asking for an earlier date rarely works on its own; expedited listing is unusual and tied to specific reasons such as serious ill health.

Does the time limit to claim change how long the case takes?

No. The two clocks are separate. The time limit governs when a claim must be started: for most claims it is 6 months less 1 day from the date of dismissal or the act complained of where that was on or after 1 October 2026 (3 months less 1 day if it was before then), and ACAS must be notified within that window. Once a claim is lodged in time, its length is governed by the stages above.

The clock to start is short; the case itself is long. The employment tribunal deadlines guide sets out the trigger dates and the ACAS pause in full.

Key takeaway

A contested employment tribunal claim is a commitment measured in months at best and often in years, and the backlog means that is unlikely to change soon. But the long route is the exception: most claims end earlier, by settlement or withdrawal, and conciliation stays open throughout. Knowing where the time goes, and that most of it is waiting rather than working, makes it easier to decide how much to commit. Whether a claim is worth that commitment is a separate question, covered in whether it is worth going to an employment tribunal.
