How Long Does an Employment Tribunal Take?

Most employment tribunal cases take 12–18 months from start to finish. Understand the timeline, what causes delays, and how to manage expectations.

What's the typical timeline from complaint to tribunal hearing?

It usually takes 12–18 months from ACAS early conciliation to a full hearing. Here's the breakdown: ACAS conciliation (1–3 months), filing ET1 to first case management hearing (2–3 months), case management and disclosure (3–6 months), pre-hearing review (1–2 months), then the final hearing. Complex cases, especially those involving equal value expert assessments, can take 2+ years.

Why is the wait so long?

Employment tribunals are under-resourced. They're handling more claims, but the number of judges and staff hasn't grown proportionally. Simple cases take longer than they should because of admin delays. Complex cases (equal value, multiple claimants, large employers) take even longer. Some regions are faster than others — London tribunals can be quicker than rural areas, though even London can be 12+ months.

Can I speed up the process?

Partly. If both sides agree, you can skip some steps or fix some issues without a hearing (summary judgment). Keeping your case simple and well-organised helps — if your evidence bundle is messy or incomplete, there are delays. But ultimately, the tribunal's calendar controls the pace. You cannot force a hearing before the tribunal is ready.

What if my case is urgent (e.g., I need money now)?

The tribunal will not expedite just because you need money. But there's Interim Relief — if you've been unfairly dismissed, you can ask the tribunal to order reinstatement or re-engagement before the full hearing. This is rare and high-bar (must be "likely" to win). You can also apply for a swift preliminary hearing to resolve threshold issues early.

What's a preliminary hearing and how long does it take?

A preliminary hearing is a short hearing (1–2 hours) before the main trial. It's used for case management (sorting directions, disclosure), or to decide jurisdictional issues (can the tribunal even hear this case?). There's no waiting — once the case is allocated, preliminary hearings can often happen within 4–8 weeks. But the full hearing still has the long wait afterward.

Is it worth waiting 18 months for a claim?

Often yes, especially if the compensation is substantial. Back pay claims, harassment claims, and wrongful dismissals can be worth tens of thousands. Even modest claims can be worth pursuing if you have strong evidence. But consider costs — you'll need to evidence, gather documents, and prepare. Factor in emotional toll. If the claim is small (under £5,000) and you're in a hurry, settlement might be better.

What if the employer offers to settle quickly?

You can accept a settlement at any time. ACAS can help broker a settlement agreement (a legal document) that binds both sides. Settlements are usually faster and cheaper than fighting to a tribunal hearing. But don't accept too little just for speed — get advice and make sure the offer is fair.

The typical timeline: from complaint to hearing

Here's a realistic outline of how long each stage takes:

ACAS early conciliation

You contact ACAS, they try to settle. Conciliation usually takes 4–8 weeks. If successful, case ends. If not, ACAS issues a certificate, and you can file your ET1.

Filing ET1 to acknowledgement

You file your ET1 claim with the tribunal. The employer has 28 days to respond (ET3). Tribunal acknowledges receipt and assigns to a judge.

First case management preliminary hearing

A short hearing (30 mins – 1 hour) to discuss next steps. Judge sets directions: deadlines for disclosure, witness statements, expert evidence. Usually happens fairly quickly after ET3 response.

Disclosure and evidence exchange

Both sides exchange documents. If there\'s expert evidence (e.g., equal value assessment), expert reports are exchanged. This phase often has multiple directions and deadlines.

Pre-hearing review (if needed)

Optional or ordered by the judge. Parties make final submissions. Judge confirms the hearing date and duration. Some cases are struck out here if one side\'s case is clearly hopeless.

Waiting for the final hearing date

The tribunal schedules the full hearing. This is often where delays accumulate. Complex cases with multiple days booked can wait longer. Regional variations — London can be faster.

Most cases take 2–3 days. Simple cases (unfair dismissal with limited issues) might be 1 day. Complex cases (equal value, multiple claims, many witnesses) can be 5+ days.

The judge may give judgment orally at the end of the hearing, or "reserve" (take time to write it). Written judgments usually come 2–4 weeks later, though some take longer.

Total: roughly 12–18 months from ACAS contact to judgment. Add 2–4 weeks if you appeal.

Most delays are systemic, not within your control:

There are fewer judges and staff than claims. Backlogs build up, especially post-pandemic. Some regions have longer waits than others. London and Manchester are generally faster; rural areas slower.

Simple unfair dismissal cases are faster. Complex cases (discrimination, equal value requiring experts, multiple claimants) are queued longer because they need more judge time. A 5-day hearing can\'t be fitted in a 2-day slot.

Expert evidence delays

Equal value claims require an independent expert assessment. This adds 6–12 months alone. The expert must write a report, both sides respond, and the report is exchanged. Then the hearing waits in the queue.

Adjournment requests

If either party asks for a postponement, the case goes to the back of the queue. Multiple adjournments can add 3–6 months. Illness, legal team unavailability, or late evidence often triggers these.

Admin and disclosure disputes

Disputes over who has disclosed what, missing documents, or debates over scope can delay progress. Each dispute means another hearing direction.

Hearing duration: how long is the final hearing?

The length of the hearing depends on case complexity. A single issue heard by one judge might take half a day. A complex discrimination case with multiple witnesses and expert evidence might need a week.

Simple claims: basic unfair dismissal (no disputes about what happened), trivial discrimination.

Moderate complexity: unfair dismissal with disputed facts, harassment claims, single discrimination claim, straightforward equal pay.

Complex cases: multiple claims, several witnesses, expert evidence, intricate facts to resolve.

Very complex: equal value assessment, multiple claimants, large institutional discrimination, appeals.

The tribunal schedules hearings based on estimated length. If your case is estimated at 3 days but the judge reserves judgment, you won\'t hear the result for 2–4 weeks (or longer in backlogged regions).

Managing the timeline: what you can control

You can\'t speed up the tribunal\'s calendar, but you can manage your case to avoid unnecessary delays:

Keep your case simple

Single claims take less time than multiple claims. Clear, straightforward facts resolve faster than tangled disputes. If you can settle one issue, do it — reduces hearing time.

Missed disclosure deadlines cause disputes and delays. Submit evidence on time. If you need an extension, ask early and justify it. Late filings frustrate the judge and delay the hearing.

Once a hearing is scheduled, avoid postponement requests. They push you to the back of the queue. Only request adjournment if genuinely unavoidable.

Well-organised evidence bundles, clear witness statements, and thoughtful arguments can shorten the hearing. A poorly prepared case needs extra days and causes confusion.

If you can reach a settlement with the employer, you avoid the hearing entirely. This is often faster and cheaper. ACAS can broker a settlement agreement.
