How long does an employment tribunal take?

The honest answer is longer than you want and longer than anyone tells you at the start. A straightforward claim that runs all the way to a hearing commonly takes somewhere between nine months and two years from dismissal to decision. Complex claims take longer. This guide sets out where the time actually goes, so you can plan around it.

The stages, and what each one costs you in time

• ACAS early conciliation. Compulsory before you claim. Up to six weeks, though it often ends sooner if the employer will not engage.
• Lodging the ET1. Your claim form. Must be in within the deadline, which is normally three months less one day from dismissal, paused while ACAS conciliation runs.
• The employer's ET3 response. They get 28 days from being sent your claim, and extensions are commonly granted.
• Initial consideration and case management. The tribunal reviews the papers. In anything other than a simple claim there will be a preliminary hearing, often by telephone or video, to set the issues and a timetable. Getting one listed can take a couple of months on its own.
• Preparation. Disclosure of documents, an agreed bundle, and written witness statements exchanged. Typically several months, largely because it runs to the timetable the tribunal sets rather than to your urgency.
• The final hearing. A simple unfair dismissal claim may be listed for one to three days. A discrimination claim with several witnesses can run for a week or more.
• The judgment. Sometimes given on the day, often reserved and sent in writing weeks later. If compensation is disputed there may be a separate remedy hearing after that.

Why the range is so wide

Regional listing times. This is the single biggest variable and it is entirely outside your control. Waiting times differ substantially between tribunal regions, and busy regions can list a multi-day hearing well over a year ahead.

Claim type and complexity. One unfair dismissal claim with two witnesses moves far faster than a discrimination claim spanning three years, six witnesses and a disability that the employer disputes.

Preliminary issues. If the employer argues you are out of time, or not an employee, or that you are not disabled within the meaning of the Equality Act, that gets decided first, sometimes at a separate hearing months before the main one.

Postponements. Hearings get moved for witness illness, late disclosure, or simply because no judge is available on the day. A postponed hearing rarely relists quickly.

Most claims never reach a hearing

It is worth keeping in perspective: the large majority of tribunal claims settle or are withdrawn before the final hearing. Settlement can come at any point, and there are natural pressure points where it becomes more likely: shortly after the ET3 lands, after disclosure reveals what the documents actually say, and in the weeks before the hearing when the employer's legal costs start to climb steeply.

That matters for timing. If a settlement is the realistic destination, the useful question is not how long the tribunal takes, but how quickly you can get to the point where the other side takes the claim seriously.

Making the time work for you

Keep every document from the outset, and keep them organised. Cases are decided on the paperwork, and reconstructing it a year later is far harder.

Keep a running record of your job search and your losses, including applications, interviews, payslips from any new role and benefits received. Compensation for lost earnings runs to the hearing and beyond, and you are expected to show you tried to mitigate.

Hit every direction the tribunal sets. Missed deadlines cause delay at best, and strike-out applications at worst.

Look after yourself. The most underestimated cost of a tribunal is not money or time but the way it keeps a bad chapter open. That is a legitimate reason to settle, and it is not weakness.

Where advice shortens things

A specialist will usually tell you within one conversation whether your claim is the kind that settles early or the kind that has to be fought, and will price it realistically. Claims that are well pleaded from the start, with the right causes of action and a properly evidenced loss schedule, tend to settle sooner and higher, because the employer's own advisers can see where it is heading.

If you are weighing up whether to start, get that view before the three-month deadline is close. Options narrow quickly once it passes.
