Employment Tribunal Claims in 2026: A Plain-English Guide for UK Employees and Employers
Bringing an employment tribunal claim UK 2026 style means one big change to plan around: from October 2026 the time limit for most claims doubles from three months to six. This guide explains what tribunals decide, exactly how the deadlines work before and after the change, the mandatory ACAS early conciliation step, how to complete an ET1 claim, what a hearing actually feels like, and how AI research tools can help you prepare, whichever side of the dispute you are on.
Employment tribunals decide the vast majority of workplace legal disputes in England and Wales, and they are designed, imperfectly, for people without lawyers. Whether you are an employee weighing a claim or an SME facing one, the process rewards preparation and punishes missed deadlines. Here is how it works in 2026.
Employment Tribunal Basics: Jurisdiction and Process
Employment tribunals are specialist statutory tribunals, separate from the ordinary courts, dealing with claims such as:
● Unfair dismissal under the Employment Rights Act 1996 (an unfair dismissal claim England employers most commonly face still generally requires two years' service until the qualifying period drops in 2027).
● Discrimination under the Equality Act 2010 (no service requirement at all).
● Wages claims: unlawful deductions, holiday pay, notice pay.
● Whistleblowing detriment and dismissal, protection that applies from day one with uncapped compensation, a point whistleblowing law UK SME guidance rightly emphasises.
● Redundancy payments, and failures to inform and consult under the TUPE regulations UK 2026 transfers still trigger when a business changes hands.
The shape of every case is the same: ACAS early conciliation, then an ET1 claim form, the employer's ET3 response, case management orders, exchange of documents and witness statements, and finally a hearing. There is currently no fee to bring a claim. Appeals on points of law go to the Employment Appeal Tribunal.
New Time Limits: 6 Months from October 2026
Time limits are where tribunal claims die, so read this section twice.
● The rule today: most claims must be presented within three months less one day of the act complained of (dismissal, deduction, discriminatory act). A few claims, such as statutory redundancy pay and equal pay, already have six months.
● The change: the Employment Rights Act 2025 extends the standard limit to six months, taking effect from October 2026. Claims arising before commencement remain subject to the old limit, so do not assume the new deadline applies to an existing dispute; take advice on anything borderline.
● The clock still matters. Six months is more forgiving, not forgiving: late claims are allowed only in narrow circumstances, and evidence goes stale faster than deadlines expire.
● Discrimination has its own wrinkle. The limit runs from each discriminatory act, but conduct extending over a period counts as done at the end of that period, a distinction that regularly decides whether older events can be included, and one worth advice.
For employers, longer limits mean disputes can surface months after the event, so retain documents, notes and rotas accordingly.
ACAS Early Conciliation: The Mandatory First Step
Before you can lodge almost any tribunal claim, you must notify ACAS and go through early conciliation. It is free, and it works like this:
1. You submit the short early conciliation form (online or by phone).
2. An ACAS conciliator contacts both sides and explores settlement for up to six weeks, entirely voluntarily: neither side has to engage or agree.
3. If there is no settlement, ACAS issues an early conciliation certificate with a number you must quote on the ET1. No certificate, no claim.
Two practical points. The conciliation period pauses the limitation clock, but the rules for recalculating your deadline are technical, so never treat conciliation as free time. And a settlement reached through ACAS (a COT3 agreement) is binding, so take advice before signing away a claim.
Conciliation is also where the ACAS Codes of Practice earn respect. If an employer failed to follow the Code on disciplinary and grievance procedures, a tribunal can increase compensation by up to 25%, and an employee's unreasonable failure can reduce it by the same margin. Both sides should read the Code before deciding how firm to be in negotiation.
How to Make an ET1 Claim: Step-by-Step
1. Check your deadline from the date of the act you complain about, and start early conciliation well inside it.
2. Gather the record: contract, payslips, dismissal or grievance letters, messages, and a dated chronology of events.
3. Get your certificate from ACAS once conciliation ends.
4. Complete the ET1 online. The critical box is the particulars of claim: set out, in numbered paragraphs and date order, what happened and which legal rights you say were breached.
5. Name the right respondent: the employing entity on your contract, not the manager who made the decision.
6. Submit and diarise. The tribunal serves the claim; the employer has 28 days to file its ET3 response.
7. Follow the case management orders that follow: deadlines for documents, witness statements and the hearing bundle are orders, not suggestions.
Employers on the receiving end should mirror the same discipline: calendar the ET3 deadline immediately, preserve documents, and consider whether settlement through ACAS is cheaper than defence.
What to Expect at a Tribunal Hearing
Most hearings are less theatrical than people fear. A judge sits alone or with two lay members (typical in discrimination cases). Hearings are generally public, and many shorter ones proceed by video. Evidence comes from written witness statements, tested by cross-examination on the other side's questions, with the documents in an agreed bundle.
Before the final hearing, longer or more complex cases usually have a preliminary hearing: a case-management discussion (often by phone or video) where the judge sets the timetable, identifies the legal issues and sometimes decides threshold questions such as employment status or whether a claim was in time. Treat it seriously: the list of issues agreed there becomes the skeleton of the whole case. Judicial mediation may also be offered in suitable cases, a free, judge-led attempt to settle before trial.
Three features distinguish tribunals from ordinary courts. Costs orders are the exception, not the rule, so each side usually bears its own costs win or lose. Procedure is deliberately more flexible, and judges are used to unrepresented parties. And remedies are mostly financial: compensation calculated under statutory rules, with reinstatement rare in practice. Realistic expectations, on both sides, settle more cases than optimism does.
How AI Can Help You Prepare
AI research tools have a genuine role on both sides of a tribunal case, used honestly:
● Understanding the law: what makes a dismissal unfair, what counts as a protected disclosure, how discrimination is defined, with sources you can check against the legislation.
● Organising the story: turning a shoebox of messages into a dated chronology, the single most valuable document in any employment case.
● Drafting support: a first structure for particulars of claim, a grievance letter or an ET3 response, refined by you and, ideally, checked by an adviser.
● Preparing for hearing: anticipating the questions the other side will ask about the weak points in your account.
What AI cannot do: represent you, know facts you have not told it, or replace advice on tactics and settlement value. Verify every legal point against the source before relying on it, and remember tribunals have criticised parties for citing cases that do not exist. Use AI outputs as preparation aids rather than filing them wholesale: a tribunal expects your statement and particulars in your own words, describing events you actually witnessed.
Frequently Asked Questions
Do I need a lawyer to bring a tribunal claim? No, and many claimants self-represent. For high-value or discrimination claims, professional advice pays for itself; check household insurance and union membership for cover.
How long do I have to claim in 2026? Generally three months less one day until the six-month limit commences in October 2026, and always subject to the ACAS conciliation rules. Check your specific claim type: some already differ.
Does it cost anything to claim? There is currently no tribunal issue fee. Your real costs are time, and any adviser you choose to instruct.
Can my employer make me pay their costs if I lose? Only exceptionally, for example where a claim was vexatious or conducted unreasonably. The default is each side pays its own way.
What compensation can I get for unfair dismissal? A basic award calculated like statutory redundancy pay, plus a compensatory award for losses, subject to statutory caps that are revised each April. Discrimination and whistleblowing awards are uncapped.
Key Takeaways
● Tribunal deadlines are short and strict: three months less one day now, six months for claims arising from October 2026.
● ACAS early conciliation is mandatory, free, pauses the clock, and settles a large share of disputes.
● The ET1 particulars and a dated chronology decide how seriously your case is taken; build both carefully.
● Costs rarely shift, hearings are public and mostly financial in remedy; prepare, and be realistic about value.
