UK Employment Tribunal: Complete Guide for London Workers

If your employer has treated you unfairly, dismissed you without proper cause, or discriminated against you at work, the UK Employment Tribunal is the legal route most London workers turn to for justice. It can feel intimidating at first. Legal jargon, strict deadlines, and unfamiliar forms don’t exactly put anyone at ease, especially when you’re already dealing with the stress of a workplace dispute.

This guide breaks down everything you need to know about bringing a claim to an Employment Tribunal in London, written in plain English rather than legalese. We’ll walk through who can claim, what counts as a valid claim, the step-by-step process from ACAS conciliation to a final hearing, how much it costs (spoiler: usually nothing), and what compensation you might realistically expect in 2026.

Whether you’re dealing with unfair dismissal, workplace discrimination, unpaid wages, or a redundancy that doesn’t add up, understanding how the tribunal system works puts you in a far stronger position. London has one of the busiest tribunal caseloads in the country, so knowing the process before you start can save you weeks of confusion and, more importantly, help you avoid missing the deadlines that could sink your case entirely.

Let’s get into it.

What Is a UK Employment Tribunal?

A UK Employment Tribunal is an independent judicial body that hears disputes between employees (and sometimes workers or job applicants) and their employers. It operates separately from the ordinary civil courts and specialises entirely in employment law issues, things like unfair dismissal, discrimination, unpaid wages, redundancy disputes, and breaches of contract.

Tribunals are designed to be more accessible than the county court system. Hearings are somewhat less formal, and in theory, you don’t need a lawyer to represent yourself, though in practice, legal advice often makes a real difference to the outcome. Each case is typically heard by an Employment Judge, sometimes sitting alone and sometimes alongside two lay members with experience in industrial relations, depending on the type of claim.

For London workers, the tribunal system is administered through Employment Tribunals England and Wales, part of HM Courts and Tribunals Service. Claims from Greater London are generally allocated to Central London Employment Tribunal or one of the other regional hearing centres, depending on where your employer is based and where you worked.

Who Can Bring a Claim to a London Employment Tribunal?

Not everyone has the same rights when it comes to bringing a claim, and this trips up a lot of people. Your employment status matters enormously here.

• Employees generally have the widest range of protections, including the right to claim unfair dismissal (once they’ve built up the qualifying service).
• Workers (a category between employee and self-employed contractor) have fewer rights, but can still bring claims for things like unpaid holiday pay, unlawful deductions from wages, and discrimination.
• Job applicants can bring discrimination claims even if they were never actually hired.
• Self-employed contractors generally have the fewest protections, though many people are misclassified as self-employed when they’re actually workers or employees in the eyes of the law, and it’s worth checking this if you’re unsure.

One of the biggest changes on the horizon is the Employment Rights Act 2025, which is gradually lowering the qualifying period for unfair dismissal claims from two years down to just six months. This is a significant shift for London workers in particular, given the city’s high rate of job mobility and shorter average tenures in sectors like finance, hospitality, and tech.

Common Types of Employment Tribunal Claims

London workers bring a wide variety of claims to tribunal each year. The most common categories include:

Unfair Dismissal

This is one of the most frequent claim types. Unfair dismissal covers situations where an employee is dismissed without a fair reason or without a fair process being followed, even if the underlying reason might have been legitimate.

Constructive Dismissal

This applies when you resign because your employer’s conduct has fundamentally breached your contract, effectively forcing you out. You’ll need to show the breach was serious enough that you had no reasonable choice but to leave.

Discrimination Claims

Covered under the Equality Act 2010, discrimination claims relate to unfair treatment based on a protected characteristic: age, disability, gender reassignment, marriage or civil partnership, pregnancy and maternity, race, religion or belief, sex, or sexual orientation.

Unlawful Deduction of Wages

If your employer has withheld pay, failed to pay the National Minimum Wage, or made deductions you didn’t authorise, this is a common and often straightforward claim to bring.

Redundancy Disputes

These include claims that a redundancy process was unfair, that selection criteria were discriminatory, or that statutory redundancy pay wasn’t calculated correctly.

Whistleblowing Claims

Employees who suffer detriment or dismissal after raising a genuine concern about wrongdoing (a “protected disclosure”) can bring a claim, and compensation in these cases is uncapped.

Breach of Contract

Claims relating to notice pay, unpaid bonuses, or other contractual entitlements can also be brought before a tribunal, up to a limit of £25,000 for claims arising on termination of employment.

London Employment Tribunal Locations

If you work or live in Greater London, your case will typically be heard at one of the following hearing centres, though the exact venue depends on your case and current tribunal capacity:

• Central London Employment Tribunal – Victory House, near Holborn
• East London Employment Tribunal – Vernon House, Stratford
• South London Employment Tribunal – based near Croydon
• Watford Employment Tribunal – frequently used for cases involving North and West London employers

Hearing venues can shift depending on caseload, so always check the confirmation letter or email from HM Courts and Tribunals Service for your specific date and location rather than assuming.

Step-by-Step: How to Bring a UK Employment Tribunal Claim

Step 1: ACAS Early Conciliation

Before you can bring almost any claim to an Employment Tribunal, you must first contact ACAS (the Advisory, Conciliation and Arbitration Service) to start Early Conciliation. This is a mandatory step, not an optional one. ACAS will contact your employer to see whether the dispute can be resolved without a tribunal hearing at all.

You’ll be given an EC Certificate once this process ends, whether or not it results in a settlement, and you’ll need the certificate number when you submit your claim form. Early Conciliation also pauses the clock on your time limit, which matters enormously given how strict the deadlines are (more on that below).

According to <cite index=”14-1″>official guidance, tribunal fees were abolished in 2013 and ruled unlawful by the Supreme Court in 2017</cite>, and Early Conciliation through ACAS remains completely free for both employees and employers.

Step 2: Filing Your ET1 Claim Form

Once conciliation has ended (or your ACAS certificate has been issued), you can submit an ET1 claim form online through the government’s employment tribunal portal. This form asks you to set out the details of your claim, your employment history, and the outcome you’re seeking.

Be thorough here. A vague or incomplete ET1 can weaken your case from the outset, and amending it later isn’t always straightforward. It’s worth taking your time, gathering supporting documents (payslips, emails, disciplinary letters, contracts) before you submit.

Step 3: The Employer’s Response (ET3)

Your employer then has 28 days to submit an ET3 response form, setting out their side of the dispute. If they fail to respond in time, the tribunal may proceed to decide the case based on your evidence alone, though this doesn’t happen automatically.

Step 4: Case Management and Preliminary Hearings

For more complex claims, particularly discrimination or whistleblowing cases, the tribunal will often hold a preliminary hearing first. This is where the judge sets out timetables, identifies the legal issues in dispute, and may deal with any preliminary points, such as whether you were an employee at all, or whether your claim was brought within the time limit.

Step 5: The Final Hearing

At the final hearing, both sides present evidence and are usually cross-examined. Straightforward claims (like unpaid wages) might be resolved in a single day. More complex discrimination or unfair dismissal cases involving multiple witnesses can run for several days or even weeks. The tribunal will then issue a written judgment, either on the day or, more commonly, at a later date.

Employment Tribunal Time Limits Every London Worker Should Know

This is arguably the most important section of this entire guide, because missing a deadline can end your claim before it even begins.

• Most claims (unfair dismissal, discrimination, unlawful deductions) must be started within three months less one day of the event you’re complaining about, or the date your employment ended.
• Redundancy pay claims generally have a six-month time limit.
• The ACAS Early Conciliation process pauses this clock, but it doesn’t reset it, so don’t assume you have unlimited time just because you’ve contacted ACAS.
• Tribunals do have limited discretion to extend deadlines in exceptional circumstances, but this is the exception, not the rule, and you shouldn’t rely on it.

If you’re even slightly unsure about your deadline, it’s far safer to start the ACAS process immediately than to wait and find out later that you’ve missed your window.

Does It Cost Money to Bring a Claim?

For most London workers, no. Employment Tribunal fees were scrapped back in 2017 after the Supreme Court found the previous fee regime unlawful, and as of 2026, there is still no fee to submit an ET1 claim form or to attend a hearing. There has been ongoing government discussion about reintroducing a modest issue fee, but this has repeatedly been ruled out, with the Justice Secretary confirming that tribunals will remain free to access rather than pricing workers out of justice.

That said, “free” doesn’t mean cost-free overall. Here’s what you should budget for:

• Legal representation, if you choose to instruct a solicitor or barrister, which is not required but is often advisable for complex cases
• Loss of earnings if you need to take time off work to attend hearings
• Expert reports, in some discrimination or personal injury-adjacent claims

Crucially, tribunals in England and Wales generally don’t order the losing side to pay the winner’s legal costs, unlike ordinary civil litigation. Costs orders are only made in limited situations, such as where a party has acted unreasonably or brought a claim with no reasonable prospect of success. This “no costs” principle is a big part of why the tribunal system was designed to be accessible without a lawyer.

How Much Compensation Can You Get?

This depends heavily on the type of claim you’re bringing.

Unfair Dismissal Awards

Unfair dismissal compensation is made up of two parts:

1. A basic award, calculated using your age, length of service, and weekly pay (capped at £751 per week from April 2026).
2. A compensatory award, covering your actual financial losses, currently capped at £123,543 or 52 weeks’ gross pay, whichever is lower.

Worth noting: under the Employment Rights Act 2025, this compensatory cap is due to be removed entirely from 1 January 2027, which will represent a major shift in how much workers can potentially recover.

Discrimination Awards and Vento Bands

Discrimination claims are different, there’s no statutory cap. Alongside compensation for lost earnings, tribunals award damages for “injury to feelings” using guidance known as the Vento bands, updated annually. For claims presented from April 2025, these bands are roughly:

• Lower band: £1,200 to £12,000, for less serious, one-off incidents
• Middle band: £12,000 to £36,400, for cases that don’t merit the top band
• Upper band: £35,200 to £60,000, for the most serious, sustained cases of discrimination

Awards above £60,000 are possible but genuinely rare, reserved for the most exceptional circumstances.

Do You Need a Solicitor for an Employment Tribunal Claim?

Not necessarily, but it depends on the complexity of your case. Straightforward claims, such as unpaid wages or a simple notice pay dispute, are often manageable without legal representation. Many London workers represent themselves successfully, particularly with support from a trade union representative if they’re a member.

For more complex cases, particularly discrimination or whistleblowing claims where the legal tests are more nuanced and cross-examination more demanding, professional representation can meaningfully improve your chances. Some options worth exploring:

• Trade union legal support, often free if you’re a member
• Citizens Advice, for general guidance on your options
• No win, no fee solicitors, common for stronger unfair dismissal and discrimination cases
• Legal expenses insurance, sometimes bundled into home or car insurance policies without people realising it

For authoritative, up-to-date guidance on your rights and the claims process, ACAS provides detailed advice on making a tribunal claim, and the government’s own employment tribunal guidance on GOV.UK is worth reading before you file anything.

What Happens at a London Employment Tribunal Hearing?

Walking into a hearing for the first time can be nerve-wracking, so here’s roughly what to expect:

• Hearings are open to the public, though they’re generally far less formal than a criminal court.
• You’ll present your evidence, often through a written witness statement read out loud, followed by cross-examination from the other side.
• The Employment Judge (sometimes with two lay panel members) will ask clarifying questions throughout.
• Judgments are sometimes given orally on the day, but for more complex cases, a written judgment follows several weeks later.
• Many hearings in London are now conducted partly or fully via video link, following changes accelerated during the pandemic years, though final hearings for contested facts are still often in person.

Tips for London Workers Preparing an Employment Tribunal Claim

A few practical pointers that make a genuine difference:

• Keep a written record of incidents as they happen, dates, names, what was said. Memory fades, and contemporaneous notes carry real weight.
• Don’t sit on your rights. Given the tight three-month time limit, start the ACAS process the moment you suspect you may have a claim, even if you’re still deciding whether to proceed.
• Gather documentary evidence early, including payslips, contracts, appraisal records, and any relevant emails or messages, before access to your work systems is cut off.
• Be realistic about outcomes. Most tribunal claims settle before reaching a final hearing, so it’s worth thinking through what an acceptable settlement looks like to you.
• Consider mediation or settlement discussions seriously; a negotiated outcome can be quicker, less stressful, and financially comparable to a tribunal award, without the uncertainty of a hearing.

Recent Changes: The Employment Rights Act 2025 and What’s Coming

London workers should be aware that UK employment law is going through one of its biggest overhauls in decades. Key changes from the Employment Rights Act 2025 include:

• The qualifying period for unfair dismissal protection is being reduced from two years to six months.
• The compensatory award cap for unfair dismissal is set to be removed entirely from 1 January 2027.
• “Fire and rehire” practices are set to become automatically unfair dismissal, with implementation now expected around January 2027.
• The new Fair Work Agency is being established to strengthen enforcement of employment rights across the UK.
• Statutory Sick Pay is being reformed, becoming payable from day one rather than after a three-day waiting period.

These changes are being phased in gradually, so it’s worth checking the latest position on GOV.UK before assuming any specific rule applies to your situation, particularly given how much is shifting between now and 2027.

Frequently Asked Questions

How long does an Employment Tribunal claim take in London? Simple claims can be resolved within a few months, especially if they settle early. More complex discrimination or multi-day unfair dismissal claims can take a year or longer from ET1 submission to final judgment, largely due to tribunal backlogs.

Can I still work while my claim is ongoing? Yes. Bringing a tribunal claim doesn’t affect your current employment status unless the claim itself relates to a dismissal that’s already happened.

What if I lose my case? In most situations, you won’t be ordered to pay your employer’s legal costs, provided you acted reasonably throughout. You simply won’t receive compensation.

Can I bring a claim if I was self-employed? Generally no, unless you can show you were actually a “worker” or “employee” despite your contract’s label, something increasingly recognised as misclassification.

Is there a way to resolve disputes without going to tribunal at all? Yes. Many disputes settle through ACAS Early Conciliation, direct negotiation, or a formal settlement agreement, often the fastest and least stressful route for everyone involved.

Conclusion

Bringing a claim to a UK Employment Tribunal can feel overwhelming, but London workers who understand the process, from ACAS Early Conciliation through to a final hearing, are far better equipped to protect their rights and pursue fair compensation. The system remains free to access, the time limits are strict but manageable if you act early, and compensation for claims like unfair dismissal and discrimination has increased meaningfully in 2026, with further reform on the horizon under the Employment Rights Act 2025.

Whether your situation involves unfair dismissal, workplace discrimination, unpaid wages, or a messy redundancy process, the key takeaway is simple: know your deadlines, gather your evidence early, and don’t be afraid to seek advice, whether from a union, a solicitor, or a free service like Citizens Advice, before deciding how to move forward.
