Filing an employment tribunal claim can feel daunting, especially when you're already dealing with the stress of workplace conflict, dismissal, or discrimination. Knowing how to fill in the ET1 form correctly is the critical first step, and getting it right matters more than most claimants realise. The ET1 is the official document that formally starts your claim against an employer in England, Wales, or Scotland. Every detail you include, from the dates of events to the legal grounds you're relying on, shapes how the tribunal understands your case and what compensation you may ultimately recover.
Mistakes at this stage can be costly. Missing the strict three-month deadline, leaving key sections blank, or failing to clearly set out the facts can weaken your position or, in some cases, see your claim rejected outright. This guide walks you through each section of the ET1, explains what tribunals expect, and highlights the common pitfalls to avoid.
What Is how to fill in ET1 form?
The ET1 is the official claim form used to start a case in the Employment Tribunal in England, Wales, and Scotland. Knowing how to fill in an ET1 form correctly is the first practical step for any worker who believes their employer has treated them unlawfully - whether that involves unfair dismissal, discrimination, unpaid wages, redundancy pay disputes, or whistleblowing detriment.
At its core, the ET1 is a structured document that captures who you are, who you're bringing the claim against (the respondent), what happened, and what remedy you're seeking. It's your opportunity to set out the facts of your case clearly and formally. The tribunal, and eventually the respondent, will rely heavily on this document to understand your position, so accuracy and detail matter enormously.
The scope of the form is broad. It covers claims brought under the Employment Rights Act 1996, the Equality Act 2010, the Working Time Regulations, and various other pieces of employment legislation. You can submit it online through the gov.uk portal, by post, or in person at a tribunal office.
Context is important here. Before you can submit an ET1, you must have contacted Acas for early conciliation and received a certificate - without that reference number, your claim will be rejected. There are also strict time limits, usually three months less one day from the date of the incident, so completing the form promptly and correctly is critical to protecting your rights.
Key Benefits of how to fill in ET1 form
Understanding how to fill in ET1 form properly is often the difference between a claim that progresses smoothly and one that stalls before it begins. The ET1 is your formal introduction to the Employment Tribunal, and getting it right delivers benefits that extend well beyond simply meeting a procedural requirement.
Establishing your claim on solid ground. A carefully completed ET1 sets out the facts, dates, and legal grounds of your complaint in a way the tribunal can act on. When each section is filled in accurately, your claim is accepted first time, avoiding the frustration of rejection or requests for further information that eat into strict time limits.
Protecting your legal position. Employment claims must usually be submitted within three months less one day of the incident. Knowing how to complete the form correctly means you can lodge it confidently within that window, safeguarding rights that would otherwise be lost forever. This alone can be worth thousands of pounds in potential compensation.
Strengthening your negotiating hand. A well-drafted ET1 signals to your former employer that you understand the process and mean business. Respondents and their solicitors read the claim carefully, and a clear, focused document often prompts earlier settlement discussions through ACAS or directly, saving months of stress.
Saving money on legal fees. While tribunal representation can be costly, mastering the ET1 yourself reduces reliance on solicitors at the earliest stage. Many claimants successfully lodge their own forms and only seek advice for later steps, making justice more affordable.
Reducing emotional strain. Facing an employer after dismissal or discrimination is difficult enough. Having a structured, accurate form gives you a sense of control at a genuinely painful time, allowing you to move forward knowing your account has been properly recorded and your grievance formally heard.
How how to fill in ET1 form Works
The ET1 form is the official document you submit to start a claim at the Employment Tribunal. Completing it correctly is critical, because the details you provide shape the entire case that follows. Here's how the process works, step by step.
Step 1: Access the form. You can complete the ET1 online via the GOV.UK website, download a PDF, or request a paper copy. The online version is generally quicker and guides you through each section.
Step 2: Provide your personal details. Section 1 asks for your name, address, date of birth, and contact information. Accuracy here matters - the Tribunal will use these details for all correspondence.
Step 3: Identify the respondent. In Section 2, name your employer (or former employer) and provide their registered address. If you're claiming against more than one party, list each respondent separately.
Step 4: Enter your ACAS Early Conciliation number. Before submitting an ET1, you must contact ACAS. Section 2.3 requires the certificate number they issue you. Without it, your claim will be rejected.
Step 5: Describe your employment. Sections 3 to 5 cover job title, dates of employment, pay, hours, and notice period. Have your contract and payslips to hand for accuracy.
Step 6: Set out your claim. Section 8 is the heart of the form. Tick the relevant boxes (unfair dismissal, discrimination, unpaid wages, etc.) and write a clear, chronological account of what happened. Include dates, names, and specific incidents. Stick to facts.
Step 7: State the remedy sought. Section 9 lets you indicate whether you want compensation, reinstatement, or a declaration of your rights.
Step 8: Submit within the time limit. Most claims must be filed within three months less one day of the incident. Late submissions are rarely accepted.
Common Questions About how to fill in ET1 form
Do I need a solicitor to complete the ET1 form? No. The form is designed to be completed by claimants directly. That said, if your case involves complex issues like discrimination or whistleblowing, legal advice can strengthen how you present the facts in section 8.
What is the deadline for submitting my ET1? Most claims must be submitted within three months less one day from the date of the incident or dismissal. Before you file, you must first contact Acas for Early Conciliation, which can extend this window slightly. Miss the deadline and your claim will likely be rejected.
How much detail should I include in section 8.2? Enough to clearly set out what happened, when, and who was involved, but you do not need to write a witness statement. Stick to the key facts, dates, and the legal wrongs you are alleging. You can expand on evidence later in the process.
Can I amend my ET1 after submission? Yes, but you will need to apply to the tribunal for permission, and there is no guarantee it will be granted, especially if the amendment introduces new claims after the time limit has passed. It's far better to get it right first time.
What happens if I leave a section blank? The tribunal may reject your form or ask for clarification, delaying your claim. Only leave sections blank where they genuinely do not apply, and write "N/A" rather than nothing at all.
Conclusion
Filing an ET1 form is a significant step, but it doesn't have to feel overwhelming. You now know how to gather the right evidence, complete each section accurately, and submit your claim within the strict three-month-less-one-day time limit. Small details matter here. Double-check your employer's correct legal name, be precise about dates, and set out your grounds clearly so the tribunal understands exactly what happened and what you're claiming.
Remember the essentials: contact Acas first for early conciliation, keep copies of everything you submit, and don't leave your statement of claim vague or emotional. Stick to facts, chronology, and the legal basis for your case.
Your next step is straightforward. Start Acas early conciliation today through the Acas website, then draft your ET1 while the details are fresh. If your claim is complex, book a consultation with an employment solicitor before submitting.
