How to apply for British labor arbitration? Don’t miss the 3-month deadline
When working in the UK, the biggest fear is not working overtime, but HR calling you into a small conference room one day and telling you to leave "because of the company's restructuring." The first reaction of many Chinese people is to admit that they are unlucky and quickly find another job - but you may not know that if this dismissal is illegal, you actually have the right to sue the company to the Labor Arbitration Tribunal (Employment Tribunal) , and you will not be charged a penny to apply for .
The difficulty is that this road has an "invisible gate" - a time limit. If you miss it, no matter how good the reason is, the court will not accept it. Today I will explain the rules for 2026 once and for all. ⏳
What can UK labor arbitration sue? Not just "being fired"
The Employment Tribunal deals with legal disputes between employees and employers. There are several common types:
▪️ Unfair Dismissal - The company fires you without justifiable reasons or without following due procedures;
▪️ Discrimination (Discrimination) - Unfair treatment due to race, gender, age, religion, pregnancy, etc.;
▪️ Wage deduction (Unlawful) Deduction) ——Not paying the money that should be paid, not giving overtime pay and vacation money;
▪️ Breach of contract, unequal pay for equal work, etc.
The key difference: currently you need 2 years of service to file a complaint for "unfair dismissal", but you are eligible to file a complaint for "discrimination" and "deduction of wages" on the first day you join the company, and there is no seniority threshold. Chinese people often ignore this point - even if you are fired just three months after joining the job, as long as the dismissal is discriminatory, you can still sue.
The first step in applying for labor arbitration: the unavoidable ACAS mediation
Many people think that just filling out the form and submitting it to the court is enough – that’s not true. Before submitting an arbitration application, you must first contact ACAS for "Early Conciliation" . This is a legally mandatory step. If you skip it, your application will be returned directly.
ACAS is the UK’s official free mediation agency. After you submit your notice online, a mediator will contact you and your employer to see if you can negotiate a settlement without going to court. If the negotiation is successful, you can save time and effort and you can get compensation; if the negotiation is not successful, ACAS will issue you an conciliation certificate (EC Certificate) , and you can use this number to formally apply for arbitration.
A new change for 2026 to keep in mind: from December 1, 2025, the ACAS mediation period will be extended from 6 weeks to a maximum of 12 weeks. The advantage is that both parties have more time to talk; but for you, it also means not waiting until the last minute to find ACAS.
Labor arbitration time limit: 3 months minus 1 day, this is the iron rule
This is the most critical point of the whole article. The time limit for most labor arbitration applications is - 3 months minus 1 day from the date of the incident. For example, if you are fired on June 10th, the deadline is September 9th. After this day, the court will generally no longer accept the case unless there are very special reasons.
Fortunately, contacting ACAS will "stop the clock" : The period from when you notify ACAS to when you get the mediation certificate is not included in the 3 months and will be made up afterwards. But don't mistake "suspension" for "indefinite extension" - the safe way is to contact ACAS as soon as possible after is fired, preferably within the first month, to give yourself enough margin.
📌 Policy Outlook: According to the "Employment Rights Act 2025", the time limit for most arbitrations is expected to be extended from to 6 months from October 2026. But before it officially takes effect, please always operate according to "3 months minus 1 day" and don't bet on the new rules.
Does it cost to apply for labor arbitration? How much can you pay?
Good news: Submitting an application for arbitration (ET1 form) and attending court are free. The British Supreme Court ruled that the fees were illegal as early as 2017, and has maintained zero fees since then. The only thing you have to pay is usually the money for a lawyer, but in many cases of discrimination or wage arrears, you can first negotiate a "contingency fee" or use union/legal aid.
In terms of compensation, taking unfair dismissal as an example, it is divided into two parts: Basic Award (Basic Award) is calculated based on length of service, with a maximum limit of approximately £22,530 from April 2026; Compensatory Award (Compensatory Award) covers your actual economic losses, with a maximum limit of approximately £123,543 or 52 weeks’ salary, whichever is lower. There is no cap on compensation in discrimination cases, and mental damages (Vento bands) may also be added.
Looking further forward, starting from January 2027, the upper limit of compensatory damages for unfair dismissal will be lifted by and replaced by full compensation based on actual losses - a major benefit to employees who have been wrongfully dismissed.
Practical advice: 3 things to do on the day you get fired
1️⃣ Leave evidence : Save all screenshots of dismissal letters, emails, WeChat/Teams chats, pay stubs, and schedules, especially records involving discriminatory remarks;
2️⃣ Remember the dead time : Write "incident date + 3 months minus 1 day" into the mobile calendar, and set a two-week advance reminder;
3️⃣ Contact ACAS as early as possible And consult a lawyer : Any mistake in procedural details (such as which day is considered the "date of incident" and whether to appeal internally first) may affect the outcome.
There is another layer that Chinese visa holders should pay attention to: labor disputes may involve Right to Work and visa continuity, and improper handling may affect subsequent visa renewal or even permanent residence applications.
