Unfair Dismissal in the UK
Think you were unfairly dismissed? Understand qualifying periods, what counts as unfair dismissal, and what options may be available to you.
Last reviewed: 29 March 2026
Quick answer
Under the Employment Rights Act 1996, unfair dismissal occurs when an employer terminates your contract without a fair reason or without following a fair procedure. You generally need two years’ continuous service to bring a claim, though some exceptions apply.
What this means in practice
If you believe you have been unfairly dismissed, the first step is usually to contact ACAS for early conciliation, which is generally required before making a tribunal claim. The standard time limit for submitting a claim to the Employment Tribunal is typically three months minus one day from the effective date of termination. The ACAS early conciliation process may extend this deadline in some cases.
Common situations
Common situations include: being dismissed without any warning or process, being made redundant when you believe the real reason was unfair, your employer not following a proper disciplinary procedure, or being dismissed while on maternity leave.
What UK law says
The Employment Rights Act 1996 sets out five potentially fair reasons for dismissal: capability, conduct, redundancy, statutory illegality, or some other substantial reason. Even if a fair reason exists, the dismissal may still be unfair if the employer did not follow a fair process. The Equality Act 2010 provides additional protections against dismissal on discriminatory grounds.
What people often consider
Options people may consider include: contacting ACAS for early conciliation, submitting a claim to the Employment Tribunal, negotiating a settlement agreement with the employer, or seeking advice from a solicitor specialising in employment law. Remedies at tribunal can include reinstatement, re-engagement, or compensation.
Common mistakes to avoid
Common mistakes include: waiting too long to act (the three-month time limit is strict), not contacting ACAS first (early conciliation is mandatory in most cases), resigning before seeking advice (this may affect your claim), and not keeping records of relevant communications and events.
Frequently asked questions
Do I need two years’ service to claim unfair dismissal?
For ordinary unfair dismissal, yes — generally two years’ continuous service is required. However, no qualifying period is needed for automatically unfair dismissals such as those related to pregnancy, whistleblowing, or asserting statutory rights.
What is the time limit for an unfair dismissal claim?
The standard time limit is three months minus one day from the effective date of termination. The ACAS early conciliation process may extend this, but it is important to act promptly.
What compensation could I receive?
Compensation typically includes a basic award (calculated like statutory redundancy pay) and a compensatory award based on financial losses. The compensatory award is currently capped at the lower of one year’s gross pay or a statutory maximum.
What is ACAS early conciliation?
ACAS early conciliation is a free service where an ACAS conciliator tries to help you and your employer reach a settlement without going to tribunal. It is generally required before you can submit a tribunal claim.
