You must usually submit your claim within 3 months less 1 day of your dismissal date. Based on the date entered, your approximate deadline is 31 March 2026. ACAS early conciliation is required first and can affect the deadline.

ACAS early conciliation

Before you can go to tribunal, you must contact ACAS for early conciliation. This is free and often resolves claims without a hearing. ACAS: 0300 123 1100.

What is unfair dismissal?

Unfair dismissal occurs when an employer dismisses an employee without a fair reason or without following a fair process. Potentially fair reasons include conduct, capability, redundancy, statutory restriction, or some other substantial reason.

How much compensation can I get?

Compensation has a basic award, calculated like redundancy pay, and a compensatory award for actual financial loss. The compensatory award is capped at the lower of the statutory limit or 52 weeks gross pay.

What is the Polkey reduction?

A Polkey reduction can apply where the employer used a flawed process but a fair process may still have led to dismissal. The tribunal can reduce compensation to reflect that chance.

What does this mean?

This calculator is designed to help you understand the likely number before you make a decision or start an application.

Your result should be checked against official UK guidance, especially if your circumstances include dependants, exemptions, prior leave, or a complex immigration history.

Treat the figure as a planning tool rather than legal advice. Where the answer affects an application deadline or major payment, speak to an authorised adviser.
