Probation is contractual. Statutory rights such as notice and unlawful discrimination protection apply from day one.

How to use this calculator

  1. Enter the first day of your employment.
  2. Choose a standard probation length or enter your own in months.
  3. Use the suggested review date to prepare for your end-of-probation meeting.

How the calculation works

  • The probation length in months is added to the start date and one day is subtracted, so the end date is the last day of probation.
  • The suggested review week is the working day roughly one week before probation ends.

Things to keep in mind

  • Probation is a contractual arrangement — it does not change most statutory employment rights.
  • Notice during probation is often shorter, but it cannot be less than the statutory minimum once that applies.

Frequently asked questions

Can my probation be extended?

Yes, if your contract allows it. Employers usually have to tell you before the original end date and confirm the extension in writing.

Do I have rights during probation?

Yes. Statutory rights such as minimum wage, holiday accrual and protection from discrimination apply from day one.

What notice applies during probation?

Whatever your contract states, subject to the statutory minimum of one week once you have worked a month or more.
