How much notice must I give my employer?

After one month but less than two years, you must give at least one week. After two years, you must give one week per full year worked, up to 12 weeks maximum.

Can my contract ask for more than the statutory minimum?

Yes. Contracts often specify longer notice periods, especially for senior roles. You must honour your contract unless you negotiate otherwise.

Is notice the same during probation?

Probation clauses sometimes shorten notice. Check your contract; statutory rules still set floors in many cases.

Does this calculator cover redundancy notice from the employer?

No. Employer notice periods follow different statutory scales. Use government guidance or legal advice for dismissal scenarios.

1 month notice period calculator UK — is that statutory?

One calendar month is a common contractual notice, not the statutory floor. Statutory employee notice is measured in weeks based on service. If your contract says one month, that usually overrides the shorter statutory minimum.

4 weeks notice period calculator UK?

Four weeks equals the statutory minimum after four complete years of continuous service (one week per year), unless your contract requires longer.

How do I calculate notice from the 15th of the month?

Count clear calendar days or working days as your contract defines. Statutory guidance is week-based; for a mid-month resignation date, state an explicit last working day in writing to avoid ambiguity.

Employee notice (minimum)

1 month vs 4 weeks vs statutory weeks

Searchers often need scenario answers, not a generic “notice period calculator”:

Under 2 years: statutory floor is usually 1 week (after 1 month’s service).
4 years’ service: statutory employee notice ≈ 4 weeks.
“1 month notice” in the contract: honour the contract even if statutory weeks are shorter.

Always put the resignation and last day in writing.
