Statutory minimum

The legal floor

GOV.UK says the statutory redundancy notice periods are at least 1 week if employed between 1 month and 2 years, 1 week for each year if employed between 2 and 12 years, and 12 weeks if employed for 12 years or more.

Contractual notice

Your contract can improve on it

GOV.UK also says an employer can give more than the statutory minimum in the contract, but cannot give less. That is why the calculator compares the statutory minimum against any longer contractual notice you enter.

Notice pay

How pay is described in the official guidance

GOV.UK says notice pay is based on the average earned per week over the 12 weeks before the notice period starts. During redundancy, your employer should either pay you through your notice period or pay in lieu of notice depending on the circumstances.

Acas practical point

Ask for the key details clearly

Acas says it is a good idea to ask for the length of the notice period, the start date, whether you can leave early, and how unused holiday or benefits will be handled. That makes this a very practical follow-up guide rather than a generic legal article.

Important: This guide is intentionally narrow. Misconduct dismissals, garden leave, payment in lieu of notice, settlement terms, and other facts can change the practical outcome.
