How It Works

Statutory notice periods in the UK are based on length of continuous service. Employees who have worked for at least one month but less than two years are entitled to one week's notice. After two years, entitlement increases by one week for each complete year of service, up to a maximum of 12 weeks' notice after 12 or more years.

Your contract may specify a longer notice period than the statutory minimum — the longer period always applies. Many professional roles specify one to three months' contractual notice. During the notice period, employees retain all normal employment rights including pay, holiday accrual and benefits.

This calculator determines both the statutory and contractual notice period based on your length of service and contract terms. It also calculates your pay during the notice period and shows the earliest date employment can end. Payment in lieu of notice (PILON) is also covered where your contract allows it.

Example: 5 years' service, 1-month contractual notice

  1. Statutory notice: 5 weeks (1 week per year of service)
  2. Contractual notice: 4.3 weeks (1 month)
  3. Applicable notice: 5 weeks (statutory is longer)
  4. Notice pay at £35,000 salary: 5 × £673.08 = £3,365.38
  5. Earliest end date: 5 weeks from resignation/dismissal
