Great Britain Statutory Redundancy Notice Pay methodology

grossNoticePay = noticeWeeks × averageWeeklyPay

noticeWeeks = service under 1 month ? 0 : service under 2 years ? 1 : min(12, floor(continuousServiceMonths ÷ 12))

averageWeeklyPay = entered averageWeeklyPay

Money inputs and outputs use GBP. Pay, time, benefits and work-related costs use the units stated beside each input.

• The worked example uses the same shared-work-logic engine as the interactive planner.
• Unsupported eligibility, policy branches and out-of-range assumptions fail closed.
• Result cards, trace, CSV, PDF and methodology bind to named engine result fields.

• Great Britain jurisdiction and statutory redundancy-dismissal coverage are confirmed.
• The entered average weekly pay is the correct twelve-week average.

Official dependencies used by this calculator are captured in the Wage101 evidence register and version-acknowledged in this page history. User-entered work and pay assumptions remain separate from those official inputs.

• Northern Ireland, resignation and contractual notice exceeding the statutory minimum are excluded.
• PILON/PENP tax treatment, sickness or leave adjustments, bonuses, commission and non-cash benefits are excluded.

This is educational decision support, not personalised tax, legal, financial or career advice. Check how the rules that apply in United Kingdom treat your work and pay circumstances, and seek qualified advice where appropriate.

Registered family-level suites test formula invariants and example reconciliation; the release ledger records that coverage without claiming a separate oracle for every line of public copy. Registered official sources block dependent public workflows when their evidence or version acknowledgement is unavailable or invalid. Work and pay inputs remain user-supplied because they vary by person, job and contract.
