NS&I Workforce Management Data on Staff Numbers and Paybill Costs

Monthly management information on staff numbers and paybill costs for National Savings and Investments (NS&I). The data includes payroll and non-payroll staff split by full-time equivalents and headcount, with payroll costs broken into salaries, allowances, and pension contributions.

Use Cases

• Model payroll expenditure based on component parts like salaries and pension contributions.
• Compare the use and cost of contingent labor versus permanent staff based on non-payroll data splits.
