The employee benefit expense item mainly concerns the costs of group-wide activities at holding company level.

Nearly all the personnel are on the Alliander N.V. payroll. Employee benefit expenses are charged to the organisational units where these employees work. Employee benefit expenses in the income statement totalled €196 million in 2024 (2023: €163 million), and relate to employees working in the Alliander N.V. corporate staff departments and service units.

The number of employees, based on a 38-hour week (FTEs), was 1,924 at year-end 2024 (2023: 1,563). The proportion of costs attributable to the direct deployment of Alliander staff on projects at other organisational units has been deducted from Alliander’s employee benefit expenses.
