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 holding company income statement totalled €258 million in 2025 (2024: €196 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 2,332 at year-end 2025 (2024: 1,924). 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.
