In accordance with Article 10(13) and Article 10(14) of Directive (EU) 2016/798, the single safety certificate must be updated when a railway undertaking substantially changes the type or scope of its operation or extends its area of operation. The keeper of a single safety certificate shall immediately inform the safety certification body when proposing such changes, which may be technical, operational or organisational

An updated safety certificate may be required in the event of substantial changes to the safety legislative framework in accordance with Article 10(15) of Directive (EU) 2016/798.

The renewal of the single safety certificate is required for railway undertakings that already have a single safety certificate and wish to continue their activities of rail transport after the expiry of their current single safety certificate.

The renewal or extension of the single safety certificate shall be based on an application from the railway undertaking.

When applying for an update or renewal, the railway undertaking must hold a valid single safety certificate (or a valid Part A certificate and a valid Part B safety certificate) for the area of operation to be covered by the single safety certificate.
