F10 notification

An F10 is the notification a client, or their representative, must send to the HSE for construction projects that are notifiable under CDM 2015. A project is notifiable if the construction work is scheduled to last longer than 30 working days and have more than 20 workers on site at any one time, or to exceed 500 person-days.

The F10 records basic details of the project and its duty holders. Submitting it is the client’s duty, and it must be done before the construction phase begins.
