F10 Notification Requirements

TBT-CDM-024

Under CDM 2015, certain construction projects must be notified to the Health and Safety Executive before work begins. The F10 notification provides the HSE with key project details including the client, principal designer, principal contractor, and planned start and end dates. Failure to notify is a criminal offence. This talk explains when notification is required, who is responsible, and what information must be included.

Key Hazards
Prosecution for failing to notify a notifiable project to the HSE
Inadequate planning if project details are not formalised early
Confusion over duty holder roles when appointments are unclear
HSE intervention on site when notification has not been submitted
Control Measures
  • Notify the HSE if the project will last longer than 30 working days with more than 20 workers simultaneously.
  • Notify the HSE if the project exceeds 500 person days of construction work regardless of duration.
  • Submit the F10 notification online via the HSE website before construction work begins on site.
  • Ensure the client appoints a principal designer and principal contractor in writing before notification.
  • Include accurate start dates, estimated duration, and a brief description of the construction work.
  • Display the F10 notification in the site office where it is visible to all workers.
  • Update the F10 if key details change, such as the principal contractor or planned completion date.
  • Retain a copy of the F10 notification in the project health and safety file.
Remember
  • Notify the HSE if the project exceeds 30 working days with over 20 workers at any one time
  • Notification is also required if total construction work exceeds 500 person days
  • Submit the F10 online before construction work begins on site
  • Display the notification in the site office where all workers can see it
  • Update the F10 whenever key project details change during the works
