F10 Notification Requirements

• Check whether your project meets the F10 notification thresholds under CDM 2015
• Submit the F10 to HSE before the construction phase begins on site
• Include the names of the client, principal designer, and principal contractor
• Display a copy of the F10 notification in the site office for all to see
• Update the F10 if key appointments or project details change during works
• Record the date of submission and retain confirmation from HSE
• Ensure the client understands their duty to arrange notification
• Include the estimated project duration and peak number of workers
• Use the HSE electronic notification system for straightforward submission
• Brief the site team that the F10 has been submitted and is displayed on site

• DON'T start the construction phase without submitting the F10 where required
• DON'T assume notification is the principal contractor's responsibility — it is the client's
• DON'T leave the F10 unfiled — it must be visibly displayed in the site office
• DON'T ignore changes to key appointments — update the F10 with HSE promptly
• DON'T calculate thresholds incorrectly — include all workers across all trades
• DON'T forget that 500 person-days triggers notification regardless of project duration
• DON'T treat F10 notification as optional — it is a legal requirement under CDM 2015
• DON'T submit incomplete information — HSE requires accurate project details
• DON'T discard confirmation of notification — keep it in the project health and safety file
• DON'T confuse the F10 with other notifications such as asbestos or demolition notices
