Frequently asked questions about F10 Notification

Do I need an F10 for a house extension?
Only if the project exceeds the thresholds: more than 30 working days with more than 20 workers at any point, or more than 500 person-days total. Most domestic extensions don't reach these thresholds.
When must the F10 be submitted?
The F10 must be submitted to the HSE as soon as practicable before the construction phase begins. It should be submitted by the client (or their agent) and include details of the principal designer and principal contractor.
