Via web Portal

You can submit your objection straight to Hertsmere Council via their own web portal.

Before you do, we strongly suggest you tackle it with the help of this guide.


As you probably know, government bureaucracy can be a headache and this form looks seriously off putting. Remember: nothing worth having comes easy, but this guide may make it slightly easier.
