The Security Industry Authority (SIA) introduced compulsory licensing for anyone seeking to clamp, tow away, or block vehicles on private land for a fee. Proof of the licence must be worn at all times when on duty.
Licensing is designed to protect the public by raising professional standards among those properly responsible for vehicle immobilisation. The licence requires that:
It is a condition of the licence that exemptions to immobilisation are afforded to marked emergency vehicles and those that display a valid disabled badge.
When a release fee is collected a receipt, which shows the location of the vehicle when it was immobilised, its licence number, the date of the action, and the name and signature of the person paying the fine, must be issued.
The SIA does not regulate vehicle immobilising on public roads.
