Van owners are also advised to register their tools for free at Immobilise taking note of the serial numbers and models, and to use ultraviolet pen to (invisibly) mark their property, which increases the chances of having them returned to you in the event of being lost or stolen.

Van drivers should also consider the following measures to reduce the risk of being a victim of crime:

• Always lock all doors and shut windows, physically checking van doors are locked.

• Park in a garage or secure area where possible.

• Park with the doors against a wall.

• If you park on your driveway consider installing motion activated CCTV.

• Be particularly aware when unloading.

• Remove tools from the van if possible.

• To increase the security of tools, you can bolt either a cage or box to the base of the van which should be secured with a sturdy close shackle padlock to reduce and deter further incidents.

• Setting an alarm or immobiliser will make it more difficult for the offender.

• Consider upgrading locks/fitting additional protection.
