Property marking

For advice on property marking, use our A-Z of crime prevention here.

Property marking can protect your belongings against theft and can help the police return your property to you if recovered. Marking also makes it less attractive to steal, as it creates a bigger risk for thieves if they are caught in possession.

However you choose to mark your property, you should show that you have taken crime prevention measures and always use stickers if provided. Inform your insurance company as you may get a discount.
