Lock your windows as well as your doors, and secure any outbuildings, sheds and garages. Don’t leave anything unlocked as some insurance providers might only pay out for a burglary claim on an unoccupied home if there are signs of forced entry.
Keep tools locked away so they can’t be used to break into your house. And if you have no option but to leave a ladder outside, ensure it’s secured to a permanent fixture with a padlock and chain.
Don’t leave spare keys outside under plant pots or large stones. You may think your hiding place is original, but a determined thief will almost certainly find them.
