If the deceased has left a property which is now unoccupied (empty houses) then the executors must make sure it is made secure along with the contents and protected from theft, vandalism and other hazards.
During the cold months it will often be sensible to drain down the water system unless the central heating system is being kept on.
Basic precautions such as security lights, timers for switching lights or lamps on and off and arranging for milk and newspaper deliveries to be stopped can easily be implemented. Telling the neighbours who the keyholder is should also be considered. Executors should consider removing valuable items and arranging secure storage elsewhere, especially in light of insurance cover for contents on empty property usually being very restricted.
