First and foremost, make sure that you are setting your home alarm from INHOMESECURITY.com before you leave your house. This is simply because criminals tend to get more desperate for the essentials during colder and more drastic months.
Second, make sure that your family has the appropriate clothing for this type of weather. For example, your children should not be leaving the house dressed in anything less than a heavy duty winter coat, appropriate pants, thick shoes and warm headwear. This will keep them optimally warm and safe. Even though this is extremely important for children, it's also important for you and other adults in the family as well.
Additionally, make sure that you're going to have the extra funds available to finance the increased electric bill. Having a heated home all winter long will surely increase your electric bill, and if you're not exactly prepared for more financial stress, this could be a problem. Be prepared financially to take care of the increased costs for heating as well as extra supplies in case of an emergency.
