Before you leave your property in the care of a house sitter check with your insurance company if there will be any changes to your premium for cover provided in the period that you're away. It is widely agreed that an occupied property is far more secure than an empty one, so your insurance provider should charge no penalty for the arrangement. In fact, the converse is often the case: many insurance providers say you cannot make a claim on your home and contents policy if the problem occurred after your property had been empty for more than 30-60 consecutive days. (The actual number of days varies between policies.)
