Lots of factors affect your home insurance premium. The area in which you live, the size of your property and your individual circumstances all have a bearing.
If you have a good level of home security, such as intruder alarms and approved window and door locks, you are going to be able to qualify for a good level of discount. Also having smoke alarms can help reduce premiums.
Another factor is increasing your voluntary excess. When considering this option, make sure that the amount of excess you opt for can be met by you in the event of a claim.
