Your ability to obtain cheap home contents insurance is partly determined by your credit rating. Those who have excellent ratings pay far less than people who have poor ratings. What your credit rating shows is how you treat your bills and it speaks badly about you if it’s a poor one. This is a behavior that most insurance carriers believe will play out again in the way you handle your premiums. This marks you out as a bigger risk and therefore justifies a higher rate. 

So do your utmost to attend to all your bills in a timely manner. Apart from the other benefits in doing so, it will ensure you get  cheaper home insurance rates.
