Can Credit Score Determine Home Insurance Rates?
In most states, yes. Insurers use credit-based insurance scores to help set rates, though a few states ban the practice entirely.

Why your renewal went up with no claim and nothing changed
If you didn't file a claim and nothing changed on the house, your credit-based insurance score is a likely reason the number moved. Insurers recheck this score at renewal, and even small shifts in your credit file, like a higher card balance or a new inquiry, can nudge the score down and the price up. Your declarations page won't spell this out, but the insurer's rating factors usually include it unless you're in a state that bans the practice. You can't argue the fairness of it into a lower price, but you can ask what the score was based on, check your credit report for errors, and compare how other insurers weigh it. Some weigh credit less heavily than others.
Insurers don't all weigh credit the same way
One insurer's rating system can punish a dip in your credit score more than another's. Getting quotes shows whether a different insurer would charge you less for the same house, same coverage, same score.
What makes up a credit-based insurance score
A credit-based insurance score isn't the same number a lender sees when you apply for a car loan or a credit card. It's built from your credit file but weighted for insurance risk, using things like how long you've had credit, how much of your available credit you're using, whether payments are on time, and how much new credit you've opened recently. A collections account or a maxed-out card affects this score even if you've never missed an insurance payment in your life.
Each insurer builds or buys its own version of this scoring model, so the same credit file can produce different scores at different companies. One insurer's model might weigh a recent hard inquiry heavily. Another might barely count it. This is part of why two insurers can look at the same house and the same homeowner and land on two different prices, even before you factor in anything else about the property.
The states that restrict or ban credit-based scoring do it differently. Some ban the practice outright. Others allow it but limit how much it can affect the price, or require insurers to prove the correlation between credit and claims in their state. Whether any of this applies to you depends on where you live. It's worth checking your state's insurance department site if you want the specifics rather than assuming your state works like a neighbor's.
You're entitled to a free credit report from each of the three bureaus once a year, separate from any monitoring service tied to a credit card. Errors are common enough to be worth checking. An account that isn't yours, a balance reported wrong, a paid-off loan still showing as open, any of these can drag the score down. Fixing an error won't necessarily lower your home insurance price right away, since insurers pull their own snapshot at renewal. It does close the gap between what your credit file says and what it should say before the next one.
Can you raise your credit-based insurance score before the next renewal
There's no quick fix for a credit-based insurance score, the same way there's no quick fix for a credit score generally. The things that move it are the things that move any score built from your credit file. Paying on time matters. So does keeping card balances low relative to their limits, and not opening a string of new accounts in a short window. None of that changes in a month. Most of it takes a full billing cycle or more to even show up on your credit report, and then more time before it works its way into a new score.
What you can do before renewal is make sure nothing is actively working against you. Pay down a card that's close to its limit if you can. Don't apply for new credit, a store card or a car loan, in the months leading up to your renewal date, since a hard inquiry can ding the score. Keep older accounts open rather than closing them, since the length of your credit history is part of what gets weighed. None of this guarantees a lower score, but it removes the things most likely to push it down further.
Some states require insurers to let you request an exception if your credit was affected by something outside your control, like a medical collection, identity theft, divorce, or the death of a spouse. Not every state has this rule, and the ones that do define a qualifying event differently. If one of these applies to your situation, it's worth asking the insurer directly what documentation they need rather than assuming it will be factored in automatically.
Timing matters more than most people expect. Insurers pull your credit-based score at specific points, usually at renewal, not continuously throughout the year. Improving your credit the week before renewal may not help if the insurer already pulled the score weeks earlier for processing. If you know your renewal date, working on your credit three to six months ahead gives any improvement time to show up in your file and be reflected in the next pull.
Before your next renewal
Check your renewal date, then pull your free credit report now. Fix anything wrong with time to spare, and get a few quotes before that date to see whether another insurer prices your score the same way.
