How much does home insurance go up after a claim?
There's no fixed figure — it varies a lot by insurer, the size and type of claim, and your claims history. A water damage claim can raise your renewal premium and, on some policies, reduce your no-claims discount. Anyone quoting a single guaranteed percentage is guessing.
There is no set amount, and be wary of anyone who quotes you a precise percentage — it genuinely varies from insurer to insurer and claim to claim. Premiums are priced on risk, so what happens to yours depends on the size of the claim, the cause, how many claims you've made before, and each insurer's own view of that risk.
As a rule of thumb, a larger claim tends to have more effect than a small one, and a pattern of repeated claims usually matters more than a single one-off. Some causes of water damage — like recurring leaks or damp — can concern insurers more than a one-time accidental escape of water, because they suggest an ongoing problem.
A claim may also affect your no-claims discount, which is the reduction some insurers give for each year you don't claim. On buildings and contents policies this works differently from car insurance, and not all policies offer it, so check your wording. Losing it can add to the cost at renewal on top of any risk-based increase.
It's worth remembering the increase applies to future premiums, not the payout itself — you don't repay the claim, but you may pay more going forward. That's why, for smaller damage, it's sensible to weigh the likely renewal impact against the excess before claiming.
This is general information rather than financial advice, and we can't tell you what your specific insurer will do. When your renewal arrives, it's always worth shopping around — a claim on your record doesn't stop other insurers quoting, and prices vary widely.
