Part of our guide to What Insurance Do You Actually Need? A Plain Guide to Each Type
Insurance exists to stop a bad event becoming a catastrophe. It is not a maintenance fund, and using it as one is expensive in a way that only shows up at renewal.
Claim when the loss would genuinely hurt. For damage close to your deductible, paying yourself is often cheaper once the renewal increase is counted — and that increase usually applies for several years, not one.
The arithmetic nobody does
A claim has two costs. The visible one is the deductible. The invisible one is what your premium does afterwards.
Work it in this order:
- Estimated repair cost — get a real quote, not a guess
- Minus your deductible — that is what the insurer would actually pay
- Versus the extra premium — the annual increase multiplied by the number of years it applies
If step 2 is smaller than step 3, claiming costs you money. That is common for minor damage, because deductibles have risen while small repairs have not.
Where claiming is clearly right
Injuries, to anyone. Medical costs and liability are exactly the catastrophic risk the policy exists for, and they can run far beyond anything you would pay out of pocket.
Another party is involved. Once someone else has your details, handling it privately can go wrong badly. Their claim will find your insurer anyway.
The repair is a significant fraction of the car's value. This is the case the policy is designed for.
You genuinely cannot pay. A worse renewal price beats an unrepaired car you depend on.
Where it usually is not
Cosmetic damage on an older car. A scuffed bumper on a car you plan to keep is often not worth a multi-year premium increase.
Anything close to the deductible. If the repair is only slightly above it, the payout is small and the pricing consequence is not.
A second small claim in a short period. Frequency matters more than size to many insurers. Two small claims can affect pricing more than one large one.
Most policies require you to notify the insurer of an incident even if you do not want payment. Staying silent to protect your premium can breach the policy and jeopardise cover later. Notify, then decide about the claim separately — and get that distinction in writing from your own insurer, because wordings differ.
Raise the deductible deliberately
If you have decided you will never claim for small damage, you are paying for cover you do not intend to use. Raising the deductible lowers the premium and formalises the choice.
That only works if you actually hold the higher deductible in cash. Otherwise you have swapped a predictable cost for an unaffordable one — see how much emergency fund you need.

Frequently asked questions
Does one claim really raise my premium?
Often, yes — at-fault claims commonly affect renewal pricing for several years, and the increase applies to every renewal in that period rather than once.
What is the break-even?
Compare the payout after your deductible against the extra premium across the years the claim affects. If the payout is barely above the deductible, claiming frequently loses money.
Should I report an accident even if I do not claim?
Reporting and claiming are different. Policies usually require notification of an incident; that is not the same as asking for payment. Check your own wording.
Does a no-fault claim still count?
It can. Some insurers price on claim frequency regardless of fault, which is why comprehensive claims for glass or theft are treated differently by different companies.
