| ★ TL;DR TL;DR: A road traffic accident affects your motor insurance in multiple ways: immediate notification duty to your insurer under FCA ICOBS, no-claims discount impact at renewal, premium loading for up to five years in claims history, and the distinction between at-fault and no-fault outcomes. The ABI Q4 2025 average premium is £622. Understanding how insurers treat post-accident history is essential for managing renewal costs and securing cover with a claims record. |

Your immediate notification obligation after an accident
The FCA's ICOBS rules and the terms of virtually every UK motor insurance policy require the policyholder to notify their insurer of any road traffic incident promptly, typically within 24 hours or as soon as reasonably practicable. This obligation applies regardless of: whether you were at fault; whether you intend to make a claim under your own policy; whether the other party is pursuing a claim against you; or whether the damage appears minor.
Failure to notify within the required period can constitute a breach of policy conditions and may affect your policy's validity at claim time, including for subsequent, unrelated incidents during the same policy year. When notifying, provide your account of events factually; supply all details of the other party and witnesses; and ask the insurer to record on the claim file whether you consider the incident no-fault.
Under the Consumer Insurance (Disclosure and Representations) Act 2012 (CIDRA), you must declare all claims and incidents accurately at any subsequent renewal or new policy application. Omitting an incident from your claims history, even one where no claim was made under your own policy, is a material non-disclosure if an insurer asks about incidents in the relevant period.
How at-fault versus no-fault outcome affects your NCD
The no-claims discount (NCD) is the primary mechanism through which a clean driving history reduces UK motor insurance premiums. NCD is measured in years, each claim-free year adds one NCD year. Most UK insurers apply their NCD scale such that five or more claim-free years produces a discount of 60 to 75 percent on the base premium.
An at-fault claim, where you are determined to be wholly or partially at fault for the incident, typically results in the loss of two NCD years at renewal. A five-year NCD reduces to three years; a four-year NCD reduces to two years. The specific step-back depends on the insurer and product.
A no-fault claim, where another driver's insurer accepts full liability and recovers all costs, should not affect your NCD, because NCD reflects fault claims. However, some insurers apply a "non-fault claim notation" to the policy that may affect renewal underwriting even without NCD reduction. Confirm with your insurer in writing that a no-fault outcome will preserve your NCD before assuming it is protected.
NCD protection is a paid add-on available on most Comprehensive policies. Where NCD protection is in force, a specified number of fault claims per policy year (typically one) does not reduce the NCD at renewal. NCD protection does not prevent the insurer from applying a loading to the base premium at renewal to reflect the increased risk evidenced by the claim.
Premium impact at renewal: the five-year claim history window
UK motor insurance underwriters assess a five-year claims history as part of the renewal and new policy quotation process. A fault claim entered on the claims history remains a disclosed claim for five years from the incident date, affecting premiums across that entire period regardless of how many clean years follow.
The premium impact of a fault claim in the history is not fixed, it varies by: the claim's severity (a £500 windscreen repair has a smaller impact than a £25,000 injury and vehicle total-loss); whether the policyholder switches insurer (each new insurer re-rates on the full disclosed history); and the policyholder's accumulated NCD remaining after the step-back.
For typical at-fault collision claims, the premium loading in the first renewal year after a claim is frequently 30 to 60 percent above what the premium would have been without the claim. This loading typically declines over subsequent years as the claim ages and the NCD accumulates again from the post-claim lower base.
Shopping around after a claim: the open market approach
Following an accident, the instinct to remain with the existing insurer for simplicity is understandable but may not be financially optimal. The FCA's General Insurance Pricing Practices rules (PS21/5, January 2022) require renewal prices to not exceed equivalent new-customer prices. However, the "equivalent new-customer price" for a policyholder with a recent fault claim is higher than it was pre-claim. Shopping the open market at renewal remains important even post-claim.
Different insurers weight claims history differently in their actuarial models. Some underwriters apply heavier loadings on recent fault claims; others are more accommodating of a single claim with a long surrounding claim-free period. Running a full market comparison at renewal, rather than accepting the incumbent renewal price, typically identifies meaningful price differences for post-claim profiles.
For drivers with multiple claims in five years, mainstream direct brands may decline to quote or apply disproportionate loadings. A BIBA-registered specialist broker (biba.org.uk/find-insurance/) can access underwriters with specific appetite for adverse-history profiles at more competitive terms than standard direct channels.
Common myths about car insurance after an accident
Myth: If I don't claim on my own policy, I don't need to tell my insurer. False. The notification obligation applies to all incidents. Failure to notify can breach policy conditions; the incident must also be declared on future applications and renewals.
Myth: A no-fault claim never affects my premium. Partially false. A successful no-fault outcome should preserve NCD. However, some insurers apply a non-fault claim notation that may influence renewal pricing. Confirm with your insurer in writing.
Myth: Paying the repair bill privately avoids insurance consequences. Partially true only in very limited circumstances. If the other party later makes a claim against you for injuries or subsequent damage, your insurer needs to be notified to manage that liability claim. A repair paid privately that involves undisclosed unreported injuries is particularly risky.

Frequently Asked Questions
Does a no-fault accident affect my car insurance premium?
A genuine no-fault outcome, where the at-fault party's insurer accepts liability and recovers all costs, should not reduce your NCD. However, some insurers apply a non-fault claim notation that may influence renewal underwriting. Confirm with your insurer in writing that no-fault status will preserve your NCD and not trigger a base premium loading.
How long does an accident stay on my insurance record?
Claims and incidents must be declared for the period specified by each insurer when asked, typically five years from the date of the incident. After five years, the incident no longer needs to be disclosed to most insurers. Confirm the specific disclosure period required by each insurer at quotation.
Should I tell my insurer about an accident even if I'm not claiming?
Yes. Most motor policies require notification of any incident within 24 hours or as soon as practicable. Failure to notify can breach policy conditions. The incident must also be disclosed at future renewals and new policy applications under CIDRA 2012.
How much will my premium increase after an at-fault accident?
Premium increases after a fault claim depend on: the severity of the claim; the residual NCD after the step-back; the specific insurer's rating model; and open-market competition. Typical first-year increases range from 30 to 60 percent above the pre-claim equivalent premium. Running a full market comparison at renewal identifies the most competitive post-claim price.
Can I get car insurance if I have had multiple accidents?
Yes, though mainstream direct brands may decline or apply disproportionate loadings for multiple claims in five years. A BIBA-registered specialist broker (biba.org.uk/find-insurance/) accesses underwriters with specific appetite for adverse-history profiles at more competitive terms.
