Does Credit Score Affect Car Insurance UK 2026

Last reviewed: 26 April 2026

UK versus US: why credit scores are not used in UK motor underwriting

In the United States, credit scores, particularly the FICO score, are used by motor insurers as an actuarial rating factor in most states. US research has shown a statistical correlation between credit score and motor insurance claim frequency, and US insurers are broadly permitted to use this correlation in pricing.

In the UK, this practice does not apply to the motor insurance underwriting model. The Financial Conduct Authority's regulatory framework for general insurance, the ICOBS sourcebook, requires that premiums reflect actuarial risk factors that are relevant, accurate, and non-discriminatory under the Equality Act 2010. Credit score as a direct motor insurance underwriting factor has not been adopted by UK FCA-authorised motor insurers because: (a) the UK actuarial evidence on the correlation between credit history and motor claims is weaker than the US evidence; and (b) the FCA's consumer protection framework creates regulatory concern about the discriminatory potential of credit-based pricing.

If you have a poor credit score, due to missed payments, defaults, or other credit history events, this does not directly affect the premium that a UK motor insurer charges you for your Comprehensive, TPFT, or TPO motor insurance. The ABI's 2025 published statement on motor insurance underwriting factors confirms that the standard UK motor actuarial model uses: age, occupation, postcode, vehicle type and group, annual mileage, use class, claims history, driving convictions, and no-claims discount. Credit score is not listed.

The soft credit check for monthly payments: what actually happens

When you apply to pay your motor insurance premium in monthly instalments rather than as an annual lump sum, the insurer or the premium finance company arranging the instalment credit agreement performs a credit assessment. This is governed by the FCA's Consumer Credit sourcebook (CONC) and the Consumer Credit Act 1974.

A soft credit inquiry, sometimes called a soft pull or soft check, is performed to assess your creditworthiness for the instalment credit agreement. This is similar to the soft checks performed when you compare financial products or when employers conduct background checks. A soft credit check does not appear on your credit file as a credit application and does not affect your credit score. It is visible only to you when you view your own credit file, not to other lenders.

The soft check assesses whether the applicant is likely to be able to meet the monthly instalment commitments. Where the soft check indicates significant affordability concerns, existing defaults, insolvency proceedings, or CIFAS fraud markers, the premium finance company may decline to provide the instalment credit arrangement, though the underlying annual insurance policy may still be available on an annual payment basis.

CIFAS: the fraud database that does affect insurance

The Credit Industry Fraud Avoidance System (CIFAS) is a fraud prevention database separate from credit reference agencies. CIFAS records fraud-related events, confirmed fraudulent insurance claims, application fraud, account takeover, and similar events, and is accessed by financial services providers including insurance companies.

A CIFAS fraud marker on an individual's record is a direct signal to insurers that the individual has been involved in fraud, either as a perpetrator or, in some cases, as a victim. Unlike credit score, a CIFAS marker is directly relevant to insurance underwriting because insurance fraud is a specific risk that insurers are entitled to price and manage.

Where a CIFAS marker exists, from a previous insurance fraud event, for example, a motor insurer may: decline the application; apply a significant premium loading; or require additional verification before providing cover. The distinction from credit score is important: CIFAS is a fraud-prevention tool, not a creditworthiness assessment, and insurance fraud risk is a legitimate underwriting consideration.

Experian, Equifax, and TransUnion: their role in UK motor insurance

The three main UK credit reference agencies, Experian, Equifax, and TransUnion, hold credit histories for UK consumers. For UK motor insurance underwriting (as opposed to monthly payment finance), their credit data is not accessed by FCA-authorised motor insurers for premium calculation purposes.

Their data is accessed in two specific limited contexts: the soft check for monthly instalment affordability (described above); and in fraud prevention and identity verification processes, where matching the policyholder's identity against CRA data helps confirm identity and detect synthetic identity fraud.

What actually drives your UK motor insurance premium

The factors that FCA-authorised UK motor insurers use in underwriting are specific to the motor risk and are unrelated to general creditworthiness. The ABI's 2025 motor insurance market data confirms the primary actuarial rating factors: age (the single largest factor for under-25 drivers); Thatcham insurance group of the vehicle; postcode; annual mileage; use class (SDP, commuting, or business); claims history and NCD level; driving convictions; and named driver profiles.

These factors collectively produce the actuarially-assessed premium. Improving your motor insurance premium requires addressing these factors, not improving your credit score.

Key Figures

What you can do to improve your motor insurance premium

Since UK motor underwriting does not use credit scores, improving your credit score has no direct effect on your motor insurance premium. The factors that do affect your premium, and that you can legitimately influence, are: accumulating no-claims discount over time (the most powerful premium-reduction tool); choosing a vehicle in a lower Thatcham insurance group; accurately declaring lower annual mileage if genuinely reduced; overnight storage in a garage or secured driveway rather than on a public road; and where applicable, telematics products that reward safe driving behaviour with lower renewal premiums.

BIBA-registered specialist brokers (biba.org.uk/find-insurance/) can assess whether your risk profile is best served by a mainstream direct brand or by specialist underwriters, particularly for any driver with an adverse history or a non-standard vehicle. Confirm broker FCA authorisation at register.fca.org.uk. Insurance Premium Tax at 12 percent (HMRC, gov.uk) applies to all UK motor insurance premiums regardless of payment method. The Road Traffic Act 1988, section 143 minimum applies regardless of credit history.

Frequently Asked Questions

Does my credit score affect my car insurance premium in the UK?

No. UK motor insurers do not use credit scores as an actuarial underwriting factor for setting premiums. This is different from the US, where credit score is commonly used. UK motor premiums are based on age, vehicle, postcode, mileage, claims history, and driving convictions.

Will applying for car insurance affect my credit score?

Getting a motor insurance quote does not affect your credit score. If you apply to pay monthly, a soft credit check may be performed for the instalment credit arrangement. Soft credit checks do not affect your credit score and are not visible to other lenders.

What is CIFAS and how does it affect car insurance?

CIFAS is a fraud prevention database that records confirmed fraud events. A CIFAS marker, from a previous insurance fraud, for example, can affect your ability to obtain motor insurance or the premium you are charged, because insurance fraud risk is a legitimate underwriting consideration for insurers.

Can I be refused car insurance because of my credit history?

Not typically for the insurance itself, UK motor insurance underwriting does not use credit history. However, the monthly instalment credit arrangement may be declined based on affordability assessment. The annual insurance policy itself remains available on an annual payment basis regardless of credit history.

What factors do UK motor insurers actually use to set premiums?

UK motor actuarial rating factors confirmed by the ABI include: age, Thatcham vehicle group, postcode, annual mileage, use class, claims history, no-claims discount level, driving convictions, and named driver profiles. Credit score is not a factor in UK motor underwriting.
