FOS Car Insurance Complaints UK: Annual Data by Provider

What the FOS complaints data actually shows

The Financial Ombudsman Service is the statutory body that resolves disputes between consumers and regulated financial firms. Twice a year it releases a dataset listing every business that received a meaningful number of complaints during the period. For each named firm the data shows how many new complaints arrived, how many were resolved, and the percentage the FOS decided in favour of the consumer. That last figure is the uphold rate, and it is the single most useful number for anyone weighing up whether to escalate a motor claim dispute.

It is important to read the uphold rate carefully. It does not measure how many of a firm's customers complain, nor does it reflect the quality of its products in isolation. A high uphold rate means the FOS frequently disagreed with how the insurer handled the complaints that reached it. A low rate can mean the insurer was handling cases well at the final-response stage, or simply that the cases reaching the FOS were weaker. Volume and uphold rate read together give a fuller picture than either alone.

The dataset groups complaints into broad product categories. Motor insurance falls within general insurance, where it routinely ranks among the highest-volume lines because so many drivers hold a policy and because claims often involve disputed liability, valuations and repair quality. The FOS does not always break motor out as a standalone line in every table, so reading the underlying business-level files matters when motor is the specific concern.

Why motor insurance generates so many complaints

Motor cover produces a steady flow of disputes for structural reasons. Every claim involves a fast-moving incident, often with conflicting accounts, and the financial stakes can be high. The most common flashpoints are total-loss valuations, where the insurer's offer falls short of what the owner believes the car was worth, and liability decisions where fault is contested between two drivers.

Other recurring themes include delays in settling claims, disputes over whether a repair was carried out to an acceptable standard, and the application of policy exclusions that the policyholder did not expect. Add-on products such as guaranteed asset protection, breakdown cover and legal expenses generate their own complaints when consumers feel the cover did not deliver what was promised at the point of sale.

Premium-related complaints have grown in significance. The FCA's general insurance pricing rules, which took effect at the start of 2022, require that renewal prices for existing customers are no higher than the equivalent new-business price. Disputes about pricing, mid-term adjustments and the cost of cancelling a policy all surface in the motor complaint figures.

How to find and read the figures for a specific insurer

The complaints data is published on the FOS website as a downloadable dataset for each half-year period. To check a particular insurer, locate the relevant period, find the business by name, and read across to the general insurance line. Be aware that large insurers often trade under several brand names that may report under a single parent entity, so the figures may aggregate brands the consumer does not immediately recognise.

When comparing insurers, weigh the uphold rate against the complaint volume. A firm with a modest uphold rate but a very large book of business will naturally appear more often in absolute terms. Conversely, a smaller insurer with a high uphold rate may be handling a smaller number of cases poorly. The FOS itself cautions against reading the data as a simple league table.

For broader context, the ABI publishes industry statistics on motor claims frequency, average settlement costs and theft trends. Reading the FOS complaint picture alongside ABI claims data helps separate a firm-specific service problem from a market-wide pressure, such as rising repair costs feeding through to more valuation disputes.

The eligibility rules before the FOS will look at a motor case

A consumer cannot go straight to the FOS. The FCA's DISP rules require the complaint to be put to the insurer first. The insurer then has up to eight weeks to issue a final response. If the consumer is unhappy with that response, or if eight weeks pass without one, the case becomes eligible for the FOS.

There is a strict time limit. A complaint must usually reach the FOS within six months of the date on the final response letter, and within six years of the event complained about, or three years from when the consumer reasonably became aware of a problem. Missing these deadlines can end a case regardless of its merits, so the final-response letter should be acted on promptly.

The FOS decides cases on what is fair and reasonable in all the circumstances, taking account of law, regulation, regulators' rules and good industry practice. For motor disputes that often means scrutinising how the insurer valued a written-off vehicle, whether it relied on appropriate trade-guide data, and whether any deductions or exclusions were applied correctly.

What a successful motor complaint can achieve

Where the FOS upholds a complaint it can direct the insurer to put things right. In motor cases that commonly means increasing a total-loss valuation, paying a claim that was wrongly declined, reimbursing costs the consumer incurred because of a delay, or removing an incorrect fault marker that pushed up future premiums. The FOS can also award compensation for distress and inconvenience where the handling caused real upset.

Decisions by an ombudsman are binding on the firm if the consumer accepts them, up to the FOS award limits set out in the rules. The consumer is free to reject the decision and pursue the matter through the courts instead, which keeps their legal rights intact. Most consumers accept a favourable ombudsman decision because it is free, quicker than litigation and enforceable.

Keeping good records strengthens any motor complaint. Photographs of damage, the original policy documents, the schedule of cover, correspondence with the insurer and any independent valuation evidence all help the FOS assess whether the insurer acted fairly. The clearer the evidence trail, the easier it is for the investigator to reach a decision.

Frequently asked questions

Does the FOS publish a uphold rate for every car insurer?

The FOS publishes business-level data for firms that received enough complaints to appear in the dataset during the period. Very small insurers with few complaints may not be listed separately. The figures cover general insurance, within which motor sits, rather than always isolating motor on its own line.

What is a typical uphold rate for motor insurance complaints?

Uphold rates vary widely by firm and by period, so there is no single typical figure. The FOS publishes the actual rate for each named business, and reading several periods together gives a more reliable picture than any single snapshot.

How long do I have to take a car insurance complaint to the FOS?

Usually six months from the date of the insurer's final response letter, and within six years of the event or three years from when you became aware of the problem. Acting quickly after the final response is the safest approach.

Is there a cost to complain to the FOS about my car insurer?

No. The service is free to consumers. The insurer pays a case fee in certain circumstances, but the consumer never pays to bring or pursue a complaint.

Can the FOS force my insurer to increase a write-off valuation?

Yes. If the FOS decides the valuation was unfair, it can direct the insurer to pay more, often by reference to recognised trade-guide values and the condition of the specific vehicle. It can also add interest and compensation where appropriate.

Should I complain to my insurer first or go straight to the FOS?

You must complain to the insurer first. The FOS will only consider a case once the insurer has issued a final response or eight weeks have passed without one.
