A cheap premium can look like a clear win until you need to make a claim, change a policy or get a straightforward answer from customer services. That is where insurer complaint data can be useful. It gives you a window into the problems real customers report, helping you look beyond price before you commit.
Complaint figures should not be treated as a league table with one automatic winner. A large insurer serving millions of customers will receive complaints in higher raw numbers than a smaller rival. The useful question is whether its complaint record looks proportionate for its size, products and customer base - and whether the type of complaints would matter to you.
What insurer complaint data can tell you
UK insurers report complaints information to the Financial Conduct Authority (FCA). The published data can show how many complaints a firm received, how many were resolved within a set period, and how many were upheld. The Financial Ombudsman Service also publishes information on cases that reach it, including whether it agrees with the consumer.
Used together, these sources can help you identify patterns. An insurer with a higher-than-expected level of complaints about claims handling, for example, deserves closer attention if you are buying home, car or travel cover. A firm with a high proportion of complaints upheld may indicate that customers have had valid reasons to challenge its decisions or service.
The data is particularly helpful when two policies appear similar on price and headline cover. It can give you a reason to pay a little more for an insurer with a better service record, especially where a claim could be costly or disruptive.
That said, complaints data cannot tell you whether a particular insurer will be right for every customer. It is a useful check, not a substitute for reading the policy wording and comparing what is actually covered.
Start with the right comparison
Raw complaint totals are the easiest figures to misread. A household-name insurer may receive more complaints simply because it sells far more policies. Where available, look for complaints measured against the number of policies held or customers served. This offers a fairer view of how often customers complain.
Also compare like with like. Motor insurance complaints should be assessed against other motor insurers, not against a specialist life insurer or a bank that sells a very different mix of products. Some firms operate several brands, while others use separate legal entities for different product lines. Check that you are looking at the company that actually underwrites or administers the policy.
A low complaint figure is encouraging, but it is not proof of excellent service. Customers do not always complain formally. Some may switch at renewal, accept an unsatisfactory outcome, or not know how to raise the issue. Equally, a higher figure does not automatically mean poor treatment. A major insurer handling a large number of complex claims after storms, floods or widespread travel disruption may see complaints rise for reasons that need context.
Look at the type of complaint, not only the total
The reason behind a complaint is often more revealing than the number itself. When checking insurer complaint data, consider what stage of the customer journey seems to be causing friction.
Complaints around sales and renewals can point to unclear pricing, administration mistakes or confusion over policy changes. Claims complaints may be more serious, particularly if they relate to delays, disputes over settlement values, rejected claims or poor communication while a customer is without a car or dealing with damage at home.
For a low-value product, such as basic gadget cover, you may decide that price remains the main factor. For buildings insurance, private medical insurance or a comprehensive motor policy, claims service should carry more weight. Saving £20 a year is unlikely to feel worthwhile if a difficult claim becomes harder to manage.
It is also worth distinguishing between a complaint about an outcome and one about delay or communication. Insurers cannot pay every claim, particularly where an exclusion clearly applies. But customers should still receive a timely explanation, fair handling and a clear route to challenge a decision.
Use Ombudsman outcomes as a second check
If a complaint cannot be resolved directly with the insurer, a consumer may take it to the Financial Ombudsman Service. Ombudsman data can add a valuable independent perspective because it shows what happens when disputes are reviewed externally.
Pay attention to both the volume of cases and the proportion upheld in favour of consumers. A firm with relatively few cases reaching the Ombudsman may be resolving issues properly at an earlier stage. A high uphold rate can be a stronger warning sign than a high number of complaints alone, because it suggests the Ombudsman has found fault with the insurer's response.
There are limits here too. Ombudsman cases are usually more difficult or entrenched than ordinary complaints, so they are not a complete snapshot of all customers. Case volumes can also be small for niche providers, making percentages jump sharply from one period to another. Look for a pattern over time rather than reacting to a single reporting period.
A practical way to compare insurers
Before buying or renewing, narrow your options to two or three policies that meet your cover needs. Then use complaints information to test the quality behind the quote.
First, check whether each provider's complaint level appears reasonable for its size. Next, look for evidence of recurring problems in the product area you are considering. Then check Ombudsman outcomes, if available, to see whether there is a consistent gap between the insurer's decisions and independent findings.
Finally, put the figures alongside the policy details. Compare the excess, compulsory and voluntary, exclusions, cancellation terms, claims limits, repair arrangements and any restrictions that could affect you. Complaints data may help you choose between similar policies, but it cannot compensate for cover that does not suit your circumstances.
For example, a cheaper car policy may have a lower premium but a high compulsory excess, limited courtesy car provision and weaker claims feedback. If you rely on your car for work or school runs, a modestly more expensive policy with clearer benefits and fewer signs of claims friction could offer better value overall.
Warning signs worth taking seriously
One complaint figure should rarely decide the matter. Several signs together are more meaningful. Be cautious if you find a high complaint rate compared with similar insurers, repeated complaints about the same issue, a poor record of resolving complaints promptly, and a high proportion of Ombudsman cases upheld.
Customer reviews can provide colour around those figures, but treat them carefully. Online reviews tend to attract customers at either extreme: those who had a very good experience and those who are understandably frustrated. Look for recurring, specific themes rather than relying on a star rating or one dramatic story.
Be especially wary of reviews that focus on a broker when you are trying to judge the insurer, or vice versa. The broker may handle the sale and policy changes, while the insurer handles claims. Knowing who is responsible for each part of the service makes the feedback more useful.
When a higher complaint rate may be acceptable
There is no universal 'good' complaint rate. A specialist insurer may deal with higher-risk drivers, older properties or more complex medical conditions, all of which can lead to more difficult claims and more disputes. That does not excuse poor service, but it does mean comparisons need care.
A temporary spike can also have an understandable cause, such as severe weather affecting a large number of homes. What matters is how the insurer responds: whether it communicates clearly, deals with backlogs fairly and improves its processes afterwards.
The best choice depends on your priorities. If you need a simple annual policy and the cover is standard, price may rightly be a major deciding factor. If a claim would put real pressure on your finances, service quality and complaint patterns deserve more weight.
Do not wait until you need to complain
The most useful time to check an insurer's record is before you buy, not while you are trying to resolve a claim. Keep copies of your policy schedule, renewal documents and any important conversations. If something goes wrong, raise the issue promptly and explain the outcome you want.
Insurers have a formal complaints process and should give you a final response. If you remain unhappy, you may be able to refer the matter to the Financial Ombudsman Service within the relevant time limits. Clear records make that process easier.
A policy is more than a price shown on a comparison screen. Use complaint information to ask one practical question: if you need help at the worst possible moment, does this insurer give you enough confidence to choose it?
