Financial Ombudsman Service and Insurance Complaints UK

Introduction

Most of our guides across ShopTera mention, briefly, that if you're unhappy with your insurer you can ultimately take a complaint to the Financial Ombudsman Service. This guide goes into that process properly: what your insurer is required to do when you complain, what a "final response" actually means, when and how you can escalate to FOS, what FOS can and can't help with, and roughly how compensation works when a complaint is upheld.

If your complaint specifically concerns how a cancellation, refund or cooling-off request was handled, see our Cancelling Insurance and the Cooling-Off Period UK guide for a full explanation of your underlying rights before escalating.

This is a general educational guide to the complaints and dispute resolution process, not legal advice, and it does not cover the separate question of what happens if your insurer becomes insolvent, which is addressed in our FSCS Protection for Insurance UK guide instead.

Key Terms Explained

Financial Ombudsman Service (FOS)

A free, independent service set up by Parliament to resolve complaints between consumers and financial businesses, including insurers, when a business's own complaints process hasn't resolved things.

Final Response

The formal written outcome an insurer must send once it has finished investigating your complaint, explaining its decision and your right to refer the matter to FOS.

Jurisdiction

The scope of complaints FOS has the legal power to consider, set out in the Financial Conduct Authority's DISP rules.

Redress or Compensation

What FOS can tell a business to do to put things right, which may include paying a specific amount, reimbursing costs, or correcting a non-financial issue such as a credit file entry.

Award Limit

The maximum amount FOS can formally require a business to pay in a given case, which varies depending on when the complaint was referred and when the underlying issue occurred.

Step 1: Complain to Your Insurer

Every insurance complaint has to start with the insurer itself. Contact them directly, explain clearly what's happened or what you think has gone wrong, and say how you'd like it put right. Most complaints are resolved at this stage without needing to go any further.

Finding the Right Contact

Your insurer's complaints process is usually set out on their website, in your policy documents, or available from their customer service team. The Financial Conduct Authority also maintains a public register of regulated financial businesses if you need to confirm contact details.

Keep a Record

Keep notes of calls, emails and any other correspondence with your insurer about the issue, along with dates and names where possible. This evidence genuinely helps if the complaint later needs to go to FOS, since they'll ask to see your insurer's final response and may ask about the history of the complaint.

Tell Your Insurer If You're in a Vulnerable Position

If you're seriously ill, in financial difficulty, or need help urgently, let your insurer know as soon as you can. Depending on the circumstances, they may be able to look at your complaint more quickly than the standard time limits.

Step 2: The Final Response

There are rules that financial businesses, including insurers, must follow when investigating a complaint. They're expected to consider what's happened quickly and fairly, and to keep you updated throughout.

How Long Your Insurer Has to Respond

For most complaints, an insurer has up to 8 weeks to consider a complaint and issue a final response. A shorter 15-day time limit applies specifically to complaints about fraud and scams, payment services such as bank transfers or direct debits, and electronic money. If you haven't received a response within the applicable time limit, you can refer your complaint to FOS without waiting any longer.

What the Final Response Should Include

Once your insurer has finished investigating, they'll send a final response setting out the outcome of your complaint and how to take things further if you remain unhappy. It should also mention your right to refer the complaint to FOS within 6 months, and state whether the insurer agrees to FOS looking into the complaint if you bring it after that time limit has passed. If an insurer agrees to this in writing, it can't change its mind later.

Step 3: Referring to the Financial Ombudsman Service

If you're not satisfied with your insurer's final response, or the time limit for a response has passed without one arriving, you can bring your complaint to FOS.

The Service Is Free

FOS doesn't charge consumers to investigate a complaint, and you don't need to pay a solicitor or claims management company to represent you. You can ask a family member, friend or someone else to help you with your complaint if you'd like support putting it together.

What You'll Need to Provide

You'll generally need to answer questions about what happened, the insurer involved, and what you'd like to see happen as a result, usually through an online complaint form. Providing your insurer's final response and any supporting evidence you have helps FOS assess your complaint more quickly.

What Happens Next

FOS will first check whether it has the power to consider your complaint at all, based on its jurisdiction and the applicable time limits. If it can help, an investigator will typically look at the case and reach an initial view. If either side disagrees with that view, the complaint can be escalated to a final decision from an ombudsman.

Time Limits at a Glance

Exceptions to the 6-Month Referral Window

Missing the 6-month window to refer a complaint to FOS usually means it can't be considered, but there are limited exceptions: where exceptional circumstances, such as a period of serious ill health or a bereavement, are shown to have genuinely prevented you from referring the complaint on time; where the insurer didn't send a valid final response; or where the insurer agrees to FOS being involved despite the time limit having passed.

What FOS Can Help With

FOS can generally help with complaints about the way a financial business has treated you, including insurers, across a wide range of product areas.

Insurance Complaints

This includes home, travel, motor, wedding and most other types of personal insurance, whether the complaint relates to a claim decision, delay, mis-selling, or how you were treated as a customer.

Other Financial Products

Beyond insurance, FOS also covers banking and payments, credit and borrowing, fraud and scams, investments, mortgages, pensions and annuities, pre-paid funeral plans, and complaints about claims management companies, which are themselves FCA-regulated firms with their own fee caps and conduct rules.

What FOS Cannot Help With

FOS won't be able to help with every complaint, and it will let you know if this applies to yours.

Reasons a Complaint Might Fall Outside FOS's Remit

• The complaint is outside the applicable time limits, without a recognised exception applying.
• The type of complaint should be dealt with by a different ombudsman scheme entirely, such as one covering utilities, telecoms, legal services or housing.
• The complaint has already been looked at by FOS previously, or has already been decided by a court.
• The complaint otherwise falls outside FOS's jurisdiction, as set out in the Financial Conduct Authority's DISP rules.

If FOS can't help with your specific complaint, it's worth asking whether another ombudsman scheme covers the issue instead, since several exist for different sectors.

Compensation and Redress

Where FOS decides you've lost out financially because of how a business treated you, it has the power to tell that business to put things right.

How Compensation Can Be Awarded

This might mean awarding a specific amount where the loss is clear, telling the insurer to reimburse certain costs, or setting out how the insurer should calculate what you're owed where the exact figure isn't straightforward. FOS can also require non-financial remedies, such as correcting an inaccurate entry on a credit file.

The Award Limit

There is a published limit to how much FOS can formally require a business to pay, and this limit changes periodically and depends on both when your complaint is referred and when the underlying issue occurred. As of 2026, the published figure is £455,000 for complaints referred on or after 1 April 2026 relating to acts or omissions on or after 1 April 2019; lower limits apply to complaints referred in earlier periods or relating to older issues. FOS can recommend that a business pays more than the limit if it believes that's fair, though the business is not obliged to accept that recommendation. Always check the current limit directly with FOS, since it is reviewed and can change.

Interest and Tax

FOS may also tell a business to add interest to an award, for example where you were deprived of money you should have had. Compensation can also have tax implications depending on the type of award and your personal circumstances, so it's worth checking with HMRC if you're unsure what applies to you.

FOS vs FSCS: Two Different Protections

These two organisations are frequently confused, but they exist to solve entirely different problems, and it's worth being clear about which one applies to your situation.

Financial Ombudsman Service: Resolving Disputes

FOS exists to resolve disagreements between you and a financial business, including your insurer, about how you've been treated: a declined claim you think was unfair, a delay you weren't compensated for, or a sale you believe was mishandled. It's a dispute resolution service, not an insolvency protection scheme.

FSCS: Protecting You If a Business Fails

The Financial Services Compensation Scheme protects you financially if your insurer itself becomes insolvent and cannot pay valid claims or refunds, an entirely different and much rarer scenario than a straightforward complaint about service or a claim decision. Our FSCS Protection for Insurance UK guide explains how that protection works, including the 90% and 100% protection levels that can apply.

Why the Distinction Matters

If your insurer is solvent and trading normally but you disagree with how they've handled your claim or your account, FOS is the relevant route. If your insurer has actually failed as a business, FSCS is the relevant protection instead. The two are not alternatives to each other, and using the wrong one first can simply cause delay.

Real-World Examples

Common Mistakes to Avoid

• Contacting FOS before giving the insurer the chance to investigate and issue a final response.
• Losing track of the final response letter, which starts the 6-month referral window.
• Assuming there's no time limit at all for referring a complaint to FOS.
• Confusing FOS's dispute resolution role with FSCS's insolvency protection role.
• Paying a claims management company when FOS's own service is free to use directly.
• Not mentioning a vulnerable circumstance, such as serious illness, that might affect how quickly a complaint can be handled.

Common Myths

• Myth: You can go straight to the Financial Ombudsman Service without complaining to your insurer first. FOS generally only gets involved once your insurer has had the chance to investigate and issue a final response, or the relevant time limit has passed.
• Myth: FOS and FSCS are the same thing, or interchangeable. FOS resolves disputes about how you've been treated; FSCS protects you financially if an insurer becomes insolvent. They address different problems.
• Myth: You need to pay someone to bring a complaint to FOS. The service is free to use directly, and you don't need a solicitor or claims management company to represent you.
• Myth: There's no limit to how much compensation FOS can order. There is a published award limit that applies to formal awards, though FOS can recommend a business pay more voluntarily.

Conclusion

Complaining about your insurer follows a clear structure: raise it with the insurer first, allow them the time limit that applies to investigate and issue a final response, and only then, if you're still unhappy or haven't heard back, bring the matter to the Financial Ombudsman Service, generally within 6 months of that final response. FOS is free, independent, and entirely separate from FSCS, which protects you in the different scenario of an insurer's outright financial failure.

Keeping your final response letter safe, understanding the time limits that apply, and knowing which of these two services genuinely fits your situation will save time if you ever need to escalate a genuine dispute with your insurer.

Next Steps

• If you haven't already, raise your complaint directly and clearly with your insurer first.
• Keep a dated record of all correspondence and your insurer's final response.
• Check the time limit that applies to your type of complaint before assuming you're too early or too late.
• If you remain unhappy after a final response, consider referring your complaint to the Financial Ombudsman Service.
• Confirm whether FOS or FSCS is actually relevant to your situation before proceeding.
