UK Financial Ombudsman Complaints: A Practical Guide for 2026/27

When a bank, insurer, lender or investment firm gets it wrong and refuses to put things right, the Financial Ombudsman Service offers a free, independent route to a legally binding decision — no solicitor or court fee required. This pillar guide explains the eight-week rule that governs when you can escalate, the strict time limits for referring a case, what falls inside and outside the Ombudsman’s jurisdiction, how compensation and redress are calculated, and how to put together a complaint that gives you the best chance of a fair outcome.

What Is the Financial Ombudsman

The Financial Ombudsman Service is a statutory, free dispute-resolution service for complaints between consumers (and many small businesses) and financial firms authorised or regulated by the Financial Conduct Authority. It covers banks, building societies, credit card issuers, insurers, mortgage lenders, investment firms, pension providers, claims management companies and payday and other consumer credit lenders that fall within FCA regulation.

Its decisions, once accepted by the consumer, are legally binding on the financial firm. It is important to distinguish the Ombudsman’s role — resolving individual disputes fairly — from that of the Financial Conduct Authority, the regulator responsible for setting and enforcing industry-wide rules and taking enforcement action against firms.

The Eight-Week Rule

You must complain directly to the financial firm first. The firm then has up to eight weeks to investigate and issue a “final response” — its formal written decision on your complaint. If the firm resolves the matter to your satisfaction within that time, the process ends there. If the firm sends a final response before the eight weeks are up and you disagree with it, you can refer the complaint to the Ombudsman immediately.

If eight weeks pass with no final response at all, you do not have to keep waiting — you can go straight to the Ombudsman. The final response letter should also set out your referral rights and the applicable deadline, so keep it safely once received.

Time Limits

Two separate time limits generally apply. After receiving the firm’s final response, you normally have six months to refer the complaint to the Ombudsman, or you risk losing the right to have it considered at all. Separately, the underlying event you are complaining about is usually only eligible if raised within six years of it happening, or within three years of when you first knew (or reasonably should have known) you had grounds to complain, if that is later.

The Ombudsman has limited discretion to look at complaints outside these limits in exceptional circumstances, but this should never be relied upon — act promptly once you receive a final response or become aware of a problem.

What the Ombudsman Covers

Typical complaint categories include mis-sold financial products and poor advice (investments, pensions, mortgages), unfair charges or interest, mishandled insurance claims (unreasonable rejection, delay or underpayment), irresponsible lending where affordability was not properly assessed, packaged bank account fees for unused benefits, and fraud or scam disputes with your bank, including Authorised Push Payment fraud reimbursement disputes.

The Ombudsman cannot deal with firms outside FCA authorisation, cannot award punitive damages, cannot change a firm’s general commercial terms for all customers, and cannot revisit matters already decided by a court. For complaints about occupational pension schemes specifically, the Pensions Ombudsman, rather than the FOS, is usually the correct body.

Compensation and Redress

For acts or omissions on or after 1 April 2019, the Ombudsman’s award limit is £415,000 (this figure is reviewed annually for inflation by the FCA, so always confirm the current limit on financial-ombudsman.org.uk before relying on it). Lower historic limits apply to older complaints. Where actual loss exceeds the binding award limit, the Ombudsman can recommend the firm pay the balance, though this recommendation is not enforceable in the same binding way — very high-value disputes may be better pursued through the courts from the outset.

The aim of redress is to put you back in the position you would have been in had the problem not occurred: a refund of unfair charges with interest (commonly 8% simple per year), compensation for demonstrable financial loss from bad advice, correction of an inaccurate credit file entry, or reimbursement of a fraudulent payment. Awards specifically for distress and inconvenience tend to be modest relative to financial loss awards.

Building a Strong Complaint

Set out events in clear date order, state plainly what went wrong, what the firm did or failed to do, and precisely what outcome you are asking for — a refund, a specific sum of compensation, a corrected credit reference entry, or reimbursement of a loss. Attach supporting evidence: statements, correspondence, screenshots, call reference numbers and any written confirmation from the firm.

Keep a complete record of the complaint you sent the firm and its response, since this timeline evidences both the eight-week rule and the six-month referral deadline. A factual, well-organised complaint is generally assessed more quickly and accurately than a long unstructured account, even where your underlying experience has genuinely been stressful.

What Happens After You Refer

Most complaints are first assessed by an investigator (adjudicator), who reviews both sides’ evidence and issues a written assessment recommending an outcome. If either side disagrees, the case can be escalated for a final decision from an Ombudsman, which is more formal and, once accepted by the consumer, legally binding.

Straightforward complaints can resolve in a few months; complex or high-volume categories (such as the recent surge in motor finance commission complaints) can take considerably longer given caseload pressures. The FOS website publishes current indicative timescales.

Accepting, Rejecting and Going Further

If you accept a final decision, it becomes binding on the firm and the matter is generally closed, including for court purposes. If you are unhappy with the outcome, you are not obliged to accept it and can instead consider pursuing the matter through the county court, though for most consumers the free FOS route, with no fee and no costs risk, remains the sensible first (and often only necessary) step for financial services disputes.

FAQs

What is the Financial Ombudsman Service?

The Financial Ombudsman Service (FOS) is a free, independent dispute-resolution body set up by law to resolve complaints between consumers and financial firms — banks, insurers, lenders, pension providers, investment firms, claims management companies and more — that are authorised or regulated by the Financial Conduct Authority. It is entirely free for consumers to use and its decisions, once accepted by the consumer, are legally binding on the financial firm. It is not a regulator and cannot fine firms or change industry-wide rules; that is the role of the Financial Conduct Authority.

What is the eight-week rule?

You must normally complain to the financial firm itself first and give it up to eight weeks to investigate and respond before the Financial Ombudsman Service will consider your case. If the firm sends a "final response" letter (their formal decision) before eight weeks are up and you are unhappy with it, you can escalate to the FOS immediately without waiting the full eight weeks. If eight weeks pass with no final response, you can also go straight to the FOS. The final response letter should include information about your right to refer the matter to the Ombudsman and the time limit for doing so.

What time limits apply to a Financial Ombudsman complaint?

Two time limits typically apply and both must usually be met. First, once the firm sends its final response, you generally have six months from the date of that letter to refer the complaint to the FOS, or you may lose the right to have it considered. Second, the underlying complaint itself is normally only eligible if you refer it within six years of the event complained about, or (if later) within three years of when you became aware, or reasonably should have become aware, that you had cause to complain. The FOS retains some discretion to consider late complaints in exceptional circumstances.

What kinds of complaints can the Ombudsman deal with?

Common complaint categories include: mis-sold financial products (PPI historically, but also mis-sold investments, pensions and insurance); unfair or incorrect charges and interest; poor advice from a mortgage broker or financial adviser; mishandled insurance claims (unfair rejection, unreasonable delay, underpayment); irresponsible lending (loans or credit granted without proper affordability checks); packaged bank account fees for benefits never used; and fraud and scam disputes involving banks, including Authorised Push Payment (APP) fraud reimbursement disputes under the mandatory reimbursement scheme.

What can the Ombudsman NOT do?

The FOS cannot deal with complaints about firms that are not authorised or regulated by the FCA (unregulated lenders, most cryptocurrency exchanges, and some peer-to-peer platforms fall outside jurisdiction unless specifically FCA-regulated). It cannot award punitive damages, cannot compel a firm to change its general commercial terms for all customers, cannot deal with matters already decided by a court, and cannot act as a regulator investigating systemic wrongdoing — that role belongs to the FCA. For complaints outside its remit, the small claims court, the relevant industry regulator, or a specialist ombudsman (such as the Pensions Ombudsman for occupational pension scheme disputes) may be the right route instead.

Is there a limit on how much compensation the Ombudsman can award?

Yes. For complaints about acts or omissions by firms on or after 1 April 2019, the FOS award limit is £415,000 (this limit is reviewed annually for inflation by the FCA and can change; always check the current figure on financial-ombudsman.org.uk before assuming a specific value). For complaints about events before that date, lower historic limits apply. Where your loss genuinely exceeds the award limit, the Ombudsman can still recommend the firm pay the excess, though this recommendation is not legally binding in the same way as the award itself — pursuing the excess through the courts remains an option in high-value cases.

How is redress or compensation calculated?

The Ombudsman aims to put you back in the position you would have been in had the problem not occurred — this could mean a refund of unfair charges plus interest, compensation for financial loss caused by bad advice, a corrected credit file entry, or reimbursement of a scam payment. Awards for distress and inconvenience are typically modest compared with financial loss awards, reflecting the Ombudsman's approach of proportionate, fair redress rather than punitive damages. Interest, often at a standard rate of 8% simple per year, is commonly added to reflect the time you were out of pocket.

How do I make a strong complaint?

Set out the facts in date order, be specific about what went wrong and what outcome you want (a refund, compensation, a correction to your credit file), and attach supporting evidence: correspondence, statements, call recordings if available, and screenshots. Keep a clear paper trail of your complaint to the firm and its response. When referring to the Ombudsman, the online complaint form asks for the same core information; being factual, concise and evidence-led generally produces a faster and more accurate outcome than a lengthy emotional narrative, even where the underlying experience has genuinely been distressing.

How long does a Financial Ombudsman case take?

Simple complaints can be resolved informally by an adjudicator within a few months; more complex cases, or those where either party disagrees with the adjudicator's assessment and asks for a final decision from an Ombudsman, can take a year or more given current caseloads, which have been elevated in recent years partly due to high volumes of motor finance commission complaints. The FOS publishes indicative timescales and case examples on its website, though individual case timing varies considerably by complexity and firm responsiveness.

Is the Ombudsman decision final, and can I still go to court?

If you accept an Ombudsman's final decision, it becomes legally binding on the firm (though not on you) and effectively ends the matter — you generally cannot then pursue the same complaint through the courts. If you are unhappy with the outcome, you do not have to accept it; you can instead choose to pursue the matter through the county court (or, in limited grounds such as procedural unfairness, seek judicial review of the Ombudsman's decision), though using the free FOS route first, given no fee and no cost risk, remains the sensible starting point for most consumer financial disputes.

About the author

James Morgan

Property & Mortgage Writer

James Morgan has been writing about UK property and mortgages since 2016. He covers the full purchase journey — affordability checks, mortgage product comparison, the deposit and loan-to-value puzzle, stamp duty (SDLT in England and Northern Ireland, LBTT in Scotland, LTT in Wales), first-time buyer reliefs, conveyancing costs, and what to expect at completion. James also writes on the landlord side: buy-to-let mortgages, the 3% additional-property SDLT surcharge, Section 24 finance-cost restriction, rental yield maths, and the practical realities of being a small private landlord in the post-2017 tax regime. He has a particular interest in the remortgage decision — when to switch product, the trade-off between rate and arrangement fee, early repayment charges, and how to read a mortgage offer document. James's mortgage worked examples are built up from the underlying amortisation schedule, not borrowed from comparison sites, and stamp-duty figures are verified band-by-band against the HMRC SDLT calculator. He writes to CalcHub's editorial standards, with primary-source citations to HMRC, Revenue Scotland and the Welsh Revenue Authority, and clear disclosure that CalcHub does not sell mortgages or take affiliate commission on regulated mortgage products.
