How complaints handling works under the FCA DISP sourcebook: what a complaint is, the 8 week and 3 business day deadlines, and ombudsman referrals.

Complaints handling is one of the clearest tests of whether a firm treats its customers fairly. The Financial Conduct Authority sets out the rules in the Dispute Resolution: Complaints sourcebook, known as DISP. These rules tell you what counts as a complaint, how quickly you must respond, what your response must contain, when a customer can escalate to the Financial Ombudsman Service, and what you must report back to the regulator.
The rules apply whether you are a large bank or a small authorised firm. They do not reward firms that make complaints hard to raise or slow to resolve. Instead, DISP builds a consistent framework so that every eligible complainant receives a fair hearing, a prompt answer, and a clear route to an independent decision if they remain dissatisfied.
This guide walks through the parts of DISP that matter most in day to day operations. Every deadline and rule below is taken directly from the FCA Handbook and the Financial Ombudsman Service. Where a rule sets a specific period, we cite where it comes from so you can check it against the source.
The starting point is the FCA definition of a complaint. The Handbook glossary defines it as any oral or written expression of dissatisfaction, whether justified or not, from or on behalf of a person about the provision of, or failure to provide, a financial service. The expression must allege that the complainant has suffered, or may suffer, financial loss, material distress or material inconvenience.
Three features of that definition catch firms out. First, a complaint can be oral. A phone call or a comment in a branch counts, so front line staff need to recognise dissatisfaction when they hear it, not only when it arrives by letter or email. Second, it does not matter whether the complaint is justified. You still handle it under DISP even if you are confident the firm did nothing wrong. Third, the person does not need to have already suffered a loss. An allegation that they may suffer financial loss, material distress or material inconvenience is enough to bring the matter into scope.
Getting this recognition right at the front line is the foundation of a compliant process. If a firm quietly resolves grumbles without logging them, it will under record complaints, miss the reporting obligations described later, and lose the management information it needs to spot recurring problems.
DISP 1.3.1R requires every respondent to establish, implement and maintain effective and transparent procedures for the reasonable and prompt handling of complaints. This is not a paperwork exercise. The word transparent means customers should understand how to complain and what will happen next, and the word effective means the process must actually deliver fair and timely outcomes.
In practice this means a documented complaints policy, trained staff, a way to capture complaints from every channel, and a route for identifying and correcting recurring or systemic problems that the complaints reveal. It also means the firm can distinguish a complaint from a routine query, so that genuine complaints enter the regulated process rather than being handled informally and then forgotten.
Firms should treat their complaints data as an early warning system. A cluster of complaints about one product, one process or one team is a signal worth acting on before it becomes a wider conduct issue. A robust control framework helps you turn complaints into evidence rather than noise. You can see how we approach this in our control tooling.
Not every complaint needs a full investigation. DISP 1.5 provides a lighter route for complaints that a firm resolves quickly. Under DISP 1.5.1R, some of the usual complaint handling requirements do not apply where the complaint is resolved by the close of business on the third business day following the day it is received.
A complaint is treated as resolved for this purpose where the complainant has indicated acceptance of the firm response, and DISP 1.5.2AR makes clear that neither the response nor the acceptance has to be in writing. If the customer has not accepted the outcome, you cannot treat the matter as resolved on this fast track and it moves into the standard process with the longer deadline.
Where the fast track applies, DISP 1.5.4R still requires the firm to send a written summary resolution communication promptly. That communication must refer to the fact that the complainant made a complaint, state that the firm now considers it resolved, tell the complainant that they may be able to refer the matter to the Financial Ombudsman Service, indicate whether the firm consents to waive the relevant time limits, and give the ombudsman website address. In short, resolving a complaint quickly reduces the process burden but never removes the duty to signpost the ombudsman.
For complaints that are not resolved on the fast track, the central deadline is set by DISP 1.6.2R. By the end of eight weeks after receiving the complaint, the firm must send the complainant either a final response or a written response explaining why it is not yet able to give a final response and when it expects to do so.
A final response is the firm formal answer. It accepts the complaint and, where appropriate, offers redress or remedial action, or it rejects the complaint and gives reasons. Under DISP 1.6.2R the final response must also enclose a copy of the Financial Ombudsman Service standard explanatory leaflet, give the ombudsman website address, tell the complainant that they may refer the complaint to the ombudsman if they remain dissatisfied, and indicate whether the firm consents to waive the relevant time limits.
The eight week point matters for a second reason. Once eight weeks have passed without a final response, an eligible complainant generally gains the right to take the complaint to the Financial Ombudsman Service even though the firm has not finished its investigation. Treating eight weeks as a hard operational ceiling, and aiming to answer well inside it, keeps control of the outcome with the firm rather than passing it to the ombudsman by default.
The Financial Ombudsman Service is the independent body that resolves disputes between financial firms and their customers. DISP requires firms to point eligible complainants towards it, both in a summary resolution communication and in a final response. This signposting is not optional, because it is the customer route to an independent decision.
There are important time limits on referral, set out in DISP 2.8.2R. The ombudsman cannot normally consider a complaint if the complainant refers it more than six months after the date the firm sent its final response, redress determination or summary resolution communication. There is also a longer stop: the ombudsman generally cannot consider a complaint referred more than six years after the event complained of, or if later, more than three years from the date the complainant became aware, or ought reasonably to have become aware, that they had cause to complain. The ombudsman may still consider a complaint outside these limits in exceptional circumstances.
For firms this means the wording of your final response has real consequences. The six month clock starts from the date you send that response, so the response must clearly state the customer right to escalate and enclose the ombudsman leaflet. Missing that signposting can leave a customer unable to exercise their rights.
Not everyone can take a complaint to the Financial Ombudsman Service. DISP 2.7 sets out who qualifies as an eligible complainant. The category covers consumers, and it also extends to certain smaller organisations, so a complaint must arise from a relevant relationship with the firm, such as the complainant being, or having been, a customer.
The rules set size thresholds for non consumer complainants. Under DISP 2.7.3R a charity qualifies where it has an annual income of less than £6.5 million, and a trustee of a trust qualifies where the trust has a net asset value of less than £5 million. The Financial Ombudsman Service also helps micro-enterprises and small businesses. The ombudsman explains that a micro-enterprise is one that has fewer than 10 employees and a turnover or annual balance sheet total that does not exceed 2 million euro, while a small business is broadly one with an annual turnover of less than £6.5 million that employs fewer than 50 people or has a balance sheet total of less than £5 million.
The practical point is that eligibility is not just about whether the person is an individual. Firms should assess eligibility carefully, because it determines whether the ombudsman signposting applies and whether the customer has an independent route if they remain dissatisfied. When in doubt, signpost, because it is safer to tell a customer about the ombudsman than to wrongly assume they cannot use it.
| Eligible complainant type | Threshold under DISP 2.7 or the ombudsman |
|---|---|
| Consumer | No size threshold |
| Charity | Annual income of less than £6.5 million |
| Trustee of a trust | Trust net asset value of less than £5 million |
| Micro-enterprise | Fewer than 10 employees and turnover or balance sheet not over 2 million euro |
| Small business | Turnover under £6.5 million and fewer than 50 employees or balance sheet under £5 million |
Handling complaints well is only part of the obligation. Firms must also report complaints data to the FCA so the regulator can monitor conduct across the market. DISP 1.10 sets out the complaints reporting rules. Most firms report twice a year, with the reporting periods tied to the firm accounting reference date, while some firms with limited permissions report once a year.
Under DISP 1.10.5R, reports must be submitted within 30 business days of the end of the relevant reporting period, through the electronic system the FCA specifies. The level of detail depends on volume, because a firm receiving 500 or more complaints in a reporting period uses the fuller reporting format. Firms that submit a report showing 500 or more complaints must also publish a summary of that complaints data, and the FCA in turn publishes consolidated complaints data drawn from firm returns.
Accurate reporting depends on accurate logging at the front line, which is why the definition of a complaint and the reporting return are two ends of the same process. If complaints are under recorded, the return will understate them and the firm risks a data quality issue and an administrative fee for a late or incomplete return. Joining up capture, resolution and reporting turns complaints handling from a reactive chore into a genuine control.
Selected deadlines drawn from the DISP sourcebook. The summary resolution route uses business days, the final response deadline uses weeks, and the reporting submission uses business days.
Complaints handling under DISP follows a clear logic. Recognise a complaint using the wide FCA definition, run it through fair and prompt procedures, resolve it quickly where you can under the three business day summary resolution route, and otherwise send a final response no later than eight weeks after receipt. At every stage, tell eligible complainants about their right to escalate to the Financial Ombudsman Service, and remember the six month referral window that starts when you send your response.
Firms that treat these rules as an operational discipline rather than a box ticking exercise tend to complain less about complaints. Good capture at the front line, fair investigation, clear final responses and accurate reporting all reinforce one another.

The FCA Handbook glossary defines a complaint as any oral or written expression of dissatisfaction, whether justified or not, about the provision of, or failure to provide, a financial service, where the person alleges they have suffered or may suffer financial loss, material distress or material inconvenience. It includes complaints made by phone, and it applies even if the firm believes the complaint is not justified.
Under DISP 1.6.2R, a firm must send a final response, or a written response explaining why it cannot yet do so, by the end of eight weeks after receiving the complaint. Once eight weeks pass without a final response, an eligible complainant generally gains the right to refer the complaint to the Financial Ombudsman Service.
DISP 1.5 provides a lighter route for complaints resolved by the close of business on the third business day after the day the complaint is received, where the complainant has indicated acceptance of the response. The firm must still send a written summary resolution communication that signposts the Financial Ombudsman Service, under DISP 1.5.4R.
Under DISP 2.8.2R, the ombudsman cannot normally consider a complaint referred more than six months after the firm sent its final response, redress determination or summary resolution communication. Longer stops of six years from the event, or three years from awareness if later, also apply, subject to exceptional circumstances.
DISP 2.7 sets out who can use the Financial Ombudsman Service. It covers consumers and certain smaller organisations, including charities with an annual income of less than £6.5 million and trustees of trusts with a net asset value of less than £5 million, plus micro-enterprises and small businesses that meet the ombudsman size thresholds.
Yes. Under DISP 1.10 most firms report complaints data to the FCA twice a year, and reports must be submitted within 30 business days of the end of the reporting period. Firms that report 500 or more complaints in a period use the fuller format and must also publish a summary of that complaints data.
