Customer Complaints Handling Checklist Template

A complaint starts a regulatory clock the moment it arrives, whether it came by letter, phone or a chat window. Most missed deadlines start with a complaint nobody logged on day one.

This free complaints handling checklist takes one customer complaint at a regulated firm from receipt to closure. It is for complaints teams and compliance officers at banks, lenders, payment firms, insurers, brokers and wealth managers. Two answers at the start shape the rest: whether the complaint falls under UK or US rules, and whether it is also a billing or transfer error dispute with its own statutory deadline. Only the phases that apply appear. Outcomes and redress go to a named approver before the customer hears the decision, and every complaint closes with a root cause.

One Complaint, Three Possible Clocks

In the UK the FCA’s Dispute Resolution: Complaints sourcebook, known as DISP, defines a complaint broadly: any oral or written expression of dissatisfaction, justified or not, that alleges the customer has suffered, or may suffer, financial loss, material distress or material inconvenience. It is a complaint even if the customer never uses the word, and the rules then set the acknowledgement, the response deadline and the route to the Financial Ombudsman Service.

The US has no single equivalent. Complaints sent through the Consumer Financial Protection Bureau come with a response deadline, and examiners review complaint handling as part of a firm’s compliance management system. A complaint about a disputed card charge or electronic transfer can also be a formal error notice under Regulation Z or Regulation E, with a statutory deadline that no complaint policy can extend.

UK: FCA DISP

Most regulated firms

Clock starts: on receipt, through any channel.

Deadline: 8 weeks for most complaints; 15 business days for payment services and e-money.

Output: a final response with ombudsman referral rights.

US: complaint

Firm policy and regulator portals

Clock starts: on receipt, or when a regulator forwards it.

Deadline: your own policy; 15 days in the CFPB portal, final response within 60.

Output: a written response and a UDAAP risk check.

US: error dispute

Regulation E or Regulation Z

Clock starts: on the consumer’s error notice.

Deadline: 10 business days or provisional credit for transfers; two billing cycles for card billing errors.

Output: a corrected account or a written explanation.

What the Complaints Handling Checklist Covers

Four phases run on every complaint. Three switch on from the Phase 1 answers: the error dispute, UK response and US response phases.

Phase 1

Phase 1: Receive, Log & Classify

Assigned to whoever receives the complaint. The answers recorded here decide which later phases appear.

  • Log the complaint on the day it arrives — date and time received, channel, customer, product and who took it; the clock runs from receipt
  • Confirm it is a complaint and not only a query — any expression of dissatisfaction that alleges loss, distress or inconvenience counts, whatever words the customer used
  • Record the jurisdiction — UK (FCA DISP) or US; the answer switches on Phase 5 or Phase 6
  • Record whether it is also a billing or transfer error notice — a disputed card charge or electronic transfer; a Yes opens Phase 2
  • Record any sign of vulnerability and the preferred channel — so the handler can adapt how they communicate
  • Send the acknowledgement and set the due date — UK rules require a prompt written acknowledgement; record the final response date in a Date field
  • Assign an investigator who was not involved — never the person whose conduct is complained about
Phase 2 — Error Disputes Only

Phase 2: Billing & Transfer Error Dispute

Shown only when the complaint is also a US billing or transfer error notice. It runs alongside the investigation.

  • Check the notice was given in time — both regulations give the consumer 60 days from the relevant statement; record the statement date
  • Electronic transfers: finish within 10 business days — or provisionally credit within 10 to take up to 45 days; 20 and 90 days for new accounts, point-of-sale and foreign transfers
  • Card billing errors: acknowledge in writing within 30 days — unless the error is resolved within that time
  • Card billing errors: resolve within two complete billing cycles and no more than 90 days — do not collect the disputed amount or report it as delinquent meanwhile
  • Report the result to the consumer — for transfers, within 3 business days of finishing the investigation
  • Correct the error, or reverse any provisional credit with the required notice — attach the notices and record the dates
Phase 3

Phase 3: Investigate

  • Gather the evidence — account records, call recordings, letters and the staff account of what happened
  • Ask the customer for anything missing and the outcome they want — record the reply date
  • Assess the complaint against the rules, the contract and what the customer was told — and against what a fair outcome looks like
  • Search for related complaints on the same issue — a repeat pattern is a root-cause signal, not just another case
  • Escalate if a trigger applies — threatened legal action, regulator or media interest, a possible rule breach, fraud or financial crime
  • Record the findings and a recommended outcome — upheld, partly upheld or not upheld, with reasons
Phase 4

Phase 4: Decision, Redress & Approval

The outcome goes to the complaints manager as an approval task. Redress above the handler’s authority limit goes to the named approver.

  • Calculate redress — put the customer back where they would have been: refund, interest and fees, plus an amount for distress or inconvenience where it applies
  • Check the outcome is consistent with similar complaints — inconsistency is a frequent audit finding
  • Complaints manager approval of the outcome — Approved or Not approved; Not approved returns the file to the investigator
  • Approve redress above the handler’s authority limit — the named approver records the amount signed off
  • Pay redress and confirm it reached the customer — record the date and payment reference
Phase 5 — UK Only

Phase 5: UK Response & Ombudsman Rights

Shown only when the jurisdiction is UK. Deadlines follow DISP 1.5 and DISP 1.6.

  • Resolved by close of the third business day after receipt? Send a summary resolution communication — in writing, confirming it is treated as resolved and explaining the right to go to the ombudsman
  • Otherwise send the final response by the deadline — within 8 weeks; for payment services and e-money, 15 business days, or 35 with a holding reply in exceptional circumstances
  • If the deadline cannot be met, send a written explanation — why, when you expect to respond, and that the customer may now refer the complaint to the ombudsman
  • Check the final response content — outcome and reasons, any offer, ombudsman referral rights and the six-month limit, the standard wording on waiving time limits, and the ombudsman’s website and leaflet
  • Record the date the final response was sent — the customer’s six months to refer runs from it
  • Flag the complaint for the half-yearly complaints return — complaints resolved within three business days are reported too
Phase 6 — US Only

Phase 6: US Response & Regulator Portals

Shown only when the jurisdiction is US. Your complaint policy and any state or regulator deadlines apply alongside.

  • Check whether the complaint also came through the CFPB or another regulator — link the portal reference to the checklist
  • Respond in the CFPB portal within 15 days — if more time is needed, mark it in progress and send a final response within 60 days
  • Answer any state or prudential regulator referral by its deadline — attach the response
  • Send the customer a written response — outcome, reasons, any remedy and how to take it further
  • Review the complaint for UDAAP and fair lending risk — repeated complaints about the same practice can point to an unfair, deceptive or abusive act
Phase 7

Phase 7: Close, Root Cause & MI

  • Classify the root cause — product design, process, people, systems, communication or a third party
  • Decide whether other customers are affected — if so, raise it for proactive remediation rather than waiting for more complaints
  • Log corrective actions with owners and dates — process fixes, training, product or letter changes
  • Record any ombudsman or regulator referral and its outcome — and reopen the file if the outcome changes the redress
  • Retain the complaint record — UK: at least three years, five for MiFID business; US: your record retention schedule
  • Feed the monthly complaints MI — volumes, uphold rates, time to resolve, redress paid and top root causes

Complaint Deadlines and the Rules Behind Them

The table maps each part of the checklist to its main UK and US source. Obligations depend on your firm type, products and regulators, so treat it as a starting point, not legal advice.

Several things are moving. The Financial Ombudsman Service has wider grounds to dismiss complaints referred from 1 October 2026, and is piloting a registration stage for new cases, with rule changes not expected before April 2027. Separately, HM Treasury proposed in March 2026 an absolute 10-year longstop on complaints to the ombudsman; when this page was last reviewed it was a proposal, not law. Under the FCA’s PS25/19, a single consolidated complaints return replaces five existing returns, with data collected from 1 January 2027 and the first period running from January to June 2027. In the US, the CFPB stopped publishing consumer complaint narratives in August 2026, though complaints still flow to companies through its portal.

Why Run Complaints Handling in CheckFlow?

1

The deadline is set on day one

Due-date offsets run from the received date, so the acknowledgement, the response and any dispute deadline land on the right people. The Tasks grid shows every open complaint, and analytics show what is overdue.

2

UK, US and dispute rules in one template

Conditional logic reads the jurisdiction and the dispute answer. A UK complaint gets the DISP steps; a US card dispute gets the Regulation Z timeline and the CFPB steps.

3

A file the ombudsman can follow

The outcome and any redress above the limit go to named people as approval tasks. Evidence and letters attach to the task they support, and the timestamped activity trail exports when the ombudsman or an examiner asks what happened and when.

CheckFlow is not a CRM, complaints case system or letter generator, and it does not submit responses to the CFPB portal. It runs the workflow around those tools: who does each step, by when, and who approved the outcome. Your CRM can start a checklist through the API, and the financial services overview shows other workflows regulated firms run the same way.

UK firms feed complaints MI into the board’s annual Consumer Duty assessment, which the Consumer Duty Annual Review Checklist covers. Complaint files are an early request in a supervisory visit, so pair this template with the Regulatory Examination Preparation Checklist, and see CheckFlow’s compliance checklist software for the wider compliance calendar.

Frequently Asked Questions

How long does a firm have to respond to a complaint under FCA rules?

+

For most complaints, eight weeks from receipt under DISP 1.6.2R. By then the firm must send a final response, or explain in writing why it cannot yet, when it expects to, and that the customer can now go to the Financial Ombudsman Service. Payment services and e-money complaints need a final response within 15 business days, or 35 in exceptional circumstances with a holding reply.

What is a summary resolution communication?

+

It is the written message a UK firm sends when it resolves a complaint by close of business on the third business day after receipt. It confirms the complaint is treated as resolved and tells the customer they can still refer it to the Financial Ombudsman Service. These complaints are exempt from the normal time limits but still count in complaints reporting.

When can a customer take a complaint to the Financial Ombudsman Service?

+

After the final response, or once the deadline passes without one. The customer normally has six months from the final response to refer it, and the complaint must also be brought within six years of the event or, if later, three years of when the customer knew or should have known they had cause to complain. The final response has to explain these rights and say whether the firm consents to the ombudsman looking at a complaint referred late.

How long do companies have to respond to CFPB complaints?

+

The CFPB asks companies to respond through its portal within 15 days. If more work is needed, the company can mark the response in progress and give a final response within 60 days, describing the steps taken and any remedy. The portal process runs alongside any statutory error resolution deadline, not instead of it.

Is a disputed card charge a complaint or an error dispute?

+

In the US it can be both. An unauthorised or incorrect electronic transfer reported within 60 days of the statement triggers Regulation E error resolution, and a credit card billing error notice triggers Regulation Z, each with its own deadlines. Log it as a complaint and run the dispute timeline in parallel, as Phase 2 does.

What should complaints root cause analysis include?

+

A root cause category for every complaint, a check of whether the same issue affects customers who have not complained, and corrective actions with owners and dates. UK rules require firms to identify and remedy recurring or systemic problems. Review the categories monthly so a rising trend reaches management before it reaches the regulator.
