The FCA expects every regulated firm to handle complaints fairly, thoroughly and promptly. But effective complaints management goes far beyond meeting DISP timescales. It is one of the clearest signals of whether your firm is delivering good outcomes for customers
At Square 4, we help financial services firms build complaints frameworks that not only ensure compliance, but also deliver deep, actionable insight to aid decision making. We help our clients reduce regulatory risk and strengthen their businesses. Our team brings direct experience from both sides of the regulatory relationship. We have designed, implemented and reviewed complaints frameworks across banking, insurance, wealth management, pensions and consumer credit, and we understand what the FCA expects when it looks at how you handle complaints.

Why Complaints Management Is a Regulatory Priority
Under DISP, firms must identify, log, investigate and resolve complaints within defined timescales, and report complaints data to the regulator annually.
However, as well as looking for technical compliance, recent FCA reviews have highlighted a number of thematic challenges:
The introduction of Consumer Duty has raised the bar further. Complaints are now a primary source of evidence for whether your firm is delivering good outcomes across the four outcome areas: products and services, price and value, consumer understanding and consumer support. High volumes, recurring themes or complaints from vulnerable customers can all signal the need to reflect on your approach.
The risks of ineffective complaint handling include s166 skilled person reviews and, potentially, significant remediation costs.
Root Cause Analysis Methodology
Our root cause analysis uses a multi-layered methodology that identifies immediate causes (what went wrong), underlying causes (why it went wrong) and systemic causes (what broader failures allowed it to happen). We analyse complaints populations thematically, identifying patterns across products, channels and customer segments. The output is a prioritised action plan linked to specific process, product or communication changes.
The FCA has repeatedly observed complaints being categorised as admin or staff errors without firms investigating the systems, processes or knowledge gaps that caused them. Our methodology addresses this directly, delivering the depth of analysis regulators expect.
We were recipients of the ICA’s Compliance Consultancy of the Year Award in 2024 for our design and embedding of an outcomes monitoring framework for a digital bank, which included their approach to identifying the root cause of complaints.
MI & Board Reporting Design
We design complaints MI that gives your board genuine insight, not just data. This includes executive-level dashboards with key performance indicators, trend analysis with early warning indicators, segmentation by product, channel and customer demographic, Financial Ombudsman Service referral and uphold rate tracking, and vulnerable customer complaints monitoring. Our MI frameworks are designed to support Consumer Duty board assessments and SM&CR accountability requirements.
Complaints Framework Design
Bespoke framework design covering the full complaints lifecycle: complaints definition and identification procedures, investigation and resolution quality standards, root cause analysis, governance structures and escalation routes, MI dashboard design and KPIs, quality assurance and risk management. We deliver comprehensive process and policy design, complaints training materials and a governance framework ready for implementation.
Complaints Quality Assurance & Health Checks
Independent assessment of your complaints handling effectiveness. We conduct sample file reviews assessing response quality, fairness and timeliness, DISP compliance gap analysis, root cause analysis assessment, MI adequacy evaluation and governance effectiveness review. We benchmark your framework against FCA expectations and industry best practice, providing a prioritised improvement roadmap. Ideal for firms seeking independent assurance or preparing for regulatory review.
Complaints Handling Outsource
We deliver longer-term managed solutions which ringfence (or partially ringfence) complaints handling while improving efficiency over time and delivering the benefits to you. This includes expert staff, support services, oversight and governance, automation and AI driven solutions, full root cause analysis, MI reporting, governance and open, pragmatic relationship management. We also offer hybrid models combining your teams with our specialists (‘model office’ or ‘champion / challenger’), and surge capacity during peak periods.
Training & Capability Building
We design and deliver training programmes covering complaints handling for front-line and back-office teams, root cause analysis for MI and quality assurance teams, DISP compliance, fair outcomes assessment and vulnerable customer complaints handling. We offer both workshop-based and train-the-trainer models to build lasting internal capability.
Complaints Handling Resource
We provide experienced Complaint Handlers, QA, Team and Operations Managers who work under your direction and processes to investigate and resolve complaints to FCA standards.
Vulnerable Customers and Complaints
The FCA expects enhanced complaints handling for vulnerable customers, aligned with FG21/1. This means training complaints handlers to spot vulnerability indicators, tailoring communication approaches, allowing additional time for responses and considering whether vulnerability contributed to the issue. Complaints from vulnerable customers should be tracked as a distinct category in your MI, with trends reported to board and governance committees.
Financial Ombudsman Service Management
High FOS referral and uphold rates attract high costs, and indicate the need to evaluate your complaints process.. Firms should track FOS data as core MI, learn from FOS decisions and incorporate findings into their complaints framework, products and servicing approach, and ensure complete file documentation to support any FOS review. Reducing FOS referrals through fair first-time handling is both a regulatory expectation and a cost-saving measure.

Square 4 was named Compliance Consultancy Firm of the Year 2024 by the International Compliance Association - recognised for delivering measurable improvements in regulatory compliance and customer outcomes. Our complaints team combines former FCA supervisors with senior practitioners who have designed and reviewed frameworks across every regulated financial services sector.
Our team includes professionals who have worked within FCA supervision and enforcement (some for over 20 years).

This insight shapes every framework we design and every health check we deliver.
We focus on actionable insight. Our root cause analysis methodology and MI frameworks are designed to drive genuine business improvement - reducing complaints volumes, lowering FOS referral rates and preventing the systemic issues that lead to costly remediation programmes.
What are the FCA’s key requirements for complaints handling?
The FCA’s DISP rules require firms to identify and log all complaints (including expressions of dissatisfaction), investigate them fairly and promptly, issue final responses within eight weeks, maintain records for at least three years, and report complaints data annually. Firms must also have clear procedures, trained staff and appropriate governance. Beyond DISP compliance, the FCA expects firms to conduct meaningful root cause analysis, identify systemic issues and use complaints data to evidence Consumer Duty outcomes. Square 4 helps firms meet these requirements while delivering quality outcomes.
How do complaints relate to Consumer Duty?
Complaints are a primary indicator of whether your firm is delivering the good outcomes required under Consumer Duty. The FCA expects firms to use complaints data as part of their outcomes monitoring framework, identifying where products, services or communications are failing across the four outcome areas. High volumes, recurring themes or complaints from vulnerable customers may signal poor outcomes that require investigation and remediation. Complaints data should feed into your annual Consumer Duty board assessment.
Can Square 4 handle complaints on our behalf?
