Vulnerable Customer Complaints: Meeting Enhanced Duty Requirements

Structured processes ensure complaints from vulnerable customers receive the enhanced care, flexibility, and support that the FCA expects under its vulnerability guidance and the Consumer Duty.

Vulnerable Customers Face Additional Barriers When Complaining

47%
of UK adults display one or more characteristics of vulnerability
FCA Financial Lives Survey 2022

The FCA's guidance on the fair treatment of vulnerable customers (FG21/1) makes clear that vulnerability is not a fixed state but a spectrum that can affect anyone at any time. Health conditions, life events, financial difficulty, and low capability can all create vulnerability that makes it harder for customers to navigate the complaints process, articulate their concerns, and achieve fair outcomes.

Standard complaints handling processes are often designed around the assumption that the complainant can engage effectively: reading correspondence, meeting deadlines, providing information on request, and making informed decisions about outcomes. For vulnerable customers, these assumptions may not hold. Without proactive adjustments, firms risk compounding the harm that led to the complaint in the first place.

Under the Consumer Duty, firms must act to deliver good outcomes for all customers, with a particular focus on those who are vulnerable. This means complaints handling processes must be flexible enough to accommodate different needs, and handlers must be trained to identify vulnerability signals and respond appropriately.

Vulnerability-Aware Complaints Handling Workflows

A vulnerability-aware complaints process does not mean creating a separate complaints track for vulnerable customers. It means building flexibility, identification triggers, and enhanced support options into your existing workflow so that every complaint interaction can be adapted to the customer's needs.

Automated vulnerability flags, triggered by keyword detection in correspondence or handler observation, ensure that identified vulnerabilities are visible throughout the complaint journey. These flags activate enhanced process requirements: more frequent contact, alternative communication formats, extended response times where appropriate, and mandatory management oversight.

Comprehensive training, supported by structured decision frameworks, gives handlers the confidence and tools to identify vulnerability, adjust their approach, and document the additional steps taken. This documentation is essential both for demonstrating compliance to the FCA and for ensuring continuity if the complaint is transferred between handlers.

Implementing Vulnerability-Aware Complaints Handling

These steps will help you build a complaints process that identifies vulnerability early and adapts to deliver fair outcomes for all customers.

1

Establish vulnerability identification triggers

Define the signals that should prompt handlers to consider whether a complainant may be vulnerable. These include direct disclosure, emotional distress during calls, inconsistent or confused communication, references to health conditions or bereavements, financial hardship indicators, and language or literacy barriers. Build these triggers into your complaint intake process.

Use a simple screening prompt at the complaint acknowledgement stage that asks handlers to consider whether any vulnerability factors have been identified, rather than relying on customers to self-declare.
2

Create a vulnerability assessment framework

When vulnerability is identified, the handler should conduct a proportionate assessment to understand the nature and impact of the vulnerability on the customer's ability to engage with the complaints process. This is not a clinical assessment but a practical evaluation of what adjustments may help: Does the customer need information in a different format? Do they need more time? Would they benefit from a single point of contact?

3

Configure enhanced workflow requirements

When a complaint is flagged as involving a vulnerable customer, activate enhanced workflow steps: mandatory call-back within 24 hours of identification, single named handler assignment, reduced internal deadlines to allow more time for customer engagement, and mandatory team leader review before the final response is issued.

Create different enhancement levels (standard, enhanced, critical) to match the severity and impact of the identified vulnerability without over-engineering the process for every case.
4

Capture and apply communication preferences

Record the customer's preferred communication method, format, and timing. Some vulnerable customers may need large print correspondence, phone calls instead of letters, communications addressed through a representative, or contact at specific times. Ensure these preferences are visible to everyone who interacts with the complaint and are applied consistently.

5

Train handlers in vulnerability awareness

Deliver comprehensive training covering the FCA's vulnerability guidance (FG21/1), the Consumer Duty expectations, practical identification techniques, and communication skills for engaging with vulnerable customers. Training should include scenario-based exercises and be refreshed annually.

6

Document all adjustments and their rationale

Record every adjustment made in response to identified vulnerability: what was identified, what action was taken, why, and what the outcome was. This documentation demonstrates compliance, supports continuity across handler changes, and provides evidence for FOS cases and regulatory reporting.

7

Monitor outcomes for vulnerable complainants

Track complaint outcomes segmented by vulnerability status. Compare resolution times, upheld rates, customer satisfaction, and FOS referral rates for vulnerable vs non-vulnerable complainants. Any material differences may indicate that your process adjustments are insufficient or that vulnerable customers are not receiving equitable outcomes.

8

Report vulnerability data to governance forums

Include vulnerability complaint data in your regular complaints MI reporting. The board and senior management should have visibility of the volume and nature of vulnerable customer complaints, the adjustments being made, and the outcomes being achieved. This supports Consumer Duty governance requirements.

Best Practices

Avoid labelling customers as "vulnerable"

Focus on identifying characteristics of vulnerability and the specific needs they create, rather than categorising individuals. A customer experiencing bereavement may need additional time and empathy but may be fully capable of engaging with the process in all other respects. Tailor your response to the specific need.

Recognise that vulnerability can be transient

A customer who is vulnerable at the start of the complaints process may not be by the end, and vice versa. Build regular check-in points into your workflow where handlers reassess the customer's needs and adjust the approach accordingly.

Provide handler wellbeing support

Handling complaints from vulnerable customers, particularly those involving bereavement, serious illness, or financial distress, can be emotionally demanding. Ensure handlers have access to supervision, peer support, and employee assistance programmes. Handler wellbeing directly impacts the quality of customer interactions.

Engage specialist support where appropriate

For complaints involving complex vulnerability factors such as mental health conditions, cognitive impairment, or domestic abuse, consider whether specialist input would help you handle the complaint more effectively. This might include consulting with occupational health, engaging a specialist advocacy service, or seeking legal advice on capacity issues.

Use positive friction to prevent harm

Sometimes the best adjustment is to slow down the process to prevent the customer from making a decision they may later regret. If a vulnerable customer is pressing to accept a settlement that appears inadequate, a managed pause with clear explanation can protect their interests without being paternalistic.
