Vulnerable Customer Detection: AI-Powered Protection for FCA Consumer Duty
The FCA Consumer Duty Vulnerability Challenge
The FCA Consumer Duty, effective July 2023, fundamentally changed how financial services firms must treat customers. At its core is a simple but profound requirement: firms must deliver good outcomes for all customers, including those in vulnerable circumstances.
But here's the problem: vulnerability isn't a demographic category. It's not age, income, or education level. Vulnerability is situational, temporary, and often invisible until the critical moment when a customer needs protection most.
The FCA's definition of vulnerability encompasses:
- Health: Physical disability, mental health conditions, severe illness
- Life Events: Bereavement, job loss, relationship breakdown, caring responsibilities
- Resilience: Low income, over-indebtedness, limited savings buffers
- Capability: Low financial literacy, learning difficulties, English as second language, digital exclusion
The scale: FCA research indicates 50%+ of UK adults have characteristics of vulnerability at any given time. Traditional call centre monitoring cannot identify these customers reliably—but AI can.
Why Manual Monitoring Fails Vulnerable Customer Detection
The 3% Sampling Problem
If you're only reviewing 3-5% of calls, you're missing 95% of vulnerable customer interactions. Even if your compliance officers are excellent at identifying vulnerability during their limited reviews, they can't protect customers in the calls they never hear.
⚠️ THE VULNERABILITY DETECTION GAP:
Scenario: 100-seat call centre, 500,000 annual calls, 25% involve vulnerable customers (125,000 interactions)
- Manual 3% Sampling: Reviews 15,000 calls, identifies ~3,750 vulnerable interactions
- Vulnerable Customers Undetected: 121,250 (97%)
- Regulatory Risk: Massive—firm cannot demonstrate good outcomes for majority of vulnerable customers
- FCA View: "Sampling-based approaches are insufficient for Consumer Duty compliance"
The Real-Time Detection Imperative
The critical moment: A vulnerable customer indicates confusion or distress during a product sale. This is when protection is needed—not 5 days later during a compliance review.
Manual Monitoring Timeline:
- Day 0: Vulnerable customer confused about high-risk investment, proceeds with purchase
- Day 5: Compliance officer reviews call (if randomly selected)
- Day 6: Vulnerability indicators identified retrospectively
- Day 7: Customer remediation begins—but unsuitable product already sold
- Result: Customer harm occurred despite eventual detection
AI Real-Time Detection:
- Minute 0-15: AI monitors call continuously
- Minute 15: Customer says "I'm not sure I understand the risks..."
- Minute 15:05: AI detects vulnerability indicators (comprehension difficulty)
- Minute 15:10: Supervisor receives alert + call context
- Minute 15:30: Supervisor joins call, provides additional explanation
- Minute 20: Sale proceeds only after customer demonstrates full understanding
- Result: Vulnerable customer protected in real-time, good outcome achieved
How AI Detects Vulnerability: The Technical Approach
Regulativ's Multi-Dimensional Vulnerability Detection
Human vulnerability is complex and multi-faceted. Regulativ's AI analyzes multiple indicators simultaneously to identify customers needing extra support:
✅ REGULATIV VULNERABILITY INDICATORS (30+ Signals):
1. Comprehension Difficulty Indicators
- "I don't understand..." - Direct admission of confusion
- Repeated questions - Customer asks same question multiple times
- Long pauses - Extended silence after agent explanations (7+ seconds)
- Misunderstanding key terms - "What's an APR?" / "What does compound mean?"
- Asking for simpler explanations - "Can you explain that in plain English?"
2. Emotional Distress Signals
- Crying or voice breaking - Vocal emotion detection via tone analysis
- Stress in voice - Increased pitch, rapid speech, trembling
- Expressions of anxiety - "I'm really worried about..." / "I'm stressed about..."
- Panic indicators - "I don't know what to do" / "I'm desperate"
- Life event mentions - Recent bereavement, job loss, illness
3. Financial Resilience Red Flags
- Debt discussions - "I'm behind on my bills" / "I have debts I can't pay"
- Financial pressure - "I really need this money now" / "I can't afford to lose anything"
- Dependency on product - "This is all the money I have" / "I need the income from this"
- Affordability concerns - "I'm not sure I can afford the fees..."
4. Capability and Literacy Indicators
- Reading difficulty - "I can't read the small print" / "Can you read it to me?"
- Digital exclusion - "I don't use computers" / "I don't have email"
- Reliance on others - "My son usually helps me with this"
- Age-related capability - Combined with other indicators, not age alone
5. Agent Behavior Red Flags
- Dismissive responses - "Don't worry about it" / "It's not complicated"
- Rushed explanations - Fast talking, skipping details
- Pressure tactics - "This offer expires today" / "You need to decide now"
- Incomplete disclosures - Skipping risk warnings when customer seems confused
Sentiment Analysis: Beyond Words
Regulativ's AI doesn't just analyze what customers say—it analyzes how they say it. Tone, pitch, speed, and emotional content reveal vulnerability even when words don't:
Vocal Emotion Detection:
- Stress Analysis: Increased pitch + rapid speech = anxiety indicator
- Uncertainty Detection: Hesitation, filler words ("um", "uh"), questioning intonation
- Sadness/Depression: Flat affect, slow speech, low energy
- Confusion: Rising intonation on statements (should be falling), repeated clarifications

Specific Protection Examples
Example 1: Bereavement-Related Vulnerability
- Detection: Customer mentioned husband's recent death, asked about consolidating accounts
- AI Alert: Life event vulnerability detected + financial decision under emotional distress
- Action: Agent offered to schedule follow-up call in 2 weeks, provided bereavement support resources
- Outcome: Customer appreciated consideration, returned when emotionally ready, became loyal customer
Example 2: Comprehension Difficulty
- Detection: Customer asked "What's compound interest?" three times during savings product call
- AI Alert: Repeated comprehension difficulty + key financial concept misunderstood
- Action: Supervisor joined call, used simpler explanations and visual materials (sent via email)
- Outcome: Customer fully understood product before proceeding, provided positive feedback
Example 3: Financial Pressure Unsuitable Sale Prevention
- Detection: Customer said "I need income from this, it's all I have" during high-risk investment call
- AI Alert: Critical vulnerability + dependency on capital + high-risk product = unsuitable
- Action: Supervisor intervened, recommended lower-risk income product instead
- Outcome: £45,000 investment redirected to appropriate product, regulatory violation prevented
Automated Protective Workflows
Real-Time Escalation Rules
Regulativ allows firms to configure automatic protective responses based on vulnerability detection:
📋 AUTOMATED PROTECTION WORKFLOWS:
Level 1: Agent Guidance
- Trigger: Mild vulnerability indicators (single comprehension question)
- Action: Pop-up reminder to agent: "Customer may need extra explanation"
- Agent Response: Slow down, use simpler language, check understanding
Level 2: Supervisor Alert
- Trigger: Moderate vulnerability (multiple indicators, emotional distress)
- Action: Alert sent to supervisor with call link and transcript excerpt
- Supervisor Action: Listen to call, decide whether to intervene or monitor
Level 3: Immediate Intervention
- Trigger: Severe vulnerability (customer distress + high-risk product + financial pressure)
- Action: Critical alert + supervisor auto-joins call (whisper mode)
- Supervisor Action: Take over call or provide real-time guidance to agent
Level 4: Specialist Routing
- Trigger: Complex vulnerability (mental health, severe capability issues)
- Action: Call automatically transferred to specialist vulnerable customer team
- Specialist Action: Trained experts handle sensitive situation with appropriate support
Post-Call Protective Actions
For vulnerabilities detected during calls (even if no immediate intervention occurred), Regulativ triggers follow-up workflows:
- Account Flagging: Customer record marked as "vulnerable" for future interactions
- Follow-Up Calls: Automated scheduling of check-in calls 24-48 hours later
- Enhanced Cooling-Off: Extended cancellation periods for vulnerable customers
- Transaction Review: Compliance review of all sales to flagged customers
- Targeted Communications: Large print, simple language, accessible formats
