Complaints are the insight source most firms rely on first. But if complaints data is the only lens you are using to understand vulnerable customers, you are seeing a fraction of the picture.
Most organisations track complaints. Many report on them regularly. Some even break them down by customer segment, including vulnerability. On the surface, this looks like a firm that is listening to its vulnerable customers.
But complaints data has a fundamental limitation. It only captures the experience of customers who complained. And for vulnerable customers, the decision to complain is itself shaped by the very circumstances that make them vulnerable.
The customers who do not complain
A customer dealing with a bereavement may not have the energy to raise a formal complaint about a process that added unnecessary friction to an already difficult moment. A customer with a cognitive impairment may not recognise that the service they received was below the standard they should expect. A customer in financial difficulty may be too anxious about the outcome of their case to risk drawing attention to how it was handled.
These are not edge cases. They are the everyday reality for a significant proportion of your customer base. If your vulnerability risk management relies primarily on complaints, you are measuring the visible surface of a much deeper issue.
Regulators expect firms to actively monitor customer outcomes, rather than waiting for customers to report poor ones. For vulnerable customers, this distinction matters. The absence of complaints is not evidence of good outcomes. It may be evidence that the customers most affected are the least likely to tell you.
Solicited and unsolicited insights
Complaints are one source of insight. But understanding what is really happening in vulnerable customer journeys requires a broader view. We think of customer insight as falling into two categories: solicited and unsolicited.
Unsolicited insights are the signals that arrive without being asked for. Complaints sit here, but so do social media mentions, call reasons, repeat contact patterns, journey abandonment data, and the observations colleagues share informally every day. Most firms collect this data. Few connect it to vulnerability in a structured way.
Solicited insights are the ones you go looking for. Lived experience discovery with vulnerable customers. Colleague interviews and workshops. Vulnerable customer journey mapping designed to surface what the standard MI does not capture. These are the insights that reveal why things are happening, not just what is happening.
When you combine both, you get a vulnerability gap analysis that complaints data alone could never provide. You see where the customer journey works, where it fails, and crucially, where the failure is invisible to your existing reporting.
What the data is trying to tell you
In our experience, the most revealing data points are rarely in the complaints MI. They are in the patterns that sit just beneath it. Repeat contacts where a vulnerable customer calls back three times because the first interaction did not resolve their need. Journey abandonment where a customer starts a process, hits a barrier, and quietly drops out. Escalations where a colleague knows the standard process will not work for this customer but has no supported alternative.
These patterns are signals that conduct risk is building. They tell you that the journey was not designed for the customer in front of it. They point to exactly where foreseeable harm sits, often long before that harm shows up as a complaint.
From data to action
The firms that use insight well do not just collect more data. They connect it differently. They build a picture of the vulnerable customer experience from multiple angles: what customers say, what colleagues see, and what the data reveals. They use that picture to improve outcomes for vulnerable customers, not just to report on them.
This matters for colleagues as much as customers. When frontline teams can see that the data they record and the feedback they share is leading to tangible change in how vulnerable customers are served, they engage differently. The insight becomes a tool for improvement, not just a reporting requirement.
A customer vulnerability audit that draws on the full range of solicited and unsolicited insights gives you something complaints alone never will: a view of the experience your vulnerable customers are actually having, including the ones who never told you it was not good enough.
