What The Grenfell Tower Tragedy Teaches Us About Psychological Safety

A few weeks ago, I attended the Festival of Work in London and had a brief conversation with Shaun Lundy, IOSH President Elect and Chair of the IOSH Construction Committee, after his session ‘Safe to Stay’ on psychological safety.
Shaun recommended that I read the findings of the Grenfell Tower Inquiry. His reason was simple: while Grenfell is remembered as one of the UK's worst modern disasters, it also provides a stark example of what can happen when people feel unable to speak up - or when those who do are not heard.
The Grenfell Tower fire tragically claimed 72 lives. The Inquiry uncovered a series of failures spanning many years, involving multiple organisations, government departments and jurisdictions. While technical, regulatory and governance failures all played a part, a recurring theme throughout the findings was that concerns were raised repeatedly but were too often ignored, dismissed or not acted upon.
For anyone interested in leadership, culture and psychological safety, there are important lessons to be learned from this tragedy.
The Human Cost of Poor Psychological Safety
Psychological safety is often described as an environment where people feel able to speak openly, raise concerns, challenge decisions and share difficult information without fear of negative consequences. However, psychological safety is not simply about creating opportunities for people to speak up. It is also about ensuring that concerns are listened to, taken seriously and acted upon promptly and fairly.
The Grenfell Inquiry revealed multiple examples of warnings being raised over many years. Residents voiced concerns about safety. Professionals and experts identified risks. Questions were asked, concerns were escalated, and opportunities existed to intervene. Yet the system repeatedly failed to respond effectively.
One of the Inquiry's most striking conclusions related to organisational culture. The report stated:
"The culture did not allow for concerns to be raised and frank advice to be given to ministers, and there was an unwillingness to accept external scrutiny and challenge."
That observation should give every leader pause for thought.
Speaking Up Is Only Half the Equation
Many organisations have invested heavily in encouraging employees to speak up. They have introduced whistleblowing procedures, reporting systems, open-door policies and employee engagement initiatives. All very important steps to building a positive working environment.
However, Grenfell highlights a crucial truth: speaking up is only half of the equation. If concerns disappear into bureaucracy, if difficult messages are ignored, or if challenges are viewed as inconvenient rather than valuable, then psychological safety does not truly exist.
People quickly learn whether their voice matters. When concerns are repeatedly dismissed, individuals become less likely to raise them again. Over time, silence becomes normal, and risks remain hidden until it is too late.
This aligns closely with findings from my own research within professional services firms. When psychological safety is low, the decision not to speak up can have significant consequences for both individuals and organisations.

Employees may experience frustration, anxiety and, in some cases, depression when they feel unable to raise concerns or challenge decisions.
In organisations where authority is closely linked to position and hierarchy, there can also be a tendency for those lower down the hierarchy to remain silent because they assume that those at the top have the experience to know what is best. While respect for experience is important, not challenging authority can prevent valuable insights, concerns and warnings from being shared when they are needed most.
The Cost of Not Listening
Major disasters are rarely caused by a single mistake. More often, they result from a series of missed opportunities, signals ignored and decisions that, individually, may seem insignificant but collectively create the conditions for failure. The Grenfell Inquiry paints a picture of exactly this type of systemic breakdown.
As organisational leaders, it prompts us to ask some uncomfortable but necessary questions:
- Who in our organisation is trying to tell us something we may not want to hear?
- Are concerns being escalated effectively?
- Do people believe raising issues will lead to meaningful action?
- How do we respond when someone challenges our thinking?
- Are we rewarding agreement more than honesty?
The answers to these questions reveal far more about an organisation's culture than any policy document ever could.
A Positive Step Forward
One of the changes arising from the Inquiry is the government's commitment to strengthen whistleblowing arrangements within the Ministry of Housing, Communities and Local Government. This includes providing workers with routes to report certain types of wrongdoing and offering the option to raise concerns anonymously through external channels.
However, reporting systems alone cannot create psychological safety. The real challenge is cultural.
Leaders must create environments where concerns are actively sought out, where challenge is welcomed and where people trust that their voices will be heard.
The Leadership Lesson
The Grenfell Tower tragedy had many causes. One lesson runs consistently through the findings: concerns were raised, but too often they failed to result in meaningful action. For leaders, that may be the most important takeaway of all.
Psychological safety is not measured by how easy it is to speak up. It is measured by how seriously people are listened to when they do. Because being heard but not acted on can be just as dangerous as not being heard at all. Sadly, in the case of Grenfell Tower, many lives depend on it.
