WHAT CAUSES HOMELESSNESS: LOOKING BENEATH THE HOUSING CRISIS

Homelessness is a housing issue. A shortage of affordable homes, rising living costs, poverty and insecure tenancies can all push people into crisis. But losing a home rarely happens in isolation. For many people, homelessness is connected to trauma, poor mental health, addiction and complex needs; experiences that can make it much harder to find, secure and sustain a safe home.

Understanding those connections matters. If we look only at the moment someone loses their accommodation, we risk missing what has happened to them before, what they experience while homeless and what support they may need to move forward.

Homelessness and trauma can reinforce one another

Trauma may be present long before someone becomes homeless. Abuse, neglect, bereavement, family breakdown, poverty and damaging experiences of education or public services can all have lasting effects.

Evidence suggests that up to 94% of people facing homelessness in England have experienced trauma, with two in three reporting four or more traumatic events or prolonged experiences. Homelessness can then create further trauma through instability, isolation, violence and the daily stress of not having a place to call home.

This means some people are living not with one traumatic experience, but with layers of compounded trauma. Homelessness is therefore not simply the loss of a house. but can be both a consequence and a cause of profound harm.

Mental health, homelessness and housing insecurity

Poor mental health can increase someone’s risk of homelessness. It may affect their ability to work, manage money, maintain relationships, navigate services or cope with a sudden change in circumstances.

At the same time, homelessness can cause or intensify mental ill health. UK estimates suggest that around 45% to 82% of people experiencing homelessness have a diagnosed mental health condition, while as many as 80% of people sleeping rough experience poor mental health.

Without timely, accessible support, a person can become trapped in a cycle: poor mental health makes housing harder to sustain, while housing insecurity further damages their wellbeing.

Addiction is often a response to trauma, not a reason to withdraw support

There is a persistent assumption that alcohol or drug use is simply a cause of homelessness – and worse, that it makes someone less deserving of help.

The reality is more complex. Substance use may begin or increase as a way of coping with trauma, distress, poor mental health or the experience of sleeping rough. Around 45% of people experiencing homelessness who use drugs or alcohol report doing so to cope with mental health difficulties or past trauma.

Mental health and substance use also frequently overlap. More than 42% of people experiencing homelessness are reported to have both a mental health condition and a substance use disorder. Treating either issue in isolation may therefore leave the person without the joined-up support they need.

Addiction should not be treated as a moral failing. It is often connected to experiences that require understanding, specialist help and compassion.

A set of keys is a beginning, not the end

Providing a safe, affordable home is essential, but housing alone may not resolve everything that has contributed to someone’s homelessness.

Four walls do not automatically feel like a home. Someone moving into accommodation may have few belongings, no basic household essentials and limited support. They may be coping with trauma, debt, isolation or unfamiliar responsibilities. Previous experiences of being let down by services can also make it difficult to ask for or trust help.

Without person-centred support, people can become overwhelmed, fall into arrears or face homelessness again. This is not evidence that they have “failed” a tenancy. It shows why preventing homelessness requires more than responding to the immediate housing emergency.

Breaking the cycle

There is no single cause of homelessness and no single solution. We need enough genuinely affordable homes, alongside early intervention and properly funded mental health, addiction and trauma-informed services. Support must be compassionate, consistent and shaped around the individual rather than expecting the individual to fit a fragmented system.

At Hopestead, we believe everyone deserves a place to call home. Adverse life experiences can stack the deck against someone, but they should never determine what that person deserves.

No one is undeserving of a home, support and the opportunity to thrive. When we look beyond judgement and understand what sits beneath a housing crisis, we can help prevent homelessness rather than waiting for it to happen, and give people a genuine opportunity to rebuild their lives.
