According to ONS data from April 2025, 18 per cent of all adults in the UK suffered moderate to severe depressive symptoms.
Figures from the Priory Group suggest that, in any given week, one in six adults in the UK experiences a common mental health problem, such as depression or anxiety. And the British Medical Association states that “The estimation* of the prevalence of common mental disorders (for example, anxiety or depression) amongst adults aged 16-64, for example, had risen from 17.6 per cent in 2007 to 22.6 per cent in 2023/4,” based on the latest information available.
