A new report is commending High Down Men’s Prison in Banstead for the improvements it’s made over the last 3 years.

HM Inspectorate of Prisons says it has become “more robust” in its response to a recognised drugs problem.

Positive random drug tests have dropped from 31% during its 2023 audit to 19%.

But inspectors say drugs are still “the biggest threat to the stability of the prison” and keeping them out remains a “significant challenge”.
