What Is High Down Prison Like?
Last reviewed: July 2026
High Down sits on the Surrey downs near Banstead, on the site of the old Banstead hospital. For most of its life it worked as a local prison for south London courts — busy, crowded and transient. In recent years it has moved to a Category C training and resettlement role, but the population pressure of the London estate means the reality is somewhere between the two: many men still arrive early in their sentence, before they are settled or ready for a training regime.

What inspectors have said
The last full HMIP inspection (2023) raised eleven concerns, four of them priorities: acutely mentally unwell men held in segregation, widespread illicit drugs with one of the highest positive test rates in the male estate, rising violence linked to drugs and debt, and too little full-time purposeful activity. A follow-up progress review in 2024 found some good work but drug availability and violence still stubborn. The Independent Monitoring Board has also noted that population pressure sends men to High Down before they are ready for a Cat C regime. Reports are on the HMIP website and IMB website.
Daily life at High Down
Modern accommodation by prison standards (it opened in 1992), mostly shared cells across six houseblocks. Work, education and training places exist but not enough for everyone full-time, so expect some banged-up afternoons. The standout opportunity is The Clink — a real restaurant open to the public where selected prisoners train for City & Guilds catering qualifications, with strong job prospects on release. Progression to Category D open conditions, or release on Home Detention Curfew, depends on engagement and clean behaviour — which matters even more under the Sentencing Act 2026 earned-progression rules.
From first-hand experience — Prison Guide’s founder Daniel Hockey served a sentence himself, from HMP Wandsworth through to open conditions at HMP Ford, and wrote The Secret Prisoner (2021) — large south-east prisons run on routine: get a job or education place as early as you can, keep away from borrowed vapes and canteen debt, and time moves much faster. Our first night in prison guide covers the early days.
Visiting High Down
Social visits run on Tuesday and Wednesday (9–11am and 2–4pm, by houseblock) and weekend afternoons (2–4pm). Book ahead, bring accepted photo ID, and check the dress code before travelling — High Down publishes a strict one.

Details on the GOV.UK High Down page; national rules in our visiting guide, and here is how to send money to a prisoner.
• “High Down is still a Category B local” — it has been re-roled to Category C, though it still takes men early in their sentences due to population pressure.
• “The Clink is a myth or a one-off event” — it is a real public restaurant at the prison and has operated for years, training prisoners for hospitality careers.
• “You can visit any day” — visits run only on Tuesdays, Wednesdays and weekends; always book first.
• “Cat C means men are nearly free” — it is a closed prison; open conditions come later, at Category D.
