HMP Hewell was established in June 2008 following the amalgamation of three former prisons on the site – Blakenhurst, Brockhill and Hewell Grange. Each site catered for a different category of prisoner – categories B, C and D. In 2011, house block 7, the category C section (formerly Brockhill)), was closed.
Remaining were the house blocks 1-6 on the closed site (formerly Blakenhurst) and house block 8 (formerly Hewell Grange), also known as the Grange Resettlement Unit or the open site. The prison primarily serves the Gloucestershire, Worcestershire, West Midlands and Warwickshire catchment area and is part of the West Midlands Region. It has a capacity for 900 inmates on the closed site, and 225 on the open site. The #1 governor is Clare Pearson, who has been in post since February 2019
The six house blocks have single and double cells, all with in-cell sanitation.
- House blocks 1, 2 A&C spur and 6 – convicted and unconvicted prisoners
- House block 3 – induction/first night unit
- House block 4 – prisoners with drug or alcohol issues
- House block 5, 2B spur – vulnerable prisoners
