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. The acting #1 governor is Jane Bailey.
