Expanding capacity while supporting rehabilitation

Wates Construction South is delivering the £119 million expansion of HMP Erlestoke in Wiltshire, in partnership with the Ministry of Justice as part of the Small Secure Houseblocks Programme.

The development will provide 180 additional category C prison places, alongside a new vocational training workshop and upgrades to existing facilities.

Designed to support rehabilitation, the scheme is creating modern, secure environments that enable education, skills development and positive outcomes for prisoners.
