Site visit to new prison development, HMP Millsike

26 April 2023 , HMP Millsike, York
HMP Millsike │ Ministry of Justice

Join us for a visit to the construction site of Britain’s newest ‘smart’ prison, HMP Millsike, designed to house over 1,400 inmates which is being built by Kier opposite the existing HMP Full Sutton.

This visit is part of a rolling programme of Buildoffsite and CIRIA events, webinars and publications focussed on net zero carbon for different construction methods and materials.

Building work started last Autumn on the cutting-edge jail in East Yorkshire which will deliver over 1,400 modern places when it opens in 2025. Designed with security and rehabilitation in mind, the new Category C prison will be equipped with the latest smart technology.

It will also be the first new prison to operate as zero-carbon in the future, with an all-electric design, solar panels, heat pumps and more efficient lighting systems to reduce energy demand significantly.

The new buildings will sit opposite the existing HMP Full Sutton and will be the third of six prisons to be completed as part of the New Prisons Programme, following HMP Five Wells and HMP Fosse Way in Glen Parva, which is due to open this year.
