Contractor ISG has been appointed to the Ministry of Justice's (MoJ) five-year, £2.5 billion Constructor Services Framework.

The firm has has also been awarded its single largest refurbishment project to date, a £61 million upgrade scheme at HMP Birmingham.

Through the Constructor Services Framework, ISG secured the maximum number of lots achievable, providing access to national and regional MoJ opportunities for projects valued up to £30 million. The framework encompasses new build, alterations, refurbishment and maintenance requirements across the entire MoJ UK estate.


ISG's major refurbishment project at HMP Birmingham is part of the MoJ’s wider £3.8 billion estate modernisation programme, which sees the creation of 20,000 new prison places across the UK. As part of this, ISG will refurbish and return to use 300 single person cells at HMP Birmingham - a Category B men’s prison in the Winson Green area of the city.

ISG is also one of four project partners on the MoJ's pioneering £1 billion New Prisons Programme Alliance. This high-profile programme sees four of the UK’s top Tier 1 contractors working together collaboratively to deliver four new adult male prisons across the UK, in a novel procurement approach that is being widely held up as an exemplar for unlocking innovation and learning, promoting efficiencies and best value, while focusing on optimum sustainable and social value outcomes.
