Carillion has been appointed preferred bidder to provide facilities management services in public sector prisons.
One contract will be based in prisons in London and east of England and the second will provide services in prisons in the south west, south central, Kent and Sussex.
The contract is thought to be worth up to approximately £200m over five years.
The contracts cover approximately 50 prisons and will be for an initial five-year period, with the potential for two subsequent one-year extensions.
Carillion will provide a wide range of hard and soft facilities management services, including mechanical and electrical engineering maintenance, building fabric maintenance, energy and environmental services, waste management, escort services for contractors, cleaning services and minor building works.
Mobilisation is scheduled to begin in 2015, while the contract is due to begin 1 June 2015. The combined revenue from these two contracts is expected to be between £35m and £40m per year.
Commenting, Carillion Chief Executive, Richard Howson, said: "We are delighted to have been selected for these services contracts. I believe this reflects our ability to provide fully integrated service solutions that are tailored to the needs of our customers, combined with a strong focus on quality and value for money. We look forward to working closely with the Ministry of Justice to support its objectives of providing more efficient, high-quality services in public prisons."
