Costain has won a bid to provide strategic advisory services to the Department for Energy Security & Net Zero (DESNZ) as part of its Energy and Net Zero Professional Services Framework.

Under the agreement, Costain will deliver technical expertise and advisory services for two key areas of the framework: Nuclear and Emerging Technologies. The company’s role could include advising on the adoption of innovative technologies aimed at facilitating the UK's transition to cleaner energy. This may encompass emerging and modular nuclear technologies, including small modular reactors (SMRs), as well as other net-zero solutions, depending on the department's evolving needs.


Costain is among 43 suppliers selected for the Framework, which has a total value of £250 million and an initial duration of two years, with the option to extend for an additional two years.

Costain will lean on its cross-sector and multi-disciplinary expertise in nuclear energy and clean energy projects to advise DESNZ on its complex energy security and net zero challenges. Costain's staff and engineers will provide technical expertise across three service deliverables: Policy and Strategy, Energy Design and Delivery, and Enterprise and Innovation.
