Laing O’Rourke welcomes Government’s commitment to Sizewell C
22.07.25Laing O’Rourke has welcomed today’s announcement by the UK Government that it has reached a Final Investment Decision on Sizewell C.
This is a major step forward and builds on the progress the project has already made.
In June, the UK Government confirmed it will invest £14.2 billion in the project and Laing O’Rourke signed a Programme Alliance Agreement to form the Civil Works Alliance (CWA) with Sizewell C, Balfour Beatty and Bouygues Travaux Publics.
Earlier this month, EDF confirmed that it will take a 12.5% stake in the Sizewell C nuclear plant.
The CWA, who are all already working on the near-replica Hinkley Point C project, will provide a single delivery organisation to Sizewell C responsible for extensive areas of the project including:
- Enabling works and earthworks,
- Marine and tunnelling works,
- Main civils works (Nuclear Island, Conventional Island, Heat Sink and Balance of Plant),
- Ancillary works, permanent roads and networks.
Laing O’Rourke along with Balfour Beatty and Bouygues are delivering the Hinkley Point C project.
This will allow learnings and verified proof-of-concept practices from the construction of Hinkley Point C to be applied by the CWA to the construction of Sizewell C.
Group Chief Executive, Cathal O’Rourke, said:
"Laing O’Rourke is already working with our Alliance partners to plan for this complex project.
We welcome the certainty that this decision brings for the project and are proud to play our part in delivering the next chapter of Britain’s clean energy future.
We’ve learned a lot from the work we’ve done on Hinkley Point C and that experience will power how we deliver this complex project and we are excited to keep working with our partners on this critical project."
