Why we watch it
The UK's first new nuclear build in a generation — years more of heavy electromechanical, instrumentation and commissioning work ahead, and a well-documented case study in how schedule risk and productivity shortfalls play out on a first-of-a-kind reactor build.
Phase in full, as reported
construction (electromechanical installation phase, per EDF's 2026 schedule update)
Reported risk in full, as reported
Delayed a year to 2030; total project cost risen to about £35bn (nearly double the original 2016 estimate, ~£48.7bn in today's terms), with EDF citing lower-than-expected productivity in its electromechanical installation programme; a further delay to 2031 could add ~£1bn more.
Who builds it as stated by the sources
Operator / developerEDF (with China General Nuclear as minority partner)
- EDFdeveloper, majority owner, main contractor
- China General Nuclear (CGN)minority investment partner
Key dates as stated by the sources
- Unit1 target
- 2030 (revised, one year later than previous target)
Disciplines likely needed our inference
- E&I supervision
- mechanical/piping construction
- QA/QC
- construction management
- commissioning (later phase)
