The UK nuclear workforce rose by 7.2% in the year to the end of October 2025, taking the number of workers in the sector to 102,867 as both defence and civil nuclear projects ramped up, according to data in a new report.

The Nuclear Workforce Assessment 2025 report said that of that total, 55,133 people worked in civil nuclear, while 47,734 were in the defence sector. Of the total, 81,662 were direct workers while the rest worked in supply chain companies.

It cautioned that work remains to be done to make sure hiring increases among younger workers and skills are transferred to the next generation.
