How Sizewell C is Driving Demand for Talent in the UK
On this page
Sizewell C: Project Overview
Sizewell C jobs are set to become one of the biggest drivers of nuclear hiring the UK has seen in a generation. The UK is on the cusp of a major energy transformation, placing nuclear power firmly at the heart of its future strategy. This renewed commitment to clean, secure, homegrown energy is encapsulated in one of the nation’s most ambitious infrastructure projects: Sizewell C.
The UK government’s announcement of a £14.2 billion investment into the construction of this nuclear power plant in Suffolk is a landmark moment, and a major driver of Sizewell C jobs across the supply chain (GOV.UK, 2025).
The project, designed to power approximately six million homes for over 60 years, marks the most ambitious nuclear building programme in a generation — see our full guide to Sizewell C for the wider project background.
For businesses involved in this colossal undertaking, the ability to source and place highly vetted UK nuclear talent quickly will be the single most critical factor for success. Astute People, with our dedicated nuclear recruitment UK expertise, is ready to meet this challenge.
The project is forecast to create 10,000 jobs at peak construction, including 1,500 apprenticeships, supporting thousands more across the nationwide supply chain, with an estimated 70% of construction value going to British businesses (GOV.UK, 2025).
The Nuclear Talent Gap: Challenges on the Horizon
The surge in Sizewell C jobs comes amid a challenging backdrop within the UK’s nuclear industry. The sector’s workforce has reached a record 98,173 people, up 11,000 in a year and 55% over the past decade (NIA Jobs Map, 2025), yet still faces a severe talent shortfall.
With projects like Hinkley Point C, Sizewell C, and the AUKUS submarine programme, the sector is forecast to require 40,000 additional skilled workers by 2030 (National Nuclear Strategic Plan for Skills, Nuclear Skills Delivery Group, 2024).
The Ageing Workforce Crisis: Around 39% of the Engineering Construction Industry (ECI) workforce in nuclear is over 50 (ECITB, 2021), creating a knowledge gap as experienced workers retire faster than new talent enters the sector.
Intense Competition in a High-Demand Sector: Nuclear competes with renewables, defence, and infrastructure for engineering, project management, and technical roles. Over 90% of ECI employers in nuclear report recruitment challenges, particularly for mechanical/electrical engineers and project controls specialists.
Highly Regulated Environment and Security Clearance: Roles require vetting through BPSS, Security Check (SC), or Developed Vetting (DV) (UK Parliament, 2024), adding months of recruitment delay.
The Need for ‘Nuclearisation’ of Skills: Transferable skills from aerospace, defence, or oil & gas must be ‘nuclearised’ — specialised training in safety culture, regulations, and technology — to meet nuclear construction careers demands.
Sizewell C Jobs: 10 High-Demand Nuclear Roles
Sizewell C will generate demand across all project stages. Businesses can register nuclear job vacancies to access skilled candidates quickly. For the broader picture of which nuclear roles are hardest to fill UK-wide, see our guide to the 10 most in-demand roles in nuclear.
