Nuclear jobs in Leiston, what candidates and hiring managers need to know

Leiston in Suffolk has become a focal point for UK nuclear activity, with the heritage of Sizewell A, the ongoing operation of Sizewell B, and the ramp up of Sizewell C.

Significant public and private investment, a fast-maturing supply chain, and new training capacity are combining to create long term opportunities for skilled people and ambitious hiring managers.

This guide brings together facts and timelines from regional and industry sources, and explains how Astute supports candidates and employers who want to engage with nuclear jobs Leiston in a practical way.

Why Leiston is central to UK nuclear activity

Leiston’s connection to nuclear power is anchored by three stations, Sizewell A, Sizewell B, and Sizewell C.

Sizewell A, a twin Magnox station, generated from 1966 until 2006.

Defuelling completed in 2014, with full site clearance expected by 2077, which confirms a long decommissioning horizon for specialist teams in the area, according to World Nuclear News, June 2025.

Sizewell B, the UK’s only Pressurised Water Reactor, entered service in 1995 and employs around 500 staff during standard operations, with larger temporary contractor numbers during outages.

A planned life extension to 2055 is in train, subject to regulatory approval, and has been presented as a way to retain jobs and sustain the local skills base, as noted by The Guardian, September 2025.

Sizewell C is the major growth driver.

Development consent was secured in July 2022, a Nuclear Site Licence was granted in 2024, and the Government confirmed the Final Investment Decision in July 2025.

The project is described as a twin EPR build with an estimated cost of about £38 billion, a construction window of 9 to 12 years, and an expected 3.2 GW capacity that can power about six million homes, with an intended operating life of at least 60 years, noted by Sizewell C, June 2025 and East Suffolk Council, July 2025.

British ownership has increased, and large packages are now flowing to suppliers.

This programme underpins a wide mix of permanent and contract opportunities through construction, commissioning, and eventual operations, with the local economy set to benefit in a measurable way.

Workforce and supply chain strategies have been advanced by local authorities and industry to align with this growth.

Suffolk County Council set out an Asset Skills Enhancement and Capability fund worth £7.8 million to expand training capacity and match the project’s phased needs, described by Suffolk County Council, July 2025.

Suffolk New College announced plans for a post-16 Energy Skills College in Leiston, branded College on the Coast, alongside an apprenticeship and trainee hub that will support up to 540 apprentices.

These plans speak to the scale of the opportunity and the need for structured pipelines into nuclear, reported by Suffolk New College, 2023.

Together, these milestones and investments explain why nuclear recruitment Leiston is now a strategic priority for many employers and candidates.

The roles Astute recruits in nuclear

Astute works across the full value chain of nuclear recruitment.

We support clients who need complete teams for project delivery and operations.

Hiring managers engage us to fill engineering, projects, operations, maintenance, HSE, quality, commercial, and support functions.

Our approach balances speed, compliance, and technical depth, and we build talent pools that reflect the sequencing of a large programme in construction and commissioning, then steady state operations.

Candidates who want to explore live and upcoming requirements can review Astute Nuclear recruitment to understand the scope of our work.

Engineering covers EC&I, electrical, mechanical, civil and structural, nuclear systems, and process.

Project delivery spans project managers, package managers, planners and schedulers, cost and commercial specialists, document controllers, and commissioning managers.

Operations includes control room operators, shift team leads, and field operations staff, particularly in the run up to commissioning for new build or as part of the Sizewell B life extension.

Maintenance includes technicians and engineers for mechanical, electrical, and instrumentation, with outage planning and reliability engineering in scope.

Safety and quality roles include HSE managers, Radiation Protection Advisors and Supervisors, quality engineers, welding inspectors, and NDT specialists.

Commercial and support functions cover procurement, QS, contract management, HR, training, IT support, and administration.

The breadth of roles reflects the complexity of nuclear delivery and the importance of SQEP across the workforce, which is consistently emphasised by station licence conditions.

Engineering and maintenance roles in demand

EC&I engineers, electrical engineers, and mechanical engineers are central to delivery in Leiston.

Employers request practical experience with PLC and SCADA, calibration, alarm management, and functional safety within a nuclear context.

Electrical competence remains vital, with knowledge of 18th Edition wiring regulations, high voltage and low voltage systems, authorisations as an Authorised Person or Senior Authorised Person for switching, and hands-on diagnostics across protection and control equipment.

Mechanical skills linked to pressure systems, rotating machinery, cooling water equipment, valves, and welding are consistently requested, and the ability to read P&IDs and follow rigorous work packs is essential on a licensed site.

Computerised Maintenance Management Systems experience is widely valued.

CMMS proficiency supports backlog control, defect elimination, and outage planning. At Sizewell B, planned outages draw in hundreds of additional contractors to complete intensive scopes, which illustrates the scale of mobilisation required in a relatively tight window, as reported by NucNet, May 2024.

With Sizewell C now moving through early works toward major civils and then mechanical and electrical installation, demand will intensify for technicians, supervisors, authorising engineers, and maintenance coordinators who can work within permit-to-work systems and comply with nuclear safety culture expectations.

Project delivery, planning, and controls

Project professionals anchor the programme.

Planners and schedulers who are fluent in Primavera P6, change control, and critical path analysis are sought for workface planning and integration.

Cost engineers and project controls analysts with Earned Value Management experience help drive visibility and predictability. Package managers are asked to manage interfaces with civils, M&E, and QA teams, and to maintain robust contract and commercial discipline under NEC forms.

Document controllers maintain controlled records, which is a core requirement for assurance and handover.

Certifications such as APMP or PMP are requested in many adverts, and familiarity with NEC3 or NEC4 is considered a practical advantage across Sizewell work packages, as noted by sector guidance in Airswift, 2025.

Commissioning managers need to knit together test regimes, turnover, and punch list clearance in line with licence conditions and environmental permits, which references the wider regulatory environment that shapes every decision.

Safety, quality, and regulatory

Safety, quality, and regulation define nuclear delivery.

HSE leaders with NEBOSH and deep awareness of CDM regulations, IRR17, and environmental permitting are required on sites where conventional construction risks meet nuclear-specific radiological controls.

Radiation Protection Advisors and Radiation Protection Supervisors are essential for dose management and ALARP, with training programmes in place across the region to support competence development.

Quality teams implement ISO 9001 systems and nuclear-specific standards, with ISO 19443 for suppliers increasingly relevant.

Welding inspectors with CSWIP, and NDT technicians with PCN Level 2 or Level 3 in ultrasonic or radiographic techniques, carry out inspections that support right-first-time construction.

The planned Centre of Excellence connected to Sizewell C aims to embed quality and safety behaviours from first principles, noted by Suffolk New College, 2023.

Employers seek professionals who can lead audits, manage non-conformance to resolution, and evidence a track record of safe, compliant delivery under the scrutiny of the Office for Nuclear Regulation and the Environment Agency.

Transfer your skills into nuclear

Nuclear benefits from a wide pool of adjacent industry skills.

Engineers and technicians from conventional power generation, oil and gas, defence, and pharmaceutical manufacturing often possess the procedural discipline, permit literacy, and safety mindset required on a licensed site.

Nuclear Engineering International reported that a large majority of oil and gas professionals are open to moving into sectors like nuclear, and that multi-skilled maintenance and project capabilities translate well with targeted upskilling, cited by NEI Magazine, 2023.

Conversion courses and short programmes in nuclear safety culture, introduction to nuclear power, and supervisor training are already available through regional providers.

East Coast College’s Nucleus employability hub and short courses support residents who want to step into nuclear careers, described by Sizewell C, 2024.

West Suffolk College’s Energy Ready programme helps local businesses and workers align skills to energy projects, noted by Sizewell C Supply Chain, 2025.

These routes give candidates a practical bridge into EC&I jobs Suffolk, nuclear maintenance roles, and project controls nuclear positions around Leiston.
