Delivering Proven Screening Success at Hinkley Point C and Sizewell C

Rullion has been a trusted candidate background screening provider since 2014, playing a vital role in supporting major UK nuclear infrastructure projects, including Hinkley Point C and Sizewell C. Working across multiple delivery partners and project phases, we’ve helped embed consistent, compliant, and candidate-friendly screening at scale. With over 8,000 candidates screened annually and clearance times reduced to an average of just 7.5 days, our model continues to support project momentum and onboarding efficiency - while maintaining the highest standards of compliance and governance. The Challenge To keep momentum on projects of this scale, pre-employment screening must be robust, accurate, and fast. Every individual working on site requires BPSS (Baseline Personnel Security Standard) clearance before work can begin. With multiple stakeholders, evolving regulatory requirements, and high volumes of candidates, the background screening process can be complex to manage, even with established systems in place. Our clients needed a nuclear screening provider who could bring clarity, consistency, and pace to an already demanding environment. What project teams need: Timely and accurate delivery of BPSS clearance and related vetting checks A positive, well-supported candidate experience Screening support delivered direct to projects like Hinkley Point C and Sizewell C, and across Tier 1 contractors and their supply chains Real-time visibility, control, and governance in screening processes Tier 1 contractors are the principal delivery partners on major projects such as Hinkley Point C and Sizewell C. Supporting them means enabling their workforces and suppliers to clear vetting efficiently, reducing risk of onboarding delays. A Proven Screening Model for Nuclear Environments Our nuclear screening model has evolved over years of delivery, working across early careers, agency-supplied workers, and permanent hires. The service model is grounded in best practice, with compliance and candidate experience at its core. Our solution is built on five key pillars: 1. Speed with Precision We consistently reduce average BPSS clearance times from 30-40 days to fewer than 8 days, using: A dedicated screening portal with automated timelines Electronic document collection via DocuSign One-to-one support from trained candidate advisors “We’re consistently achieving clearances in 7–8 days - and in urgent cases, we’ve turned around checks in just 24 hours,” says Jayne Lee, Head of Screening. 2. BPSS and Beyond We manage all core BPSS clearance elements: Right to work (RTW) Identity and address verification Criminal record checks (DBS) Three to five years referencing We also support CTC and SC clearance preparation where needed, compiling candidate packs ready for formal review. 3. Human-Led Candidate Experience Every candidate is assigned a named advisor who supports them through the screening journey; they answer questions, collect documents, and maintain engagement from start to finish. “We know how to reach the right contact for a reference. Our proactive approach keeps things moving,” adds Jayne. 4. Real-Time Governance Our clients benefit from full transparency throughout: Live dashboards and candidate status tracking SLA-based monitoring and escalation Monthly reporting and governance in screening audits 5. Scalable Across Supply Chains Our solution is used not only by project leads but by Tier 1 contractors across both Hinkley Point C and Sizewell C. The model scales to support different business units and workforce types including; contractors, agency workers, and permanent staff Impact to Date Over 8,000 candidates screened annually 75% reduction in average screening times +69 Net Promoter Score (NPS) from screened candidates BPSS compliance embedded with live audit capability Fully digital, mobile-friendly experience Adopted by Tier 1s across the project supply chain A Benchmark for Nuclear Screening Rullion’s screening model is now a recognised example of best practice in regulated environments, supporting complex infrastructure programmes where delays and drop-offs can have significant impact.
