Nuclear and energy demand a different standard of control.

Nuclear and energy combines regulatory oversight with the power to halt operations, security clearance requirements imposed by law, parliamentary accountability for programme failure, and operational continuity constraints that simply don't exist in commercial environments. The combination creates a governance requirement that is categorically more demanding than any other regulated sector.

Most regulated industries — pharmaceuticals, financial services, utilities — have compliance requirements that add complexity to SAP programmes. Nuclear and energy goes further. Every technology change intersects with ONR requirements, export control legislation, and nuclear safeguards law. Programme failures attract parliamentary scrutiny and Public Accounts Committee review. Security clearances restrict who can work on the programme by nationality and clearance level. And operational continuity is non-negotiable — the programme must work around the facility, not the other way around. The governance model required in this environment is fundamentally different from any other sector.

Security clearance requirements vary by organisation and programme. Limelight treats clearance requirements — including nationality restrictions that apply to certain nuclear safeguards programmes — as a programme design constraint from the outset, not an afterthought.

The clearance profile required varies significantly by organisation, programme type, and the specific nuclear safeguards obligations in play. Limelight works with organisations at the outset of each engagement to understand exactly what is required and ensures our team is appropriately resourced and cleared for the work. Where nationality restrictions apply — as they do in certain nuclear fuel cycle programmes — we address this as a resourcing constraint to be planned around, not discovered mid-programme.

In nuclear and energy, the conflict of interest created by SI-led governance is not merely commercial — it is regulatory. An SI assessing its own readiness to meet a nuclear compliance deadline creates exposure no CIO can accept. Limelight provides the independent client-side governance layer that resolves this structurally.

Every SI involved in nuclear and energy SAP delivery has a commercial model that benefits when programmes run longer. In most sectors this creates a commercial tension. In nuclear and energy it creates a regulatory one — because the party with the financial incentive to extend the programme is also the party being asked to assess its own readiness, sign off its own cutover plan, and report its own progress to the board. Limelight resolves this by sitting on the client side exclusively — owning the assurance function, the SI management relationship, and the readiness assessment without the commercial conflict that makes SI self-governance unacceptable in this environment.

Yes. Limelight has delivered SAP programmes across multiple countries and time zones. Our senior directors have experience in multi-site, multi-country regulated environments and we are structured to support international programmes.

Limelight has delivered complex, multi-site, multi-country SAP programmes across Europe and beyond. Our senior directors have direct experience operating in international regulated environments — managing distributed teams, navigating multi-jurisdiction compliance requirements, and delivering programmes that span multiple time zones simultaneously. We would always discuss the specific requirements of an international engagement at the outset — including any nationality or security clearance constraints that apply — to ensure we are appropriately resourced for the work.

A structured conversation with a Limelight senior director — no commitment required. For organisations that prefer a structured starting point, a RunHealthy Assessment provides an independent view of your current programme's readiness in four to six weeks.

Every Limelight engagement starts with a sixty to ninety minute conversation with a senior director. We will listen to where you are, ask the questions that matter, and give you an honest view of what we think — including whether and how Limelight is the right fit for your specific situation. For nuclear and energy organisations already in a programme that needs independent assurance, a RunHealthy Assessment is often the right entry point — a structured, evidence-based audit completed in four to six weeks with no ongoing commitment required. For organisations at the start of their journey, RunFast Launchpad is the conversation to have.
