DSA Checks
DSA Checks are a contractor-delivered inspection and documentation service that supports Defence sites and Defence contractors in demonstrating alignment with Defence Safety Authority safety and environmental governance expectations.
Overview
The service focuses on fuel, gas, and hazardous installations where clear inspection evidence and controlled close-out actions are required to support assurance, audit, or permissioning processes. LCM’s role is to inspect, document, and verify condition and compliance-related matters, not to certify or approve installations.
DSA Checks are typically used to strengthen assurance evidence ahead of Defence reviews, to address gaps identified during audits, or to support continued safe operation of critical infrastructure. The service can be delivered as part of planned assurance activity or in response to identified concerns, defects, or documentation shortfalls.
All activity is scoped to the specific installation, site context, and Defence governance requirements in place. Outputs are designed to be practical, traceable, and suitable for review by Defence stakeholders where required.
Why This Service Matters
Fuel, gas, and hazardous installations on Defence sites are subject to heightened safety and environmental scrutiny. Inadequate inspection records, unclear defect status, or incomplete close-out evidence can increase the risk of audit findings, delayed permissions, or operational restrictions.
DSA Checks help reduce these risks by providing structured inspection evidence and a clear record of findings and actions. Where issues are identified, the service supports proportionate, risk-based close-out rather than broad or unnecessary intervention.
For Duty Holders and Responsible Persons, this supports informed decision-making around continued operation, remedial priorities, and assurance reporting. For Defence contractors, it provides defensible evidence that reasonable inspection and follow-up activity has been undertaken in line with Defence expectations.
The emphasis is on clarity, traceability, and supporting safe operation without overstating compliance outcomes.
Compliance, Standards & Governance
DSA Checks are intended to support Defence safety and environmental governance arrangements. LCM provides inspection activity and evidence that may be used as part of wider Defence assurance, audit, or permission-to-operate processes.
LCM does not act as a regulator and does not issue licences, approvals, or certifications. Any references to compliance are framed in terms of supporting alignment with relevant Defence regulations, guidance, and local governance requirements, where applicable.
All findings and outputs are provided to enable Defence stakeholders to make their own determinations based on the available evidence.
Typical Use Environments
DSA Checks are typically undertaken within:
• UK Defence estate installations
• Defence-controlled or Defence-governed activities where Defence Safety Authority rules apply
• Fuel and gas storage or dispensing infrastructure supporting Defence operations
The exact scope is confirmed during the initial review to reflect site-specific conditions and access constraints.
Planned vs Reactive Use
Planned use
DSA Checks are most commonly used as a planned assurance activity, forming part of routine inspection programmes or pre-audit preparation.
Reactive use
They may also be used reactively where concerns have been raised, documentation is incomplete, or defects have been identified that require structured inspection and close-out.
What happens next?
The next step is an initial technical discussion to confirm the installation type, site constraints, inspection history, and intended outcomes. From this, the inspection scope, programme, and evidence requirements are agreed before site attendance. This ensures the service is proportionate, relevant, and aligned with Defence governance expectations from the outset.
