Who We Are
WalHan Group (WHG) is a specialist compliance and assurance consultancy with deep roots in the UK defence sector. We exist to help organisations navigate the complex, overlapping framework of standards, regulations, and publications that govern defence — from ISO certifications and Defence Standards to JSP frameworks and NATO quality requirements.
Our work spans the full compliance lifecycle: gap analysis, system design, implementation, internal audit, certification support, and ongoing maintenance. We work with defence primes, SMEs entering the supply chain, and public sector organisations that need to demonstrate assurance to the MOD and its stakeholders.
We are not a generalist consultancy that occasionally works in defence. Defence compliance is what we do — exclusively, and with the rigour that the sector demands.
Our Commitment
ASSURE | IMPROVE | ENABLE | TOGETHER
Global Compliance & Assurance — serving the UK defence sector and its supply chain.
Our Specialisms
WHG provides expert support across every dimension of defence compliance — from the standards that govern quality and safety to the frameworks that underpin security and operational resilience.
Defence Standards
Def Stan series, JSPs, AQAPs, and STANAG — we build management systems that satisfy MOD requirements and withstand rigorous audit scrutiny.
ISO Quality Management
ISO 9001 and AS9100 implementation with a defence-sector focus — aligned to Def Stan 05-061 and AQAP 2110/2120 requirements.
Information Security
ISO 27001 ISMS design and implementation aligned with JSP 440 and Def Stan 05-135 — protecting classified and sensitive defence information.
Health, Safety & Environment
ISO 45001 and ISO 14001 implementation aligned with JSP 375 — embedding safety and environmental responsibility across defence operations.
Supply Chain Assurance
Independent supplier audits, qualification programmes, and SCMG-aligned supply chain management for defence primes and tier-one suppliers.
Business Continuity
ISO 22301 business continuity management — ensuring your organisation can sustain and recover critical defence functions under any conditions.

Why Organisations Choose WHG
The defence compliance landscape is not static. Standards evolve, JSPs are updated, and the MOD's expectations of its supply chain continue to rise. Organisations that treat compliance as a one-time exercise — rather than an embedded capability — find themselves repeatedly exposed.
WHG builds compliance systems that are designed to last. We focus on embedding genuine understanding of the standards within your organisation, not just producing documentation that satisfies an audit. Our goal is to leave your team more capable than we found it.
Our consultants bring direct experience of working within and alongside the MOD, defence primes, and the wider supply chain. We understand what auditors look for, what the standards actually require, and how to build systems that satisfy both.
Work With WHG
Whether you are preparing for a first MOD contract, pursuing ISO certification, or strengthening an existing compliance programme — we would welcome the opportunity to discuss how WHG can support your organisation.
