Globally, Leonardo operates in the aerospace, defence and security industries, annually procuring a wide range of products and services. Across the UK, Leonardo works with more than 2,100 suppliers, two thirds of whom are SMEs.

Maintaining healthy and productive relationships with all our suppliers is critical to our continued success, and we are always looking for additional suppliers and partners who share our principles of integrity, transparency and trust. This all contributes to ensuring the company's operational excellence.

Leonardo is a signatory of the UK Aerospace Growth Partnership Supply Chain Competitiveness Charter, and as such, supports structured supply chain continuous improvement programmes SC21 Operational Excellence (OE) and Competitiveness and Growth (C+G). It is expected of our incumbent and future UK suppliers to be engaged on these programmes in order to sustainably develop their businesses, to further be competitive in the international marketplace, and to invest in technology to radically improve product performance and manufacturing productivity.

For the supply of aircraft components, we require all suppliers to have AS9100 series Accreditation, NADCAP Accreditation (for the supply of manufactured articles which involve special processes) and Catia V5 for transfer to digital models.


Leonardo’s UK Electronics business maintains a global supply base in support of operations across the UK. We place great emphasis on risk management and ensuring full transparency in our supply chain. All suppliers are expected to adhere to Leonardo’s Supplier Code of Conduct, Code of Ethics and Modern Slavery Statement.

Our values and requirements of our suppliers are expressed in our General Conditions of Purchase.

Around three quarters of our UK Electronics business suppliers are Small and Medium-sized Enterprises (SMEs) and we welcome further opportunities to engage with the SME community. The business actively supports the UK MoD SME Action Plan.

Leonardo’s UK Electronics business is also a founding member of the Joint Supplier Accreditation Register (JOSCAR) initiative, which is an industry-wide source of supplier qualification and compliance information. Leonardo encourages all suppliers to participate in JOSCAR. The benefits to Leonardo of participation in JOSCAR as a Buyer are:

  • An in-depth approach to supplier qualification which supplements our existing in-house practices and enables us to declare compliance against Leonardo corporate standards.
  • An easily accessible library of supplier information as a reference point for our existing performance management practices and business reviews.
  • A means by which to promote supplier compliance against emerging industry standards and regulations.
  • A source of information to fulfil our internal and customer-driven supply chain risk management initiatives, such as Business Continuity Management.
  • A benchmark for our Category Strategies and a reference point discriminator for our source selection activities.
