Diamond Engineering has achieved JOSCAR accreditation, marking a significant milestone in the company’s continued development and strengthening its position within the UK defence supply chain.

JOSCAR, the Joint Supply Chain Accreditation Register, is a collaborative accreditation system used by organisations across the defence industry to assess and verify information about their suppliers. Achieving accreditation demonstrates that Diamond Engineering has successfully completed a rigorous pre-qualification process and provides greater assurance to customers that the business meets the required standards for working within the defence supply chain.

For Diamond Engineering, this represents an important step in its growing focus on the defence sector. The company has continued to develop its capabilities, facilities and quality systems to meet the requirements of customers operating in industries where reliability, technical capability, quality and supply chain assurance are essential.

Based in South Yorkshire, Diamond Engineering provides a comprehensive range of manufacturing services, including complex fabrication and welding, CNC machining, material processing, assembly and testing. The company has the capability to manufacture large and complex steelwork and components, supporting customers across a range of demanding applications.

The achievement of JOSCAR accreditation further strengthens Diamond Engineering’s credentials when engaging with defence organisations and major contractors. It also supports the company’s ambitions to develop new relationships and opportunities within the UK defence sector, while demonstrating its commitment to maintaining the standards expected of a trusted supply chain partner.

JOSCAR accreditation follows a period of continued investment and development across Diamond Engineering, including significant investment in manufacturing equipment, facilities and workforce capability. These investments are helping the business increase capacity and take on increasingly complex work.

The accreditation is therefore an important part of a wider journey for Diamond Engineering as it continues to build its presence within the defence supply chain.

With JOSCAR accreditation now in place, the company is well positioned to continue developing its defence offering and pursuing opportunities to support organisations and programmes across the UK.

For Diamond Engineering, this is an important achievement and another step towards establishing the business as a trusted, capable and dependable manufacturing partner within the defence sector.
