## Summary

The Security Industry Authority (SIA), based in London, England, has completed a procurement process through a concession contract titled "Approved Contractor Scheme." This process, classified under the industry category of Corporate Governance Rating Services (CPV code 79212110), involves awarding the delivery of assessment services related to security services providers. The process followed an open procedure, targeting UKAS accredited certification bodies and has a contract term from 7th October 2025 to 7th October 2029, spanning up to four years with options for extension. The contract awards were published on 31st October 2025, following a tendering period that ended on 9th January 2025. The procurement was managed electronically, requiring bidders to register on the Home Office's eSourcing Portal. The total estimated value of the procurement was £12,500,000 GBP.

This tender presents substantial opportunities for businesses in the security and certification industries, especially those classified as small and medium enterprises (SMEs), which were explicitly invited to participate. The winning suppliers, such as British Assessment Bureau Limited and Insight Certification Ltd T/A NSI, will have the chance to compete for clients within the SIA's Approved Contractor Scheme without direct financial transactions with the SIA, allowing them to foster competitive commercial relationships. Such a concession framework can enhance the reputation and market reach of the awarded certification bodies, particularly benefiting businesses focused on corporate governance and security services ratings across the United Kingdom. Businesses looking to expand into the security assessment sector would find this scheme advantageous for growth and credibility enhancement.
