Why UKAS Accreditation Matters
CCS (Crown Commercial Service) framework eligibility requires UKAS-accredited ISO certificates. UKAS is designated by the UK government under the Accreditation Regulations 2009. Non-UKAS certificates — regardless of how they look — will fail CCS pre-qualification checks. Always verify on iafcertsearch.org and check the CB's UKAS accreditation number on ukas.com.
