ISO Certification in Europe: Accredited Audits Across the EU, EEA, and Switzerland
ISO certification in Europe helps suppliers meet buyer requirements that are tightening under GDPR, NIS2, and the EU AI Act. Accredify Global audits organizations across 26 European countries from one coordinated program, so a group with sites in several countries can certify under one scope.
How ISO Certification Works for European Companies
ISO certification in Europe follows the same international rules as anywhere else: an accredited certification body audits your management system and issues a three-year certificate with yearly surveillance. What differs is the pressure behind it. EU law now pushes security, privacy, and sustainability duties down supply chains, and certificates are one of the main ways suppliers prove they keep up.
Many European groups run sites in several countries. A multi-site certificate can cover all of them under one management system, with audits sampling different locations each year.
Accredify Global is accredited by UAF. Some European tenders name a national accreditation body, such as DAkkS, COFRAC, or ACCREDIA, or ask for any member of the European co-operation for Accreditation. Check the clause before you book.

FAQ: ISO Certification in Europe
Can one certificate cover sites in several European countries?
Yes, if they run one management system under the same organization. A multi-site certificate lists every site, and audits sample sites across countries each year.
Do European tenders require a national accreditation body?
Some do, naming DAkkS, COFRAC, ACCREDIA or another national body. Many accept any accreditation body in the international arrangement. Send us the clause first.
Is Accredify Global accredited?
Yes. Accredify Global is accredited by UAF for twelve standards, including ISO 9001, ISO 14001, ISO 45001 and ISO 27001.
Does ISO 27001 cover NIS2?
It covers much of it. NIS2 asks for risk management, incident handling and supply-chain security, which ISO 27001 manages. Reporting duties to national authorities must still be met separately.
Can audits be done in local languages?
Tell us your preferred language at scoping. Key records in English make audits faster and can reduce audit days.
How long does certification take in Europe?
Most organizations with a working system certify 6 to 12 weeks after Stage 1. Multi-country groups need longer to schedule site audits.
