UKAS, ISO/IEC 17021-1:2022 and the conformity assessment transition

What changed in 17021-1:2022

ISO/IEC 17021-1:2022 sharpens the requirements on certification bodies that audit management systems. The clauses on impartiality, competence and audit-time calculations have all been tightened, and UKAS-accredited bodies must evidence conformity as their assessments cycle through.

Impact on audit programmes

Certification bodies are re-examining audit-time tables, sampling of multi-site organisations and how they evidence competence for auditors working across sectors. For clients this typically shows up as clearer scoping conversations at contract renewal and more explicit competence records shared during audits.

Impact on clients

  • Expect more specific competence records for lead auditors and technical experts.
  • Expect clearer impartiality declarations, including consultancy relationships in the last two years.
  • Expect audit programmes that are risk-based, not templated by sector.
  • Expect Stage 1 reports that actually shape Stage 2 sampling.

Community discussion

Different UKAS-accredited certification bodies are interpreting the transition slightly differently. The UKAS hub is where practitioners are sharing what they are seeing in practice — from time calculations to how impartiality committees are being run.
