It is important that the market has assurance that the conformity assessment bodies (CABs) themselves operate to acceptable standards and this is the purpose of accreditation. The accreditation process determines, in the public interest, the technical competence and integrity of organisations such as those offering testing, calibration and certification services (commonly referred to as conformity assessment).

UKAC accreditation sends a clear message. It says your certification or inspection body can be counted on to perform its duties—in an authoritative and impartial way. It flags that you have been approved by an independent third-party as a professional body that acts with integrity when certifying or inspecting for conformity assessment.

Third-party accreditation is recognized around the world as the highest and most credible type a certification or inspection body can obtain.


Accreditation, which operates across all market sectors, provides an impartial assessment against internationally recognized standards. UKAC accreditation is internationally recognised. This symbol of assurance offers you many direct benefits.

  • Highlights your competence and credibility.
  • Confirms you are independent and impartial.
  • UKAC provides you international recognition with the international accreditation organisations through the IAB agreement know as (WAA).
  • Enables you to benchmark ongoing performance against relevant standards.
  • Informs your clients you have meet the highest level of assessment and professionalism in the industry.
  • Flags your ability to meet mandatory regularly requirements.
  • Strengthens your ability to compete overall.
Accredited organisations

Accreditation is objective proof that conformity assessment organisations conform with recognized standards. It is the internationally recognized system that is used to develop and sustain high standards of performance.


Accredited conformity assessment gives consumers confidence through ensuring consistently high standards in the quality of products or services purchased. Accreditation throughout the market chain is increasingly important. The business world we live in is growing quickly and is highly complex with many inspectors and certifiers operating without accreditation. This is risky for all players, right through to the ultimate consumer.

Without accreditation there is no certainty that goods and services can be depended upon. On the other hand, accreditation provides certainty in a world where standardisation and certification are an integral part of the global economy. And it supports trade and commerce.

UKAC offers accreditation for these themes to support government, industry and the community to achieve their goals:

  1. business process and innovation
  2. health and human services
  3. product certification
  4. food and biological systems
  5. environment

UKAC accreditation process is systematic and comprehensive in its assessment of an applicant’s capabilities and systems.

Before our Governing Board grants an accreditation, the conditions of accreditation—as set out in our detailed accreditation manual—must be met.

Our accreditation process is open, transparent, fair and ethical—every step of the way. Once accreditation is granted, you sign an accreditation deed and agree to all of its undertakings. We then monitor compliance and request adjustments or withdraw your accreditation should you not be fully complying.

After four years, bodies need to apply to be re-accredited.
