What is accreditation?

Accreditation determines the technical competence and integrity of organisations offering conformity assessment services such as testing, certification, inspection and calibration. Find out more about accreditation.

This short video shows the impact that accreditation has on our everyday lives.

How can accreditation help small businesses?

If your business requires the services of certification bodies, testing or calibration laboratories, or inspection bodies, using a UKAS-accredited supplier for these evaluation services (also known as conformity assessment services) is an essential tool for decision-making and risk management.

Organisations can save time and money by selecting an accredited and therefore competent supplier. Accredited testing, inspection and certification carried out in compliance with best practices can limit product failure and down time, and control manufacturing costs.

Using accredited services can:

  • de-risk your procurement by taking the guesswork out of choosing an evaluation body
  • open up new business opportunities as accreditation is specified by procurement officials
  • demonstrate due diligence in the event of legal action
  • help with knowledge transfer and product development since accredited evaluation bodies can be a good source of impartial advice

A Guide for Small Businesses seeking evaluation services is available .
