The United Kingdom Accreditation Service (UKAS) is the sole national accreditation body recognised by government to assess, against internationally agreed standards, organisations that provide certification, testing, inspection and calibration services.

Cirrus Environmental Solutions Ltd holds UKAS Accreditation for a range of emission monitoring tests.



The Benefits to You, the Client

Using a UKAS-accredited supplier such as Cirrus Environmental Solutions Ltd ensures that you are making a confident and informed choice about the quality and reliability of the service you will receive.

Accreditation by UKAS demonstrates our technical competence, integrity, impartiality, and performance in the field of emission monitoring.


Who requires UKAS Accreditation?

  • Companies whose business operate in an environment where tests are safety-critical
  • In environments where the accuracy of test results have legal repercussions
  • Companies who are looking to ‘de-risk’ their supply chain
  • Companies which understand that technical competence of their supplier is essential to their business.

It is highly likely that your organisation fits into one or more of these categories. If so, we can help you.
