The United Kingdom Accreditation Service (UKAS) is the sole National Accreditation Body for the United Kingdom. UKAS is recognised by Government, to assess against nationally and internationally agreed standards, organisations that provide conformity assessment services such as certification, testing, inspection, calibration and verification.

Accreditation by UKAS demonstrates the competence, impartiality and performance capability of these evaluators. In short, UKAS ‘checks the checkers’.

No Data Found


Until we receive an application for accreditation which details the size of your operation, it is very difficult to provide you with an accurate estimate as to what it will cost you to become UKAS-accredited.

All assessment fees are effort related; i.e. – dependent on the complexity of scope of accreditation being sought. These fees include not just the time the assessment team spend at your site but also office time. A list of current fees can be found in the UKAS Standard Terms of Business.

NAS's Review

UKAS is independent of Government but operates under a Memorandum of Understanding with Government through the Secretary of State for Business, Energy and Industrial Strategy (BEIS). UKAS is licensed by BEIS to use and confer the national accreditation symbols which symbolise Government recognition of the accreditation process.

UKAS is a non-profit-distributing private company, limited by guarantee. It operates as an independent body providing a public authority activity and operating in the public interest. UKAS is self-financing and charges fees to conformity assessment bodies to cover operational costs and other expenditure.
