BSI is recognized as the UK National Standards Body (NSB) by the UK Government. This status is formally codified in the Memorandum of Understanding (MoU) between the United Kingdom Government and the British Standards Institution in respect of its activities as the United Kingdom’s National Standards Body.
The MoU recognizes BSI’s status as the UK member of the international standards organizations, ISO and IEC; the European standards organizations, CEN and CENELEC; and as the National Standards Organization (NSO) participating on behalf of the UK in ETSI.
The MoU defines a number of key responsibilities for BSI as the NSB. Its membership of the international and European standards bodies also entails a number of specific responsibilities. In addition, there are certain aspects of BSI’s work that are further defined through the , to which the UK Government is a signatory.
Most of BSI’s responsibilities are undertaken on a day-to-day basis by BSI Standards Ltd, a wholly owned subsidiary company of BSI Group. A Supply of Services Agreement sets the framework by which this can be systematically monitored.
