 LevelsNumber of Categories within each level
Letter A - USection21
2 digitDivision88

3 (b)Is the classification structure identical to the international standard or, if not, how does it differ? (e.g. have additional levels been added to the international standard or have changes been made within the level of the international structure, such as aggregations or additional breakdowns)Yes, as described in question 3 (a) above.

Classification uses
4 (a)Please state for which statistical purposes (surveys etc.) this classification is used and if there are users outside of the Statistical Office. Please indicate at which level the classification is used for data collection and for data publishing.Within the Office for National Statistics (ONS), UKSIC (2007) is used within the Interdepartmental Business Register (IDBR), for all business surveys and within the National Accounts.

Data is usually collected either at the 5 digit level (should a 5 digit breakdown exist) or at the 4 digit class level.

Data is published at the 2, 3, 4 and 5 digit levels of UKSIC 2007, dependant on the dictates of factors such as disclosure and user requirement.

A comprehensive range of statistics is published via the ONS website, catering to users that include: Government and non Government bodies, Business and Academia.

4 (b)Please give the names of institutions that use the classification for non-statistical purposes (as opposed to statistical purposes in question 4(a)). Also indicate the kind of use (e.g. tax offices, social security, customs, enterprise register, employment services, work permits etc.)The UKSIC (2007) has been widely implemented across Government and other major institutions for example users include:

Her Majesty Revenue and Customs (HMRC),
Companies House,
Environmental Agency,
Department for Business Innovations and Skills (BIS)
Department of Culture Media and sport.
Department for Transport
The Bank of England

Some of the institutions listed above may include an element of statistical purpose in their usage of UKSIC (2007).

4 (c)Please indicate if alternative classifications are used by other institutions of the economy. Are these classifications available and useful for the Statistical Office?The UKSIC (2007) is used within the Statistical domains in line with the requirements of the NACE Rev.2 legislation.
Implementation / revision status
5 (a)Please state the date of the official adoption of the classification. If not yet adopted, please indicate the current state (e.g. in development, sent for approval, in printing, ready to be distributed etc.)UKSIC (2007) introduced on 1st January 2008
5 (b)Please state the date of use of the classification for individual statistical programmes.Implementation of the UKSIC (2007) in line with the dates specified by Eurostat i.e. with those of NACE Rev.2
5 (c)Are there existing plans for revision or update of the current classification?Not currently
5 (d)Name of former (previous) national classification (full name in both national tongue and in English with acronyms in brackets, should be given)UK Standard Industrial Classification of Economic Activities 2003 (UKSIC (2003))
