UK SIC 2007 71121: Engineering design activities for industrial process and production

Maps to NACE Rev. 2 71.12 and NACE Rev. 2.1 71.12. ISIC Rev. 4: 7110.

UK SIC 2007 code 71121 is "Engineering design activities for industrial process and production". UK SIC 2007 follows NACE Rev. 2 at four digits and adds a national fifth digit, so the first four digits, 71.12, are the NACE Rev. 2 class "Engineering activities and related technical consultancy". UK companies state one or more SIC codes when they file at Companies House, and the codes appear in the company record. In NACE Rev. 2.1 the matching class is 71.12, "Engineering activities and related technical consultancy".
