Cyber-attack & data theft: Our response & service status

SPRI Activity & SIC codes

In order to complete a SPRI return, operators must obtain the relevant codes.

Standard Industrial Classification (SIC) codes

Every registered company in the UK has a SIC, which can be found through Companies House website.

The SIC code for a registered company reflects the economic activity of the company. The SIC code reported in SPRI should represent the main economic activity of the site and not the registered company. The current SIC codes are available to download.  

Scottish Pollutant Release Inventory (SPRI) activity codes

The SPRI code reflects the activity or activities permitted to take place on a site as specified in the site authorisation. The SPRI codes allow Scottish sites to be compared to European sites by providing a common system of categorising industrial activities. Most SPRI codes are the same as those listed in the European Pollutant Release and Transfer Register Regulation. Only the Radioactivity codes are different.

The table below provides complete details of the reporting activities and capacity thresholds in SPRI.
