This page details upcoming data that will be provided for the new Retail Hierarchy Value Code List in the OS NGD from the end of March 2026 to give you early insight. This code list is currently not available through the live access services. The information on this page is as accurate as possible, but is subject to change before launch.

This code list is used in association with the Retail Hierarchy attribute which is present within the Retail Area Aggregated Feature Type. The code list describes the retail hierarchy values that can be assigned to Retail Area Aggregated features.
