There is a new version of the NCSD which is supplied to BODS via its contract with KPMG. The old version is supplied by contract with Basemap. Both contracts and NCSD versions currently run in parallel, with the objective to move all consumers onto the new version from a date tbc by the DfT BODS team.
There are some differences between the old and the new version of the NCSD which data consumers are discussing with KPMG.
