Local authority Custodians

Local authorities in Great Britain create local address and local street databases for their administrative areas, which are maintained by the authority through local government’s statutory responsibility to name and number streets. The street data maintained by local authorities via their LSG is underpinned by legislation and used by all organisations with a remit to undertake street and road works, to ensure coordination and appropriate permissions are given for street works.

These are authoritative datasets, complete and regularly updated, so can act as an integrator of disparate datasets and facilitate joined-up decision-making within and between different public sector entities. Every planning authority has as Local Land and Property Gazetteer Custodian (address Custodian) and every highways authority has a Local Street Gazetteer Custodian (street Custodian). Both role are essential for managing and maintaining these essential datasets which are used locally and nationally.
