Using the UPRN to service customers better in Salford

Salford Council want to provide and promote a quicker, easier, better online way to council services and in light of this, have introduced an ‘Intelligent Information Provision’ concept. This concept is designed to use data they have in existing systems to allow them to gain insight into customer needs and where possible encourage them to go online.
