4.1. The NLPG is the de facto addressing solution for all local authorities and increasingly so for its partners. Local Government has invested over £70 million in creating the NLPG and is committed to using it for all its addressing requirements and services.

4.2. The NLPG is the definitive address list that provides unique identification of properties and conforms to the British Standard, BS7666:2006. It covers the whole of England and Wales and contains more than 30 million residential, business, and non-mailing addresses and is now marketed commercially.

4.3. The Council is committed to this initiative through its own Local Land and Property Gazetteer (LLPG) which, together with the other 375 local authorities in England and Wales, makes up the NLPG. Street naming and numbering is the single most important source of address change intelligence for the Council’s LLPG and therefore the NLPG.

4.4. As local authorities are the originators of addressing information, an address dataset, developed and maintained at source by users of the data, will inevitably have the highest level of currency and completeness.
