Your LLPG is probably the most valuable dataset that you own.

Initiatives such as Tell Us Once and Government Gateway mean that public sector organizations must concentrate on integrating their systems and data to improve data quality and the provision of service. By reducing the number of address sources within each authority to the single, definitive LLPG, an authority can save time and resources and improve data sharing.

Every authority needs to maximise their investment in the work already done to create their LLPG. You are already paying for the data, so it makes sense to use it to gain operational efficiencies and increased confidence in address data.

NLPG Anywhere can help LLPG custodians to meet the Ten-day rule which states that they must notify errors or amendments to the LLPG "Hub" within 10 days.

When an address is included in the NLPG it is given a Unique Property Reference Number (UPRN), which stays with the property forever, even if it is subsequently demolished. This means that name changes, postcode re-coding, changes of use etc. do not affect the UPRN, so any historic information about a property stays with it in perpetuity.

The Unique Property Reference Number (UPRN) is used to join together the records systems of all departments within an organization as they often different version of the same address, leading to duplicate letters being issued, increased cost and poor customer service. The UPRN means that it is possible to link information about a specific address across multiple instances where that address is held e.g.

Data held by Revenues
UPRN: 1234567
Basement Flat
Rear of 10, St. Catherine St
Data held by Electoral Services
UPRN: 1234567
"Myholme"
10, Saint Cathryn Street
Data held by Customer services
UPRN: 1234567
Flat 10,
St Catharine’s St
Data held by waste collection
UDPRN: 1234567
My Home
10 St. Catherine Street

By capturing the UPRN it is possible to store information in a single, standard format.

LLPG data is constantly updated and is quality-checked against other data sources. It includes information such as details about proposed developments, classifications such as whether land is commercial, residential or military and contains geographical references so that it can be linked to aerial photography, topographic and digital mapping.
