Both the NLPG and NSG created a new standard of currency and completeness for location data.
Following negotiations last year with Ordnance Survey, who have historically used the Royal Mail Postcode Address File (PAF) to create geocoded address database products, agreement was reached for the Local Government Group and Ordnance Survey to form a joint venture - called GeoPlace LLP - and to acquire Intelligent Addressing Limited and merge their respective addressing operations to create a definitive national address database for England and Wales.
These plans were announced by Eric Pickles MP, Secretary of State for Communities and Local Government in December 2010.
The agreement was subject to approval from the Office of Fair Trading (OFT). Today, 15th February 2011, the OFT gave clearance to the merger (http://www.oft.gov.uk/news-and-updates/press/2011/18-11) and thus the completion of the transaction is anticipated to take place over the next 8 weeks.
