Land Data

Land Data Land Data is the official government appointed organisation that manages and regulates the National Land Information Service (NLIS) contracts.

The company was established by IDeA in 2001 to serve the interests of the general public by making authoritative property search information accessible electronically to all, whilst at the same time improving the home buying and selling process. Land Data’s role is to ultimately provide the legal sector, via NLIS, with official electronic land and property information at a fair price, safe in the knowledge that this information is from source and delivered through the only regulated, secure and truly national provider in England and Wales. We do this by working with both public and private partners to improve access to authoritative land and property information. The company’s main activity is the management and regulation of the commercial contracts underpinning NLIS.

The National Land Information Service (NLIS) is the electronic market leader in the conveyancing searches market. Since 2001 it has been providing a secure gateway to authoritative data providers in England and Wales including all 375 Local Authorities (LAs), HMLR, the Coal Authority and water companies.  All searches ordered through an NLIS licensed channel are classified as ‘official’ searches, because users are connected directly to land and property information held by official sources of land and property data. Solicitors and conveyancers benefit from an efficient service, safe in the knowledge that the searches are not only authoritative but comprehensive and insured.  NLIS is the safest, most secure and only regulated data hub in the land and property information market.
