Land Securities Group plc (LSE: LAND) is the largest commercial property company in the UK and the leading British property development and investment company headquartered in central London. The firm switched to Real Estate Investment Trust status when REITs were introduced in the United Kingdom in January 2007. It is traded on the London Stock Exchange and is a constituent of the FTSE 100 Index.

The Group traces its origins to 1944, when its founder Harold Samuel purchased Land Securities Investment Trust Limited, which owned three houses in Kensington and some government stock. Further acquisitions followed shortly afterwards and from 1947 the company concentrated on commercial property. In the early days some non-UK investments were acquired, but in 1971 these were sold off and the company has concentrated solely on the UK market since then. The company name was changed to Land Securities plc in 1982. After buying Trillium in 2000, it formed a 50/50 JV company Telereal in 2002 with William Pears Group (WPG) to buy the property portfolio of British Telecom. After selling its shares in Telereal to WPG in 2007, Land Securities sold Trillium to WPG in 2009.
