About Us (Semperian's History)

Semperian PPP Investment Partners Group Limited (“Semperian”) was launched in October 2007, with the initial acquisition of a £1.0bn portfolio of infrastructure assets from Land Securities plc.  Semperian provides its investors with access to a large, diverse portfolio of mature PPP infrastructure investments with long term inflation linked returns, matched to investors’ long term liabilities.

Although Semperian was formed in 2007, the group's origins date back to 2001. A brief history of the company can be found in the links below:
