The Department for Work and Pensions (DWP) does not own any land as DWP has outsourced estate via a private finance initiative (PFI) contract known as Prime whereby the entire DWP estate was sold (freehold, feuhold and long lease interests) or transferred (short leasehold interests) to Land Securities Trillium. The proceeds were released to HM Treasury in April 1998 (for the original DSS estate) and further in December 2003 when Prime was expanded to include the former Employment Service estate.
