1 A Public Sector Comparator (PSC) is an estimate of what the project would cost if traditional procurement methods were used but still meeting the performance standards expected from the private sector deal over the life of the contract. The PSC is normally used to determine whether private finance offers better value for money than traditional procurement.
2 The PSC for the Home Office accommodation project was originally developed in 1998 when the envisaged solution was refurbishment of the existing Home Office estate. The financial advisers on the project, PricewaterhouseCoopers, were responsible for development of the second PSC which represents the whole life cost of central London accommodation at 2 Marsham Street under a conventional procurement process.
