15. Soft facilities management (also known as soft services) generally relate to the day-to-day supporting services such catering, cleaning, security etc. that support the operation of an asset. There is no a priori reason why a PFI scheme should or should not include soft services. The Treasury have introduced a strengthened soft FM test with the aim to challenge further the assumptions the public and private sector utilise for VFM assessments regarding the inclusion of soft FM in PFI. The emphasis for both procuring authorities and the private sector is, at all stages, to provide robust evidence in support of all elements of the VFM assessment. As procuring authorities decide which particular soft services are most important for different projects, so should there be strong evidence provided as to how the benefits associated with the chosen procurement route for each will actually be realised. The detailed methodology for the soft services test is set out in paragraph 4.8.
