Similarly, certain facilities management contractors provide similar services to a number of PFI projects and should be able to generate economies of scale. For the public sector to share in the benefits of these economies of scale there needs to be strong competition both in the letting of PFI contracts and in subsequent market testings of ongoing services. It remains to be seen what effect, if any, the growth in investors and contractors building up portfolios of interests in PFI projects has on these competitions and the resulting value for money of the service provision.
