This part of the Report considers the value for money of the New Accommodation Programme. The PFI deal broadly displays the potential benefits and disbenefits of other Government headquarters PFI deals. As regards the cost to GCHQ, the extent of competition before the preferred bidder was selected provides some reassurance on the price of the PFI deal. Limited further reassurance on the costs of the Programme as a whole is provided by GCHQ's Public Sector Comparator, which indicated an apparent cost saving of £71 million from the deal as compared to its realistic alternative at that time and taking into account the high costs of technical transition which had by then emerged. The PFI deal also offered significant specific benefits to GCHQ's working practices and environment compared to the conventionally financed alternative. In addition, subsequent to the choice of preferred bidder, work by its advisors gave GCHQ some assurance that the signed deal was good value. GCHQ considers that the high technical transition costs, which had been significantly understated initially, were inevitable whatever the adopted accommodation solution.
