Building Schools for the Future Investments LLP (BSFI) is a limited liability partnership whose members are the Department for Education and Partnerships UK. BSFI is the sister organisation to PfS, and is the central investor in the BSF programme.

There are inherent conflicts of interest between investment and procurement, so PfS does not participate in the management of BSFI, which is undertaken through its Management Board and Investment Committee. Similarly, BSFI does not participate in the process of procuring a Selected Bidder for BSF.

BSFI's objectives are to ensure that the BSF programme's goals are delivered and that a financial return is generated for its members.

BSFI invests in 10% of the risk capital of each Local Education Partnership (LEP) alongside the local authority and its chosen private sector partner. A similar investment will also be made in any Strategic Partnering Vehicles (SPVs) that are established by the LEP to deliver PFI projects. BSFI will be represented on the boards of all companies in which it invests. It will facilitate partnership between the public and private sectors and ensure that best practice is identified locally and nationally and is communicated across the programme.
