The document discusses the role of private finance in addressing infrastructure gaps and managing risks from public-private partnerships (PPPs). It notes that while the majority of capital spending is publicly financed, private finance has averaged £2.3 billion per year in investments. The National Infrastructure Plan from 2014-2021 anticipates 79% of £327 billion in investments will involve some private finance. Two-thirds of current PPP projects are in social infrastructure like hospitals, schools, and military facilities. The document also discusses state loan guarantees, financial market conditions, and allocating risks between the private sector, taxpayers, and consumers.
