The poor management of private finance contracts is leading to low-quality assets being handed back to the government, such as schools and hospitals, as noted by the public accounts committee (PAC).
PFI deals have been a controversial way to build public projects without adding to the national debt, but concerns persist over the value for money they provide.
MPs are recommending major changes to ensure careful management of PFI contracts and compliance with obligations by private sector firms to avoid issues when contracts expire.
The PAC is urging the government to provide a comprehensive framework for sharing risks between public and private sectors, along with detailed information on future infrastructure projects to attract new investors and drive competition.
