The steps taken to address concerns with PFI include the abolition of PFI credits, the introduction of new integrated assurance and approval arrangements, the publication of the WGA and the commitment to deliver £1.5 billion savings from operational PFI projects. In response to the changes in economic conditions, initiatives taken include co-lending to support PFI projects, increased capital contributions phased-in during the construction period to improve affordability and the UK Guarantees programme.
