PR14 feeder models (updated 12 September 2014)

We have developed a range of feeder models to provide data to the financial model in the form that it requires to determine price controls and help assess financeability. Apart from the wholesale initial baseline feeder model and the risk assessment tool, these feeder models all sit between the company business plan and data submissions at one end and the financial model at the other.

The feeder models are used in different ways, for example to:

  • re-arrange data to match the financial model’s requirements,
  • compare companies’ and our views of costs and recording of assessments
  • allow companies’ proposed metrics to be adjusted

You can find a diagram showing the models and how they fit together below. Clicking on any of the boxes will take you to a description of that particular model. Within the model description you will find a link to a blank version of the model.

For reference, we have also published some populated models on the National Archives website.
