Transport Appraisal Framework (TAF)

The Transport Appraisal Framework (TAF) provides appraisal and implementation guidance that aims to promote investment in the transport system which meets the needs of society, fulfils strategic policy objectives, and delivers value for money to develop a common framework for appraising transport investments in accordance with the Public Spending Code (PSC) .

The TAF replaces the Common Appraisal Framework (CAF) for Transport Projects and Programmes (published in 2016 and updated subsequently).

The changes facilitate the delivery of transport investment proposals through rigorous and proportionate appraisals, in compliance with PSC requirements, and by making the appraisal framework more accessible and user-friendly. It is designed to help assist and guide Sponsoring Agencies when developing transport business cases for proposed public investment.

In June 2023, this Circular formally announced the publication of the TAF and identifies the main changes made.

This guidance takes effect immediately and should be followed by Sponsoring Agencies when submitting appraisal documentation to the appropriate Approving Authority.
