Nationally Significant Infrastructure Projects regime: operational review

Minister of State for Housing Christopher Pincher MP launched an operational review of the NSIP regime as part of a speech at the National Infrastructure Planning Association (NIPA) summer conference on 7 July 2021.

The operational review forms part of the National Infrastructure Planning Reform Programme. In advance of his speech, Minister Pincher wrote a letter to NIPA members introducing the reform programme and setting out how important it will be for all those who use or interact with the NSIP regime to work together to make the operational review a success.

See the Annex to the Minister’s letter for further details of the National Infrastructure Planning Reform Programme and a road map of reforms.
