National Infrastructure Assessment

Status:Analysis.  

An assessment of the United Kingdom's infrastructure needs to 2050 and beyond.

Every five years, the Commission publishes a National Infrastructure Assessment.

Each Assessment analyses the UK’s long term economic infrastructure needs, outlining a strategic vision over the next thirty years and setting out recommendations for how identified needs should be met.

The Commission is now working on the second National Infrastructure Assessment, to be published in autumn 2023.

To start the process the Commission published a Baseline Report in November 2021 which summarises the current performance of key infrastructure sectors. Use the buttons above to click through and read the Baseline Report and access the separate annexes for each sector.

The Baseline Report uses this data, alongside social research, to establish the main priorities the Commission intends to explore in the next Assessment.

These studies will focus on three key strategic outcomes:

  • reaching net zero
  • reducing environmental impacts and adapting to a changing climate
  • supporting levelling up.

The Commission held a Call for Evidence on the study topics, to inform its scoping and research phase (this has now closed).

It will continue to engage with stakeholders throughout the analysis phase and plans to hold both virtual and physical events to discuss its emerging work.

The final Assessment report and recommendations to government will be published in the second half of 2023.

For most people it’s also a decision taken when their existing heating system is at or near the end of its life. Will you keep gas central heating? Will you...
