The critical national infrastructure

The national infrastructure comprises the facilities, systems, sites and networks necessary for the delivery of the essential services upon which daily life in the UK depends.

If the national infrastructure were to suffer severe damage, disruption or loss, the country would have difficulties functioning socially and economically.

There are nine national infrastructure sectors which provide these essential services:

  • Communications
  • Emergency Services
  • Energy
  • Finance
  • Food
  • Government
  • Health
  • Transport
  • Water

Some elements of the national infrastructure are more critical to the delivery of essential services than others. CPNI works with the national infrastructre operators and with lead government departments to identify critical national infrastructure (CNI) within the sectors.
