Our NR23 business plan sets out how we will continue to provide good service quality to our customers across a range of traffic levels at a cost-effective price so that we are not a brake on recovery. We have listened carefully to feedback we received from our customers, responded to requests for change and taken direction on the options we presented.

Alongside the plan we have published a number of appendices, containing extensive additional data and other information to support our proposals. We look forward to engaging with the CAA about the plan in the coming months.

The highlights

  • A safe and efficient air traffic system: Supporting flights that exceed 2019 levels in 2027 by up to 15% at an efficient service performance level
  • Supporting the industry’s recovery: Underlying unit cost similar to 2019 at around £52 (2020 prices) and the deferral of 2020-22 revenue shortfalls recovery and profiling prices
  • Meeting net zero ambitions: Enhanced environmental and fuel benefits, consistent with industry targets to achieve net zero emissions by 2050, and increased societal expectations on aviation
  • Advancing airspace modernisation: To improve environmental performance and accommodate future traffic growth, supported by our technology transformation programme
  • Operational resilience: Develop and train the next generation of air traffic controllers to mitigate expected retirements, safely meet projected demand and provide further operational resilience
  • Appropriate financial resilience: Protection against a slower recovery or future traffic/economic shocks, essential for maintaining critical national infrastructure
