Condition 10 of NERL's licence requires it to provide a business plan, service and investment plan and periodic reports. After consultation we modified Condition 10 to require NERL to produce detailed technology and airspace plans for RP2 (2015-19) and outline programmes for RP3 (2020-24) as well. At the same time we removed the requirement for it to produce plans on raising the UK transition altitude (TA) and the implementation of the London Airspace Modernisation Programme (LAMP). Our consultation documents, as well as previous documents relating to Conditions 10 and 10(a) are below:

In our Ad Hoc Review of NATS-related risks in 2012/13, we found that the current arrangements for governance and ring-fencing may need to be strengthened to ensure that users are adequately protected from risks which arise outside of the regulated business.

We consulted on initial proposals to modify these arrangements, and have now published our decision to modify NERL's licence.

• CAA approval letter
• NERL Code of Practice

Investigation under Section 34 of the Transport Act 2000: Project Oberon

The CAA has published preliminary finding of an investigation into an alleged breach of licence conditions by NATS En Route (NERL). The investigation followed the receipt of complaints regarding the performance of NERL's operations in managing the London Approach Service.

The CAA has investigated the matter and while flight delays did increase in 2016 compared with previous years, the CAA has preliminarily found that NERL did not fail to take all reasonable steps to meet demand. The investigation also found that NERL has not discriminated against any party in delivering the London Approach Service. The CAA has made a number of recommendations to NERL to ensure it improves its contingency planning and the resilience of its operations in the future.

The CAA is now awaiting representations from interested parties after which it will consider whether or not to confirm its preliminary findings.

• Notice of investigation
• Preliminary findings for consultation until 16:00, 23 May 2017

Information on the CAA's concurrent powers with the Office of Fair Trading under the Competition Act 1998 and part 4 (market investigations) of the Enterprise Act 2002 is available on the  Competition powers page.

This discussion document seeks stakeholder views on the CAA's proposed strategic themes for the future regulation of NERL, in order to inform the development of the CAA's approach to the regulation of NERL from 2020.
