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.

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

The CAA investigated an alleged breach of licence conditions by NERL's regarding its operation of the London Approach Service

The CAA found that while flight delays increased in 2016, it did not fail to take all reasonable steps to meet demand or discriminate 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, and will monitor NERL's implementation and the effectiveness of the recommendations going forward.

• CAP 1527 - Notice of Oberon investigation (March 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.
