CAP1914 Economic regulation of Heathrow: programme update, April 2020



CAP1914 provides an update on our programme for the development of the economic regulation of Heathrow Airport Limited (“HAL”) in the light of the very significant uncertainties brought about by:

  • the severe impact of the Covid-19 pandemic on the aviation sector as a whole and passenger numbers at Heathrow airport;
  • the Court of Appeal's decision setting aside the Airports National Policy Statement; and
  • HAL's subsequent decision to stop its programme for expanding Heathrow airport.

It outlines our proposals for changing our overall approach to developing the regulatory regime for HAL in the light of these developments.

CAP1852 Economic regulation of Heathrow Airport Limited from January 2020: notice of licence modifications, November 2019



CAP1852 gives notice under section 22(6) of the Civil Aviation Act 2012 ('CAA12') of the CAA's decision to modify Heathrow Airport Limited's (HAL) Licence granted under section 15 CAA12. The modifications that the CAA has decided to make are to:

  • extend the current price control by a two year interim period, up to 31 December 2021, taking account of the commercial arrangements between HAL and certain airlines for this period;
  • include a new licence condition to promote economy and efficiency by HAL in the operation, maintenance and development of Heathrow airport; and
  • make minor changes to update the price control arrangements, remove obsolete terms and make a change to HAL's regulatory audit requirements to reflect current auditing guidelines.

The decision on these licence modifications follows on from the notice issued by the CAA under section 22(2) of CAA12 in August 2019 ('the August 2019 Consultation'), which built on the CAA's consultations on interim price control arrangements in February 2019 ('the February 2019 Consultation') and April 2018 ('the April 2018 Consultation') and its consultation on the regulatory framework to support capacity expansion at Heathrow in March 2019 ('the March 2019 Consultation').

CAP1847 Economic regulation of Heathrow Airport Limited: an update on the CAA surface access policy, October 2019



CAP1847 follows on from the consultations that we published on the regulatory framework to support capacity expansion at Heathrow airport in January, June and December 2017 and April and October 2018. It provides an update of our policy on the surface access costs that Heathrow Airport Limited (“HAL”) should be allowed to recover from airport charges.

As noted above we have consulted a number of times on surface access policy and now regard the high-level policy as set out in this paper as settled. Nonetheless, we will consult where appropriate on the application of this policy to projects or groups of projects that HAL brings forward for funding under these arrangements (and if the application of this policy were to reveal unexpected difficulties we do not rule out consulting further on the underlying policy).

CAP1832 Economic regulation of Heathrow: working paper on financial resilience and ring fencing, August 2019



CAP1832 focuses on options the CAA is considering to provide further assurance that Heathrow Airport Limited (“HAL”) operates in a financially resilient manner and that risks to consumers arising from financial distress are appropriately mitigated while not cutting across the financing arrangements HAL already has in place to support its regulated business. It considers options for possible changes to the financial resilience and ring fencing provisions in HAL's licence that may be appropriate, in particular, given the scale and challenges of the development of new capacity at Heathrow airport. It develops further the thinking we set out in our consultations on the regulatory framework to support capacity expansion at Heathrow in June and December 2017.
