The CAA undertakes economic regulation of airports and NATS (En Route) plc (NERL). This page focuses on airport regulation. Information on regulation and licensing of NERL can be found here.
We provide information to prospective and current investors at Heathrow and Gatwick airport on the Investors page.
Economic regulation of airports
We assess whether airport operators have substantial market power and, where appropriate, licence those that do. Airport economic licences include conditions on price controls, specifying the quality of the services the airport operator must deliver and how much it can charge from them.
We issue certificates to airport operators that meet the statutory requirements to be classed as Statutory Undertakers.
We declare the hours of peak congestion at Heathrow and Gatwick under the Traffic Distribution Rules.
Market power assessments
In January 2014, we determined that the operators of Heathrow and Gatwick met the market power test set out in the Civil Aviation Act 2012 and therefore required a licence to recover charges for its services. We found that the operator of Stansted did not meet the test for services to either passenger and cargo airlines and therefore did not require a licence.
In February 2014, we granted licences to the operators of Heathrow and Gatwick which came into force on 1 April 2014. These licences include conditions relating to prices, service quality and operational resilience, amongst others. More details are on the economic licensing of Heathrow and Gatwick pages.
We have powers under the Civil Aviation Act 2012 to impose penalties for breach of a licence condition or breach of an enforcement order issued in relation to a licence condition. We may also impose penalties for non-compliance with information notices we have issued and for destroying information or knowingly supplying false information. We are required to publish a statement of policy on penalties for non-compliance under Chapter 1 of the Civil Aviation Act 2012 setting out the criteria we will use to determine whether a penalty is appropriate and the amount of any penalty.

In May 2015, after consultation, we published Economic Licensing Enforcement Guidance covering our approach to enforcing the airport economic licences and licences to provide air traffic services under the Transport Act 2000. The guidance outlines the legal framework in which our work fits and informs stakeholders of the enforcement powers we have and how we will use them.

After consultation, we also published prioritisation principles that explain our approach in deciding which pieces of work to take forward in the areas of consumer protection, competition law and economic regulation.
Latest price control reviews
Since we started price regulating airports in 1986, we have completed six price control reviews.
The current control period (referred to as Q6) started on 1 April 2014 for both Heathrow and Gatwick, and will run until 31 December 2019 (price control extended by one year in 2016) for Heathrow and 31 March 2021 for Gatwick. You can view our work on the Q6 reviews, including the price controls and other licence conditions, on our economic licence pages for Heathrow and Gatwick.
We are currently reviewing the regulatory arrangements at Heathrow.
Previous price control reviews
- Q5 (2008-2014) price control of Heathrow, Gatwick and Stansted
- Q4 (2003-2008) price control of Heathrow, Gatwick, Stansted and Manchester
An airport operator whose annual turnover at the airport exceeded £1m in at least two of the last three financial years may apply for a certificate that confers rights on the operator as a statutory undertaker. Airport operators who already have a permission to levy airport charges issued under section 39 of the Airports Act 1986 retain their status as a statutory undertaker.
