The UK Civil Aviation Authority (CAA) has published a working paper on Heathrow’s regulatory model.
The paper, which follows the Government’s announcement on the proposal for a third runway that will be used to progress the Airport’s National Policy Statement, sets out a review of the current regulatory framework of Heathrow Airport, exploring whether an alternative model for capacity expansion could better serve consumers.

All new potential models have been developed based on submissions from stakeholders, including both Heathrow Airport Ltd and Heathrow Reimagined, and explore regulatory models used across other industries and countries.
Selina Chadha, Group Director of Consumer and Markets at the UK Civil Aviation Authority said:We recognise the importance of the efficient and effective expansion of capacity at Heathrow airport to the wider economy, airlines and consumers, and welcome the Government’s support of our review.
We are seeking to develop the regulatory framework to both deliver the best outcomes for consumers and support the Government’s timetable for the delivery of expansion.
Once responses to the paper are assessed, the CAA will publish a full recommendation for the regulatory model to be applied at Heathrow Airport around Spring 2026.
The full working paper can be found on the CAA’s website.
