The UK Civil Aviation Authority (CAA) has outlined its strategy for overseeing the economic aspects of Heathrow Airport Limited from 2027 to 2031.
This plan explains how the CAA will determine airport charges during this period. It aims to keep costs fair for consumers and airlines, ensuring they don’t pay more than needed.
This document sheds light on the CAA’s H8 review process. It shows how Heathrow must consider consumer needs and environmental impacts when shaping its future business plans.
Improving Heathrow Service Quality
The review encourages efficient investments that benefit travelers. It also sets goals for improving service quality. Following the airport’s closure on March 21, 2025, the CAA will closely examine rules to strengthen Heathrow’s resilience.
In a separate move, the CAA has informed the aviation industry about a distinct review. This will focus on the economic regulation framework tied to Heathrow’s capacity expansion, including the third runway project.
The review will explore ways to ensure the regulatory system motivates cost-effective delivery of this major expansion. It will also prioritize protecting consumer interests.
The CAA plans to align this work with the H8 review, ensuring Heathrow’s economic oversight supports sustainable growth.
This approach offers flexibility for the capacity expansion timeline. It aligns with the UK government’s efforts to boost airport capacity.
The CAA expects Heathrow and airlines to maintain open, productive discussions during this process. Heathrow must submit its H8 business plan by July 2025. The CAA will evaluate it based on today’s guidance and the business plan incentive.

Review of Recent Heathrow Shutdown
Apart from these reviews, the CAA is actively engaging with Heathrow about the recent closure. The regulator is collaborating with the National System Energy Operator’s investigation into the incident.
It will consider the findings from this review, as well as Heathrow’s own investigation, to decide if further action is needed under Heathrow’s operating licence.
The CAA’s approach balances consumer protection with the need for efficient investment. By setting clear expectations, it ensures Heathrow can plan effectively for the future.

Conclusion
The H8 review emphasizes affordability and service quality, while the capacity expansion review tackles the challenges of growth. Together, these efforts aim to create a stronger, more reliable Heathrow.
Travelers and airlines alike stand to benefit from this framework. The CAA’s focus on resilience reflects lessons learned from the March closure.
Meanwhile, the push for sustainable expansion supports long-term growth without overburdening consumers. Heathrow’s business plan will be a key piece of this puzzle, and the CAA’s oversight will ensure it meets the mark.
In short, the CAA is laying the groundwork for a fair and forward-thinking Heathrow. Its dual reviews address both immediate needs and future ambitions. By fostering collaboration and setting firm guidelines, the regulator is steering Heathrow toward a balanced, consumer-friendly future. As the July 2025 deadline nears, all eyes will be on Heathrow’s next steps.
