Tribunal confirms legality of Welsh Government’s Cardiff Airport subsidy package

The Welsh Government has secured approval for a £205m subsidy package for Cardiff Airport after a legal challenge brought by Bristol Airport was dismissed by the UK’s Competition Appeal Tribunal.

The subsidy, first approved by Welsh ministers in April 2025, is intended to be distributed over a 10-year period and forms part of a wider strategy to support Cardiff Airport’s long-term development. According to a written statement published by the Welsh Government, the package includes funding for infrastructure improvements such as maintenance and repair facilities, cargo handling capacity, and passenger service upgrades, as well as support for new and existing air routes.

The Welsh Government referred the proposed subsidy to the Competition and Markets Authority during the approval process, as required under UK subsidy control rules, before finalising the scheme following consultation and review. Officials said the investment was designed to support economic growth, connectivity and employment linked to aviation and aerospace activity in Wales.

Bristol Airport challenged the decision, arguing that the level of public support given to Cardiff Airport distorted competition between the two airports and breached subsidy control principles. It also claimed that repeated public funding for the airport represented an unfair market advantage and raised concerns about the impact on private operators in the region.

However, the Competition Appeal Tribunal rejected the challenge, ruling that the Welsh Government had acted within its legal powers and had appropriately assessed the subsidy under the statutory framework. Legal commentary on the judgment indicates the tribunal found that public authorities have broad discretion when applying subsidy control principles, provided their decision-making process is properly evidenced and rational.

The tribunal’s ruling confirms the legality of a package. The decision follows years of ongoing debate over the airport’s financial performance and its reliance on public funding since being acquired by the Welsh Government in 2013.

Cardiff Airport has continued to operate at a loss in recent years and has faced ongoing challenges in restoring passenger numbers to pre-pandemic levels, while supporters of the investment argue that public ownership is necessary to maintain Wales’s direct international connectivity and support regional economic development.
