Gatwick airport’s £2.2 billion expansion secures approval for second runway

Gatwick Airport has received government approval for its £2.2 billion expansion project, marking one of the UK’s most significant aviation developments in recent years. The decision, announced by Transport Secretary Heidi Alexander, allows the airport to reposition its emergency runway 12 metres to the north, enabling it to operate alongside the main runway. The upgrade will support narrow-body aircraft, such as the Airbus A320 and Boeing 737, and is expected to accommodate up to 100,000 additional flights annually.

The privately financed project aims to strengthen the UK’s air capacity while aligning with the government’s “make best use of existing infrastructure” policy. Gatwick forecasts the creation of 14,000 jobs and an estimated £1 billion annual economic boost once operational.

The project’s approval followed a complex review process. Initially rejected by the Planning Inspectorate, Gatwick’s revised submission included new noise mitigation and transport strategies. These measures encourage increased use of public transport and aim to reduce vehicle congestion around the airport.

The government has stated that the project can progress without breaching climate commitments, although campaign groups continue to question its environmental implications. Critics argue that increased air traffic could challenge carbon targets and local air quality standards, while supporters emphasize its potential to stimulate economic recovery and enhance global connectivity.

The Gatwick decision reflects a broader policy shift toward expanding airport capacity in the UK. Heathrow has also revived its third runway plans, signaling a renewed emphasis on infrastructure-led growth. Gatwick’s expansion, fully privately funded, represents a major step in balancing development goals with sustainability considerations.
