Gatwick second runway given green light as £2.2 billion project aims to boost UK economy and jobs

The government has approved Gatwick Airport’s £2.2 billion plan to build a second runway, a transformative project set to create an additional 14,000 jobs and increase capacity by 100,000 flights per year. The expansion, now officially backed by Transport Secretary Heidi Alexander, is privately financed and positions Gatwick to play a far larger role in Britain’s connectivity, trade, and tourism.

Under the plans, Gatwick will shift its emergency runway 12 metres north, enabling it to handle departures for narrow-bodied aircraft such as the Airbus A320 and Boeing 737. The airport estimates the investment could generate up to £1 billion in extra economic activity. Industry supporters and government officials describe the move as a vital engine for economic growth, potentially operational by 2029, and argue that it addresses key business constraints in the region.

Confirmation of the expansion follows extensive adjustments to address previously raised noise, environmental, and transport concerns. Noise mitigation remains a priority, with offers to impacted residents that include financial support for home improvements such as triple glazing, as well as covering moving costs in some cases. The government has also set targets to increase the share of passengers travelling by public transport, with an emphasis on easing the environmental footprint, though these targets are not legally binding.

Environmental and community groups have voiced strong opposition, outlining potential risks to climate targets and local infrastructure. Organisations such as Friends of the Earth and local campaigners warn of increased emissions, noise pollution, and strain on existing resources. A legal challenge may yet materialise, as environmental campaigners point to the need for Gatwick to pay for necessary local infrastructure improvements, including wastewater treatment.

The government maintains that the airport’s expansion can proceed without breaching the UK’s climate commitments. Officials have stated all requirements for mitigation and compliance have been included within the approval process, with Parliamentary reforms planned to simplify future infrastructure decisions. Shadow Transport Secretary Richard Holden echoed support for the project’s economic potential, while calling for prudent oversight and timely delivery.

Meanwhile, the larger Heathrow expansion is still under review, with its £50 billion third runway proposal expected to create 100,000 jobs and accommodate an additional 750 daily flights. The debate over airport expansion continues, centring on the balance between economic growth, environmental responsibility, and Britain’s standing in the global marketplace.
