London’s Heathrow Airport is set to launch a 12 and a half-week consultation on its expansion plans to gather public opinion and improve the final planning application for the project.

The consultation, which will start on 18 June and expire on 13 September, will include the organising of events in several locations, launching an extensive publicity campaign across newspapers, radio, billboards and digital medium.

Spotify will contact around 2.6 million households directly in the surrounding areas of the airport to encourage them to participate.

The consultation follows the recent ruling by High Court of Justice in London, which rejected legal challenges from environmental campaigners opposed to the construction of a third runway at London’s Heathrow Airport.

Heathrow expansion executive director Emma Gilthorpe said: “Heathrow’s expansion is a project of huge national and local significance, and it is critical to our country’s economic growth.

“An expanded hub airport will allow the country to access more of the world, create thousands of jobs locally and nationally and it will open up new trading routes.

“But we can’t deliver these plans alone. We urge everyone to have their say in this consultation, to shape our plans, and to help us deliver expansion in the fairest and most sustainable way.”

During the upcoming consultation, the airport will seek feedback on four key areas, including its preferred masterplan for expansion, plans to operate the future airport, impacts of the airport’s growth, and plans to manage the impacts of expansion.

Upon completion of the consultation and receipt of feedback, Heathrow will submit a final proposal to the planning inspectorate in 2020 to start its approvals process.

Heathrow claims that the third runway project will provide a major boost to the UK’s economy and create up to 114,000 local jobs by 2030.

“An expanded hub airport will allow the country to access more of the world.”

A new runway would boost Heathrow’s capacity from 85.5 million passengers to 130 million, and the Department for Transport previously stated that no expansion would mean London’s five airports would reach full capacity by 2034.

In April, British design and engineering firm Atkins was awarded a set of five major contracts to support the sustainable expansion programme at Heathrow Airport in the UK.

In March, London’s Heathrow Airport unveiled a list of 18 sites that qualify to host factories and yards to build components for its third runway project.
