London’s Heathrow Airport has planned to launch an eight-week public consultation in a bid to finalise its airport expansion proposal after the UK’s aviation regulator CAA limited early spending on the project.

Due to the limit on expenditure, the construction of the third runway was extended. The airport is now required to revise the modelling of the plan to show that the targets of the Airport National Policy Statement (ANPS) can be met.

The public consultation will begin in April and conclude in June this year.

Heathrow will also launch correspondence with local authorities to gather their feedback on the process. The received responses will then be included into the final planning application.

The application, which will be submitted to the Planning Inspectorate before the end of the year, will outline how the airport’s expansion plans to meet the country’s growth and adhere to ANPS requirements.

Heathrow will also detail the measures it will adopt to meet environmental targets, generate high-skilled jobs and honour commitments made to local communities.

The third runway is expected to start operations between 2028 and 2029 based on approval from the Secretary of State.

Heathrow executive director for expansion Emma Gilthorpe said: “This country is ready for a decade of infrastructure delivery underpinned by expansion at Heathrow. We are keen to ensure our plans continue to be supported and shaped by local people as we prepare to deliver the economic boost Britain needs.”

In 2017, Heathrow Airport launched a public consultation to mitigate the environmental impact of the proposed third runway.
