Heathrow Airport expansion

Why does there need to be an expansion of Heathrow Airport?

Heathrow Airport is operating at capacity today, and London’s airports are expected to be at capacity by the mid-2030’s. This strain on capacity could lead to issues involving flight delays, unreliability and poor domestic connectivity. As a result, in 2012, the Government established the Airports Commission which identified the need for increased airport capacity in London and the South East of the UK.

Will the terminal be integrated to be part of Heathrow Airport?

Heathrow Airport currently has four separate terminals (Terminals 2, 3, 4 and 5) in use and requires additional terminal capacity to cater for the expected increase from 54 million passengers to 130 million passengers per year. Our proposal focuses the integration of new passenger facilities with Terminal 5.

How will the two projects work together and how will you manage combined impacts with the Heathrow Airport Limited’s scheme and other major construction projects?

The Heathrow West and Heathrow Airport Limited projects are currently being developed in parallel, but they will be submitted as two separate, and competing, DCO applications. We recognise that there are connections between the projects as both include components of the NRS.

A key component of the environmental impact assessment is the consideration of cumulative impacts. This will include identifying and describing the cumulative effects of the Proposed Development and the Heathrow Airport Limited project.

The cumulative effects assessment will also seek to provide information on how Heathrow West’s proposal would combine or interact with the effects of other developments such as large residential schemes or other transport projects.

How can another organisation work within Heathrow Airport Limited’s expansion project?

Advice published by the Civil Aviation Authority (CAA) in August 2018 confirmed that separate terminal development and operation was possible within the regulatory framework.  The Airports National Policy Statement also recognises that there can be more than one promoter of the development necessary to deliver the expansion of Heathrow. The principles of competition are also strongly supported by the CAA.

The cargo terminal at Heathrow Airport is already operated by SEGRO and this multi-operator model is an established international principle.
