• Considerations

    Our proposals are based on extensive consultation, research and testing around the potential impacts and benefits of the scheme. Our technical work confirms that it will be less damaging to the environment, less disruptive to local communities and provide opportunities for noise mitigation.



No significant new communities under flight path.

By extending an existing runway we maintain current flight paths and no significant new communities are brought into the airport’s existing noise footprint. For those existing communities within the footprint, we are committed to developing innovative noise reduction tactics.

As many as 260,000 additional slots could become available by extending the runway, enabling alternate approaches, respite periods for local communities and an opportunity to reduce night quota flights. Crucially, during the critical early morning period, arriving aircraft could land 2.5 miles further west on the new runway extension, moving the entire noise footprint and reducing sleep disturbance for many West London residents.

Absolute aircraft noise is being reduced as modern aircraft are able to meet even more restrictive noise criteria. There are also a number of aircraft and air traffic control operating techniques we can employ that make it possible to change the frequency of concentrated noise, and to provide respite in noise frequency by changing routes.



Our proposed safety zone is 650m, more than twice the length required by international regulations.

As our runway proposal is a relatively new concept, we have completed a thorough independent safety review with aviation experts and the CAA has conducted its own preliminary safety review.

Our independent review concludes that our proposal is safe and efficient and complies with all relevant regulatory requirements.



Local communities


Less land required than other options.

The nature of our proposal to simply extend Heathrow’s northern runway to the west means that far less land is required than any other option. This has significantly less impact on the local area than other proposed options. By developing an existing runway we would be in effect using the same flight paths so no significant new communities would be brought into Heathrow’s noise footprint.

The main impact would be on commercial property in the Poyle industrial area. We are committed to keeping the number of nearby residential properties affected to an absolute minimum. The fact that our scheme is lower in cost than others means there would be more headroom for generous compensation for those people affected by expansion.



Better connectivity, less congestion.

The UK’s road networks will only become more congested over the next 30 years and as a result, less reliable with longer journey times for passenger and employees. Our surface access proposals connect Heathrow with all major rail and road networks. For the first time, there would be direct rail access to the airport from the west and south, transforming accessibility and providing an attractive alternative to the car.




Heathrow expansion would underpin UK economic growth.

Minimising the cost of airport expansion and protecting the UK’s economic competitiveness are key considerations. Considerably cheaper than other solutions, the Airports Commission estimated our proposal would boost the UK economy by up to £214bn and create up to 164,000 new jobs nationwide. It is vital that the benefits of expansion are felt throughout the UK, and our surface access proposals ensure that the regions would feel the positive social and economic impacts of enhanced connectivity.
