Heathrow Airport Expansion

Deirdre Costigan Excerpts

Tuesday 20th October 2026 Westminster Hall

[Simon Lightwood]

I will make a bit of progress, if the hon. Member does not mind. We are a bit short on time.

I may not be able to respond to every question raised during the debate, as the Government are currently considering the consultation responses, and parliamentary scrutiny of the draft Heathrow expansion national policy statement—or HENPS—remains ongoing. It would not be appropriate to pre-empt those processes or prejudge any future decisions while that work remains under way. However, I will ensure that hon. Members receive responses in due course to any points that I am unable to cover.

This Government recognise Heathrow’s critical role as the UK’s only hub airport, connecting businesses and passengers to global markets and supporting trade, tourism and investment across the country.

Will the Minister give way?

[Simon Lightwood]

I am still going to make a bit of progress; I have limited time, and I want to reply to the points raised.

Hon. Members will be aware that the Government published the draft HENPS consultation in June. That set out the proposed planning policy framework for expansion and the requirements that any future scheme would need to meet, including the Government’s four tests on economic growth, climate change, air quality and noise.

As I have noted, we are carefully considering the more than 27,000 responses received and will also consider the recommendations of the Transport Committee. Any finalised HENPS would also be subject to parliamentary consideration, including a debate and a vote in the House, before it could have legal effect.

The draft HENPS does not grant development consent for expansion. Only when a national policy statement has been designated can proposals for a development consent order be brought forward. Any future proposal by a promoter of expansion would still need to progress through the statutory development consent order process and demonstrate that it met the requirements of the relevant policy framework. It is for potential promoters to determine the timetable and sequencing of their proposals, and for the Government to put the right frameworks in place. Any potential promoter bringing forward a scheme of this scale and complexity will need to balance pace with deliverability, affordability and value for money for passengers.

Given the current stage of the consultation process and the ongoing period of parliamentary scrutiny, I will not seek to pre-empt those processes, and my remarks today should be considered in that context. The Government will provide a more substantive update to the House once we are in a position to do so. That said, I will address some of the points raised during today’s debate where I can.

--- Later in debate ---

[Simon Lightwood]

I am sure that the Aviation Minister will have heard the hon. Gentleman’s message and will be delighted to respond to him.

Any promoter must give evidence that expansion will deliver benefits across the country, not just locally. Analysis published alongside the draft HENPS indicates that up to 40% of the estimated GDP growth is expected to accrue in regions outside London and the south-east.

[Deirdre Costigan]

Will the Minister give way?

[Simon Lightwood]

I will, for the final time.

[Deirdre Costigan]

I thank the Minister for giving way; he is being very generous with his limited time. Many of my constituents in Ealing Southall have responded to the consultation. Noise has been a particular concern, so I hope that he will manage to make some remarks on how realistic steeper landing approaches and new aircraft technology might be in addressing noise.

I also want to talk about jobs. The Minister talks about growth. Many of my constituents work at the airport, and their worry is that if the expansion does not go ahead, we will lose our status as a hub airport and their jobs might be at risk in the future. Is the Minister able to say anything to reassure the many workers from my constituency in good-quality jobs at Heathrow airport?

[Simon Lightwood]

Once again, I am sure the Aviation Minister will have heard my hon. Friend, and I will go on to address some of those issues.

The draft HENPS introduces a new test requiring potential promoters for development consent to demonstrate, through a clear, evidence-based growth strategy, how their scheme will support economic activity and growth at national, regional and local levels.

I will move on to climate change. The draft HENPS contains a clear climate change requirement whereby any increase in carbon emissions resulting from a proposed scheme must not be so significant that it would have a material impact on the UK’s legally binding carbon budgets. For expansion to proceed, it would need to align with the Government’s climate goals, including our legal commitment to reach net zero by 2050. Any increase in carbon emissions associated with Heathrow expansion would need to be considered against the Government’s carbon reduction targets and the mitigation requirements set out in the draft HENPS.

On air quality, the draft HENPS is also clear that a scheme for Heathrow expansion must demonstrate that it will not result in any new breaches of legal obligations on air quality or make existing breaches materially worse. As part of that, the draft HENPS sets out mitigations that a potential promoter should consider to minimise the impact of the project on the environment and affected communities.

Finally, the draft HENPS sets out a noise test requiring overall aircraft noise to be limited and, where reasonably possible, reduced in comparison with 2024, taking into account quieter aircraft and operating procedures while providing adequate and predictable respite for communities. The mitigations should include a runway alternation scheme and a scheduled night flight ban. The draft HENPS currently requires an applicant to propose a scheduled night flight ban of six and a half hours, between the hours of 11 pm and 7 am, as part of their proposed mitigations of the noise impacts. Expansion would increase capacity, which may provide greater operational flexibility and allow aircraft to land more efficiently, potentially reducing reliance on extended holding patterns. That could benefit people living in the areas currently affected by noise from aircraft in holding patterns before landing.

Through the consultation, we are listening carefully to views across all four tests. However, I want to make it clear that we recognise that noise and air quality are particularly important to many local residents, and we are committed to ensuring that those concerns are fully considered as part of the process.

The draft HENPS also makes it clear that Heathrow expansion must be supported by a credible surface access strategy that enables more journeys to be made on public transport and reduces pressure on the wider transport network. The draft HENPS defines clear passenger public transport mode share targets. However, the onus will be on any potential promoter to demonstrate through the development consent order process that their proposed approach can credibly achieve those targets. Heathrow expansion is a private sector project, and the Government have been consistently clear that it must be privately financed.
