The UK government has published a blueprint for a third runway at London Heathrow, a move that could eventually expand air cargo capacity at one of the world’s busiest airports, but remains subject to consultation and planning approvals.
Transport Secretary Heidi Alexander launched a consultation on the renamed Heathrow expansion national policy statement (HENPS), describing expansion of the airport as 'critical to national growth'. The draft policy sets out the conditions needed for the project to be given the go-ahead.
Two Proposals on the Table
Heathrow Airport Limited (HAL) wants to build a full-length, 3,500-metre runway, which would require the M25 motorway being moved. The scheme is estimated to cost £33bn, including £1.5bn to move the M25, and is expected to be fully privately financed. It would increase Heathrow's capacity to 756,000 flights and 150 million passengers a year.
Tycoon Surinder Arora, who specialises in providing rooms for aircrew near airports, wants his company to install a 2,800-metre runway that would not involve moving the motorway.
| Proposal | Runway Length | Cost | M25 Impact | Capacity (flights) | Capacity (passengers) |
|---|---|---|---|---|---|
| HAL (Heathrow Airport Limited) | 3,500 metres | £33bn | Requires moving M25 (£1.5bn) | 756,000/year | 150 million/year |
| Surinder Arora | 2,800 metres | Not stated | No motorway move | Not specified | Not specified |
In November last year, Alexander announced her preference was for a full-length runway.
Conditions and Constraints
The draft HENPS requires applicants to demonstrate how the transport network would accommodate increased passenger numbers, including any necessary road and rail improvements. Expansion must be compatible with the UK's legally binding climate targets, must not cause new breaches of air quality limits, and must ensure noise emissions are not worse than 2024 levels, with reductions where possible.
Chancellor Rachel Reeves said she was determined to get 'spades in the ground' for the third runway, and for it to be built by 2035. She claimed Heathrow was currently 'not punching its weight' as a hub airport, and argued that Heathrow was 'the perfect example of the problem in the UK in being able to get stuff done', with people knowing 'for years, decades' that a third runway was needed but failing to build one.
Reactions
Heathrow chief executive Thomas Woldbye said he 'strongly welcomed the government has taken this next critical step'. He added: 'The UK cannot realise its full economic potential without an expanded Heathrow and this is an important step towards delivering the capacity the country needs. We will now focus on securing planning permission and delivering this vital project.'
Alethea Warrington, head of aviation at climate charity Possible, said the government was 'living in a fantasy land if it thinks it can allow a new runway without making noise pollution even worse, making our air even more toxic, or crashing through our climate targets.'
Implications for Freight Forwarders
While the blueprint focuses on passenger capacity, air cargo operations at Heathrow could benefit from expanded runway and flight slots. Freight forwarders should monitor the consultation process, which will shape how the airport handles future cargo volumes. The requirement to improve road and rail links may also affect trucking and intermodal connections to and from the airport. However, the climate and noise conditions could limit night-time operations, which are critical for time-sensitive air freight. The government’s stated goal of 'spades in the ground by 2035' suggests a long timeline, meaning any capacity boost is years away. For now, forwarders should assess how the existing constraints (air quality, noise) might tighten before expansion is approved.
Watch List
- Consultation period: Responses to the HENPS draft will influence final policy.
- Planning permission: HAL must submit a detailed application; legal challenges from environmental groups are likely.
- Infrastructure spending: Road and rail upgrades around Heathrow will affect access for cargo trucks.
- Climate litigation: The compatibility with UK climate targets could be tested in court.
