UK launches public consultation on Heathrow third-runway decision framework, targeting final planning approval in 2029

The UK government has opened a 10-week public consultation on the policy framework for decisions about a proposed third runway at London Heathrow. The process is intended to feed into a final planning decision in 2029, alongside assessments of economic growth, climate targets, air quality and noise impacts.

Briefing

What Hype is tracking

A third-runway framework is now moving from planning debate toward a formal decision path, shaping the investment and operating assumptions airlines and airport users will make well before the 2029 approval target.
The consultation explicitly ties expansion criteria to economic growth, climate targets, air-quality constraints and noise—issues that have already been driving Heathrow policy, pricing and regulatory friction (see Heathrow third-runway blueprint and CAA tentatively lets Heathrow recoup up to £320m in 2027–28 fees).
The UK’s runway decision will compound Heathrow’s capacity and demand dynamics, including recent evidence of passenger traffic variability amid external shocks (see Heathrow passenger traffic slips 5% in April).
