BusinessLDN welcomes the opportunity to respond to the Civil Aviation Authority’s Working Paper on Regulatory Models for Heathrow Expansion. This response reiterates our support for Heathrow’s expansion, including a third runway, as an important driver of connectivity and economic growth across the UK. We emphasise the importance of a stable and predictable regulatory framework that can support long-term private investment and timely delivery, and suggest that targeted evolution of the existing Regulated Asset Base model offers the most proportionate and effective way to achieve these objectives.
