Slough, Hillingdon, and Hounslow Align Around Heathrow Expansion at UKREiiF

At this year’s UK Real Estate Investment & Infrastructure Forum one of the most significant themes emerging from discussions around a potential third runway at Heathrow Airport was the growing alignment between neighbouring boroughs.

Representatives and stakeholders connected to Slough, Hillingdon and Hounslow discussed the importance of ensuring that any future expansion delivers meaningful and shared outcomes across all three boroughs particularly for residents who have historically experienced economic disadvantage under investment and limited access to opportunity.

While Hillingdon is widely regarded as the principal catchment borough for Heathrow due to its direct geographic relationship with the airport, the wider economic and employment ecosystem extends beyond a single local authority boundary. Discussions at UKREiiF reflected increasing recognition that Heathrow’s influence and the benefits associated with expansion should be distributed more equitably across neighbouring communities.

A Shared Regional Opportunity

The discussion was framed around more than aviation growth alone. Contributors focused on how major infrastructure investment could support wider social and economic renewal across West London and the Thames Valley corridor.

Key themes included:

• Long term employment opportunities for local residents

• Skills development and apprenticeship pathways

• Increased delivery of affordable and social housing

• Investment into communities experiencing deprivation

• Regeneration of underutilised areas

• Supporting residents into sustainable employment

• Reducing poverty and improving social mobility outcomes

Delegates repeatedly emphasised that the success of a third runway should not be measured solely through passenger growth or international connectivity but through tangible improvements to quality of life for surrounding communities.

Audience Participation and Wider National Relevance

The discussion focused on the principle that major infrastructure investment should create direct and measurable benefits for local communities including access to employment housing infrastructure investment education and skills development.

There was broad agreement that communities most impacted by major infrastructure projects should also be among the principal beneficiaries of long term economic growth associated with those developments.

Contributors also discussed how a coordinated approach between local authorities strategic partners education providers and the private sector could provide a framework capable of being replicated nationally particularly in areas surrounding major transport and infrastructure assets.

Collaboration Between Boroughs

A notable feature of the discussion was the collaborative tone between boroughs. Historically conversations relating to Heathrow expansion have often centred on competing priorities planning pressures and environmental concerns. However dialogue at UKREiiF suggested an increasingly coordinated approach may now be emerging.

Rather than competing for investment, Slough, Hillingdon and Hounslow appear increasingly aligned around the principle that regional growth should deliver inclusive outcomes across borough boundaries.

There was also recognition that long term regeneration requires coordinated planning between local authorities, transport bodies, education providers and commercial stakeholders in order to maximise economic and social value for residents.

Beyond Infrastructure Delivery

The wider message emerging from discussions at UKREiiF was that infrastructure projects of this scale carry broader social responsibilities.

For many communities surrounding Heathrow the discussion is no longer solely about aviation policy. It is increasingly focused on whether economic growth can support improved living standards, stronger employment outcomes, housing delivery and long term community resilience.

Should proposals for a third runway progress in future years the expectation from many stakeholders appears to be that benefits must extend across borough boundaries ensuring communities in Slough, Hillingdon and Hounslow all play a role in, and benefit from, the future prosperity connected to Heathrow.
