Heathrow Third Runway: January 2026 Update – What It Means for Property Owners

In January 2026, further clarity has emerged on the proposed third runway at Heathrow Airport, with confirmation that the UK Government continues to back Heathrow’s expansion proposals in principle. While this does not yet amount to planning permission, it does signal a clear policy direction and renewed momentum behind the scheme.

For property owners and businesses in areas potentially affected by the expansion, this shift is important.

Government Backing – Why It Matters

The Government has confirmed that Heathrow’s own expansion scheme will form the basis of the revised Airports National Policy Statement. In practical terms, this means:

· The project is now being actively progressed rather than paused

· Formal consultation and planning stages are expected to follow

· The risk of land acquisition and compulsory purchase is becoming more tangible

Although construction remains several years away, policy support significantly reduces uncertainty around whether the scheme will proceed at all.

Implications for Homeowners

For homeowners near the proposed runway and associated infrastructure, Government backing can have immediate effects even before any compulsory purchase:

· Blight risk – properties can become harder to sell or mortgage due to perceived future acquisition

· Value uncertainty – buyers often discount prices where long-term infrastructure schemes are proposed

· Early engagement opportunities – in some cases, blight notices or voluntary purchase routes may become relevant

Taking professional advice early allows homeowners to understand their position before decisions are forced upon them.

Implications for Businesses and Landowners

Businesses face a different but equally important set of considerations:

· Potential loss of premises or partial land take

· Disturbance compensation for relocation, fit-out costs and business interruption

· Strategic decisions around lease renewals, investment, or exit timing

For landlords, expansion proposals may also affect rental value, covenant strength and long-term investment performance.
