Heathrow’s Third Runway: What It Means for Residents Facing Compulsory Purchase

After years of delays and legal challenges, the expansion of Heathrow Airport, including the construction of a third runway — is firmly back on the government’s agenda. While the project promises economic growth and increased capacity, it brings serious disruption to local communities, particularly for those whose homes are subject to Compulsory Purchase Orders (CPOs).

As a Chartered Surveyor and RICS Registered Valuer, I act for homeowners, leaseholders, and businesses affected by CPOs, helping them secure fair compensation and navigate the complexities of relocation or loss of property. Here's what you need to know.

Who Is Affected by the Heathrow CPO?

To accommodate the new runway and related infrastructure (including rerouting the M25), hundreds of homes are expected to be demolished. Areas such as Longford, Harmondsworth, and parts of Sipson are already earmarked for potential clearance. If your property lies within or near the safeguarded area, you may eventually receive a Blight Notice or be included in a formal CPO process.

What’s the Timeline?

While the exact timetable is subject to government and planning approvals, here’s the likely sequence:

· 2025–2026: Revised DCO (Development Consent Order) application submitted by Heathrow

· 2026–2027: Public consultation and examination

· 2027–2028: CPOs confirmed by Secretary of State (with opportunity for objections and representations)

· 2028–2030: Compulsory purchases and site clearance commence

· 2030–2035: Construction of third runway and associated development

Early engagement is key. Property owners may be able to serve a Blight Notice before the CPO is confirmed, if their property is unsellable due to the safeguarding designation.

What Compensation Are You Entitled To?

If your home is subject to a confirmed CPO, you may be entitled to:

· Market value of the property

· Disturbance compensation (moving costs, legal/surveyor fees, temporary accommodation)

· Home Loss Payment (typically 10% of market value, capped)

· Statutory interest on late payments

· Professional fees covered – including your surveyor and solicitor

If you serve a Blight Notice, and it's accepted, the acquiring authority (Heathrow) must purchase your property on CPO terms even before the CPO is formally confirmed.

How Olden Property Can Help

As a specialist in compulsory purchase and property valuation, I offer:

• Independent Market Valuations – to establish the correct compensation

• Blight Notice advice – whether and when to serve one

• Negotiation Support – I act on your behalf in discussions with Heathrow’s acquiring team

• Compensation Claims – including disturbance and home loss

• Strategic Advice – should you sell early, wait, or serve notice?

  I work entirely independently, with your interests at the forefront.

Experience You Can Trust

I’ve acted for homeowners and leaseholders affected by:

· HS2 compulsory purchase schemes

· Council-led regeneration

· Utility and road schemes

· Airport safeguarding projects

I understand both the technical valuation side and the emotional strain of losing your home. My job is to ensure you’re treated fairly, compensated fully, and supported throughout.

What Should You Do Now?

If you live near Heathrow and suspect your home could be affected:

1. Check if your area is within the safeguarding zone

2. Start assembling documents – title deeds, historic valuations, mortgage statements

3. Seek early advice – understanding your position now will make any future claim easier

4. Keep records – of communications, consultations, and any impacts on your ability to sell
