Affected by Heathrow’s Third Runway proposals?
Take control of what happens next.
Heathrow’s expansion proposals could affect property, land, businesses, livelihoods and long-term investment decisions.
Even if your property is not within the proposed runway footprint, it may still be affected by new roads, rail infrastructure, utilities, construction works, access arrangements or rights over land.
Understanding your position early can help you protect your rights, preserve evidence and make informed decisions before proposals become more advanced.
Clear advice when the future of your property or business is uncertain
At Newsteer, we believe people and businesses affected by compulsory purchase deserve clarity, fairness and confidence at every stage.
Our dedicated team of compulsory purchase specialists advise owners, occupiers, landlords and businesses that may be affected by Heathrow’s Third Runway proposals.
We have experience advising both parties affected by compulsory purchase and organisations promoting schemes that rely on compulsory purchase powers. That helps us anticipate how an acquiring authority may approach land, valuation and compensation issues, while remaining firmly focused on protecting your position.
Fair outcomes often depend on obtaining the right representation at the right time. Strong advice can help turn an uncertain compulsory purchase process into a managed commercial outcome.
How Newsteer can help
Every affected property and business will have a different combination of ownership, occupation, valuation and commercial issues.
Newsteer can help you:
- understand the likely effect of the proposals;
- review plans and property information;
identify rights and potential compensation entitlements; - assess statutory blight and early acquisition options;
- prepare valuation and compensation evidence;
- record and evidence business impacts;
- develop relocation or mitigation strategies;
- respond to consultation and compulsory acquisition proposals;
- negotiate with HAL and its advisers; and
coordinate property, valuation, planning and commercial advice.
Our aim is to give you a clear strategy, not simply explain the process.
Why it is important to act now
Heathrow’s Third Runway has faced significant challenges and delays. Although implementation may still appear some way off, Heathrow Airport Limited (HAL) is now progressing its work.
HAL has appointed compulsory purchase specialists, who have already started to contact owners and occupiers.
Waiting for a formal notice may mean losing valuable time to:
- understand how the emerging proposals affect you;
- preserve evidence of business and financial losses;
- review property, ownership and lease information;
- consider relocation or investment decisions;
- understand possible compensation entitlements;
- respond effectively to consultation;
- assess whether statutory blight or a discretionary property scheme may apply; and
- prepare a clear negotiating strategy.
Early action does not mean committing to a particular course. It gives you the evidence and options needed to make better decisions as the scheme develops.
More than a property issue
Compulsory purchase can affect far more than the value of land or buildings.
For a commercial occupier, landlord or business owner, uncertainty around Heathrow expansion could influence:
- investment and financing decisions;
- lease negotiations and renewals;
- business planning;
- customer retention;
- staff recruitment and travel;
- operational continuity;
- relocation requirements;
- supply chains;
- redevelopment plans; and
- the long-term value or marketability of an asset.
A property may also be affected before any formal acquisition takes place. Customers, neighbouring businesses or occupiers may begin to move from an area, potentially creating early trading impacts.
These issues need to be considered together. Newsteer brings compulsory purchase, valuation, property, planning and commercial expertise around your circumstances, helping you understand not only what may be claimable, but how the proposals could affect your wider plans.
Heathrow Third Runway compulsory purchase FAQs
1. What is the current Heathrow Third Runway proposal?
The principal expansion proposal remains Heathrow Airport Limited’s Northwest Runway scheme. This involves constructing a new runway to the north-west of the existing airport.
Alternative designs have also been promoted, including the Arora “Heathrow West” proposal, which is intended to require less land.
The HAL proposal has government backing, and HAL is working towards promoting the scheme through a Development Consent Order, or DCO.
The design, land requirements and timetable may continue to evolve as the proposal progresses.
2. How do I know if my property is affected?
A property may be affected if it:
- falls within the proposed Compulsory Purchase Zone, or CPZ;
- is required for the runway, roads, rail infrastructure or utilities;
- is needed temporarily during construction;
- is affected by new access arrangements; or
- is subject to proposed new rights over land.
Heathrow has identified properties within its anticipated CPZ and has contacted many owners and occupiers directly. However, a property does not necessarily need to be within the proposed CPZ to experience wider physical, operational or commercial effects.
3. Can I be affected even if my property is outside the runway footprint?
Yes.
Infrastructure associated with the expansion may affect land situated outside the runway area. This could include:
- new or altered roads;
- rail infrastructure;
- utility diversions;
- drainage works;
- construction compounds;
- temporary access;
- environmental mitigation; and
- new rights over land.
In some cases, only part of a property may be required. In others, HAL may seek rights to access or use land without acquiring the whole property. Understanding precisely what is proposed is essential before assessing the potential effect on value, occupation or business operations.
4. What is compulsory purchase?
Compulsory purchase is a statutory process through which land or rights over land can be acquired without the owner’s agreement.
The powers must be authorised for an eligible project and approved through the relevant legal process. For the Heathrow expansion proposals, compulsory acquisition powers are expected to be sought through a DCO.
Where land or rights are compulsorily acquired, compensation is payable in accordance with the applicable legislation and established legal principles.
Compensation can be complex. The outcome will depend on the interest held, the effect of the scheme and the particular circumstances of the owner or occupier.
5. Will Heathrow definitely acquire my property?
Not necessarily.
Depending on the final design and land requirements, a property could be subject to:
- full acquisition;
- partial acquisition;
- temporary possession;
- acquisition of rights only;
- changes to access;
- construction-related effects; or
- no acquisition if the scheme or design changes.
The position may become clearer as HAL develops and consults on its proposals. Advice at an early stage can help you understand the range of possible outcomes and avoid making decisions based on assumptions.
6. What if I need to sell before compulsory purchase powers are confirmed?
In some circumstances, an owner may have rights under statutory blight legislation or may qualify for one of Heathrow’s discretionary property schemes.
Where the relevant qualifying criteria are satisfied, an owner may be able to require the acquisition of a property before formal compulsory purchase takes place. The statutory basis is generally the property’s unaffected market value, together with any other payments for which the claimant qualifies.
Eligibility is not automatic. It depends on factors including:
- the property interest held;
- the nature of occupation;
- the property’s relationship to the proposed scheme;
- the relevant statutory provisions; and
- the evidence that the property has become difficult to sell except at a substantially reduced value.
Further information is available through the Government’s Heathrow expansion blight guidance and Heathrow’s property compensation schemes.
7. What is statutory blight?
Statutory blight can arise where a major infrastructure or planning proposal makes an affected property difficult to sell at its unaffected market value.
An eligible owner may be able to serve a blight notice requiring the relevant authority to purchase the property.
If the notice is accepted, the owner may receive the unaffected market value of the property and other compensation payments available under the legislation.
Strict qualifying conditions and procedural requirements apply. Obtaining advice before serving a notice can help clarify whether you qualify and what evidence will be needed.
8. What compensation could I receive if my property is acquired?
The compensation available will depend on your property interest, occupation and individual circumstances.
Potential elements may include:
- the open market value of the property;
- a home loss payment for qualifying residential owners;
- disturbance compensation;
- business relocation costs;
- reasonable professional fees;
- removal costs;
- Stamp Duty Land Tax on an eligible replacement property;
- losses arising from the relocation of a business; and
- other qualifying losses caused by the acquisition or displacement.
The assessment is governed by several pieces of legislation and extensive case law. It is therefore important to identify every potentially relevant head of claim and maintain evidence supporting the losses incurred. A properly prepared claim should reflect the full effect on the claimant, rather than concentrating only on the value of the property being acquired.
9. What if I am a tenant rather than an owner?
Tenants can still have significant rights.
Depending on the lease, the nature of occupation and the circumstances of the acquisition, compensation may be available for:
- the value of a leasehold interest;
- business losses;
- disturbance;
- relocation costs; and
- loss of goodwill.
Entitlement may be influenced by the remaining lease term, security of tenure, contractual provisions and the way the property is occupied. Businesses may also experience effects before any formal acquisition. For example, customers or neighbouring occupiers may relocate as a proposed scheme advances. These early impacts are sometimes described as shadow losses. Whether a particular loss is recoverable will depend on the facts and applicable compensation rules. However, it may be necessary to start recording relevant changes and retaining supporting evidence now.
10. Will Heathrow pay my professional fees?
Reasonable surveyor and solicitor fees incurred in preparing and pursuing a compensation claim are generally recoverable where they are necessarily and properly incurred in connection with the compulsory acquisition.
The precise position will depend on the circumstances and the work undertaken.
It is sensible to discuss the scope and recovery of fees at an early stage, particularly before agreeing instructions or taking significant action.
11. Can I object to compulsory acquisition?
Yes.
HAL is expected to seek compulsory acquisition powers through a DCO. During that process, affected owners, occupiers and businesses will usually have opportunities to:
- respond to consultations;
- submit representations;
- register as interested parties;
- participate in the examination;
- attend or speak at relevant hearings; and
- object to proposed compulsory acquisition powers.
Objections are more effective when they clearly explain the effect of the proposal, identify the land or rights involved and are supported by appropriate property, valuation, operational or technical evidence.
12. What is a Development Consent Order?
A Development Consent Order is the planning and land acquisition mechanism used for Nationally Significant Infrastructure Projects.
A DCO can combine several approvals within one process, including planning consent and powers for the compulsory acquisition of land or rights.
The Heathrow expansion proposals are expected to progress through this process. It will give affected parties opportunities to understand the proposals, make representations and participate in the examination.
The Planning Inspectorate provides a guide to the process for Nationally Significant Infrastructure Projects
13. When should I seek professional advice?
As early as possible.
Early advice can help you:
- understand whether and how your property may be affected;
- protect evidence of losses;
understand your legal and compensation position; - review HAL’s emerging proposals;
prepare for consultation and negotiation;
evaluate property, lease or investment decisions; - plan for potential relocation; and
avoid actions that could prejudice a future claim.
This can be particularly important for businesses, tenants, investors and landlords, where property decisions are closely connected to operational and financial plans. Seeking advice does not commit you to objecting, selling or relocating. It allows you to make those decisions from an informed position.
14. What should affected owners and occupiers do now?
Useful steps include:
Confirm whether your property is within or close to the proposed scheme or safeguarded land.
Keep clear records of ownership and occupation.
Retain leases, licences, deeds and other property documentation.
- Preserve business accounts, budgets and trading information.
- Record relevant changes in turnover, costs, customers or operations.
- Keep copies of correspondence and plans received from HAL or its advisers.
- Monitor consultations and project updates.
- Consider how the proposals could affect investment, lease, relocation or operational decisions.
- Obtain specialist compulsory purchase advice before agreeing terms or making significant commitments.
Good evidence can be critical. Claims are easier to assess and support when records have been maintained from an early stage rather than reconstructed later.
15. What is the likely timetable?
The precise timetable remains dependent on government policy, consultation, scheme development and the DCO consent process.
Significant planning and statutory stages remain before construction could begin, and implementation is expected to be several years away.
However, the distance to construction should not be confused with the time at which property and business impacts begin. Engagement, consultation, land referencing and negotiations can happen much earlier.
Any timetable displayed on this page should be dated and attributed to HAL, with a note making clear that it is subject to change.
16. What is the biggest mistake affected owners and occupiers make?
A common mistake is engaging with acquisition proposals or agreeing terms before fully understanding the legal, valuation and compensation position.
Early decisions can influence later options and claims.
Before entering substantive negotiations, affected parties should understand:
- what land or rights may be required;
- the possible effect on the retained property;
- which compensation provisions may apply;
- the evidence needed to support a claim;
- whether relocation is realistic;
- the potential impact on business operations; and
- the strategic options available.
The objective is not to make the process unnecessarily adversarial. It is to enter discussions with the evidence, advice and commercial understanding needed to achieve a fair outcome.
How the Heathrow DCO process is expected to work
1. Pre-application
HAL develops the scheme, refines its design, identifies potential land requirements and prepares its application. During this stage, affected owners, occupiers, businesses, statutory bodies and local communities may begin to receive information about the proposed works and their likely effects. This is an important opportunity to understand the emerging proposal and raise issues before the application is finalised.
2. Consultation
HAL must undertake formal consultation and publicise the proposed development. Consultation material is likely to include plans and scheme information, environmental information, details of potentially affected land, proposed mitigation and information explaining how people can respond. HAL must consider the responses received and explain how the consultation has influenced its application. Affected parties should make their responses specific, evidence-based and focused on the actual effect of the proposal.
3. Submission of the DCO application
HAL submits its application to the Planning Inspectorate. The application is expected to include the draft Development Consent Order, land and works plans, an environmental statement, a statement of reasons supporting compulsory acquisition, a funding statement, a consultation report and a book of reference identifying interests in affected land. These documents will provide more detail on the land and powers being sought.
4. Acceptance
The Planning Inspectorate considers whether the application is complete and meets the required standard. If the application is accepted, it moves to the pre-examination stage. Acceptance does not mean that consent has been granted. It means the application is considered suitable to proceed to examination.
5. Pre-examination
Owners, occupiers, businesses and other interested parties can register to participate by submitting a relevant representation. Registration is important because it allows affected parties to become involved in the examination and raise concerns relating to land take, compulsory acquisition, access, property impacts, business effects, compensation, mitigation and alternative approaches. Affected parties should monitor the registration deadline carefully.
6. Examination
An Examining Authority considers the application. The examination is primarily a written process, although hearings may also be held. It may consider planning, environmental effects, transport, property and land, business impacts, compulsory acquisition, alternatives and mitigation. The statutory examination period is usually up to six months. Professional evidence may be valuable where an objection or representation involves technical property, valuation, business or compulsory acquisition matters.
7. Recommendation
8. Decision
9. Post-decision and implementation
Following the decision, there may be a period during which a legal challenge can be brought. Once the order is in force, HAL may begin using the powers granted by the DCO, subject to the terms of the order and the relevant statutory procedures. The existence of powers does not remove the need to assess compensation or negotiate claims. Owners and occupiers should continue to maintain records of the effects and costs they experience.
Early advice can protect evidence, clarify your options and put you in a stronger position before negotiations begin.
