Brands Hill*

The western end of the new runway will be located to the east of Brands Hill. This means we need to divert some roads and rivers and make changes to public spaces in the area. There is also an opportunity to enhance the public open spaces of the Colne Valley around the village.

*This page contains one (1) question located within the “Have your say” section at the bottom of the page.

What happens in Brands Hill

Part of the area to the north of the new runway, west of the M25, will become a rail facility to replace and improve areas that will be lost. This may include a replacement waste incinerator for the facility that will be lost in this area.

The Colnbrook By-Pass will be diverted in two directions. The A4 Bath Road will be re-routed round the north of the runway and the A3044 will move to the west of the M25. We also need to put the M25 into a tunnel, move it closer to Poyle and improve the junctions with the airport and the M4. We need to divert the Colne Brook River.

We are in the process of assessing the impact of noise on the local community facilities, including schools, which may increase once the runway is open. Depending on our findings we may need to improve the noise insulation of these buildings.

Things we’ve changed after listening to you

  • We are proposing improvements to the “green space” around Brands Hill and Colnbrook
  • The Green Loop responds to requests for better walking and cycling routes
  • We have corrected the boundary of our Wider Property Offer Zone to include Sovereign Heights.

Our property policies

To construct and operate an expanded Heathrow we will need to acquire areas of land which currently include residential, commercial and agricultural properties.

MAP | This map shows the areas within our property compensation zones. For assistance, please contact our community relations team using the contact details on this website.

Compulsory Purchase Zone

This area will need to be acquired for the expansion of Heathrow and is referred to as the Compulsory Purchase Zone. Properties in Longford, Harmondsworth (excluding Zealand Avenue and Pinglestone Close), Sipson and Elbow Meadow in Poyle will be required in 2022. It is anticipated that Zealand Avenue and Pinglestone Close would be required in 2026 but these will be affected by construction from 2022.

Heathrow has developed a discretionary enhanced compensation offer where we will buy eligible properties for the open market value plus a home loss payment of 25%. For homeowners, this will be available via the Home Purchase Bond Scheme.

Our Property Policies Information Paper provides details of our compensation offers and eligibility for the schemes.

Wider Property Offer Zone

The above offer also applies for eligible residential properties in the Wider Property Offer Zone.

Both zones referred to above are shown on the map above.

How we will help

We recognise this could be a difficult time for home owners. Our plan is to provide support through our Home Relocation Support Service, where home owners require additional assistance to move home.

It is our intention to protect the most vulnerable owners. We have introduced an interim Property Hardship Scheme that assists those who have a compelling need to move but who are unable to sell their house on the open market, by selling their property to Heathrow.

Commercial and other property policies

Our interim property policies also include the support that is available for commercial and agricultural land and property owners.

Beyond the Compulsory Purchase Zone

Beyond the Compulsory Purchase Zone there are other areas of land which may be needed for associated infrastructure, environmental mitigation and other uses to facilitate the project. The draft Development Consent Order Limits are the extent of land beyond the Compulsory Purchase Zone where we may need to exercise DCO powers for the construction or operation of the project. There are no residential properties beyond the Compulsory Purchase Zone anticipated to be required for acquisition for the project.

Further information is available in the Property Policies Information Paper.

Green space around the village

As well as investment within the village, we are also proposing major improvements to the landscape and environment around it.

Improvements to the landscape will enhance the public open space at Brands Hill and improve access to the countryside.

The re-diverted Colnbrook By-Pass will be raised with planted grass bunds to the sides to help visually integrate the airport and roads into the landscape.

The Green Loop continues into Brands Hill to the north of the railhead and will connect the village to Colnbrook, Stanwell Moor and Harmondsworth. The Green Loop will follow the alignment of the river corridor and will improve access and connectivity to the Colne Valley Regional Park.

Masterplan

Expanding Heathrow is more than building a new runway – we also need to build facilities for passengers, make changes to roads and car parks, and relocate some of the existing airport infrastructure.

Over the past two years we have engaged with and considered the views of over 1,000 stakeholders and our local community to help develop our preferred scheme. Over time, our new runway will increase our flights from 480,000 to just over 750,000 per year. About 80 million people fly with us each year today. This will increase to about 142 million. We will also double the amount of cargo we can handle.

As part of our application to expand Heathrow, we propose that some of the extra flights, which could be up to 25,000 additional flights per year, are introduced early on our existing two runways prior to our proposed third runway being brought into operation.

The map below shows the key features of the new airport when we have finished building. On Local overview – How we will build it we show the steps we will take to get there.

We want to finish the runway as soon as possible. If we get permission, we are aiming to complete it by the end of 2026. When the runway is open we will have finished most of the work closest to communities. Most work after that will be inside the new airport boundary. The main works outside the new airport boundary will be to Stanwell Moor Junction, the southern parkway, and the northern parkway.

Changes to roads and traffic

Changes to roads

To make space for the runway we will need to divert the Colnbrook By-Pass in two directions. We are doing lots of analysis to plan new or diverted routes and minimise disruption in the local area.

A new A4 will go from Colnbrook round the north of the new runway, over the M25, past Saxon Way and to the north of Harmondsworth. It will then head round Sipson and across the M4 spur where it meets the new parkway. It is then routed to the south to re-join its old route to the east of the M4 spur.

Our proposals allow for it to be a dual carriageway, but we currently believe a single carriageway will be sufficient. We will do further analysis before we decide this.

The A3044 also needs to be moved from the western edge of the airport to the west of the M25. It will pass between the new runway and the north of Colnbrook and Poyle. It will then head south between Poyle and the M25 and connect in to Junction 14 of the M25. The roundabout then provides access to Stanwell Moor and the southern part of the airport. There will be a cycle path along the rerouted A3044.

The M25 itself needs to move west and will also be put in a tunnel.

Changes to traffic

While we do not expect the expanded airport to attract more traffic, there may still be localised increases and decreases. While the airport is being built there will also be construction traffic on some roads connecting the airport to the strategic road network.

The maps below. give a preliminary indication of the possible changes to traffic levels in 2022 (during the construction phase), and in 2035 (nine years after we expect the runway to open). These forecasts will be reviewed and updated before we formally apply for consent to expand the airport.

Your responses to this consultation will help us to understand how these potential changes would affect you. There are a range of measures we could use to address any specific concerns. These range from improved signage or changes to junction layouts to measures to promote the use of public transport and encourage the more efficient use of cars.

Changes to traffic - 2022
Construction traffic supporting the expansion of Heathrow is expected to be highest in late 2022/early 2023, just prior to the expected opening of the proposed construction rail link. Traffic on the A4 (Colnbrook By-pass) would be expected to increase in 2022, as this is being considered as one of the main access routes for the construction site. We do not expect any substantial increases in traffic on other local roads through and around Brands Hill as a result of expansion in 2022.
Changes to traffic - 2035
Results of preliminary transport modelling indicate that in 2035, once the expanded airport is fully operational, daily traffic levels could be higher on London Road between Brands Hill and Colnbrook as a result of expansion. Traffic flows would be lower on London Road between Sutton Lane and the M4 Junction 5, because of proposed changes to the road network – in particular the proposed diversion of the A3044, which would change how people travel berween Poyle and the A4.

Air quality – Brands Hill

The expanded airport will be designed to reduce emissions and our plans include ways to manage:

  • The way that people travel to the airport by
  • increasing the use of public transport.
  • The use of cleaner, more sustainable vehicles.
  • Emissions from older, more polluting cars by introducing a Heathrow Ultra Low Emission Zone to charge these vehicles to access the airport.

During construction, air quality in Brands Hill may be affected by construction vehicle emissions.

There may also be odours (smells) when historic landfill sites are dug up. This will be managed by covering to stop odours being given off.

There will be increases in pollutant levels associated with expanding the airport, but these are not considered to be significant. Levels of all pollutants will be within the levels set by the Government to protect health.

The smell of aviation fuel may be noticeable at locations closest to the airport during certain weather conditions.

For more detail on air quality, please see Local overview – Air quality.

Noise in Brands Hill

A larger Heathrow will mean some local communities will hear more noise from construction activities, from aircraft on the ground and in the air, and from local roads.

We will implement a range of measures to reduce the effects on the local community.

Construction noise

No noise effects from construction activities are likely to be experienced in Brands Hill.

Aircraft noise

Noise effects from aircraft are likely to be experienced over the majority of Brands Hill.

Brands Hill does currently experience flights close by from departures and arrivals using the existing northern runway. The existing northern runway is the main runway used for arrivals during easterly operations due to the legacy of the “Cranford Agreement”.

Before the new runway opens, we are planning to introduce runway alternation on easterly operations so arrivals will also land on the southern runway.

The new runway will mean an increase in noise from aircraft landing and taking off directly over the communities of Brands Hill.

To reduce noise, we are proposing to build noise barriers around the airport.

Road noise

Noise from roads near to Brands Hill is not expected to increase with expansion.

Reducing noise effects

We have a number of proposals and plans in place to reduce these noise effects, which are described within Local overview – Reducing noise effects.

We have not identified any community buildings in Brands Hill that are likely to need noise insulation.

Further information

For further information on how we have assessed noise see the PEIR, Volume 1, Chapter 17: Noise and Vibration, Section 17.11. For more information on our proposals, please see section 5 of the Airport Expansion Consultation Document and the Future Runway Operations document.

Runway use to control noise

How we run our three-runway airport in the future will be key to controlling aircraft noise in local communities. Alternating runways will provide respite from aircraft noise.

Choosing which runway is being used for take off and landing and when aircraft arrive and depart during the night are the main ways we can control noise.

Runway alternation

We are proposing that we change how we use the runways at either 2pm or 3pm everyday.

The runway alternation patterns will repeat every four days (so day five will have the same pattern as day one). See the image in the section below.

Night flights

We propose to introduce a ban on scheduled night flights of 6.5 hours between 11pm and 5:30am.

Our proposals ensure that, in normal operations, Brands Hill can expect at least 7 hours when aircraft will not be flying overhead between 10pm and 7am every night.

Also, if you are overflown in the late evening (after 11pm) you will not be overflown in the morning (before 6am).

What will this be like in Brands Hill?

The illustration below shows what this would mean in the future, compared to today, for daytime and night-time respite in Brands Hill over a 4 day period. The green colours show periods of respite, and the orange colours show periods of direct overflight.

Whether Brands Hill gets noise from aircraft overhead will depend on the direction of the aircraft (heading east or west) and which “mode” the runway is being used in. The modes are landings only, departures only or “mixed-mode” (both landings and departures).

For example, when planes are taking off to the west, Brands Hill will not get noise overhead when the new runway is being used for landings, but will get noise overhead when it is being used for departures or in mixed mode.

When planes are taking off to the east, Brands Hill will not get noise overhead when the new runway is being used for departures, but will get noise when it is being used for landings or in mixed mode.

When there is no noise overhead, there will still be noise from planes on the ground or from planes using the existing runways. Brands Hill will hear noise from aircraft engines as they move from the terminals to the runway for departure.

For more information on our proposals please see Future Operations and the Future Runway Operations document.
