What we are doing
From 25 October 2021, we will start excavation works to prepare the base of the railway tunnels in the area shown on the map . We will be excavating the earth to prepare the area for the launch of the Tunnel Boring Machines and the creation of the portal area.  The earth excavated from this area will be stored temporarily at the golf course driving range. This stockpiled earth will then be used to landscape the area around the tunnels and the tunnel entrances once the construction works have been completed.

Excavation of area and placement on temporary storage area
• These works will take place in two shifts. This activity is needed to prepare the area for the concrete pours before the cold weather.

Continuous cement pour
• Two periods of fifty hours continuous pour of concrete is required to build two base slabs for the portal structure. The pour has to be continuous so that there is no loss to the structural integrity of the building.

Work mitigation

We will:
• Continue to monitor sound levels both inside and outside our site compound
• Carry out attended monitoring for the first two weeks to ensure noise and vibration levels are within our required limits
• Steel fixing works will only be done at the very bottom of the excavation at 11 meters below ground level
• Where possible, acoustic covers and blankets will be used
• Cutting and welding will only be carried out during the day (8am to 6pm)
• Dust mist cannons will surround the working areas
• Lighting will face away from residential properties.

We would like to apologise in advance for any disruption or inconvenience this may cause. Every effort is being taken to ensure that these works are carried out in the least impactful way. We will ensure that disruption is kept to a minimum.

Our engagement team will be available to discuss these works with the local community in the following ways:

– A presentation will be available on the HS2 in Hillingdon website page
– Staff will be available at The Greenway near the U81 footpath on the 19th of October between 4pm and 6pm, and 21st of October between 1pm and 3pm

2  Update: Notice of lane closure at Harvil Road

What we are doing

We wrote to you in August to advise you that we would be carrying out utility connections until 30 September 2021. However, we will need additional time to complete these works which will be extended until the end of October 2021.

We will be carrying out utility surveys and utility connections along Harvil Road as part of the road realignment works. Temporary traffic management and lane closures will be required to ensure these works can be carried out safely.

We will work during off peak hours where possible to minimise disruption.

HS2/Thames Water – High Road

HS2 Works Notification: Thames Water works in Hillingdon

We’re writing to let you know about some planned works that we will be carrying out in your area. 
From Monday 27 September, we will be carrying out trial holes off High Road – opposite the unused road next to the entrance of The Soldiers Return. Our work will take up to six days to complete.

The footpath will remain open for the duration of our works.

The road will remain open at all times, but we will need to close half of the northern lane. There will be traffic management in place to keep the traffic flowing.

Sewer Survey
We will be carrying out a CCTV survey of our survey on the private road of The Green on Tuesday 28 September. Our survey area is expected to cover the public green area opposite the houses.

Enabling work
We plan to start enabling works on Monday 4 October, subject to planning permission being granted by London Borough of Hillingdon with no planning conditions that would restrict such work commencing at that time

Textile (+) recycling change

From LBH:

From Monday 20 September, Hillingdon Council’s textile collection service will change to TRAID – making it easier and quicker to for all residents to recycle unwanted clothes, shoes and accessories.  Instead of kerbside collections, the charity TRAID will run free home collections – and they’ll also take small electrical items such as hairdryers, toasters or mobile phone chargers alongside textiles.

This enhanced service is open to all residents, including for the first time residents living in flats who were previously unable to use the council’s kerbside textile collection service. All residents need to do is book a collection at a day and time that suits them, bag textile donations in a minimum of one large bag or three small carrier bags and then let TRAID handle the rest. They will arrive in a branded van and knock on the door – they will only accept clothes, shoes and accessories (i.e scarves, jewellery and gloves). They will not accept duvets or pillows.

The improved service means that clothes in a good condition can be given a new lease of life once they are sold in TRAID stores. Cllr Eddie Lavery, Hillingdon Council’s Cabinet Member for Environment, Housing and Regeneration said: “We’ve teamed up with TRAID to make textile recycling that extra bit easier for our residents. This new partnership brings many benefits, allowing thousands of residents in flats to recycle their textiles from home for the first time, and also being able to donate small electrical items. “So, if you’re having a wardrobe clear out or simply have some items you no longer need but are in good condition – from September, use TRAID. It’s quick and easy to use and every item donated helps to make a difference both to the environment and to people’s lives.”

Book a free collection at a day and time that suits you either online at, by calling 020 8733 2580 or emailing When it launches, residents will no longer need to request purple recycling bags from the council but if they have some leftover they can still be used for this purpose.

All profits from TRAID help fund international development projects to improve conditions and working practices in the textile industry. The scheme also helps educate people of all ages about the impacts of textiles on the environment and people’s lives, and how we can make more sustainable choices.

There are also many textile banks across the borough, which you can also use. Details on where they are located can be found on the council’s website.
