Stanley Hill, Amersham


Start date: 24 July 2023

Duration: 6 weeks

Project manager: William Sadler

Local delivery partner: Stanmore Quality Surfacing Ltd


Project overview

We are upgrading the gas pipes along Stanley Hill to ensure you continue to receive a reliable gas supply for many more years to come. Our aim is to replace all the metallic mains and service pipes in these locations. This means that we will need to excavate holes in the ground to access the gas pipes in order to inspect and replace them.

Due to the nature of the work involved, we have planned to deliver it in two phases to maximise efficiency and minimise disruption.

Phase 1 – 24 July 2023

This phase will be completed under a road closure with multi-way lights at the junction of White Lion Road. A full road closure is necessary due to the location of the existing gas pipe which is beneath the white line in the middle of the road.

A temporary pedestrian crossing be in place outside of St George’s C of E Infant and Preschool.

Phase 2 – 31 July 2023

The second phase will be completed under a road closure from Stanley Hill Avenue to corner of Stanley Hill.

Phase 3 – 14 August 2023

The final phase will be completed under multi-way traffic lights.

Throughout the project access to driveways will be maintained where possible. Where this is not possible, we have agreed with Amersham that residents can use their car park during this time.

Please note that parking will be available on a first come first served basis and any vehicles and their contents are left entirely at the owners risk.

Project updates

18 August - 09:30

We are pleased to confirm that all of our engineering and reinstatement work is now complete. The temporary traffic lights will be removed from site by the end of the day today.

The road closure will remain in place over the weekend ready to handover the site to Buckinghamshire Council's  re-surfacing team on Monday 21 August.

Thank you for your patience and understanding during our work.


11 August - 09:40

This week the entire section of phase 3 has been excavated ready for the new pipe to be inserted today. Once done, this will then complete our engineering works.

Re-surfacing work will be undertaken by Buckinghamshire Council will begin on 17 August, this work will be completed within the current road closure.


04 AUGUST- 11.00

Phase 2 of the project is now complete. This week the team replaced 140m of existing gas pipe, this included twenty- two of the service pipes that feed gas into properties within this section. Please be advised, during the weekend the team will be clearing up and preparing for the reinstatement stage.

Next week, phase 3 of the project will begin. To minimise the traffic as we move into phase 3 of the project, we have agreed with Buckinghamshire Council to keep the road closure in place whilst we work past Stanley Hill Avenue with temporary traffic lights. The traffic light heads will be positioned on Stanley Hill Avenue, Stanley Hill and Salisbury Close.

To safely manage this section, we would kindly ask all residents to enter/exit from the White Lion Road roundabout end from Monday 7th August as we will need to permanently close the section before the traffic lights.

Buckinghamshire council will be starting the re-surfacing once we have competed our works starting from the White Lion Road roundabout working down Stanley Hill.

This week the team has replaced the first 100m of the existing gas pipe, this included seven of the service pipes that feed gas into properties within this section. The final two service pipes within phase 1 will be replaced on Monday and Tuesday next week. Once they are complete the temporary traffic lights will be taken down, we hope this will be on Wednesday.

The teams will continue work over the weekend, this will include reinstatement of the area.

Preparatory work for phase 2 of work will begin on Monday.


21 July - 12:00

The project will begin on Monday morning as planned. You will see the team on site at 9am to set up the road closure. Following this, three-way lights being installed at the White Lion Road roundabout

Once to site is set-up, the team will begin excavating holes to access the pipes that feed gas into properties within the first phase of work.

Towards the end of the week, the team hope to ready to replace the first section of the existing gas pipe, along with the smaller pipes that feed gas into properties.
