SOE10686 – Coldharbour Lane, Hilldenborough (Coldharbour Lane)
PROJECT: SOE10686
Location: Coldharbour Lane, Hilldenborough
(Coldharbour Lane)
Update: 31.10.2025
Last week, we planned to complete the open-cut section, install the new booster main, and fully reinstate the road. This would have allowed us to remove the current road closure at the junction of Tonbridge Road and move to restricted access hours (09:00–12:00 and 12:30–16:00, Monday to Friday), as detailed in the letters issued to residents of Coldharbour Lane, Derby Close and Hardwick.
However, during our final connection phase to commission the new main, we identified a leak at the governor supplying gas to the whole of Coldharbour Lane. This issue must be resolved before we can safely progress.
Updated Traffic Management
Due to this essential repair, the closure at the junction of Tonbridge Road will need to remain in place until 17.11.2025.
Residents will continue to use Knowsley Way to access Coldharbour Lane for the next two weeks while we carry out the necessary works.
The previously communicated restricted-access schedule will be postponed by two weeks, and an updated letter will be delivered to affected properties.
To support safe access for larger vehicles using Knowsley Way, no-parking notices, cones, and signage will be issued to residents on this road.
Resident Communications
We are actively updating residents through letters, and this page will now be updated every 2–3 days. Please check back regularly for further information.
Thank You
We sincerely apologise for the disruption this project has caused and greatly appreciate the continued patience and cooperation of all residents as we work to complete this essential upgrade to the gas network.
Update: 08.10.2025
As of 30th September Coldharbour Lane has been closed at the junction of Tonbridge Road, this is for the open cut works which will take place for the next 3 weeks.
Once this is complete and reinstated we will continue to work up into Coldharbour lane however, inserting the mian inside the old metallic instead of open cutting.
This will mean access will be restricted from approx. 9am-3pm Monday to Friday to allow work to take place, reisdnets will be urged to either get out of the road before this period as access wil be minimal.
Our lights on Tonbridge Road, will be removed on 08/10 as this is providing traffic difficulties in the area.
We understand that the works on Coldharbour Lane have caused disruption, and we appreciate residents’ patience. The existing gas main has reached the end of its serviceable life and must be replaced to ensure safety and reliability.
Due to the location of the gas main, a road closure will be required to safely carry out the replacement works. This will be a rolling road closure, moving along the road as our team progresses each week. We are aware that Coldharbour Lane is a dead-end road. To minimise disruption, the road will be opened outside of our working hours. Our working hours are 9:00am to 4:00pm, Monday to Friday. There will be a 30-minute interval every day from 12:00pm to 12:30pm where the road will be opened to allow an extra period for deliveries and access.
We have carefully planned our working hours to allow access and deliveries before 9:00am, and again after 4:00pm, with a 30-minute interval from 12:00pm to 12:30pm.
During these hours:
Vehicle access through the work area will be restricted, with passage allowed only for emergency services.
Residents are asked to plan their travel in advance and move vehicles from the affected area before work begins each day.
Pedestrian access will be maintained.
Access and parking restrictions will affect some properties initially but will reduce as the works progress. Parking suspensions on Knowsley Way and Mount Pleasant will be lifted once we move to later phases. Emergency access will be maintained at all times.
The section with restricted access is scheduled to begin the week commencing 3 November 2025. We are working closely with local businesses and the hospital to minimise disruption.
The project is expected to take approximately eight weeks, with impacts gradually decreasing as the works move along the road.
We will regularly update this page so that everyone is aware of the closure location and what sections we are looking to work on.
Our first phase will be below
