Update: vegetation clearance at Mandeville Road site, Northolt

What we are doing

Safe stop down to SCS works from 10 October 

Safety is our number one priority at HS2. Following an incident that occurred at the Green Park Way site in Ealing, works are being safely halted across the London Tunnels section of the route, including sites in Ealing. While no workers were physically harmed, our contractor, Skanska Costain STRABAG joint venture, is undertaking a comprehensive review of safety procedures and leadership on their sites before a safe restart can take place. 

Works will be brought to a safe stop and will remain on hold until we’re satisfied that all appropriate measures are in place to protect the workforce. We anticipate the review may take a number of weeks depending on the area and the type of work involved. 

We will provide details on when the safe stop will be in place over the course of the next week.

We wrote to you in September about work on the 22 and 23 September 2025 to trim and clear low-level vegetation in the railway embankment near the Mandeville Road Vent Shaft site. The work has been postponed and will now take place on Monday 13 and Tuesday 14 October.

We’ll use handheld tools to carry out these works. You may hear some noise. We apologise for any disruption this work may cause.
