Kidbrooke site mobilisation works

Since the end of  May 2022, site mobilisation works have started at our Kidbrooke site, from 8 am – 6 pm, Monday – Friday.

The first phase of works involves setting up containers for offices and a car park, followed by shaft sinking, which is scheduled to be complete by the end of the first quarter of 2023. There may be a small increase in HGVs from June within working hours but we will monitor our activity to ensure we can minimise noise.

We expect there to be some parking suspensions around August and will confirm which roads are due to be affected closer to the time.

Our site in Kidbrooke is located at the end of Nelson Mandela Road in the Royal Borough of Greenwich (between the National Maritime Museum Collections Centre and the Birdbrook Nature Reserve).

We are building a permanent tunnel shaft and headhouse building to provide ventilation and access to the cable tunnel once it has been built. Planning consent for the headhouse building was granted in February 2019 by the Royal Borough of Greenwich.



  • We are due to occupy the site in spring 2022 and begin digging the shaft in summer 2022.
  • Headhouse construction is scheduled to begin in late 2022.

We anticipate that there will be a low volume of HGV movements – approximately 8 HGV movements per day during shaft construction, and 4 per week during headhouse construction.

Working hours

Site working hours will be 7am to 5pm Monday to Friday, and 8am to 1pm on Saturdays. No work on Sundays or Bank Holidays is expected.


The shaft will be approximately 10.5m in diameter and up to 19m in depth. The headhouse will have a footprint of 8.5m by 4.7m by 5m in height.
