Teddington Launch Lock repairs

Teddington Lauch Lock Reconstruction

The Environment Agency is carrying out improvement works to refurbish Teddington Launch Lock that will result in a reliable, operational lock.

In September 2025, our construction partner, Bam Nuttal, mobilised to site to begin the refurbishment works. To date, the team has completed ground investigations, removed the upstream lock gates, and installed the upstream stop logs / propping throughout the lock chamber to support the lock during construction.

Following the Christmas break, the site team have removed the downstream lock gates and have installed a temporary stop log barrier in their place. They will now begin to dewater the lock chamber to allow engineers access to the lock chamber to continue the works. Both sets of lock gates have been removed from site for inspection and repairs.

Please note, the Thames path at Teddington Lock and Ham Street car park will be diverted for short periods of time throughout the works and will be clearly marked on site.

Teddington Barge Lock will continue to be the primary lock for our Navigation customers throughout Launch Lock’s re-construction. Once the Launch Lock is returned to operational service, it will become the primary lock for Navigation.

We anticipate the project will be on site for approximately one year, with the lock likely to reopen in late Summer 2026. The project will deliver improvements that enhance the safety, functionality, and resilience of Teddington Lock.

We are working closely with Richmond and Wandsworth Councils to give advanced warning of any diversions and to limit the inconvenience to our customers.
