Teddington Launch Lock repairs

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

We’re pleased to confirm that our construction partner, Bam Nuttal, mobilised to site on Monday, 15 September 2025 to begin the refurbishment works at Teddington Launch Lock.

The project team have installed site compounds and welfare facilities at Ham Street Car Park and Teddington Lock.

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. These minor diversions are due to commence over the next few weeks.  At all other times, the Thames Path remains open as usual, and diversions will not impact Teddington Footbridge.

Use of the Teddington Barge Lock will continue throughout construction to maintain navigation.

Current Progress

Floating barges and pontoons have been moved to the Launch Lock so that a mobile crane can begin lifting out the upstream lock gates. This work is planned for week commencing 10 November 2025. 

Next Steps

Once the upstream lock gates are safely stored away from the lock, our contractor will begin removing the damaged sections of the lock chamber so that it can be repaired. 

We anticipate the project will be on site for approximately one year, with ongoing construction work throughout this period. 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.
