Details
There is currently restricted access to navigation at Teddington Lock, which is normally open 24 hours.
As works to repair Teddington Launch Lock progress, the Environment Agency will continue to manage navigation through Teddington Barge Lock. The Agency has established working practices which allow for operation of the barge lock. This will require two people to operate safely.
Divers will be attending Teddington Launch Lock between Wednesday 1 October and Friday 31 October. Navigation through Teddington Barge Lock during this period will be operated at specific times.
Weekdays (Monday to Friday)
During weekdays, Teddington Lock will be closed for navigation outside of the stated times below.

Weekends (Saturday and Sunday)
Passage through the barge lock will be available on weekends (Saturday and Sunday) during October from 9am to 5pm. Please be aware the last lock movement will be 30 minutes before closure.
Due to the revised process, passage through Teddington Lock may take longer than usual.
For significant pre-organised events and clubs requiring passage outside of the stated operational hours, requests for passage can be made 10 working days in advance by contacting WaterwaysThames@environment-agency.gov.uk.
The Environment Agency will try to accommodate these requests where possible, but this cannot be guaranteed.
Teddington Lock will be closed to navigation for essential maintenance works for published periods from 5 November to 3 December 2025 as part of the Environment Agency’s planned Capital Investment Programme. We will provide further information regarding anticipated closure dates as soon as possible.
We apologise for any inconvenience that this notice causes and thank you for your patience during this time. We will update this notice with more information as soon as possible.
