Using the locks
Lock keepers work at Environment Agency locks to help boaters through the lock during their hours of duty.
To find out whether there will be a lock keeper on duty at the lock you are visiting, check our River Thames lock keeper service page.
When lock keepers are not available you may work the lock yourself, at your own risk. Some locks have power, which makes them easier to operate.
Full details of the service lock keepers offer on the River Thames are in the River Thames customer charter.

Teddington Lock has a 24 hour service all year.
At all other locks, you need to operate the lock yourself when the blue self service signs are displayed.
Operating the lock yourself
Operating instructions are posted at locks. Read the operating instructions before you operate the lock.
If you are operating the lock yourself:
- stay close to the sluice controls while the sluices are in operation
- close the lock gates properly before slowly opening the sluices to fill or empty the lock
- leave the lock empty and shut the gates after use - there is often a public right of way over the gates
In an emergency you should close all sluices before dealing with the situation. Emergency contact details are displayed at each lock.
Camping at lock sites
We are sorry to have to inform you that we have closed all Environment Agency campsites at our River Thames lock sites.
The Environment Agency are reviewing all aspects of our campsite management to ensure we have suitable arrangements in place to meet our statutory obligations and all other legal responsibilities for the sites.
Short stay mooring
Unless signs state otherwise, you are allowed to moor for up to 24 hours at Environment Agency short stay moorings.
You may have to pay a fee at some sites, either for mooring at any time, or after an initial free period.
Signs will usually show any applicable conditions and charges payable. By mooring, you are agreeing to them.
Ask about short stay mooring availability
Call 03708 506 506 if you have any queries, including if you want to pre-book a short stay mooring. You can only pre-book at selected locks.
Additional charges and penalties
You may get a penalty or have to pay additional charges if you do not follow the conditions of use. Penalties could include:
- suspension of your boat registration
- removal of your boat under court order (at the owners expense)
If the Environment Agency has issued warnings for the current river conditions that advise you not to navigate, these penalties will not apply. You should plan to move your boat from the mooring when it is safe to do so.
Electric charging point moorings
Electric powered boats have priority at Environment Agency electric charging point moorings.
Any boat using the electric charging point at an Environment Agency mooring for any length of time will be charged for this service.
You should move a fully charged boat away from the charging point if there is another boat waiting to use it.
During the boating season (1 April to 31 October inclusive) you can only book electric charging point moorings for electric powered boats. Book at least 48 hours in advance by emailing waterwaysthames@environment-agency.gov.uk (monitored Monday to Friday).
Electric charging point moorings are only available for 24 hours and boats must not return to the same electric charging point for 72 hours.
After 4pm any electric charging point moorings not booked will be available to any boat, whether electric powered or not, on a first come first serve basis.
Outside the boating season, the previous information does not apply. However, you must move any boat moored at an Environment Agency electric charging point mooring within 24 hours if an electric powered boat requests to use the service.
