The below information was accurate at the time of publishing. It will not be updated with daily changes.

Single sited - one lock keeper working at one lock during a working day.

Double sited - one lock keeper working at two locks during a working day. Time during the day will be split between two different locks. Therefore there will be periods of the day when each lock will be on self-service.

Treble sited - one lock keeper working at three locks during a working day. Time during the day will be split between three different locks. Therefore there will be periods of the day when each lock will be on self-service.

Self-service - no lock keeper working at the lock.

Assisted passage will be offered if a lock keeper is on site during the Lock keeper hours of duty. This is except for staff breaks, weir work and maintenance.

Public power will be provided at all locks where available, when assisted passage is not being offered by a Lock Keeper or volunteer. This is unless we are unable to do so due to circumstances outside of our control, such as power outage or breakdown.

More information about our assisted passage target is available in our River Thames Customer Charter.
