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.
