The Environment Agency carries out a programme of works on the River Thames every year between October and the end of March. This results in the closure of a number of locks sometimes for relatively long periods.

The first issue of the programme is published in August each year. This is so that river users can plan their winter cruising and boat movements well in advance.

This programme of work is subject to change, due to weather and other circumstances. Revised issues of the programme of works are published throughout the winter, so river users can keep up to date. To receive this information, sign up to the email update service.

Investment programme October 2022 to March 2023
