PLA River Works License
River Works License & PLA Consent Support (Tidal Thames)
Works within the tidal Thames and Port of London often require consent from the Port of London Authority (PLA) in the form of a River Works License. In many cases, this sits alongside an MMO marine license, creating confusion around responsibilities, sequencing and scope.
TILT Engineering & Design provides clear, joined-up support for River Works License applications and associated marine consents, helping clients navigate PLA requirements and avoid costly delays.
When is a River Works License required?
A River Works License is typically required for works that:
Affect the bed, banks or channel of the River Thames
Involve structures, dredging or temporary works in the river
May impact navigation, tidal flow or river users
This includes works such as:
Quay, jetty or river wall repairs
Temporary cofferdams or piling works
Outfalls, intakes or riverbed disturbance
Maintenance or modification of existing assets
PLA and MMO – understanding the difference
One of the most common issues we see is confusion over whether a project requires:
A PLA River Works License
An MMO marine license
Or both
In many cases, both authorities have jurisdiction. Understanding how these consents interact, and ensuring applications are aligned, is critical to keeping projects moving.
Avoiding common causes of delay
River Works License applications are often delayed by:
Insufficient technical detail
Poor alignment with construction methodology
Failure to consider navigational impacts
Late identification of overlapping consents
Early, informed input reduces risk and avoids re-submission.
