Service updates on Twitter

  • Our fleet control update Twitter with delay information using TfL’s wording for delays. “Minor” refers to delays between 5-15 minutes. “Severe” refers to delays that are over 15 minutes.
  • When a service is “suspended between two piers” this means that the service is not able to run between the piers mentioned or at the intermediate piers.
  • We cannot always give a specific reason for each individual delay nor can our fleet control respond to individual tweets asking about the arrival time of your service.

What causes service delays and alerts?

Spontaneous service delays can be caused by a number of issues including river congestion, pier congestion, passenger demand, passenger disruption and occasional technical issues with our vessels. When we are aware of these disruptions, a service alert is issued via our Twitter page.

Anticipated service alerts can be caused by:

  • Tidal conditions
    At extremely low tides, our vessels may be unable to dock successfully at some of our piers or it may be unsafe for passengers to attempt to board from them. Low tide also limits the Thames’s river traffic capacity which can cause congestion.
  • Thames Barrier closures
    The Thames Barrier is located between Woolwich (Royal Arsenal) and Royal Wharf piers. When the barrier is closed for tests, or to prevent London from flooding, our services are unable to reach Woolwich (Royal Arsenal) or Barking Riverside piers.
  • London fog
    In extreme fog our services cannot operate. As foggy conditions can change rapidly, please check our Twitter page for the most up-to-date information.
  • Riverside activities
    The Thames is an incredibly active river and events regularly take place along its banks and on the river itself which have the potential to affect some services.

We apologise for any inconvenience that service disruption has caused to your journey and we always appreciate your patience while we manage the matter. If you wish to contact our Customer Service Team, you can do so here.
