Good to know
Confirmed free on TfL's Woolwich Ferry page ('The ferry is free'). Both banks are inside the ULEZ, so non-compliant vehicles still owe the ULEZ daily charge. Service can be suspended in extremely high tides or dense fog.
Pay only on the official site linked above. Look-alike sites charge extra fees. This page is general information, not advice. Always check the official page before you travel.
