The use of electronic cigarettes has been banned on trains, buses, Tubes and stations across London by Transport for London (TfL), with passengers caught ‘vaping’ potentially facing a fine.

The ban came into effect in August, but was only confirmed on Wednesday by TfL in order to minimise the response from passengers, The Evening Standard reports.

E-cigarettes were already banned on the Tube, but now the "conditions of carriage" has been changed to include all premises owned by TfL.

New rules implemented by TfL state: "For safety reasons, on our buses and trains and in our bus and Underground stations you must not smoke or use an electronic cigarette ('vape').

“You may be prosecuted for disobeying these requirements."

Jill Collis, Director of Health, Safety and Environment for TfL, said: “The full inclusion was brought in this August to remove potential for confusion and allow staff to approach any customer either smoking or using an Electronic Smoking Device with confidence, ensuring that the No Smoking ban is fully enforced.

"This would mitigate any residual potential fire risk and reduce the potential for staff assault by providing clarity and consistency in the treatment of all customers using our services.”

The ban does not prevent vaping at bus stops.
