Regulation 6 Duration of temporary permits
A temporary permit shall cease to have effect on whichever of the following dates falls first—
if a London PHV driver’s licence is granted to the holder of the temporary permit, the date on which the licence was granted;
if an application for a London PHV driver’s licence by the holder of the temporary permit is refused, the date on which the time for appealing against the refusal of the application expires or (where an appeal is brought) the date on which the appeal is disposed of or withdrawn;
if the temporary permit is revoked, the date on which the revocation takes effect in accordance with section 17(1) or (2) of the 1998 Act; or
if the temporary permit ceases to have effect in accordance with paragraph (3), the date specified or agreed as mentioned in paragraph (2).
If an application for a London PHV driver’s licence is not received from the holder of a temporary permit by the application deadline, Transport for London may give notice to the holder that, if an application is not received by Transport for London from him by the date specified in the notice or such later date as Transport for London may agree, the temporary permit is to cease to have effect.
If no such application is received by the date so specified or agreed, the temporary permit shall thereupon cease to have effect.
