The fact that night VFR is not allowed in the UK is an airspace rule. Therefore it applies to all aircraft in UK airspace but has no effect on any aircraft outside of the UK.
Choice of VFR or IFR
22 (1) Subject to paragraph (2) and to the provisions of rule 21 an aircraft shall always be
flown in accordance with the Visual Flight Rules or the Instrument Flight Rules.
(2) In the United Kingdom an aircraft flying at night:
(a) outside a control zone shall be flown in accordance with the Instrument Flight
Rules; or
(b) in a control zone shall be flown in accordance with the Instrument Flight Rules
unless it is flying on a special VFR flight.
