Article 52 is pretty definitave:
Pre-flight action by commander of aircraft
52 The commander of an aircraft registered in the United Kingdom shall take all
reasonable steps to satisfy himself before the aircraft takes off:
(a) that the flight can safely be made, taking into account the latest information available as to the route and aerodrome to be used, the weather reports and forecasts available and any alternative course of action which can be adopted in case the flight cannot be completed as planned;
Its the Capts responsibility not that of ATC!
