Quote from CAA Safety Sense leaflet 22, Radio Telephony'....
"The phrase 'At your descretion' may be used by a FISO and will follow any advisory information. Pilots requesting departure may be advised:
'Take off at your descretion' or 'Depart at you descretion'
The pilot should not respond by repeating the phrase 'at my descretion' . No clearance has been given, there is no requirement to read ohne back. The Pilot should simply respond 'G-XX roger' or 'G-XX' "...
Think this makes it pretty plain. The CAA Safety Sense leaflets are downloadable from the CAA website and contain loads of useful information. There is also a great VFR guide which is worth reading.
Cheers
