Why are you titting around with glands, just treat the SWA as flex and terminate it as you would, if the SWA cable is in the wall cavity then it doesn't need the SWA protection anyway and it will still be armoured, just not earthed. The piece coming from the house or wherever can still be glanded I presume so that will satisfy the buried cable regulation.
When we wire brick lights, we just put in copex first and pull the flexthrough as we are doing the brick lights, it doesn't need any more than that.
