'If the VFR ac is VMC and the IFR is IMC then as long as the VFR is clear of cloud then hthey are separate' not sure what the ATCEB would say to that. 1000' QFE is our separation standard for Mil against Civ, only in exceptional circumstances and if the Civ pilot is happy do we reduce to 500'. The bottom line is if the VFR is not visual with the IFR then he must avoid.
