From the report:
1.16.1 Effect of flap selection
The aircraft manufacturer carried out an analysis of the final approach of G‑YMMM’s accident flight to establish the effect of selecting flap 25 at around 240 ft agl. The analysis concluded that, had the crew left the flaps at flap 30, the aircraft would have touched down about 51 m (168 ft) short of the actual touchdown on the accident flight, still within the airfield boundary.
and:
Had the flaps remained at flap 30, the touchdown would have been just before the ILS antenna, but still within the airfield boundary. The effects of contact with the ILS antenna are unknown but such contact would probably have led to more substantial structural damage to the aircraft.
