No, I don't think I'll do it through the insurance, I'll take this one on the chin. Having had a look this morning, the black lower grill is borked, the lower rim of the bumper that goes underneath it is split in two, rads have been pushed back and sliced in two. Can't see any other damage, although I reckon the A/C maybe knackered as the condensor is piggy backed onto it.
Went back this morning to see if there were any salvageable parts, the deer is sat at the side of the road. Rang the 101 non-emergency police number who took my details, said there's nothing else by law I have to do, they will contact the local authority to either dispatch it or pick it up.
Still absolutely gutted though.
