Has anybody got any advice??

I crashed into another car on tuesday , didnt damage the other car in any way but my front end(body work, radiator, engine etc )was all crumpled.

My car has been takenn away this morning for examination to see if its repairable or a write off.

If its a write off,
1.do i still have to pay my excess?
2.can i pay to get it back and roughly how much does it cost?
3.do car garages except write offs in the scrappage scheme still?

Any advice would be helpful asap

Cheers
