If they cannot get you repaired they will recover you to home, or to garage of your choice or even onward to your destination. In fact, to any single destination in the UK.
I also have At Home, so if I go out to my car one morning, and it won't start, they come out and do whatever is required. I have only called them out once, recently, and that was to a failed battery. The guy fitted a new battery for me (had to pay for that) and that was me going.
