I used to carry loss of license cover, but divorce and tax meant that I could no longer afford such huge expense. I now carry Permanent Health Insurance which pays out an income should I lose my license, and therefore my job. However it only pays until I find another job for which I am "suitably qualified" nasty bit of small print that.
I also insure my mortgage and any other loans I have. The lenders arrange it and it is surprisingly cheap.
