perhaps some questions to think ab out
when you die, do you want a lump sum to go to your spouse/children? if so, you should get life assurance
If you get a very serious illness, which may or may not be cureable, do you want a lump sum? if so you should get critical illness insurance
if you get ill and cannot work, do you want money on a monthly basis to cover you until you go back to work or until such time as your pension may kick in? then you need income protection, also known as permanent health insurance (nb you can get more than 60%)
with any of these it is up to you to determing the level of cover, ie percentage of income, mortgage etc. anything is technically insurable... but at a cost!
also you may want to check what your work (if you do work) covers you for, many people have a death in service benefit.
it is a good idea to get and IFA to help you with this if you are starting out but it is not a substitute for keeping yourself up to date!
