No PMI covers medical bills etc. Income replacement covers illness etc. Depending on what cover you want it can be very expensive and will only cost a maximum 75% of salary.
It can cover inability to work after an accident ands the definitions on what injuries are covered are tightly defined and generally cover loss of limbs, sight either on a temporary or permanent basis.
You then get in to any or own occupation-that is do you want cover for not being able to do your own job or not. For example if you’re a surgeon do you want cover for if say you lost the use of a hand and couldn’t operate any more or would you be happy if you were covered only if you couldn’t do any job at all (you could for example still be an office bod in this scenario).
Cover for just being ill-even long term-is available but is very expensive and would be subject to extensive underwriting.
Illness cover is more commonly seen on a group basis (that is bought by a company to cover all their staff, generally as a benefit).
PMI is pretty simple but unless you’re prepared to spend ££££££ any preexisting conditions would be excluded. It is still quite expensive in any event.
If you’re seriously looking at income protection I’d suggest seeing an insurance broker as it can get pretty complicated.
I’ve only ever had either as part of my overall package at work.
Happy to answer any other questions. Have just finished a project developing a training package on this stuff and it’s reasonably fresh in my mind!
