She'd be looking at about €160 a month for income protection of €30,000 to age 65 with a deferred period of 6 months. As Dave said, there will be exclusions for pre existing conditions. It could be a decline though depending on the mental illness. The company can pay the contributions.
There is no issue in her taking out the cover through her company and her still being in receipt of income as long as her total income through the income protection, salary and state disability does not exceed 75% of salary.
Life cover is about €93 per month. She can take out cover through her company but that is limited to 4 times salary. If she pays herself a bonus and her total income is €75,000 or over, I would recommend it paid for through her company. Otherwise, do it personally. Another consideration is doing life of another where the beneficiary of the cover is the owner of the cover and pays the premium. By them being the owner, it avoids probate and is paid out much quicker.
