Presumably you are looking for something like PHI (Permanent Health Insurance), Critical Illness insurance, salary protection and/or general life assurance (which pays out on death and might be purchased separate from any mortgage protection life assurance assigned to the mortgage lender) in order to ensure that loss of your job through illness or disability does not leave you and your dependents in dire straits? When looking at these policies pay careful attention to the charges/premiums and to the detailed terms & conditions governing in what circumstances, for how long and how much these policies will pay out. If in doubt get independent, professional advice at least by going through a decent multi-agency intermediary/broker.
