The most common type of life insurance is ‘Term Life’ and continues for as long as you want it to. Cover can be level or linked to the consumer price index.
Also, premiums can increase each year (annually renewable) or can be fixed for a term, e.g. 5 or 10 years, or level to age 65, 70, 80, 90, 100. Many live insurance policies will pay out the entire sum insured, or a portion, on the diagnosis of a terminal illness. This give you money to live on or pay for care if you are incapacitated and can’t work.
