This type of protection covers you for a set term for an increasing lump sum. The level of benefit will be agreed at the outset. The benefit amount for this type of policy rises annually by a predetermined factor, typically Retail Price Index (RPI). This is referred to as as "indexation". However, with this policy, as your benefit amount increases, the premium will also increase. By selecting indexation, you are protecting the purchasing power of your selected benefit. This might be suitable for family protection, but again this would be totally dependent on the individuals requirements and circumstance.
