One of our clients had a group of employees, each with their own individual private medical insurance policy. Whilst it was great that they had cover, the expensive individual premiums had meant they'd cut the benefits quite drastically to make the policies affordable. However, there can be significant savings to be had by merging all policies onto a 'group' scheme.
With our knowledge of the industry, it was possible to make this change with no further exclusions added and even an enhancement to the benefits.
