A business might make an offer of 'comparative' or 'alternative' redress if they still believe PPI was useful for their customer - but now think a cheaper or more flexible policy would have been more suitable.
So to put things right, they offer to pay the difference between the cost of these two policies.
But we sometimes hear from people who say they didn't want PPI at all. In these cases, we'll look into how the PPI was sold - and what someone's circumstances were at the time.
If we agree they wouldn't have taken out any kind of PPI policy, we'll usually tell the business to refund all the money they've paid towards PPI.
