When consumers are informed of a new premium, they are not usually reminded what they paid previously. As a result, some customers may not even be aware that the cost of their insurance policy is going up. Now the City regulator is drawing up new rules to ensure renewal quotes include previous premiums as well. That would enable policy-holders to see whether, and by how much, their bill had risen.
Inertia is clearly a very significant obstacle to the working of an effective market. This should be addressed structurally.
