... is a line i'd expect from a dealer selling a Bike and wanting to haggle.
NOT from a business that employees an Actuary.
Definition of actuary;
a person who compiles and analyses statistics and uses them to calculate insurance risks and premiums.
The keyword being calculate.
How can the insewerance industry be taken seriously when it is a game of horse trading and haggling to get the best deal?
It's quite simple really. The underwriter will offer Carole Nash a price for a service. CNash is merely an intermediary but as a registered company it has a duty to maximise profit for the shareholders. It can charge whatever it likes on top of the base cost. In this case, the sole shareholder is a French mutual so you should feel good about subsidising the insurance and pensions of French farmers.
The onus is on the buyer of the insurance to seek the best deal, not on CNash to provide it. It's no different to choosing whether to buy a new TV from Currys or John Lewis.
