To me, this stinks of INERTIA SELLING which was outlawed a few years ago. A quick look at Wikipedia shows that this seems to come under the Distance Selling section of the Consumer Protection Regulations of 2000.
INERTIA SELLING means that the seller takes it for granted you want to buy his product, and charges you for it, whether you have ordered it or not. In the case of my car insurance, the seller claims to have my interest at heart. In very small print on the contract (smaller than what you are reading now), I read that I will be charged if the cover is issued (without my consent), if I chose to buy cover elsewhere.
This practice is so close to dishonesty that customers need to be very alert when buying insurance. I admit to being almost OBSESSIVE about cutting motoring costs. But how many other motorists end up being caught out in this way?
We can always rely upon Big Business to find a way to con us. It wouldn't surprise me at all to find that they have found a way around the Inertia Selling bill of 2000.
And isn't there something repugnant about an insurance company retaining details of my credit card for a whole year so that they can charge me without my consent? This is no better than those crooked restaurants in holiday resorts which used to copy card details then charge transactions to the card after the customer had returned home.
