When looking for business insurance, you will, in over 90% of cases, end up speaking to an independent broker to get a competitive quote.
As part of this process, you will either speak to them over the phone or have a face to face meeting. When this occurs, there will be a large amount of information that they will ask of you, in order that they can present the risk to insurers to get the best price for the widest cover.
One of the questions, if you are selling products, will relate to the actual stock that you hold, and need to insure, at the business premises. For a wholesalers insurance quote, the two main questions will be what is the type of stock that you hold, and what is the maximum replacement cost. This cost is the amount you need to have cover for, so in the event of a loss you are fairly recompensed by the policy.
The dfficulty for a cash and carry business is actually defining the stock that hold. For a sweet shop, this is easy. But a cash and carry can have tens of thousands of different product lines, from meat, to sweets, to paper plates.
If you do not declare the correct type of stock, ie the sweet shop does not declare it has (much more theft attractive) tobacco stock, then if there was a break in the insurers could, quote fairly, turn down the claim.
So, the cash and carry owner want to be sure that they are adequately covered. One way of doing this is to get an insurer that has a specific business category for cash and carry. This way, in the event of a loss, if you can prove that the product line you are claiming for, is one that you or any other similar business would more than likely sell, then you will not have a problem in getting any claim settled.
As ever, speaking to a broker is the best, and easiest way to do this.
