Insurance terminology in the UK has, believe it or not, come a long long way in the past 20 years.
What started as the plain English campaign seems to have been carried forward and insurers are aware that there paying customers do like to read and understand their policies. For this reason you tend to find less long words and best of all, less Latin. There is still a small smattering of Latin kicking around within policies. The position tends to be if the wording still mentions a Latin phrase then it is likely to be one that cannot be reasonably changed.
With the beauty of being able to Google words and phrases, any definitions you are unclear of shouldn’t take long to find out their true meaning. One such word is Quantum, this does not tend to be used in the policies so much but is used in a lot of communication regarding claims.
Quantum is Latin for amount. Under your business insurance policy, if you suffer damage then you make a claims against the policy. However, if a claim is made, it must first be established whether the insurer legally liable to pay the claim or not. Once this has been decided, they will then talk about Quantum, which is simply the amount the insurer will, or is likely, to pay. This will be after deduction of any excess that you, the insured, are liable for as defined in the policy wording.
