The FCA Test case showcased the range of different perceptions about the scope of disease cover. There are residual issues that are likely to litigate but we broadly know where we stand on the core issues. But misunderstandings about business extensions are not limited to disease covers – in particular, utility failure cover is provided generally on two fundamentally different bases (with a hybrid variant for good measure), threatens aggregation over a wide area if there were to be an extensive power outage, and would inevitably reveal misunderstandings about the extent to which the loss of internet sales might or might not be covered. In the light of the above, this session will explore aspects of a power outage scenario and highlight the potential for further disputes mirroring that over covid-19.
