Additional Increase in Cost of Working

An optional extension under a business interruption insurance. It allows you to incur reasonable additional expenditure to avoid or diminish any further reduction in turnover following a loss even if the amount payable exceeds the saving made. Without this extension you would only be able to recovery additional expenses that are economic and agreed by the insurers i.e. they will only agree to spend £1 to save at least £1. The extra cover is for a specific sum.
