If you submit the cost for the project wrong during the quote, or become aware that it is costing more than anticipated, you can correct this at any point. You will just need to reach out to your insurer or broker and ask for it to be adjusted.
There is a direct correlation between coverage and premiums. Simply put, the higher your coverage, the higher your premium. To deter people from purposely underinsuring your project to get lower premiums, insurers retain the right to apply the average clause and only pay out a proportionate amount for what you are claiming based on how much you are underinsured by.
For example, if you underinsured your project by 50% and you need to make a claim, the insurers have the right to underpay the claim by 50%.
A policy does include automatic uplift under both the buildings and works heads of cover. If the disclosure of sums insured at inception can be shown to have been reasonably and fairly estimated, then the policyholder will benefit from this protection in the event of a claim – if the sums insured have been accidentally understated.
For larger projects, particularly when high-end fit outs will occur, it is often not possible to accurately estimate the final spend. In these circumstances, we can issue the cover on a declaration basis, whereby the amount you declare would be the total amount you would be covered for. If, as the project progresses, that the actual costs are higher than the declared amount, then get in touch with your broker or insurer who can make the adjustment.
