In Sky v Riverstone, it was held that the main contractor, who was appointed pursuant to a JCT contract, was not insured under an owner controlled insurance programme following practical completion, because it no longer had any rights or interests in the property insured. That decision has not been appealed. Consequently, main contractors (and their brokers) will need to review and carefully consider both their construction contracts and project insurance arrangements, to fully assess their coverage and joint insurance position in respect of post practical completion losses. Failure to do so could leave them exposed to subrogated actions by project insurers.
