The Insurance Act 2015 ('the Act') is the first comprehensive statutory reform of the insurance law of the United Kingdom since the Marine Insurance Act 1906. This book is a thorough introduction to the Act. It focuses primarily on the impact of the Act on English law as applied to non-consumer insurance and reinsurance. Of assistance not only to insurance lawyers and members of the judiciary, but also underwriters, claims handlers, brokers and buyers of non-consumer insurance policies, this book covers each of the core changes brought about by the Act. It also analyses the particular ways in which the Act differs from existing law, by reference to the Marine Insurance Act 1906, and cases decided under the old law.
