倫敦保險市場於國際海上保險市場具領導地位，英國於1906 年制定之海上保 險法，對全世界海上保險實務運行暨海上保險法制有舉足輕重之影響，各國保險 法或海上保險法之制定或修改就此亦多所參酌。擔保條款為海上保險契約要求或 禁止被保險人從事某行為之條款，目的為對保險人之賠償責任加以限定。於英國 海上保險法，就擔保之要件暨被保險人違反擔保之法律效果頗為嚴厲，因此遭致 諸多批評。 於2014 年7 月17 日，英國法律委員會提出保險法修正草案予英國國會，並於 2015 年2 月12 日經其審議通過，即－英國2015 年保險法，本法於2016 年8 月 12 日正式施行。本法對百年來之英國海上保險法為重大變革，就擔保條款而言， 其將被保險人違反擔保之法律效果改變、並廢除保險契約基礎條款之規定。鑒於 英國保險法制對於全球保險市場有重大之影響，本文即就英國新訂保險法有關擔 保之部分加以深論。
