履约保函是一种担保书，由担保人签发，向受益人保证履约方将履行合同约定的义务。英文履约保函通常用于国际贸易中，以保护受益人免受履约方违约造成的损失。以下是英文履约保函的一般格式：
履约保函的标题通常为“PERFORMANCE BOND”或“PERFORMANCE GUARANTEE”，居中加粗。
担保人是指出具保函的实体，通常为银行或保险公司。担保人信息应包括名称、地址、联系方式（电话、传真、邮箱）等。

担保金额是指担保人保证履约方履约的最大金额。金额应以数字和字母两种形式表示，并注明货币单位。
履约保函的生效日期和到期日期分别指保函生效和终止的日期。这些日期通常与合同的履约期限相符。
适用法律和争议解决条款规定了履约保函的法律框架和发生争议时的解决方式。通常会指定一个特定的司法管辖区和法律体系，以及仲裁或诉讼等争议解决机制。
担保人的义务是指在履约方违约时，担保人须向受益人支付赔偿金的责任。这部分内容通常包括以下方面：
