英国的誓言比较简单，只强调对王室的忠诚。英文原文如下：

  I, [name], [swear by Almighty God] [do solemnly, sincerely and trulyaffirm and declare] that, on becoming a British citizen, I will be faithful and bear true allegiance to Her Majesty Queen Elizabeth II, her heirs, and successors, according to law。

  参考译文：

  我(姓名)(以上帝的名义)庄严宣誓：在成为英国公民之际，我将根据法律忠实地效忠于女王伊丽莎白二世陛下，她的后嗣和继任者。

  自2004年1月1日起，申请成为英国公民的人还被要求作出如下承诺：

  I will give my loyalty to the United Kingdom and respect its rights and freedoms. I will uphold its democratic values. I will observe its laws faithfully and fulfil my duties and obligations as a British citizen。

  我将忠诚于大英帝国，尊重它的权利和自由。我将支持它的民主价值观。我将切实遵守它的法律，履行作为一个英国公民应尽的职责和义务。
