Yes, it’s possible to add your partner and children to your cash plan policy, but it depends on the type of cash plan you have.
If you can add a partner on your plan, they can only be accepted initially on the policy if they are aged between 18 and 69. A partner is:
a husband
wife
civil partner
or the person that you live with and are in a relationship with similar to that of a marriage or civil partnership
If your cash plan allows you to add child dependants, they are only eligible to be members if they are:
under 24 years old
living permanently in the UK
We define dependants as any child of yours or your partner’s. This includes any child for whom you or your partner is a legal guardian or foster parent. Once your child dependants are accepted as members, they can continue to be covered under the policy until the end of the month in which they have their 24th birthday, at which point their cover will end automatically. We will cover a maximum of four child dependants on the policy.
