Documents that prove your identity and address

Like all financial institutions in the UK, we're required by law to check your identity and address when you apply to invest with us or register for our online and phone service. We might also need to check your identity at other times, to keep our records updated.

How we do this

We normally check your identity and address electronically through a credit reference agency. If this is unsuccessful, we'll ask you to send us some documents instead or upload copies of them online. Here we explain which documents you can use and how you can certify a copy of your document, if you need to.

Most of this information is for savers aged 18 and over living in the UK. Our requirements are different for:

• Savers aged 16 or 17
• Savers aged under 16
• Savers who live outside the UK

What you need to send us or upload

• One document from List A: evidence of your identity; and
• One document from List B: evidence of your address

Note that you can’t use the same document for proof of both your identity and address.

For valuable documents such as passports and driving licences, we recommend you use copies instead of the originals. If you send or upload a copy of any document from List A or List B, other than a GB passport or GB/Jersey driving licence, it must be certified – we explain how to do this below. If you do choose to send originals, please use a secure postal service.
