Third party mandate

A third party mandate is a formal instruction from you to HSBC UK. It tells us that you’d like someone else to carry out everyday banking transactions on your HSBC UK bank account.

These don't include arranging a formal overdraft or opening or closing an account for you.

You might consider this option if you need help managing your accounts, for convenience or because you don’t have access to them.

For example, if you're recovering from an operation you might want someone to pay your bills.

Table of contents

Please note, before deciding if a third party mandate is right for you, you should consider other options.

You’ll find more examples of when a third party mandate may be suitable in our ‘Understanding third party access’ table.
