Unarranged overdrafts

If you don’t have an overdraft with us, your balance can still go below £0. This is called an unarranged overdraft.

We try to reject any payments that would take you below £0. But we can’t reject payments that happen offline, like Transport for London and in-flight payments, and work using a pre-authorisation like car hire or hotels.

Some transactions to Monzo can also take you into an unarranged overdraft including:

your monthly subscription to Monzo Plus, Monzo Premium or Monzo Max if you’re in your minimum term
if you’ve had an upfront refund for a dispute but we haven’t got enough evidence to uphold your claim and need to take the refund back
your first Monzo Flex payment if you've made a purchase on your virtual card and not chosen how many months you’d like to pay it over

We also don't charge you interest or fees when you’re in an unarranged overdraft, or for payments we reject.
