Changing your overdraft limit
You have the option to change your overdraft limit. But bear in mind you can’t change it to above your maximum, or to below any amount you’re already using.
Please be aware that if your credit file's changed since you last adjusted your overdraft limit, the amount that we're able to offer you may be subject to change.
Here's how to change your overdraft limit in the app:
Tap Home in the Monzo app
If you see your account list, tap on the name of the account you need
Tap the Manage tab to the right of your transaction feed
Tap on Manage overdraft
