Cannot access cost explorer despite being admin

If you can access Billing in other accounts and not this, then it sounds like IAM billing access has not been enabled for this account or you have an SCP at the ORG level blocking billing.

Hi Gary,

The link above shows these steps:

Activating IAM access to the AWS Billing and Cost Management console

By default, IAM roles within an AWS account can't access the Billing and Cost Management console. This is true even if the IAM user or role has IAM policies that grant access to specific Billing features. The root user can allow IAM users and roles access to Billing and Cost Management console by using the Activate IAM access setting.

To provide access to the Billing and Cost Management console

Sign in to the Account page in the Billing and Cost Management console at https://console.aws.amazon.com/billing/home?#/account.
Under IAM user and role access to Billing information, choose Edit.
Select Activate IAM access.
Choose Update.
For more information about this feature, see Activating access to the Billing and Cost Management console.

Using the https://console.aws.amazon.com/billing/home?#/account link only shows the Billing and Cost Management home page, within this, there is no section named 'IAM user and role access to Billing information', or any option to Activate IAM access.

Is this a AWS console option that is only available when signed in as the root user?

In addition, we have no restrictive SCPs enabled in our organisation' s management account.
