His recruitment is now subject to formal appointment by the Queen before he can replace outgoing auditor general Huw Vaughan Thomas when he retires in July.
Vaughan Thomas said: “I am looking forward to engaging with Adrian and colleagues to ensure a smooth transition when I hand over the reins in July. I wish Adrian the very best with what is a privileged, challenging, but exciting role in Wales.”
Isobel Garner, chair of the Wales Audit Office board, said she was looking forward to Crompton joining the organisation.
“I’m confident that Adrian will build on Huw Vaughan Thomas’s legacy and will continue to transform external audit in Wales so that it makes a real difference to public services and people’s lives,” she said.
Crompton currently works as director of assembly business at the National Assembly for Wales.
