"It's permitted development so no approvals needed" Wrong. PD means no planning permission. Building regs still required.

"Building control signed it off" Great, but did you need planning too?

The Safe Approach

1. Check if planning needed (permitted development?). 2. Apply for planning if required. 3. Submit building regs application. 4. Get both approvals before starting. 5. Building control inspects during construction. 6. Get completion certificate.
