How can I get an IHD In home display

Hi I switched from Scottish power to bulb over a year ago and I have never gotten a IHD, I can’t find an article or anywhere on the app / site to apply for one. It just states that you get one when an engineer installs a smart meter from bulb? So how do I obtain one thanks!

Im the same, got smart meters fitted but wasn’t offer an IDH.

Hopefully able to get one now.
