Just wanted to post up the solution for getting the Ubiquiti Cloud Gateway Ultra Router working with the BT EE IPTV boxes.
I stumbled upon the UDM-IPTV plugin over on Github and installed it to my UCG. During the install it asks some questions such as TV provider and then it will configure the router for you.
I now have my EETV Box Pro and Mini both working perfectly. I have connected the mini using a ethernet cable as over WIFI it was very stuttery and picture kept breaking up. I havent had chance to look into this further but i'm happy for it to stay wired.

If the link does not work, just google UDM-IPTV Github and you will find it easy enough.
Thankyou @naylor2006 and everyone else that offered their support!!
