I went for the 2Gb package, but there was a delay in getting an engineer out as they send their own engineers for the 2Gb and faster (because the routers are expensive and they don't hand them out to contractors). I ended up paying for a static IP to be able to access my network remotely - Via VPN so I can fix my wife's working at-home IT issues whilst away! - traditional DDNS does not work with CGNAT.
Their support staff have been very helpful at every contact as was their engineer who carried out the install for me. A few things of note, static IP is tied to the router so when I changed router I had to contact support to get them to reset the cache on their end, initially I had reliability issues, turns out the 2.5Gbe network cable supplied with the ONT and used by the engineer was of poor quality, having swapped it for a length of Cat 6A all the stability issues vanished.
I didn't use their router (Asus ET12 Pro) as it didn't have a dedicated wireless backhaul channel and didn't integrate nicely with my existing mesh, instead opting to purchase an Asus BE-98 which is happily providing the max speed my devices support.
