It's an interim state for hysterical reasons    The previous packages were two ADSL and two FTTC with data limits on the lower cost option for each type. With the latest change, the package I am on was removed as an option and only unlimited ADSL remains (66% extra cost) - presumably, I am in a small minority who don't think I need unlimited data I suspect the retention of a slower FTTC package upgraded to unlimited may be to both encourage people to switch from ADSL and to silence those who would be vociferous should they pay for (up to) 80Mb/s and only get 30Mb/s, as well as pass on the underlying cost differences

Perhaps I should complain that I pay for (up to) 16Mb/s and get 3Mb/s (though that's better than others are getting and good enough for most of my needs).
It is claimed I could get maximum 80/20 speeds with FTTC, being <130m from the cabinet ( at a 233% increase in cost)

Hi,
There should be no setup costs at all if you have home phone with us. I have just activated the phone component on your account so the prices may show slightly differently now.
As highlighted by PeeGee; we made all the packages unlimited recently so I suppose that speed limitations were the only other variable that could have been used to dictate a difference in price.
As you have just gone through the process of a house move, I'd imagine you may have been offered slightly different prices over the phone in comparison to what you can see on the website or the account change tool.
@PeeGee - Whilst it is more expensive, it may be worth checking what our Customer Options team can offer if you ever feel like you need to be on unlimited at any point. It's not unheard of for them to match the prices of the older package.

Matty,
I have been thinking about a change for a while and have started a thread here
