Thanks for your post and it's great to hear that you are looking at having Virgin Media installed.
As much as we would love to be able to install everybody, sometimes it's just not possible. There are some streets where some houses have been cabled and others haven't so your issue isn't as uncommon as you'd think.
We already have a full 2019 roll out planned as well as some of 2020 for new areas and New Builds too but we won't be doing any more in-filling now.
I can double check to see if your area is in the plans for this year although I'll need some information from you. I have sent you a private message requesting some information. Just click on the little plum envelope at the top right hand side of the page to access your inbox.
