Is a postcode checker result final ? Postcode PA19

Being in the process of moving from a long time Plusnet fibre connection that has dwindled to what I hope is a shiny new phone, TV, and Vivid200 internet package,
I'm wondering if the likes of the Vivid300 could be offered in the future ?

We were cabled in the summer with only half our small town Gourock PA19 previously laid. So I don't know if this will be fibre or coaxial etc

Yes, in the future all properties will have the 300Mb products available.

After the bad publicity last year VM have been careful with the areas they have been releasing it. New areas do not have loads of bandwidth unused. It is easier to increase the bandwidth there than in older areas but new builds can fall behind a bit if the sales bots do too good a job or too many people like me sign up, and they may need remedial work.

Thanks.

Its all new to me. I've had a look around VM's pages, and a quick look at their forum. I think what I need is a TB VM FAQ
