I'm full fibre gigabyte snob, I'm getting 1.3 gb per second from Virgin Media, actual speeds around 900mb to 1gb.
I'm hoping for a little more competition in our area, so Virgin can give me a better deal.
Let me just mention this, you don't need this much broadband to enjoy 4K streaming but the more you have, the less compression you get and this makes a big difference in quality if you view a lot of 4k television or movie watching.
I keep checking the availability from Hyperoptic, it seems they're not really keen to venture into Central Bedfordshire. That's a shame.
