Hence you have a very competitive market landscape in the UK. There are at least 5 major national retail players using various wholesale products (BT, VM, TalkTalk, Sky, Vodafone), plus dozens of altnets offering FTTH on totally seperate fibre infrastructure have started (Hyperoptic, Cityfibre, GNetworks, Community Fibre).
In my flat in London I have access to 4 seperate FTTH networks (with completely different infrastructure) - Openreach FTTH, VM DOCSIS, Hyperoptic FTTB and Community Fibre FTTH. The market works here, prices are low and there are very few data caps.
