There is nothing in the contract to roll it eventually out to customers.
LFFN contracts are for schools, council offices, etc.
Nothing residential.
A new player in the area winning the contract might increase the likelihood of a future residential rollout but not necessarily so.
OpenReach already have Aggregation Nodes all over the place so it wouldn't have made much difference to them doing a future rollout of FTTP.
Cityfibre have dark fibre in Manchester anyway so winning this contract would be unlikely to suddenly trigger a residential rollout.
If it had been a full fibre company then they would have had the natural incentive, VM won't. I suspect consumers will eventually be moved to docsis 3.1 when that comes around.
If Virgin aren't a full fibre company then I'm curious to know what that glass string with light inside is that I'm using right now for internet access.
Virgin have already upgraded Manchester to DOCSIS 3.1 and the 1gig packages are available to consumers.
