I'm agree with Mr Saffron.
Actually the opposite
GC prefer well established rural villages where there are not going to be lots of new houses.
As their FTTP type architecture is point to point from a central village cabinet - it is more difficult to add in lots of new subscribers later than if it was GPON.
The number of unused fibres in a cable would be a relevant issue
Actually GC staff did tell me at one stage that they don't like new builds as its just a lot of aggro talking to the developers let alone agreeing - they prefer to talk to the owners of established houses with an incentive to get decent broadband from themselves and done properly.
Added to which developers argue over wayleaves/legals for ages- property owners sort this sort of thing out overnight - sign the form job done when can you start installing sort of thing.
A new build estate would be a target for BT. I think GC want to avoid any head on competition with BT as they need a 30% takeup to make the projects economic.
Note that GC only install the network at their cost to the property/land front boundary termination point. The cost of getting the fibre from there across the garden to where you want it in the house is at the cost of the householder. this is how they keep things cheap and quick: the difficult bit is paid for by the house owner.
The cost really depends on how a particular property is connected. Where I live GC suggest that if you want someone to complete a connection you should ask Boxcom. These are the people who joined up the network when the cables had been laid by Wingnut, and I think manage the cabinet hardware. The ones I saw were all ex Gurkhas.
PS I'm on a Gigaclear connection.
Ditto - for the last 5 months
