BT is planning to allow consumers to install their own fibre broadband equipment later this year.

BT Wholesale currently sends an engineer to install fibre-to-the-cabinet (FTTC) connections, which incurs an installation fee of around £100, unless the cost is absorbed by the ISP.

However, a leaked BT Wholesale roadmap first obtained by ISPReview revealed that the company plans to allow customers to install their own equipment in the third quarter of this year. BT has subsequently confirmed the plans.

The "wires only" service will require customers to install new microfilters on every telephone extension in the house, as most customers already have to do with ADSL lines.

I'd like fibre to home rather than fibre to cabinet, but there's no way I'd do it myself.

I think the option is pay to get some to do it for you. FTTH would be preferable but how much would that cost?

Once FTTC is finished then then FTTP will start to roll out.

The cost of running fibre is expensive if it's just for one premises and it has to go back to the exchange. If there's fibre in a street cab then the cost will be reduced due to a reduced fibre length (but don't expect true 1gb bearers on this) but to make it truly affordable BT will need to do what cable did in the old days and dig up all the streets to run tails from the street cab to either the outside of every building.
This would mean a very short run of fibre to a premises when they decided they wanted FTTP and an install cost of less than £80-100 or so.

There are homes that are still connected to telephone poles IIRC. For them it would a matter of connecting from the pole to the home. Though longer term BT will need to invest in more fibre and they can at least offset it with the sale of copper once they have completed the transition.

Fibre is always buried, it doesn't like swinging in the wind.
They also still need the copper for phones (until everyone moves over to IP phones via broadband.

Doubt it.
Didn't I read somewhere that they could run fibre through drain pipes?
