Broadband speed is good, we get mid 70s mbps download.
As the "Green box" is less than 200m from the house we could get fibre to the house, but the Openreach installation is expensive and I don't see the need.
We have fibre to cabinet, and for about 6 months after installation we were only getting about 30Mb until I asked BT to have a look at the external wiring. A keen young engineer came out and pronounced our external cable as being "older than the stuff my Dad worked on".
So he replaced the wiring from pole to house, and now we get a rock steady 78Mb, which is plenty for watching streaming movies. No charge either, which was nice.
So like Peter we're struggling to see why we would want fibre to house, even if it were to be available.
