When Iíve questioned Openreach on their decision they have either :
a) given me a generic response saying that there are no plans for my area but community fibre funding is available ( yet half the estate have been upgraded by Openreach for free!)
B) ignored my e-mail
C) responded and informed me that my property was not on the database and would update me which they never did and then failed to respond to a subsequent e-mail from myself.
Your developer is entirely to blame.
OpenReach didn't just randomly install FTTP for free to the newer properties. The developer will have ordered this from OpenReach (it is free, but only if you bring OpenReach onboard at the very start and build everything to their requirements).
You have 3 options.
1. Pressure your developer to pay for OpenReach to install either FTTC or FTTP. If they are still building/selling homes a sign in the garden stating how poor the internet is often gets noticed.
2. Community Fund it.
3. Do nothing and hope OpenReach eventually cover you, wether that be commercial or BDUK funded.
