sorry but FTTP is not fed from the exchange
unless checker shows your address can get FTTC OR FTTP you will not be able to order
Are you sure about the FTTP not being direct from exchange?
Openreach disagree as do I, the cables in my pictures do not go to a cabinet I have traced them!
FTTP comes from the headend which may or may not be located in your exchange.
From everything posted I cannot see WBC FTTP being available to you. I hope for your sake I'm wrong. Wait and see what the reply is from Openreach.
I live nearby in Lawnswood and we had similar problems. Your best bet is to organize a community partnership (see https://www.openreach.com/fibre-broadband/community-fibre-partnerships). If you can get your neighbours to agree you can get per HOUSEHOLD grants of up to £1,500 (Government) + £2,000 (via Superfast Staffordshire). In our village we qualified for grants of up to £200,000. You then get Openreach to give you a quote to do the upgrade. In our case, it was all free because the cost was only £40,000 for the entire village. I strongly suggest you contact www.superfaststaffordshire.co.uk as they are brilliant and will help you get it all sorted out.
