Does the Broadband Checker have old data? Or is it the case although the exchange has been upgraded, the cabinet has not? If the latter how do I find out when the cabinet will be upgraded?
If superfast broadband is unavailable, then I may consider line bonding, but I would rather not get into a 12/24 month contract for that service - with independent suppliers - if BT will be offering FTTC shortly.
Up until recently you could email Openreach and ask when your cabinet was likely to be upgraded however Openreach are no longer giving out that information, instead they are replying:-
Thank you for your contact to us. Please note that we will not be responding to you by email but, would like to point you to the Openreach Superfast Fibre website and the FAQ section that will provide answers to the most commonly asked questions. It will also provide links to those service providers that sell fibre broadband at the moment so you can check if your particular line is enabled.
