Can I get fibre?

Looking to move and the property has no working phone. Just 3 properties (all next to each other) in post code and all three lines come across the field together.
The BT checker says the other two can have fibre, it says the property we are interested in does exist but don't know if Fibre can be provided.
It used to be a Talk Talk line, so I asked them. Naturally they say fibre is not available.
Then I tried BT openreach and surprise surprise, all three can have fibre.
Is it just no working phone means until one is installed, dial up might work or that is the time when all will become clear - but, of course, you can't order something that does not exist.

What have I missed?

Are uou checking using house number, address and postcode?

It's a house name and putting in the post code, get a choice of all properties. Two come with with fibre available and the third just says:
Your address has been successfully matched; however we cannot determine ADSL availability at this address. Please try the Telephone Number or Postcode Checker.
No phone number and post code says ADSL2 but does come from Swadlincote exchange cabinet 23 (same as the other two properties.

With the cannot determine, it just means computer is saying not sure, so needs retailer to put in a manual check request usually.

If they had FTTC previously then most likely will resolve once any cease orders have completed.

One of the other properties was complaining that his broadband was very slow, but I didn't ask if he had fibre or not.
If/when we exchange, I'll have another go.

What FTTC estimates does it give for the other two?

FTTC Range A (Clean) 48.7 33.8 10.1 6.4 -- Available
FTTC Range B (Impacted) 40.3 24.1 10.1 5 -- Available

So you should be fine for decent speeds once the order side is sorted, and either the neighbour has a poor wireless setup, or poor house wiring, or some sort of fault.
