You appear to be running your business on a residential line instead of the more expensive business connection with a better SLA
Yes its Fibre to the cabinet at the moment but with some jigegry pokery with wires but i may be wrong clearly buy what everyone is saying.,
If you look on what I recommended before you should be able to tell what you have.

Or post a screenshot with the phone number/address etc. removed and we will be able to tell you.
I should have added that images go into quarantine until a moderator releases them. While you can see it, it may be a while before the rest of us can see it and give you an answer.
I can see it now. Unfortunately, it is really too small to make out the detail but I can see it makes mention of G.Fast near the top, so I would bet that will be what you are on.
I can't really make out the stuff under that, but "FTTP on Demand" is a business product where you have to pay significantly toward the installation cost. Possibly several thousand pounds. I suspect that will be a non-starter for you.
What are the other options under that? Do any of those make mention of FTTP?
No, you'll have the link, that's why it goes full screen. I just get the image. I did copy it and enlarge it but is is too blurry to read.
If it says no FTTP that's probably it. What you can do, though, is declare an interest with Openreach. They'll then email you updates about what is going on. They tell you when it is available, (probably a couple of weeks before BT's website says it is). Openreach's website is here:

You should be able to just click on the picture and it should enlarge. If it doesn't do that it might be a browser setting that is stopping it. Try a different browser.
