I think you probably mean 1Mb/s - the lower case b is very significant when talking speeds.
That is exactly what i meant, thank you for the correction.
I can't even speak to openreach, I have tried in the past. The letting agency has the same problem, can't get to speak to anyone at openreach.
I have received an email back from the letting agency since my first post. Bovis Homes was the contractor that built the property, and they haven't installed fiber around the block itself, and are not willing to do so. We have fiber into the block (have just checked, Fiber cables are cut and not going anywhere but are coming in from outside).
Their are 7 flats in the block. Who is it best to contact, as landlord is going to have to get fiber cabling installed around the block. The letting agency is looking at ways to get this done as well, but have had no luck with openreach as can't speak to anyone.
