your best option is to get an engineer out who knows area.
when they are sent out they will have an order which will tell them exacly how long your line is.
BB speed depends on line length but also diameter of copper used.
on average BB will work upto 9km but wont be fast.
also the engineer will only check up until the NTE and not past it.
if you want it checked after NTE you will be charged.
if you are being told that your line is long, chances are it is.
as far as sky is concerned they do not supply all exchange areas with their BB. if they do not they will charge more for their package as they have to rent the equipment from another provider. they will supply sky router which is probably what you are picking up.
you should get an engineer to visit its the best and easiest option
