The simple answer is no as no ISP in the UK supports upload speeds. All connections are sold on download speeds. That said if an upload of to lower a speed makes your download unsusable then something would have to be done.
What are your current up/down speeds?
17.5 Down and 2.3 up
That download speed is very low, so that will affect upload as well, as the two are related.

Althogh you upload speed is low so is your download, it is however within the rates given by the checker.
I can't see anything being done about it. You must be a fair distance from the cabinet.
