Broadband and fibre upload speeds are always lower than download speeds (if you need symmetric speeds, take a look at BTnet leased lines).
As with download speed, upload speed depends on a number of factors including -
- line quality
- distance between your broadband or fibre socket and the green street cabinet
- distance of the cabinet to your local exchange
- the age and type of your router
- correct installation of any broadband micro-filters
How do I test my broadband connection speed?
