OK, so i wasn't happy with the level of service being provided regarding P2P and phoned technical support to get some straight answers.
I said i was getting around 8kb/sec during the day on popular torrents such as linux distros and about 10-12kb/sec during the night. The operator i spoke to was not aware of exactly how they cap and said there were too many variables but had hoped that it would be a bit higher than that.
So no straight answers.. i'v upgraded to premier, with a static IP and i hope to see a speed increase straight away. If not, i'll be going elsewhere of course.
Hope this slight extra information helps someone, somewhere.
