35Mbps down, 9.1Mbps up according to the router.
It started out at 40/10 a few years ago (original guess of the BT ADSL checker site thing was that the address could handle 47-53 if I recall correctly, but it obviously wasn't enough for me to opt for 80/20 over the 40/10 if I wouldn't be able to actually get much more than the 40), but it seems to have got lower over the past year.
