Are you sure FTTP is actually in your area, since having an exchange that supports it is not the same as being covered by the service itself? Otherwise it depends which FTTP supporting ISP you choose, BT's checker should tell you if they can do it or you might wish to call AAISP, Zen or IDNet directly to enquire. Claranet Soho also do some FTTP.
Sadly there aren't many FTTP providers for home users and so most are more business focused.
