ntl have peering arrangement's with various isp's for that kind of traffic level3,abovenet and cogent are the 3 big ones they use for us transit but there are more. Also because they use proxies ntl will also have alot of requests just been kept internally on their network for cached pages. Even traffic within the uk will most likely involve other isp's, about the only few cases your traffic wont leave ntl (or telewest) is if the site itself is hosted on their network or cached. All non http traffic wont be cached.
