Since they are not mentioned at all on here, I would have to assume they are possibly a reseller, or only part own/lease pipes from a wholesaler (such as Netservices). This site ONLY lists ISPs who have their own direct pipe.
My own Isp Fireflyinternet does not appear on here yet is highly rated on other sites, but it does not physically "own" it's own BT central pipe. It buys / leases dedicated pipes from Netservices - note this is different from reselling Netservices own offering, or sharing pipess with various other Isps.
Firefly did actually consider offering to wholesale some of it's capacity to the smaller Isps that Netservices are now ditching, but decided it was an unnecessary business risk.
