If you are on an LLU service already in any shape than it would go through as a new line regardless of provider. Unless the service happened to be on the same LLU operator.
Who are you currently with? If it's TalkTalk, o2, BE etc then it's probably some form of LLU. If not completely LLU in some cases.
