I know lots of people in this situation
All of them went for SKY LLU (assuming it's available).
What Sky can do is provide the line and the broadband simultaneously so that they both connect at the same time.
& Sky are very cheap on LLU.
Not sure about other providers. Just talking about first hand experience with family.
