How about this from P.55 of the draft bill. It looks like in principle they are allowing themselves to collect pretty much anything.

(9) In this Part “relevant communications data” means communications data
which may be used to identify, or assist in identifying, any of the following—
(a) the sender or recipient of a communication (whether or not a person),
(b) the time or duration of a communication,
(c) the type, method or pattern, or fact, of communication,
(d) the telecommunication system (or any part of it) from, to or through
which, or by means of which, a communication is or may be
transmitted,
(e) the location of any such system, or
(f) the internet protocol address, or other identifier, of any apparatus to
which a communication is transmitted for the purpose of obtaining
access to, or running, a computer file or computer program.
In this subsection “identifier” means an identifier used to facilitate the
transmission of a communication
