As far as I can tell, bulk collection does require a warrant (as per the bulk powers section) and is limited to security / intelligence agencies (does that include police?).
Police have to request the ICRs for an individual on a case-by-case basis, going through a 'senior officer' who takes advice from a single point of contact (SPoC), although I can't find any criteria for SPoC selection.
In any case, there's no judicial oversight on ICR requests as far as I can see.
