CAA's master version of CAP371 is
here. Scroll down to page 21 and Table A Two or more flight crew - Acclimatised. Max Flight Duty Period is based on local time of start and number of sectors.
You're right that there is no daily limit to flying hours in UK per se, it is limited by the duration of your FDP which , if you have a one hour report time, could mean you are doing 13 flying hours (although see the next page on limits on two crew long range ops). Limitations on pure flying hours are only applied on a rolling 28 day and annual basis.
