how is the cable going to be run? are you using SWA? if SWA, how are you going to gland off and make connections to flex for lights? RCD protection?.a bit more info is needed.

Yeah sorry not very clear it will have 30ma rcd protection from garage CU and will run under ground 4 meters then clipped direct to wooden fence to adaptable box then plastic conduit to lights via FCU then S/O this part I'm wiring in singles and will connect flex in through boxes

2.5mm will be fine on a 16A or a 20A MCB.
