Since we have determined that the cable is clipped direct outside and HHD has repeatedly in other threads identified the cables he would use outside as "outside and 99% of the time I use black rubber flex (in particular H05RN)" and since this is from the nature of the jobs done a domestic installation and HO5RN is suitable for medium severity impact as it is a heavy duty cable then one can be fairly sure that this installation is fine as described and does not need RCD protection, mechanical protection (which can be of various sorts. including capping, depending on the requirements for that protection) or anything else.
