If your license is issued by theUK CAA you are governed by CAP393.
PArt 8 section 79 gives you what to record and T/O and landings isn't one of the requirements.
Thats not to say you can't log them if you feel like it.
There is a requirement to record landings for certain ratings and tests eg night ratings and base checks. But thats about it for a Brit license holder.
And this PICUS nonsense don't go near it with Captains unless its brought up by them and then just agree with them. I have just had to set up 3 different processes for PICUS logging for different NAA's license holders.
I have 1 NAA that requires them to be on a command upgrade course flying in the LHS.
1 That requires it to be done only with a TRI/TRE.
1 That it can be done with a line trainer.
And of course the easy Brit option which we never know what the FO logs and a letter from OPS saying the hours are correct is good enough.
BTW I have never logged PICUS I got my PIC hours in a spam can VFR instructing which taught me sweet FA about operating a commercial airliner. So I really can't get my knickers in a twist about FO's logging PICUS when handling.
