Following on from my last post, I came across this which helps checking if you are going to run into issues with the HMRC when you return to the UK:-
SRT: Statutory Residence Test Toolkit
Depending on the number of tests you tick, the time you are allowed to spend in the UK varies between 182 days & just 16. I found this toolkit useful since in my case I ticked two boxes and was in the UK for 49 days during the 19-20 tax year. This confirmed that I remained non-resident for that period.
Cheers
