Many funds are not listed in quote sources, or not with any regularity.

I just got data for one from Alphavantage: symbol=GB00BJ04HW53.L (which 
is Invesco Perpetual Income Y Accumulator). However, the "last refreshed" 
date is 27 April, making it of doubtful use (and a lot of dates show 
zeros, suggesting Alphavantage didn't get values on those dates).
