Not sure if anyone fancies signing up to YouGov.
Well-known and reasonably reputable polling company (I say reasonably, because very occasionally you wonder how a question got through their approval process!).
You usually get 25 or 50 points for a survey, along with some prize draw ones. Once you get to 5000 points you can convert it to £50 cash - I’ve managed this a couple of times.
If you sign up with my link and complete 6 surveys, I’ll get 200 points (yay! £2!) and you get the joy of doing the surveys… )
