I get something called the work related activity component (I think that's the term) of just under £30 per week which IIRC I didn't get initially on ESA but started being awarded after being placed into the WRAG. Again, if I've understood it correctly, this isn't payable to claims made after April 2017. I wasn't aware of this at the time of applying so if I've read it correctly I was "lucky" into having to stop working in Feb 2017 as opposed to a couple of months later.
