Hi declan1,
I'm afraid I don't know anything about this. I have managed to find a website which might help.
www.litrg.org.uk/tax-guides/self-employm...at-trading-allowance It seems this is more of a tax break than something to do with ESA.
UC will take this into account, I think probably because you can work and claim UC as it replaces tax credits.
I'm not sure what happens with ESA/HB, but it is likely that if you have income this may preclude ESA or HB.
PIP is not means tested so will not be affected.
I'm sorry I can't help further.
