ESA & voluntary work

I've realised that I haven't declared my voluntary job and now worried its going to cause me trouble. I had a lot of hassle from DWP about still living with ex-partner and therefore needing a visit (which hasn't happened) so although my claim dated back to early February i only received payment last month. So between having DWP pushing me to move out, doing PIP claim, i didn't think to query when they didn't ask
. Is it the PW1 form i need to submit or do i just call them?

I've volunteered in this job for nearly a year as a way to push my comfort zones and help with a reference for when i am able to properly work. I was a client previously & offered to help out so it isn't for a charity. I do under 16hrs and they cover my expenses so i'm not out of pocket and like paid staff i can have some free treatments if i choose to.

I'm also concerned with both ESA & PIP it may appear that i am more able because of volunteering. I do have to do things i've said on PIP i find difficult like mixing socially and dealing with complex information (i have trouble concentrating/memory) but its fairly quiet & i have the option to avoid any tasks i don't feel upto and not sure my work level would be acceptable if paid.

Thanks Gordon

I understand, so is it unpaid work rather than voluntary as a for profit company benefits. Unfortunately there wasn't any charity opportunities i could manage near home, but suspect the assumptions would still be made on capabilities.

I've not had an assessment yet which is what concerns me, so would i be better off giving the job up?
I don't really want to as its been beneficial to my recovery & added to my support network but equally its not representative of what i could manage doing a similar job elsewhere as few places have this set up nor could i support myself on hours i can manage.

Not that i wish to withhold information, but If i inform them now about the job won't they make still make those assumptions even if i give reasons for leaving as not coping etc?

Unfortunately as i'm trying to move & will lose the help/support i still get from ex in order to get out & about I expect my mental health conditions will decline as i try go it alone. Had hoped job would provide a little stability as its more of a day out for me, but think i'll have to try replace it with something more benefits friendly.
