If
you have access to a computer look up:
LawWorks
https://www.lawworks.org.uk/legal-advice-individuals
If you do not have a computer, your local library may have computers you can use.
You can search for a Law centre near to you,
where you can get assistance with Benefits.
I found 15 Law centres within 10 miles of where
I live.
This is a short video from Mary Ward Centre, London.
