Hi Sally
Welcome to the forum.
You might want to have a look at the following FAQ which explains where everything is;
www.benefitsandwork.co.uk/guides-for-claimants/faq/forum.
An interesting question, I have no idea. It depends on a number of factors such as what region you live in, I cannot remember on the forum when a UC appeal question came up.
Fellow members may be able to assist you.
