If you disagree with a decision about your Universal Credit claim then the first thing you should do is contact your local job centre using the details on your decision letter and ask for an explanation of the reasons behind a decision. You should do this as soon as possible.
Once you have received an explanation you still believe the decision is wrong then you can ask for the Department of Work and Pensions to look at it again this is known as a ‘mandatory reconsideration’.
You will need to do this within one month of the date of the decision.
