Migrating from legacy benefits to Universal Credit can be a significant change, especially if you are used to the old system. It's important to understand that when you migrate, your benefit amount may be reassessed, which could result in a different payment. You will need to complete a new application for Universal Credit, and it’s advisable to prepare for a possible gap in your payments during the transition. For detailed guidance and support tailored to your circumstances, consider visiting the official gov.uk page or speaking with a welfare advisor.
