Before applying, gather your National Insurance number, identity documents, bank or building society details, rent and housing costs, and information about your income and savings. You may also need details of your partner, children, childcare costs, health conditions and any other benefits you receive. Make your claim through the official GOV.UK Universal Credit service and keep your login details safe, as you will usually need to manage tasks in your online account. Check GOV.UK for the latest requirements, because the information requested can depend on your circumstances.
