You can apply for Universal Credit online.
Before you apply, check if you are eligible and what you can get.
You might also need to book and attend an interview at your local Jobcentre Plus. You will be told if you need to after you apply.
You will get your first payment around five weeks after applying online if your application is successful. When you apply, you can ask for an advance if you need help sooner.
