ESA3 form

If you’re in the work-related activity group and get contribution-based ESA, you’ll only get it for up to a year. This includes time before your medical assessment. When you’re almost at the end of the year, you’ll be sent an ESA3 form to fill in to see if you can be moved onto income-related ESA instead. If your disability or illness gets worse and you would qualify for the support group, you can ask the DWP to re-assess you even after the year’s finished.
If you’re in the support group or getting income-related ESA, your claim will be ongoing.

The DWP will usually re-assess your ability to work every 1, 2 or 3 years to make sure you’re still not fit to work.
If you’re in the support group, the DWP might decide they won’t need to re-assess you in future - they’ll tell you in the decision letter they send you. They’ll only do this if your condition’s unlikely to improve much in the future, and this means you’ll always be in the support group.
