Providing the DWP have received notification of your appeal you can request you are switch onto the ESA Assessment rate while you wait for a hearing. You need to contact the DWP office that was dealing with your ESA claim and make the request, you shouldn't have to close your JSA claim, the DWP will do this for you.
You will need to provide a Fit Note to enable payments and maintain one with DWP until your hearing.
If you are receiving the Disability Premium with your JSA, then be aware that this is not payable with ESA so you will receive less on ESA.
