Hi Helen N
Welcome to the forum
They will have your old application but you do need to complete the application form, if you need more time, contact DWP before the due date and ask for an extension.
If you kept a copy of your previous application form, which we always advise claimants to do, then use it as a template when completing the form and make any amendments necessary such as any new conditions, change in medications. Don't forget to use our latest guide to help you complete the form.
