Yes, you can update your application after submitting it, depending on the changes you want to make. For example, you can add people to form a joint application or change from a joint to a sole application if needed. However, if you need to make significant changes or if your application becomes non-active for any reason, you may have to complete a change of circumstances form.
Here's a summary of the types of changes you can make to your application:
| Change Type | Action Required |
|---|---|
| Add people to your application | Reassess and update to include new joint applicant |
| Remove people from your application | Complete a change of circumstances form |
| Change from a joint to sole application | Main applicant retains number; other applicant must reapply |
If you're looking to make changes, I recommend checking the specific guidance from Welwyn Hatfield about managing your application for further details. You can find more information here.
