Yes,
But If you've been on Illness Benefit for 9 months and want to go back to work, here's what you need to know:
You can't work while on Illness Benefit, so you'll need to stop it if you want to look for jobs.
Once you stop Illness Benefit, you can apply for Jobseeker's Allowance, which is for people looking for work.
If your health gets worse again and you can't work, you can apply for Illness Benefit again. But you'll need to meet the requirements:
Be younger than pension age
Get a doctor's note saying you can't work
Have enough work history (usually at least 2 years of paying into the system)
But note , If you've been on Illness Benefit for a long time before (1-2 years), you might need to have worked and paid into the system for at least 13 weeks since then to qualify again.
