You have to notify SW if there’s a change in your circumstances while you’re
claiming a SW payment.

As you’re not available now for full time work you’re no longer eligible for Jobseekers.
Depending on a number of factors, you may be eligible for BTWEA.

You have to reach out to and make contact with an officer in your local SW office.
You need to search citizensinformation.ie for “Back to Work Enterprise Allowance” to get all the information you need.
The document is very thorough giving you details of all the grants that are available to you as a new start up.
You also need to contact your “Local Enterprise Office” as part of the process.
You’ll find yours at whichever is your Local Authority. (County Council website).
This is all explained in the citizensinformation.ie document, as is the application form.
