How do I contact ACAS to fill in the form?

Use the official ACAS notification form

ACAS publishes the notification form on its own website. Start it here:

Notify ACAS about making a claim to an employment tribunal

ACAS states that once you submit the form you can no longer access or amend it, so check your answers before submitting. ACAS also provides a route to return to a form you have started but not yet submitted.

Getting help while you complete it

The ACAS helpline is for employment law and work advice for employers and workers. Helpline advisers can explain what the law says and discuss options, including the risks and benefits. They cannot take sides, give a legal opinion or act on your behalf.

• Helpline: 0300 123 1100, Monday to Friday, 8am to 6pm.
• Relay UK text relay: 18001 0300 123 1100, if you cannot hear or speak on the phone.
• Interpreters: call the helpline and ask for an interpreter. ACAS also offers a British Sign Language video relay service.
• Accessibility: ACAS has an accessibility form for asking for advice another way if you cannot call.

Full details are on the ACAS helpline page.

A helpline call is not notification

Speaking to the ACAS helpline does not start early conciliation and does not protect your tribunal time limit. Notification happens when you submit the notification form.

Check the date that applies to you on the ACAS deadline tracker, and see when you can fill in the ACAS form.

After you submit the form

ACAS sends a confirmation with your reference number, reviews the details and assigns a conciliator. ACAS states the service is very busy and that conciliation can take around 9 weeks to start. If you are already in conciliation and have a question about your case, contact your conciliator using the details in the email ACAS sent you.
